These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s final prospectus filed with the SEC pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended, on December 12, 2019 (Prospectus). Emerging Growth Company Status The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the JOBS Act). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it is (i) no longer an emerging growth company or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these condensed consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. The JOBS Act does not preclude an emerging growth company from early adopting new or revised accounting standards. The Company expects to use the extended transition period for any new or revised accounting standards during the period which the Company remains an emerging growth company. Stock Split On November 27, 2019, the Company filed an amendment to its amended and restated certificate of incorporation to effect a reverse split of shares of the Company’s issued and outstanding redeemable convertible preferred stock, common stock and non-voting 2-for-1 non-voting non-voting Segment Reporting The Company operates as one operating segment because its chief operating decision maker, who is the Chief Executive Officer, reviews its financial information on a consolidated basis for purposes of making decisions regarding allocating resources and assessing performance. All long-lived assets are located in the United States and all revenue is generated in the United States. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make various estimates and assumptions that affect the amounts reported and disclosed in the condensed consolidated financial statements and the accompanying notes. Management regularly assesses these estimates, including those related to fair value of common stock prior to the Company’s IPO and stock-based compensation, fair value of redeemable convertible preferred stock warrant liabilities up until the date of the Company’s IPO, useful lives of property and equipment, the attribution method used to recognize revenue on annual contracts, reserve for sales tax obligations, reserve for losses on funds held for customers, and income taxes. The Company evaluates these estimates and assumptions and adjusts those estimates and assumptions accordingly. Actual results could differ from those estimates, and such differences may be material to the condensed consolidated financial statements. Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, short-term investments, and accounts receivable. The Company maintains its cash and cash equivalents and short-term investments with major financial institutions that may at times exceed federally insured limits. Management believes that these financial institutions are financially sound and the Company has not experienced material losses. There were no customers that exceeded 10% of the Company’s total revenue during the three and nine months ended March 31, 2019 and 2020. Significant Accounting Policies The Company’s significant accounting policies are discussed in “Index to Consolidated Financial Statements–Note 1. The Company and its Significant Accounting Policies” in the Notes to Consolidated Financial Statements contained in the Prospectus. There have been no significant changes to these policies as described in the Prospectus.

These contracts are either cancelable arrangements paid monthly in arrears that can be terminated by either party without a penalty at any time or non-cancelable The Company’s contracts with SMB and accounting firm customers are generally comprised of a single performance obligation to provide access to the functionality of the Company’s platform to process transactions. The Company accounts for open-ended cancelable contracts as a daily service. Subscription revenue for such contracts is recognized ratably over the period that the customers have access to the platform. Transaction revenue is recognized on the date the transactions are processed by the Company. The Company accounts for its annual and monthly contracts as a series of distinct services satisfied over time. The Company determines the transaction price for such contracts by estimating the total consideration to be received over the contract term from subscription and transaction fees. The Company recognizes the transaction price from annual contracts as a single performance obligation based on the proportion of transactions processed to the total estimated transactions to be processed over the contract period. Arrangements with Financial Institutions The Company enters into multi-year contracts with financial institution customers that typically include fees for initial implementation services that are paid during the period the implementation services are provided as well as fees for subscription and transaction processing services, which are subject to guaranteed monthly minimum fees that are paid monthly over the contract term. These contracts enable the financial institutions to provide their customers with access to online bill pay services through the financial institutions’ online platforms. Implementation services are required up-front up-front Remaining Performance Obligations with Financial Institutions As of June 30, 2019, the aggregate amount of transaction price allocated to performance obligations that are unsatisfied (or partially unsatisfied) was $34.0 million. Of this amount, the Company expects to recognize $8.7 million within one year and $25.3 million between one and five years. Deferred revenue Subscription and transaction fees from customers with which the Company has annual or multi-year contracts are generally billed in advance. These fees are initially recorded as deferred revenue and subsequently recognized as revenue as the performance obligation is satisfied. Deferred revenue is shown as current or non-current in the consolidated balance sheets. The current portion of the deferred revenue was $3.3 million and $3.5 million as of June 30, 2018 and 2019, respectively. The non-current portion of the deferred revenue was $1.9 million and $1.8 million as of June 30, 2018 and 2019, respectively. Fees for monthly subscription and transaction fees are billed in arrears on a monthly basis. During the year ended June 30, 2019, the Company recognized $3.4 million of revenue that was included in the deferred revenue balance as of June 30, 2018. Interest on Funds Held for Customers The Company also earns revenue from interest earned on funds held for customers that are initially deposited into the Company’s bank accounts that are separate from the Company’s operating cash accounts until remitted to the customers or their suppliers. The Company partially invests funds held for customers in highly liquid investments with maturities of three months or less and in marketable debt securities with maturities of three months to one year at the time of purchase. Interest and fees earned are recognized based on the effective interest method and also include the accretion of discounts and the amortization of premiums on marketable debt securities.

FAIR VALUE MEASUREMENT	Mar. 31, 2020	Jun. 30, 2019
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT	NOTE 3—FAIR VALUE MEASUREMENT The Company measures and reports its cash equivalents, short-term investments, funds held for customers that are invested in money market funds and marketable debt securities, and redeemable convertible preferred stock warrant liabilities at fair value. Fair value is defined as the exchange price that would be received for an asset or an exit price paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy defines a three-level valuation hierarchy for disclosure of fair value measurements as follows: Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities. Level 2—Inputs other than quoted prices included within Level 1 that are observable, unadjusted quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities. Level 3—Unobservable inputs that are supported by little or no market activity for the related assets or liabilities and typically reflect management’s estimate of assumptions that market participants would use in pricing the assets or liabilities. In determining fair value, the Company utilizes quoted market prices, or valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible, and also considers counterparty credit risk in its assessment of fair value. The following tables set forth the fair value of assets and liabilities that were measured at fair value on a recurring basis based on the three-tier fair value hierarchy as of the dates presented (in thousands): June 30, 2019 Level 1 Level 2 Level 3 Total Assets Cash equivalents: Money market funds $ 13,718 $ - $ - $ 13,718 13,718 - - 13,718 Short-term investments: U.S. treasury securities 64,758 - - 64,758 Corporate bonds - 4,787 - 4,787 Asset-backed securities - 2,424 - 2,424 64,758 7,211 - 71,969 Funds held for customers: Restricted cash equivalents 424,219 - - 424,219 Corporate bonds - 302,070 - 302,070 Certificates of deposit - 105,377 - 105,377 U.S. treasury securities 30,960 - - 30,960 455,179 407,447 - 862,626 Total assets measured at fair value $ 533,655 $ 414,658 $ - $ 948,313 Liabilities Redeemable convertible preferred stock warrant liabilities $ - $ - $ 688 $ 688 Total liabilities measured at fair value $ - $ - $ 688 $ 688 March 31, 2020 Level 1 Level 2 Level 3 Total Assets Cash equivalents: Money market funds $ 42,608 $ - $ - $ 42,608 Corporate bonds - 5,583 - 5,583 42,608 5,583 - 48,191 Short-term investments: U.S. treasury securities 28,373 - - 28,373 Corporate bonds - 99,492 - 99,492 Asset-backed securities - 25,973 - 25,973 28,373 125,465 - 153,838 Funds held for customers: Restricted cash equivalents 362,029 80,271 - 442,300 Corporate bonds - 469,071 - 469,071 Certificates of deposit - 78,714 - 78,714 U.S. treasury securities 19,419 - - 19,419 381,448 628,056 - 1,009,504 Total assets measured at fair value $ 452,429 $ 759,104 $ - $ 1,211,533 There were no transfers of financial instruments between Level 1, Level 2, and Level 3 during the periods presented.

The Company estimated the fair value of the liability using the Black-Scholes option-pricing model and any change in fair value is recognized as either gain or loss and included in other income, net in the accompanying condensed consolidated statements of operations. Immediately upon the completion of the Company’s IPO, all warrants to purchase shares of redeemable convertible preferred stock were converted into warrants to purchase shares of common stock.

The exercise price of non-statutory Stock option activity during the years ended June 30, 2018 and 2019 was as follows: Number of Weighted Weighted (in years) Aggregate Balance at June 30, 2017 4,554 $ 2.27 7.95 $ 8,230 Options granted 1,742 $ 4.17 Options exercised (341 ) $ 2.03 Options cancelled/forfeited/expired (339 ) $ 2.99 Balance at June 30, 2018 5,616 $ 2.83 7.75 $ 13,640 Options granted 5,706 $ 8.30 Options exercised (809 ) $ 2.10 Options cancelled/forfeited/expired (486 ) $ 4.92 Balance at June 30, 2019 10,027 $ 5.90 8.37 $ 75,223 Vested and expected to vest at June 30, 2019 (1) 8,670 $ 5.66 8.23 $ 67,129 Vested at June 30, 2019 3,241 $ 2.68 6.46 $ 34,755 (1) The expected-to-vest options are the result of applying the pre-vesting The total intrinsic value of options exercised during the years ended June 30, 2018 and 2019 was $0.7 million and $3.8 million, respectively. The intrinsic value was calculated as the difference between the estimated fair value of the Company’s common stock at exercise, as determined by the Board of Directors, and the exercise price of the in-the-money Stock-based compensation expense during the years ended June 30, 2018 and 2019 was included in the following line items in the accompanying consolidated statements of operations (in thousands): Year ended June 30, 2018 2019 Cost of revenue $ 78 $ 331 Research and development 429 1,128 Sales and marketing 508 922 General and administrative 530 1,701 $ 1,545 $ 4,082 As of June 30, 2019, there was $18.5 million of unamortized stock-based compensation cost related to unvested stock options which is expected to be recognized over a weighted-average period of 3.4 years. The Company received $0.7 million and $1.7 million from options exercised during the years ended June 30, 2018 and 2019, respectively. The fair value of options granted during the years ended June 30, 2018 and 2019 was estimated at the date of grant using the Black-Scholes option-pricing model with the following assumptions: Year ended June 30, 2018 2019 Expected term (in years) 6.25 6.25 Expected volatility 45.0% to 55.1 % 46.0% to 51.0 % Risk-free interest rate 2.05% to 2.89 % 2.19% to 2.89 % Expected dividend yield 0 % 0 % The fair value of the shares of common stock underlying stock options has historically been determined by the Company’s Board of Directors. Because there has been no public market for the Company’s common stock, the Board of Directors has determined fair value of the common stock at the time of grant of the option by considering a number of objective and subjective factors including important developments in the Company’s operations, valuations performed by an independent third party, sales of preferred stock, actual operating results and financial performance, the conditions in the industry and the economy in general, the stock price performance and volatility of comparable public companies, and the lack of liquidity of the Company’s common stock, among other factors. The Black-Scholes option-pricing model requires the use of highly subjective assumptions which determine the fair value of stock-based awards. These assumptions include: Expected term time-to-vesting Expected volatility Risk-free interest rate Expected dividend yield

Income Taxes	NOTE 10—INCOME TAXES The Company’s provision for (benefit from) income taxes during the interim periods is determined using an estimate of the Company’s annual effective tax rate, which is adjusted for certain discrete tax items during the interim period. The Company’s effective tax rate differs from the Federal statutory rate primarily due to the change in valuation allowance related mainly to the Company’s net operating loss carryforwards and research and development credits. The benefit from income taxes during the nine months ended March 31, 2019 pertains primarily to the income tax benefit that is reported on the condensed consolidated statements of operations and is offset against the income tax on the unrealized gain on investments in available-for-sale	NOTE 10—INCOME TAXES The components of loss before the provision for (benefit from) income taxes were as follows (in thousands): Year ended June 30, 2018 2019 Domestic $ (7,185 ) $ (7,470 ) Foreign - - Total $ (7,185 ) $ (7,470 ) The components of provision for (benefit from) income taxes were as follows (in thousands): Year ended June 30, 2018 2019 Current: Federal $ - $ - State 10 20 Foreign - Total current 10 20 Deferred: Federal - (142 ) State - (34 ) Foreign - - Total deferred - (176 ) Provision for (benefit from) income taxes $ 10 $ (156 ) On December 22, 2017, the 2017 Tax Cuts and Jobs Act (Tax Act) was enacted into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a federal corporate tax rate decrease from 35% to 21% for tax years beginning after December 31, 2017, the transition of U.S. international taxation from a worldwide tax system to a territorial system and a one-time re-measuring As of June 30, 2019, pursuant to SEC Staff Accounting Bulletin (SAB) 118 (regarding the application of ASC 740 associated with the enactment of the Tax Act) The items accounting for the difference between the income taxes computed at the federal statutory rate and the provision for (benefit from) income taxes consisted of the following (in thousands): Year ended June 30, 2018 2019 Expected benefit at U.S. Federal statutory rate $ (1,976 ) $ (1,569 ) Stock-based compensation 297 390 Federal and state R&D credits (909 ) (2,111 ) Deferred tax asset re-measurement 12,227 - Change in valuation allowance (9,753 ) 3,029 Other 124 105 Provision for income tax expense (benefit) $ 10 $ (156 ) The components of deferred tax assets and liabilities were as follows as of June 30, 2018 and 2019, (in thousands): June 30, 2018 2019 Deferred tax assets: Accruals and reserves $ 916 $ 1,631 Deferred revenue 33 84 Property and equipment 73 - Stock-based compensation 285 700 Net operating loss carryforwards 26,027 26,690 Research and development credits 3,056 5,649 Total deferred tax assets before valuation allowance 30,390 34,754 Valuation allowance (29,590 ) (33,253 ) Deferred tax assets $ 800 $ 1,501 Deferred tax liabilities: Deferred contract costs $ (800 ) $ (1,229 ) Property and equipment - (143 ) Other - (129 ) Total deferred tax liabilities $ (800 ) $ (1,501 ) Net deferred tax assets (liabilities) $ - $ - ASC 740 requires that the tax benefit of net operating losses, temporary differences, and credit carryforwards be recorded as an asset to the extent that management assesses that realization is “more likely than not.” Realization of the future tax benefits is dependent on the Company’s ability to generate sufficient taxable income within the carryforward period. Because of the Company’s recent history of operating losses, management believes that recognition of the deferred tax assets arising from the above-mentioned future tax benefits is currently not likely to be realized and, accordingly, has provided a valuation allowance. The change in valuation allowance was approximately $10.0 million and $3.7 million during the years ended June 30, 2018 and 2019, respectively, including a decrease in valuation allowance of $0.7 million related to the adoption of ASC 606 during the year ended June 30, 2018. As of June 30, 2019, the Company had net operating loss carryforwards for federal and state tax purposes of $104.2 million and $71.3 million respectively, available to reduce future taxable income. If not utilized, the federal and state net operating loss carryforwards will begin to expire in 2026. As of June 30, 2019, the Company also has federal and state research and development tax credit carryforwards of $4.7 million and $4.3 million, respectively. If not utilized, the federal tax credits will expire at various dates beginning in 2027. The state tax credits do not expire and will carry forward indefinitely until utilized. Utilization of the net operating loss and tax credit carryforwards may be subject to a substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code and other similar state provisions. The annual limitation may result in the expiration of net operating losses and tax credits before utilization. As of June 30, 2018 and 2019, the Company had $1.5 million and $2.7 million, respectively, of unrecognized tax benefits related to federal and California R&D credits. Below is the reconciliation of the unrecognized tax benefits (in thousands): June 30, 2018 2019 Balance at the beginning of the year $ 835 $ 1,457 Additions based upon tax positions related to the current year - 1,028 Additions based upon tax positions related to the prior year 622 207 Balance at the end of the year $ 1,457 $ 2,692 The Company files United States federal, California, and other various state income tax returns.

Each offering period is comprised of two six-month 12-month th 6-month th th The fair value of ESPP offerings during the nine months ended March 31, 2020 was estimated at the date of each offering using the Black-Scholes option-pricing model with the following assumptions: (i) expected term range of 0.5 year to 1.17 years, (ii) expected volatility of 50%, (iii) risk-free interest rate range of 1.47% to 1.56% and (iv) expected dividend yield of 0%. As of March 31, 2020, the total unrecognized compensation expense related to the ESPP was $2.9 million, which is expected to be amortized over the next 12 months.

Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and have been prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) and applicable rules and regulations of the Securities and Exchange Commission (SEC) regarding interim financial reporting. The unaudited condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and reflect all normal and recurring adjustments that are, in the opinion of management, necessary to present fairly the Company’s financial position, results of operations, comprehensive loss, changes in redeemable convertible preferred stock and stockholders’ equity (deficit), and cash flows for the periods presented. The results of operations for the three and nine months ended March 31, 2020 are not necessarily indicative of the results to be expected for the year ending June 30, 2020 or for any other future annual or interim period. The unaudited condensed consolidated balance sheet as of June 30, 2019 included herein was derived from the audited financial statements as of that date, but does not include all disclosures including certain notes required by U.S. GAAP on an annual reporting basis. All significant intercompany accounts and transactions have been eliminated. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s final prospectus filed with the SEC pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended, on December 12, 2019 (Prospectus).

Segment Reporting	Segment Reporting The Company operates as one operating segment because its chief operating decision maker, who is the Chief Executive Officer, reviews its financial information on a consolidated basis for purposes of making decisions regarding allocating resources and assessing performance. All long-lived assets are located in the United States and all revenue is generated in the United States.	Segment Reporting
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make various estimates and assumptions that affect the amounts reported and disclosed in the condensed consolidated financial statements and the accompanying notes. Management regularly assesses these estimates, including those related to fair value of common stock prior to the Company’s IPO and stock-based compensation, fair value of redeemable convertible preferred stock warrant liabilities up until the date of the Company’s IPO, useful lives of property and equipment, the attribution method used to recognize revenue on annual contracts, reserve for sales tax obligations, reserve for losses on funds held for customers, and income taxes. The Company evaluates these estimates and assumptions and adjusts those estimates and assumptions accordingly. Actual results could differ from those estimates, and such differences may be material to the condensed consolidated financial statements.	Use of Estimates

These contracts are either cancelable arrangements paid monthly in arrears that can be terminated by either party without a penalty at any time or non-cancelable The Company’s contracts with SMB and accounting firm customers are generally comprised of a single performance obligation to provide access to the functionality of the Company’s platform to process transactions. The Company accounts for open-ended cancelable contracts as a daily service. Subscription revenue for such contracts is recognized ratably over the period that the customers have access to the platform. Transaction revenue is recognized on the date the transactions are processed by the Company. The Company accounts for its annual and monthly contracts as a series of distinct services satisfied over time. The Company determines the transaction price for such contracts by estimating the total consideration to be received over the contract term from subscription and transaction fees. The Company recognizes the transaction price from annual contracts as a single performance obligation based on the proportion of transactions processed to the total estimated transactions to be processed over the contract period. Arrangements with Financial Institutions The Company enters into multi-year contracts with financial institution customers that typically include fees for initial implementation services that are paid during the period the implementation services are provided as well as fees for subscription and transaction processing services, which are subject to guaranteed monthly minimum fees that are paid monthly over the contract term. These contracts enable the financial institutions to provide their customers with access to online bill pay services through the financial institutions’ online platforms. Implementation services are required up-front up-front Remaining Performance Obligations with Financial Institutions As of June 30, 2019, the aggregate amount of transaction price allocated to performance obligations that are unsatisfied (or partially unsatisfied) was $34.0 million. Of this amount, the Company expects to recognize $8.7 million within one year and $25.3 million between one and five years. Deferred revenue Subscription and transaction fees from customers with which the Company has annual or multi-year contracts are generally billed in advance. These fees are initially recorded as deferred revenue and subsequently recognized as revenue as the performance obligation is satisfied. Deferred revenue is shown as current or non-current in the consolidated balance sheets. The current portion of the deferred revenue was $3.3 million and $3.5 million as of June 30, 2018 and 2019, respectively. The non-current portion of the deferred revenue was $1.9 million and $1.8 million as of June 30, 2018 and 2019, respectively. Fees for monthly subscription and transaction fees are billed in arrears on a monthly basis. During the year ended June 30, 2019, the Company recognized $3.4 million of revenue that was included in the deferred revenue balance as of June 30, 2018. Interest on Funds Held for Customers The Company also earns revenue from interest earned on funds held for customers that are initially deposited into the Company’s bank accounts that are separate from the Company’s operating cash accounts until remitted to the customers or their suppliers. The Company partially invests funds held for customers in highly liquid investments with maturities of three months or less and in marketable debt securities with maturities of three months to one year at the time of purchase. Interest and fees earned are recognized based on the effective interest method and also include the accretion of discounts and the amortization of premiums on marketable debt securities.

Emerging Growth Company Status	Emerging Growth Company Status The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the JOBS Act). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it is (i) no longer an emerging growth company or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these condensed consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. The JOBS Act does not preclude an emerging growth company from early adopting new or revised accounting standards. The Company expects to use the extended transition period for any new or revised accounting standards during the period which the Company remains an emerging growth company.
