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 were prepared in conformity with U.S. generally accepted accounting principles (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 state fairly the Company’s financial position, results of operations, comprehensive loss, changes in stockholders’ equity, and cash flows for the periods presented. The results of operations for the three months ended September 30, 2023 are not necessarily indicative of the results to be expected for the fiscal year ending June 30, 2024 or for any other future annual or interim period. The unaudited condensed consolidated balance sheet as of June 30, 2023 included herein was derived from the audited financial statements as of that date, but does not include all disclosures including certain notes required by GAAP on an annual reporting basis. All 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 Annual Report on Form 10-K for the fiscal year ended June 30, 2023.
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. The Company's long-lived assets are mainly located in the United States (U.S.) and revenue is mainly generated in the U.S. Long-lived assets outside the U.S. are not material as of September 30, 2023 and June 30, 2023. Total revenue from external customers outside of the U.S. was approximately 3% of consolidated total revenue during each of the three months ended September 30, 2023 and 2022.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with 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, but not limited to useful lives of long-lived assets; capitalization of internal-use software costs; incremental borrowing rates for right-of-use operating lease assets and operating lease liabilities; the estimate of losses on accounts receivable, acquired card receivables and other financial assets; accrual for rewards; variable consideration used in revenue recognition for certain contracts; benefit periods used to amortize deferred costs; reserve for losses on funds held for customers; inputs used to value certain stock-based compensation awards; and valuation of deferred tax assets. The Company evaluates these estimates and assumptions and adjusts them accordingly. Actual results could differ from those estimates, and such differences may be material to the condensed consolidated financial statements.
Cash, Cash Equivalents, Restricted Cash and Restricted Cash Equivalents	Cash, Cash Equivalents, Restricted Cash and Restricted Cash Equivalents Cash and cash equivalents consist of cash in banks, highly liquid investments with maturities of three months or less at the time of purchase. Restricted cash consists of (i) amounts restricted under deposit account control agreements, (ii) minimum cash balances that are required to be maintained by certain banks, (iii) cash collateral required by the Company’s lessors to satisfy letter of credit requirements under its lease agreements, (iv) cash collateral required by a bank in connection with the Company’s money transmission activities, and (v) cash in bank and cash deposits held by payment processing companies included in funds held for customers. Restricted cash equivalents consist of highly liquid investments with maturities of three months or less at the time of purchase that are included in funds held for customers. Except for the restricted cash included in funds held for customers, the current and non-current portion of the restricted cash is included in prepaid expenses and other current assets and in other assets, respectively, in the accompanying condensed consolidated balance sheets.
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash, cash equivalents, restricted cash, restricted cash equivalents, short-term investments, accounts receivable, and acquired card receivables (collectively referred to as Financial Assets). The Company maintains its cash, cash equivalents, restricted cash, restricted cash equivalents and short-term investments with large multinational financial institutions that may at times exceed federally insured limits. In connection with recent instability in the U.S. banking system, the Company's management has taken incremental precautions to safeguard its assets and evaluate the nature and extent of its financial partnerships. Management believes that the financial institutions with which the Company does business are financially sound with minimal credit risk. Management further believes the associated risk of concentration for the Company’s investments is mitigated by holding a diversified portfolio of highly rated investments consisting of money market funds and short-term debt securities.
Foreign Currency	Foreign CurrencyThe functional currency of the Company's foreign subsidiaries is the U.S. dollar, which is the Company's reporting currency. Gains and losses from the remeasurement of transactions denominated in foreign currencies other than the functional currency of the foreign subsidiaries are included in other income, net in the accompanying condensed consolidated statements of operations

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 contingent consideration 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. Our financial instruments not measured and recorded at fair value, includes cash, restricted cash, acquired cards receivables, interest receivable, incentive receivables and borrowings from revolving credit facility, are carried at amortized cost, which approximates their fair value. If these financial instruments were measured at fair value in the financial statements, cash would be classified as Level 1; restricted cash, interest receivables, incentive receivables and borrowings from revolving credit facility would be classified as Level 2 and the acquired cards receivables would be classified as Level 3 in the fair value hierarchy.
