Organization Consolidation And Presentation Of Financial Statements [Abstract]
General	NOTE A – General Business Description SPS Commerce is a leading provider of cloud-based supply chain management services across our global retail network. Our products make it easier for retailers, suppliers, grocers, distributors, and logistics firms to orchestrate the management of item data, order fulfillment, inventory control, and sales analytics across omnichannel retail channels. SPS Commerce delivers our products using a full-service model whereby our internal experts monitor, update, and boost network performance on our customers’ behalf. The services offered by SPS Commerce eliminate the need for on-premise software and support staff by taking on that capability on the customer’s behalf. The services SPS Commerce provides enable our customers to increase their supply cycle agility, optimize their inventory levels and sell-through, reduce operational costs and gain increased visibility into customer orders, ensuring that suppliers, grocers, distributors, and logistics firms can satisfy exacting retailer requirements. Basis of Presentation The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of SPS Commerce, Inc. and its subsidiaries. All intercompany accounts and transactions have been eliminated in the consolidated financial statements. On July 25, 2019, we announced that our board of directors declared a two-for-one stock split of our common stock, effected in the form of a 100 percent stock dividend as of the record date on August 8, 2019. The stock split dividend was distributed on August 22, 2019. Earnings per share and weighted average shares outstanding are presented in this Annual Report on Form 10-K after the effect of the 100 percent stock dividend. The two-for-one stock split is reflected in the share amounts in all periods presented in this Annual Report on Form 10-K. Foreign Currency Translation The functional currency of our foreign operations is generally the applicable local currency. The functional currency is translated into U.S. dollars for balance sheet accounts using current exchange rates in effect as of the balance sheet date and for revenue and expense accounts using an average exchange rate during the year. The translation adjustments are deferred as a component of other comprehensive income within the consolidated statements of comprehensive income and the consolidated statements of stockholders' equity. Gains or losses resulting from transactions denominated in foreign currencies are included in other income (expense), net in our consolidated statements of comprehensive income. Use of Estimates Preparing financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Business Combinations We recognize the fair value of the assets acquired and the liabilities assumed at the acquisition date, separately from goodwill. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the amount of the assets acquired and the liabilities assumed. Assets acquired include tangible and intangible assets. We use estimates and assumptions that we believe are reasonable as a part of the purchase price allocation, which includes the process to determine the value and useful lives of purchased intangible assets and the process to determine the value of any contingent consideration liabilities. We record the acquisition-date fair value of any contingent liabilities, such as earn-out provisions, as part of the consideration transferred, if present. The unsettled earn-out liability, if any, fair value is subsequently remeasured at each reporting date. While we believe these estimates and assumptions are reasonable, they are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we may record adjustments to the fair value of the assets acquired and the liabilities assumed . Any such adjustments would be recorded capital adjustment as applicable. Upon the conclusion of the measurement period or final determination of the fair values, whichever comes first, any subsequent adjustments would be recorded in our consolidated statements of comprehensive income. Segment Information Our Chief Executive Officer acts as the Company’s chief operating decision maker and reviews financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. There are no segment managers who are held accountable by the chief operating decision maker, or anyone else, for operations, operating results and planning for levels or components below the consolidated unit level. Accordingly, we determined we have one operating and reportable segment, which is supply chain management products. Concentration of Credit Risk Financial instruments that potentially subject us to concentrations of credit risk consist principally of cash and cash equivalents in financial institutions in excess of federally insured limits and accounts receivable. Cash and cash equivalents are held with financial institutions that we believe are subject to minimal risk. Cash and Cash Equivalents Cash and cash equivalents consist of cash and highly liquid investments with original maturities of less than 90 days. Investments We invest in money market funds, certificates of deposit, highly liquid debt instruments of the United States (“U.S.”) government and U.S. corporate debt securities. Investments with remaining maturities of less than one year from the balance sheet date are classified as Short-term investments whereas those with remaining maturities of more than one year from the balance sheet date are classified as Investments, non-current. We determine the appropriate classification of certificates of deposit and marketable securities at the time of purchase and reevaluate such determination at each balance sheet date. Securities classified as available for sale are carried at fair value and the unrealized gains and losses on these investments, net of taxes, are included in accumulated other comprehensive loss in the consolidated balance sheets. Realized gains or losses are included in other income (expense), net in the consolidated statements of comprehensive income. Certain securities accrue interest that is included in other income (expense), net. When a determination has been made that the fair value of a marketable security is below its amortized cost basis, the portion of the unrealized loss that corresponds to a credit-related factor is realized through a credit allowance on the marketable security and the equivalent expense is realized in other income (expense), net in the consolidated statements of comprehensive income. Fair Value of Other Financial Instruments The carrying amounts of our short-term financial instruments, which include cash, cash equivalents, accounts receivable, and accounts payable, approximates fair value due to their short-term nature. Accounts Receivable Accounts receivable are initially recorded upon the sale and invoicing of products to customers. Credit is granted in the normal course of business without collateral. Accounts receivable are stated net of allowances for credit losses, which represent estimated losses resulting from customers not making required payments on accounts receivables. When determining the allowance, we pool our outstanding accounts receivable invoices based on the contractual due date of payment. We for estimated credit losses by pool, primarily historical credit losses, additional adjustments made for current and future macro-economic conditions and retail bankruptcy trends. Property and Equipment Property and equipment, including assets acquired under capital lease obligations, are stated at cost, net of accumulated depreciation and amortization. Depreciation and amortization expense is calculated using the straight-line method over the estimated useful lives when placed in service. We capitalize and amortize eligible costs to acquire or develop internal-use software that are incurred during the application development stage. Costs incurred during the preliminary project stage and post-implementation stage are expensed as incurred. Amortization expense for internal-use sof t ware is calculated using the straight-line method over the estimated useful life, c ommencing on the date when the asset is ready for its intended use. The estimated useful lives of property and equipment were as follows: Estimated Useful Life Computer equipment and software 2-3 years Office equipment and furniture 5-7 years Leasehold improvements Shorter of the useful life of the asset or the remaining term of the lease Internal-use software 3 years Significant additions or improvements extending asset lives beyond one year are capitalized, while repairs and maintenance are charged to expense as incurred. Maintenance and enhancements of internal-use software are expensed as incurred. The assets and related accumulated amortization are adjusted for abandoned internal-use software with the resulting gain or loss included in our consolidated statements of comprehensive income. Leases We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use assets, current operating lease liabilities, and long-term operating lease liabilities in our consolidated balance sheets. Right-of-use (“ROU”) assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. We use the implicit interest rate when readily determinable. We estimate the discount rate for a similar collateralized asset by estimating costs of borrowing. The operating lease ROU asset also includes any lease payments made and lease incentives that have been incurred. The options to extend our leases are not recognized as part of our ROU assets and lease liabilities unless it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. For all leases, we combine non-lease components with the related lease components and account for it as a single lease component. The ROU assets are subject to the same impairment process as our long-lived assets. Additionally, we review our lease liabilities for remeasurement whenever there is a triggering event or when relevant facts and circumstances change. Research and Development Research and development costs primarily include maintenance and data conversion activities related to our cloud-based supply chain management products and are expensed as incurred. Goodwill Goodwill represents the excess of the purchase price over the fair value of identifiable net assets acquired in business combinations. We test goodwill for impairment annually at November 30, or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test is conducted by comparing the fair value of the net assets with the carrying amount of the reporting unit. We determine the fair value of the reporting unit based on our market capitalization at the testing date. If the carrying amount exceeds the fair value of the reporting unit, we would recognize an impairment loss in the consolidated statements of comprehensive income, to the extent that the carrying amount exceeds fair value. Intangible Assets Assets acquired in business combinations may include identifiable intangible assets such as subscriber relationships and developed technology. We recognize the fair value of the identifiable intangible assets acquired separately from goodwill. We have determined the fair value and useful lives of our purchased intangible assets using certain estimates and assumptions that we believe are reasonable. The purchased intangible assets are being amortized on a straight-line basis over their estimated useful lives. The estimated useful lives for intangible were as follows: Estimated Useful Life Subscriber relationships 7-10 years Acquired technology 3-10 years Third-Party Implementation Assets Third-party implementation costs are capitalized assets included in Other Assets and relate to implementation costs incurred for software hosting arrangements. Capitalized implementation costs are recognized on a straight-line basis beginning when the application is ready for its intended use and ending on the expected termination date of the hosting arrangement, including consideration of the noncancelable contractual term and reasonably certain renewals. The original terms are between four and six years for our current hosting arrangements. Recognized expense is reported in general and administrative expense, which is where the hosting arrangement subscriptions are reported. Impairment of Long-Lived Assets We review our long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. The carrying amount of a long-lived asset is not recoverable if the carrying amount of an asset group exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the assets at the date it is tested for recoverability, whether in use or under development. An impairment loss is measured and recorded as an expense in the consolidated statements of comprehensive income as the amount by which the carrying amount of a long-lived asset exceeds its fair value. Revenue Recognition Revenues are the amount that reflects the consideration we are contractually and legally entitled to, as well as expect to collect, in exchange for those services. We determine revenue recognition through the following steps: • Identification of the contract, or contracts, with a customer • Identification of the performance obligations in the contract • Determination of the transaction price • Allocation of the transaction price to the performance obligations in the contract • Recognition of revenue when, or as, we satisfy a performance obligation See Note C for further descriptions of our revenue recognition policy. Deferred Costs Deferred costs are those that are incurred to fulfill or obtain customer contracts and that are considered incremental and recoverable costs. These consist primarily of customer implementation costs, commissions paid to sales personnel and third-party partners for customer referrals, respectively. These costs are deferred and amortized over the expected period of benefit which we have determined to be two years. Customer implementation costs are based on actual costs Sales commissions are calculated based on estimated annual recurring revenue to be generated over the customer’s initial contract period. Related amortization expense is included in sales and marketing expenses in the consolidated statements of comprehensive income. Stock-Based Compensation We recognize the cost of all share-based payments to employees, executive officers, and non-employee members of the Company’s Board of Directors, including grants of incentive and nonqualified stock options, performance share units (“PSUs”), restricted stock awards (“RSAs”), restricted stock units (“RSUs”), deferred stock units (“DSUs”), employee stock purchase plan (“ESPP”) activity, and 401(k) stock match in the consolidated financial statements based on the grant date fair value of those awards. This cost is recognized over the period for which an employee is required to provide service in exchange for the award or the award performance period , except for expense s relating to retirement-eligible employees that have not given their required notice, which is recognized on a pro-rata basis over the notice period prior to retirement. RSAs result in the issuance of new shares when granted. For other stock-based awards, new shares are issued when the award is exercised, vested, or released according to the terms of the agreement. The fair value of stock options and ESPP activity is estimated using the Black-Scholes-Merton option valuation model. The fair value for RSAs, RSUs, and DSUs is the closing market value of the underlying stock on the date of grant less the purchase price (if any). The fair value of PSUs is estimated using a Monte Carlo simulation. In valuing share-based awards, excluding PSUs, judgment is required in determining the expected volatility of common stock and the expected term individuals will hold their share-based awards prior to exercising. The expected volatility of the options is based on the historical volatility of our common stock. Beginning with awards granted in 2020, the expected term of the options is derived from historical data on option holder exercises and post-vesting employment termination behavior. For awards granted prior to 2020, the expected term of the options was based on the simplified method. Additional valuation inputs include our expected non-issuance of future common stock dividends and the risk-free interest rate that is based on the U.S. Treasury rates at the date of grant with maturity dates approximately equaling the expected life at the grant date. For PSUs, t he Monte Carlo simulation utilizes multiple input variables that determine the probability of satisfying the performance conditions stipulated in the award. For all awards, w Income Taxes We account for income taxes using the asset and liability method, which requires recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance when, in our judgment, it is more likely than not that some or all of the deferred tax asset will not be realized. We assess our ability to realize our deferred tax assets at the end of each reporting period. Realization of our deferred tax assets is contingent upon future taxable earnings. Accordingly, this assessment requires estimates and judgment. If the estimates of future taxable income vary from actual results, our assessment regarding the realization of these deferred tax assets could change. Future changes in the estimated amount of deferred taxes expected to be realized will be reflected in our consolidated financial statements in the period the estimate is changed, with a corresponding adjustment to our operating results. We recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would “more likely than not” sustain the position following an audit. For tax positions meeting the “more likely than not” threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant tax authority. It is our practice to recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. Net Income Per Share Basic net income per share has been computed using the weighted average number of shares of common stock outstanding during each period. Diluted net income per share also includes the impact of our outstanding potential common shares, including options, RSAs, RSUs, PSUs, DSUs and ESPP activity. Potential common shares that are anti-dilutive are excluded from the calculation of diluted net income per share. Accounting Pronouncements Not Yet Adopted Standard Date of Issuance Description Date of Required Adoption Effect on the Financial Statements ASU 2021-08 , Business Combinations (Topic 805) - Accounting for Contract Assets and Contract Liabilities from Contracts with Customers October 2021 This amendment requires that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, effective for all business combinations in the year of adoption and thereafter. January 2023 The adoption of this standard may have a material impact on the purchase accounting for business combinations depending on the specific amount of contract assets and liabilities being acquired.

Business Combinations [Abstract]
Business Acquisitions	NOTE B – Business Acquisitions Genius Central On November 3, 2021, we merged with and correspondingly acquired all of the outstanding equity ownership interests of Genius Central Systems Inc. (“Genius Central”), a leading provider of order processing services and other supply chain products in the natural product industry. Pursuant to the membership interest purchase agreement, given a target working capital level, the total transaction price was $17.4 million. $17.3 million was paid in cash at closing and $0.1 million is due to the sellers as part of the initial net working capital adjustment. Purchase Price Allocation We accounted for the acquisition as a business combination. We allocated the purchase price to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date. The excess of the purchase price over the fair value of net tangible and identifiable intangible assets acquired was recorded as goodwill. Goodwill is attributed to a trained workforce and other buyer-specific value resulting from expected synergies, including long-term cost savings, which are not included in the fair values of identifiable assets. The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the acquisition date: (in thousands) Estimated Fair Value Cash $ 205 Accounts receivable, net 353 Deferred tax assets 1,877 Other current and non-current assets 115 Goodwill 8,914 Intangible assets 8,500 Current liabilities (238 ) Deferred revenue (146 ) Deferred tax liabilities (2,167 ) $ 17,413 Purchased Intangible Assets The following table summarizes the estimated fair value of the purchased intangible assets and their estimated useful lives: Weighted Average Estimated Estimated (in thousands, except weighted average estimated useful life) Fair Value Useful Life Subscriber relationships $ 6,400 9 years Acquired technology 2,100 7 years Total $ 8,500 Data Masons In December 2020, we acquired all of the outstanding equity ownership interests of D Masons Software, LLC (“Data Masons”). As of December 31, 2020, the purchase accounting for the acquisition was not finalized. During 2021, the only change in the purchase accounting was a $0.3 million reduction of amounts due from the seller as part of the initial net working capital adjustment and a corresponding increase to goodwill.

Revenue From Contract With Customer [Abstract]
Revenue	NOTE C – Revenue We derive our revenues from the following revenue streams: Year Ended December 31, (in thousands) 2021 2020 2019 Recurring revenues: Fulfillment $ 306,851 $ 251,272 $ 219,297 Analytics 42,674 38,824 37,038 Other 5,481 4,920 5,671 Recurring Revenues 355,006 295,016 262,006 One-time revenues 30,270 17,614 17,118 Total revenue $ 385,276 $ 312,630 $ 279,124 Revenues are the amount that reflects the consideration we are contractually and legally entitled to, as well as expect to collect, in exchange for those services. Recurring Revenues Recurring revenues consist of recurring subscriptions from customers that utilize our Fulfillment, Analytics and Other supply chain management products. Revenue for these products is generally recognized on a ratable basis over the contract term beginning on the date that our service is made available to the customer. Our contracts with our recurring revenue customers are recurring in nature, ranging from monthly to annual, and generally allow the customer to cancel the contract for any reason with 30 to 90 days’ notice. Timing of billings varies by customer and by contract type and are either in advance or within 30 days of the service being performed. The recurring revenue contracts are for one year or less and recognized on a ratable basis over the contract term. We have applied the optional exemption to not disclose information about the remaining performance obligations for recurring revenue contracts since they have original durations of one year or less. One-time Revenues One-time revenues consist of set-up fees and miscellaneous fees from customers. Set- up revenues Set-up fees are specific for each connection a customer has with a trading partner and many of our customers have connections with numerous trading partners. These nonrefundable fees are necessary for our customers to utilize our services and do not provide any standalone value. Set-up fees constitute a material renewal option right that provide customers a significant future incentive that would not be otherwise available to that customer unless they entered into the contract, as the set-up fees will not be incurred again upon contract renewal. As such, set-up fees and related costs are deferred and recognized ratably over two years, which is the estimated period for which a material right is present for our customers. The table below presents the activity of the portion of the deferred revenue liability relating to set-up fees: Year Ended December 31, (in thousands) 2021 2020 Balance, beginning of year $ 11,118 $ 10,518 Invoiced set-up fees 15,931 11,410 Recognized set-up fees (12,590 ) (10,810 ) Balance, end of year $ 14,459 $ 11,118 The entire balance of deferred set-up fees will be recognized within two years; those that will be recognized within the next year are classified as current whereas the remainder are classified as non-current. Miscellaneous one-time revenues Miscellaneous one-time fees consist of professional services and testing and certification. The contract period for these one-time fees is for one year or less and recognized at the time service is provided. We have applied the optional exemption to not disclose information about the remaining performance obligations for miscellaneous one-time fee contracts since they have original durations of one year or less. Deferred Revenue In the year ended December 31, 2021, we recognized revenue of $37.9 million from amounts included in deferred revenue at December 31, 2020.

A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels of inputs that are used to measure fair value are: • Level 1 – quoted prices in active markets for identical assets or liabilities. • Level 2 – observable inputs other than Level 1 prices, such as (a) quoted prices for similar assets or liabilities, (b) quoted prices in markets with insufficient volume or infrequent transactions (less active markets), or (c) model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 – unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities. We obtain the fair values of our Level 2 securities from a professional pricing service. The following table details the fair value hierarchy of our assets and liabilities measured at a fair value on a recurring basis: December 31, 2021 (in thousands) Level 1 Level 2 Level 3 Total Assets: Cash equivalents: Money market funds $ 138,205 $ — $ — $ 138,205 Certificate of deposit 7,268 — — 7,268 Marketable securities: U.S. corporate bonds — — — — Commercial paper — 34,991 — 34,991 U.S. treasury securities — 7,499 — 7,499 $ 145,473 $ 42,490 $ — $ 187,963 December 31, 2020 (in thousands) Level 1 Level 2 Level 3 Total Assets: Cash equivalents: Money market funds $ 112,907 $ — $ — $ 112,907 Certificate of deposit 7,708 — — 7,708 Marketable securities: U.S. corporate bonds — 5,040 — 5,040 Commercial paper — 7,514 — 7,514 U.S. treasury securities — 20,024 — 20,024 $ 120,615 $ 32,578 $ — $ 153,193 Liabilities: Contingent consideration $ — $ — $ 1,878 $ 1,878 $ — $ — $ 1,878 $ 1,878 For the contingent consideration liability, related to the Data Masons acquisition, we were required to pay the former owners of Data Masons $1.9 million in the event the Paycheck Protection Program Loan (“PPP Loan”) acquired in the acquisition was forgiven in full. In 2021, the Small Business Administration approved the full forgiveness of the PPP Loan and, accordingly, the payment of the $1.9 million contingent liability was made. Nonrecurring Fair Value Measurements We measure certain assets and liabilities at fair value on a nonrecurring basis, including long-lived assets, goodwill, and indefinite-lived intangible assets.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Business Description	Business Description SPS Commerce is a leading provider of cloud-based supply chain management services across our global retail network. Our products make it easier for retailers, suppliers, grocers, distributors, and logistics firms to orchestrate the management of item data, order fulfillment, inventory control, and sales analytics across omnichannel retail channels. SPS Commerce delivers our products using a full-service model whereby our internal experts monitor, update, and boost network performance on our customers’ behalf. The services offered by SPS Commerce eliminate the need for on-premise software and support staff by taking on that capability on the customer’s behalf. The services SPS Commerce provides enable our customers to increase their supply cycle agility, optimize their inventory levels and sell-through, reduce operational costs and gain increased visibility into customer orders, ensuring that suppliers, grocers, distributors, and logistics firms can satisfy exacting retailer requirements.
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of SPS Commerce, Inc. and its subsidiaries. All intercompany accounts and transactions have been eliminated in the consolidated financial statements. On July 25, 2019, we announced that our board of directors declared a two-for-one stock split of our common stock, effected in the form of a 100 percent stock dividend as of the record date on August 8, 2019. The stock split dividend was distributed on August 22, 2019. Earnings per share and weighted average shares outstanding are presented in this Annual Report on Form 10-K after the effect of the 100 percent stock dividend. The two-for-one stock split is reflected in the share amounts in all periods presented in this Annual Report on Form 10-K.
Foreign Currency Translation	Foreign Currency Translation The functional currency of our foreign operations is generally the applicable local currency. The functional currency is translated into U.S. dollars for balance sheet accounts using current exchange rates in effect as of the balance sheet date and for revenue and expense accounts using an average exchange rate during the year. The translation adjustments are deferred as a component of other comprehensive income within the consolidated statements of comprehensive income and the consolidated statements of stockholders' equity. Gains or losses resulting from transactions denominated in foreign currencies are included in other income (expense), net in our consolidated statements of comprehensive income.
Use of Estimates	Use of Estimates Preparing financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.
Business Combinations	Business Combinations We recognize the fair value of the assets acquired and the liabilities assumed at the acquisition date, separately from goodwill. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the amount of the assets acquired and the liabilities assumed. Assets acquired include tangible and intangible assets. We use estimates and assumptions that we believe are reasonable as a part of the purchase price allocation, which includes the process to determine the value and useful lives of purchased intangible assets and the process to determine the value of any contingent consideration liabilities. We record the acquisition-date fair value of any contingent liabilities, such as earn-out provisions, as part of the consideration transferred, if present. The unsettled earn-out liability, if any, fair value is subsequently remeasured at each reporting date. While we believe these estimates and assumptions are reasonable, they are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we may record adjustments to the fair value of the assets acquired and the liabilities assumed . Any such adjustments would be recorded capital adjustment as applicable. Upon the conclusion of the measurement period or final determination of the fair values, whichever comes first, any subsequent adjustments would be recorded in our consolidated statements of comprehensive income.
Segment Information	Segment Information Our Chief Executive Officer acts as the Company’s chief operating decision maker and reviews financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. There are no segment managers who are held accountable by the chief operating decision maker, or anyone else, for operations, operating results and planning for levels or components below the consolidated unit level. Accordingly, we determined we have one operating and reportable segment, which is supply chain management products.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject us to concentrations of credit risk consist principally of cash and cash equivalents in financial institutions in excess of federally insured limits and accounts receivable. Cash and cash equivalents are held with financial institutions that we believe are subject to minimal risk.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash and highly liquid investments with original maturities of less than 90 days.
Investments	Investments We invest in money market funds, certificates of deposit, highly liquid debt instruments of the United States (“U.S.”) government and U.S. corporate debt securities. Investments with remaining maturities of less than one year from the balance sheet date are classified as Short-term investments whereas those with remaining maturities of more than one year from the balance sheet date are classified as Investments, non-current. We determine the appropriate classification of certificates of deposit and marketable securities at the time of purchase and reevaluate such determination at each balance sheet date. Securities classified as available for sale are carried at fair value and the unrealized gains and losses on these investments, net of taxes, are included in accumulated other comprehensive loss in the consolidated balance sheets. Realized gains or losses are included in other income (expense), net in the consolidated statements of comprehensive income. Certain securities accrue interest that is included in other income (expense), net. When a determination has been made that the fair value of a marketable security is below its amortized cost basis, the portion of the unrealized loss that corresponds to a credit-related factor is realized through a credit allowance on the marketable security and the equivalent expense is realized in other income (expense), net in the consolidated statements of comprehensive income.
Fair Value of Other Financial Instruments	Fair Value of Other Financial Instruments The carrying amounts of our short-term financial instruments, which include cash, cash equivalents, accounts receivable, and accounts payable, approximates fair value due to their short-term nature.
Accounts Receivable	Accounts Receivable Accounts receivable are initially recorded upon the sale and invoicing of products to customers. Credit is granted in the normal course of business without collateral. Accounts receivable are stated net of allowances for credit losses, which represent estimated losses resulting from customers not making required payments on accounts receivables. When determining the allowance, we pool our outstanding accounts receivable invoices based on the contractual due date of payment. We for estimated credit losses by pool, primarily historical credit losses, additional adjustments made for current and future macro-economic conditions and retail bankruptcy trends.
Property and Equipment	Property and Equipment Property and equipment, including assets acquired under capital lease obligations, are stated at cost, net of accumulated depreciation and amortization. Depreciation and amortization expense is calculated using the straight-line method over the estimated useful lives when placed in service. We capitalize and amortize eligible costs to acquire or develop internal-use software that are incurred during the application development stage. Costs incurred during the preliminary project stage and post-implementation stage are expensed as incurred. Amortization expense for internal-use sof t ware is calculated using the straight-line method over the estimated useful life, c ommencing on the date when the asset is ready for its intended use. The estimated useful lives of property and equipment were as follows: Estimated Useful Life Computer equipment and software 2-3 years Office equipment and furniture 5-7 years Leasehold improvements Shorter of the useful life of the asset or the remaining term of the lease Internal-use software 3 years Significant additions or improvements extending asset lives beyond one year are capitalized, while repairs and maintenance are charged to expense as incurred. Maintenance and enhancements of internal-use software are expensed as incurred. The assets and related accumulated amortization are adjusted for abandoned internal-use software with the resulting gain or loss included in our consolidated statements of comprehensive income.
Leases	Leases We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use assets, current operating lease liabilities, and long-term operating lease liabilities in our consolidated balance sheets. Right-of-use (“ROU”) assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. We use the implicit interest rate when readily determinable. We estimate the discount rate for a similar collateralized asset by estimating costs of borrowing. The operating lease ROU asset also includes any lease payments made and lease incentives that have been incurred. The options to extend our leases are not recognized as part of our ROU assets and lease liabilities unless it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. For all leases, we combine non-lease components with the related lease components and account for it as a single lease component. The ROU assets are subject to the same impairment process as our long-lived assets. Additionally, we review our lease liabilities for remeasurement whenever there is a triggering event or when relevant facts and circumstances change.
Research and Development	Research and Development Research and development costs primarily include maintenance and data conversion activities related to our cloud-based supply chain management products and are expensed as incurred.
Goodwill	Goodwill Goodwill represents the excess of the purchase price over the fair value of identifiable net assets acquired in business combinations. We test goodwill for impairment annually at November 30, or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test is conducted by comparing the fair value of the net assets with the carrying amount of the reporting unit. We determine the fair value of the reporting unit based on our market capitalization at the testing date. If the carrying amount exceeds the fair value of the reporting unit, we would recognize an impairment loss in the consolidated statements of comprehensive income, to the extent that the carrying amount exceeds fair value.
Intangible Assets	Intangible Assets Assets acquired in business combinations may include identifiable intangible assets such as subscriber relationships and developed technology. We recognize the fair value of the identifiable intangible assets acquired separately from goodwill. We have determined the fair value and useful lives of our purchased intangible assets using certain estimates and assumptions that we believe are reasonable. The purchased intangible assets are being amortized on a straight-line basis over their estimated useful lives. The estimated useful lives for intangible were as follows: Estimated Useful Life Subscriber relationships 7-10 years Acquired technology 3-10 years
Third Party Implementation Assets	Third-Party Implementation Assets Third-party implementation costs are capitalized assets included in Other Assets and relate to implementation costs incurred for software hosting arrangements. Capitalized implementation costs are recognized on a straight-line basis beginning when the application is ready for its intended use and ending on the expected termination date of the hosting arrangement, including consideration of the noncancelable contractual term and reasonably certain renewals. The original terms are between four and six years for our current hosting arrangements. Recognized expense is reported in general and administrative expense, which is where the hosting arrangement subscriptions are reported.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets We review our long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. The carrying amount of a long-lived asset is not recoverable if the carrying amount of an asset group exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the assets at the date it is tested for recoverability, whether in use or under development. An impairment loss is measured and recorded as an expense in the consolidated statements of comprehensive income as the amount by which the carrying amount of a long-lived asset exceeds its fair value.
Revenue Recognition	Revenue Recognition Revenues are the amount that reflects the consideration we are contractually and legally entitled to, as well as expect to collect, in exchange for those services. We determine revenue recognition through the following steps: • Identification of the contract, or contracts, with a customer • Identification of the performance obligations in the contract • Determination of the transaction price • Allocation of the transaction price to the performance obligations in the contract • Recognition of revenue when, or as, we satisfy a performance obligation See Note C for further descriptions of our revenue recognition policy.
Deferred Costs	Deferred Costs Deferred costs are those that are incurred to fulfill or obtain customer contracts and that are considered incremental and recoverable costs. These consist primarily of customer implementation costs, commissions paid to sales personnel and third-party partners for customer referrals, respectively. These costs are deferred and amortized over the expected period of benefit which we have determined to be two years. Customer implementation costs are based on actual costs Sales commissions are calculated based on estimated annual recurring revenue to be generated over the customer’s initial contract period. Related amortization expense is included in sales and marketing expenses in the consolidated statements of comprehensive income.
Stock-Based Compensation	Stock-Based Compensation We recognize the cost of all share-based payments to employees, executive officers, and non-employee members of the Company’s Board of Directors, including grants of incentive and nonqualified stock options, performance share units (“PSUs”), restricted stock awards (“RSAs”), restricted stock units (“RSUs”), deferred stock units (“DSUs”), employee stock purchase plan (“ESPP”) activity, and 401(k) stock match in the consolidated financial statements based on the grant date fair value of those awards. This cost is recognized over the period for which an employee is required to provide service in exchange for the award or the award performance period , except for expense s relating to retirement-eligible employees that have not given their required notice, which is recognized on a pro-rata basis over the notice period prior to retirement. RSAs result in the issuance of new shares when granted. For other stock-based awards, new shares are issued when the award is exercised, vested, or released according to the terms of the agreement. The fair value of stock options and ESPP activity is estimated using the Black-Scholes-Merton option valuation model. The fair value for RSAs, RSUs, and DSUs is the closing market value of the underlying stock on the date of grant less the purchase price (if any). The fair value of PSUs is estimated using a Monte Carlo simulation. In valuing share-based awards, excluding PSUs, judgment is required in determining the expected volatility of common stock and the expected term individuals will hold their share-based awards prior to exercising. The expected volatility of the options is based on the historical volatility of our common stock. Beginning with awards granted in 2020, the expected term of the options is derived from historical data on option holder exercises and post-vesting employment termination behavior. For awards granted prior to 2020, the expected term of the options was based on the simplified method. Additional valuation inputs include our expected non-issuance of future common stock dividends and the risk-free interest rate that is based on the U.S. Treasury rates at the date of grant with maturity dates approximately equaling the expected life at the grant date. For PSUs, t he Monte Carlo simulation utilizes multiple input variables that determine the probability of satisfying the performance conditions stipulated in the award. For all awards, w
Income Taxes	Income Taxes We account for income taxes using the asset and liability method, which requires recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance when, in our judgment, it is more likely than not that some or all of the deferred tax asset will not be realized. We assess our ability to realize our deferred tax assets at the end of each reporting period. Realization of our deferred tax assets is contingent upon future taxable earnings. Accordingly, this assessment requires estimates and judgment. If the estimates of future taxable income vary from actual results, our assessment regarding the realization of these deferred tax assets could change. Future changes in the estimated amount of deferred taxes expected to be realized will be reflected in our consolidated financial statements in the period the estimate is changed, with a corresponding adjustment to our operating results. We recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would “more likely than not” sustain the position following an audit. For tax positions meeting the “more likely than not” threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant tax authority. It is our practice to recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense.
Net Income Per Share	Net Income Per Share Basic net income per share has been computed using the weighted average number of shares of common stock outstanding during each period. Diluted net income per share also includes the impact of our outstanding potential common shares, including options, RSAs, RSUs, PSUs, DSUs and ESPP activity. Potential common shares that are anti-dilutive are excluded from the calculation of diluted net income per share.
