Organization, Consolidation and Presentation of Financial Statements [Abstract]
Condensed Consolidated Financial Statements	Condensed Consolidated Financial Statements The unaudited condensed consolidated financial statements include the accounts of ACI Worldwide, Inc. and its wholly-owned subsidiaries (collectively, the “Company”). All intercompany balances and transactions have been eliminated. The condensed consolidated financial statements as of September 30, 2024, and for the three and nine months ended September 30, 2024 and 2023, are unaudited and reflect all adjustments of a normal recurring nature, which are, in the opinion of management, necessary for a fair presentation, in all material respects, of the financial position and operating results for the interim periods. The condensed consolidated balance sheet as of December 31, 2023, is derived from the audited financial statements. The condensed consolidated financial statements contained herein should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2023, filed on February 29, 2024. Results for the three and nine months ended September 30, 2024, are not necessarily indicative of results that may be attained in the future. The preparation of condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make judgments, estimates, and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions are affected by management’s application of accounting policies, as well as uncertainty in the current economic environment. Actual results could differ from those estimates. Other Current Liabilities The components of other current liabilities are included in the following table (in thousands): September 30, 2024 December 31, 2023 Operating lease liabilities $ 8,960 $ 9,348 Vendor financed licenses 8,076 12,702 Accrued interest 3,124 9,172 Other 54,876 51,022 Total other current liabilities $ 75,036 $ 82,244 Settlement Assets and Liabilities Individuals and businesses settle their obligations to the Company’s various Biller clients using credit or debit cards or via automated clearing house (“ACH”) payments. The Company creates a receivable for the amount due from the credit or debit card processor and an offsetting payable to the client. Upon confirmation that the funds have been received, the Company settles the obligation to the client. Due to timing, in some instances, the Company may (1) receive the funds into bank accounts controlled by and in the Company’s name that are not disbursed to its clients by the end of the day, resulting in a settlement deposit on the Company’s books and (2) disburse funds to its clients in advance of receiving funds from the credit or debit card processor, resulting in a net settlement receivable position. Off Balance Sheet Settlement Accounts The Company also enters into agreements with certain Biller clients to process payment funds on their behalf. When an ACH or automated teller machine network payment transaction is processed, a transaction is initiated to withdraw funds from the designated source account and deposit them into a settlement account, which is a trust account maintained for the benefit of the Company’s clients. A simultaneous transaction is initiated to transfer funds from the settlement account to the intended destination account. These “back to back” transactions are designed to settle at the same time, usually overnight, such that the Company receives the funds from the source at the same time as it sends the funds to their destination. However, due to the transactions being with various financial institutions there may be timing differences that result in float balances. These funds are maintained in accounts for the benefit of the client which is separate from the Company’s corporate assets. As the Company does not take ownership of the funds, these settlement accounts are not included in the Company’s balance sheet. The Company is entitled to interest earned on the fund balances. The collection of interest on these settlement accounts is considered in the Company’s determination of its fee structure for clients and represents a portion of the payment for services performed by the Company. The amount of settlement funds as of September 30, 2024, and December 31, 2023, was $315.5 million and $273.2 million, respectively. Fair Value The fair value of the Company’s Credit Agreement approximates the carrying value due to the floating interest rate (Level 2 of the fair value hierarchy). The Company measures the fair value of its Senior Notes based on Level 2 inputs, which include quoted market prices and interest rate spreads of similar securities. The fair value of the Company’s 5.750% Senior Notes due 2026 (“2026 Notes”) was $399.6 million and $398.5 million as of September 30, 2024, and December 31, 2023, respectively. The fair values of cash and cash equivalents approximate the carrying values due to the short period of time to maturity (Level 2 of the fair value hierarchy). Goodwill In accordance with the Accounting Standards Codification ("ASC") 350, Intangibles – Goodwill and Other , the Company assesses goodwill for impairment annually during the fourth quarter of its fiscal year using October 1 balances or when there is evidence that events or changes in circumstances indicate that the carrying amount of the asset may not be recovered. The Company evaluates goodwill at the reporting unit level and has identified its operating segments, Banks, Merchants, and Billers, as the reporting units. As of September 30, 2024, the Company's goodwill balance of $1.2 billion was allocated $671.7 million to Banks, $137.3 million to Merchants, and $417.0 million to Billers. Recoverability of goodwill is measured using a discounted cash flow model incorporating discount rates commensurate with the risks involved. Use of a discounted cash flow model is common practice in impairment testing in the absence of available transactional market evidence to determine the fair value. The calculated fair value was substantially in excess of the current carrying value for all reporting units based upon the October 1, 2023, annual impairment test and there have been no indications of impairment in the subsequent periods. Equity Method Investment In July 2019, the Company invested $18.3 million for a 30% non-controlling financial interest in a payment technology and services company in India. The Company accounted for this investment using the equity method in accordance with ASC 323, Investments - Equity Method and Joint Ventures . The Company records its share of earnings and losses in the investment on a one-quarter lag basis. Accordingly, the Company recorded an investment of $19.6 million and $18.5 million, which is included in other noncurrent assets in the condensed consolidated balance sheet as of September 30, 2024, and December 31, 2023, respectively. Recently Issued Accounting Standards Not Yet Effective In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures , to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective for annual periods beginning after December 15, 2023 and interim periods beginning after December 15, 2024, and early application is permitted. The Company is currently assessing the impact the adoption of ASU 2023-07 will have on its segment reporting disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures , to enhance the transparency and decision usefulness of income tax disclosures. The amendments in this update will require disclosure of more disaggregated information about a reporting entity's effective tax rate reconciliation and income taxes paid. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, and early application is permitted for annual financial statements that have not yet been issued or made available for issuance. The Company is currently assessing the impact the adoption of ASU 2023-09 will have on its income tax disclosures.

Revenue from Contract with Customer [Abstract]
Revenue	Revenue In accordance with ASC 606, Revenue From Contracts With Customers , revenue is recognized upon transfer of control of promised products and/or services to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those products and services. Revenue is recognized net of any taxes collected from customers and subsequently remitted to governmental authorities. See Note 9, Segment Information, for additional information, including disaggregation of revenue based on primary solution category. Total receivables represent amounts billed and amounts earned that are to be billed in the future (i.e., accrued receivables). Included in accrued receivables are services, software as a service ("SaaS"), and platform as a service ("PaaS") revenues earned in the current period but billed in the following period, and amounts due under multi-year software license arrangements with extended payment terms for which the Company has an unconditional right to invoice and receive payment subsequent to invoicing. Total receivables, net is comprised of the following (in thousands): September 30, 2024 December 31, 2023 Billed receivables $ 201,577 $ 250,423 Allowance for credit losses (1,936) (4,295) Billed receivables, net 199,641 246,128 Current accrued receivables, net 224,877 206,209 Long-term accrued receivables, net 338,977 313,983 Total accrued receivables, net 563,854 520,192 Total receivables, net $ 763,495 $ 766,320 No customer accounted for more than 10% of the Company’s consolidated receivables balance as of September 30, 2024 and December 31, 2023. Deferred revenue includes amounts due or received from customers for software licenses, maintenance, services, and/or SaaS and PaaS services in advance of recording the related revenue. Changes in deferred revenue were as follows (in thousands): Balance, December 31, 2023 $ 84,360 Deferral of revenue 95,861 Recognition of deferred revenue (93,900) Foreign currency translation 1,544 Balance, September 30, 2024 $ 87,865 Revenue allocated to remaining performance obligations represents contracted revenue that will be recognized in future periods, which is comprised of deferred revenue and amounts that will be invoiced and recognized as revenue in future periods. This does not include: • Revenue that will be recognized in future periods from capacity overages that are accounted for as a usage-based royalty. • SaaS and PaaS revenue from variable consideration that will be recognized in accordance with the ‘right to invoice’ practical expedient or meets the allocation objective. Revenue allocated to remaining performance obligations was $659.2 million as of September 30, 2024, of which the Company expects to recognize approximately 51% over the next 12 months and the remainder thereafter. During the three and nine months ended September 30, 2024, revenue recognized by the Company from performance obligations satisfied in previous periods was not significant. During the three and nine months ended September 30, 2023, revenue recognized by the Company from performance obligations satisfied in previous periods was $23.3 million and $43.7 million, respectively.

Earnings Per Share [Abstract]
Earnings (Loss) Per Share	Earnings (Loss) Per Share Basic earnings (loss) per share is computed in accordance with ASC 260, Earnings Per Share , based on weighted average outstanding common shares. Diluted earnings (loss) per share is computed based on basic weighted average outstanding common shares adjusted for the dilutive effect of stock options, RSUs, and certain contingently issuable shares for which performance targets have been achieved. The following table reconciles the weighted average share amounts used to compute both basic and diluted earnings (loss) per share (in thousands): Three Months Ended Nine Months Ended 2024 2023 2024 2023 Weighted average shares outstanding: Basic weighted average shares outstanding 104,770 108,667 105,651 108,428 Add: Dilutive effect of stock options and RSUs 1,248 266 901 — Diluted weighted average shares outstanding 106,018 108,933 106,552 108,428 The diluted earnings (loss) per share computation excludes 1.0 million and 2.0 million options to purchase shares, RSUs, and contingently issuable shares during the three months ended September 30, 2024 and 2023, respectively, as their effect would be anti-dilutive. The diluted earnings (loss) per share computation excludes 1.2 million and 3.2 million options to purchase shares, RSUs, and contingently issuable shares during the nine months ended September 30, 2024 and 2023, respectively, as their effect would be anti-dilutive.

Segment Reporting [Abstract]
Segment Information	Segment Information The Company reports financial performance based on its operating segments, Banks, Merchants, and Billers, and analyzes Segment Adjusted EBITDA as a measure of segment profitability. The Company’s Chief Executive Officer is also the chief operating decision maker ("CODM"). The CODM, together with other senior management personnel, focus their review on consolidated financial information and the allocation of resources based on operating results, including revenues and Segment Adjusted EBITDA, for each segment, separate from corporate operations. No operating segments have been aggregated to form the reportable segments. Banks. ACI provides payment solutions to large and mid-size banks globally for retail banking, real time, digital, and other payment services. These solutions transform banks’ complex payment environments to speed time to market, reduce costs, and deliver a consistent experience to customers across channels while enabling them to prevent and rapidly react to fraudulent activity. In addition, they enable banks to meet the requirements of different real-time payments schemes and to quickly create differentiated products to meet consumer, business, and merchant demands. Merchants. ACI’s support of merchants globally includes Tier 1 and Tier 2 merchants, online-only merchants and the payment service providers, independent selling organizations, value-added resellers, and acquirers who service them. These customers operate in a variety of verticals, including general merchandise, grocery, hospitality, dining, transportation, and others. The Company's solutions provide merchants with a secure, omni-channel payments platform that gives them independence from third-party payment providers. They also offer secure solutions to online-only merchants that provide consumers with a convenient and seamless way to shop. Billers. Within the billers segment, ACI provides electronic bill presentment and payment (“EBPP”) services to companies operating in the consumer finance, insurance, healthcare, higher education, utility, government, and mortgage categories. The solutions enable these customers to support a wide range of payment options and provide a convenient consumer payments experience that drives consumer loyalty and increases revenue. Revenue is attributed to the reportable segments based upon customer. Expenses are attributed to the reportable segments in one of three methods: (1) direct costs of the segment, (2) labor costs that can be attributed based upon time tracking for individual projects, or (3) costs that are allocated. Allocated costs are generally marketing and sales related activities. Segment Adjusted EBITDA is the measure reported to the CODM for purposes of making decisions on allocating resources and assessing the performance of the Company’s segments, and, therefore, Segment Adjusted EBITDA is presented in conformity with ASC 280, Segment Reporting. Segment Adjusted EBITDA is defined as earnings (loss) from operations before interest, income tax expense (benefit), depreciation and amortization (“EBITDA”) adjusted to exclude net other income (expense). Corporate and unallocated expenses includes global facilities and information technology costs and long-term product roadmap expenses in addition to corporate overhead costs that are not allocated to reportable segments. The overhead costs relate to human resources, finance, legal, accounting, and merger and acquisition activity. These costs along with depreciation and amortization and stock-based compensation are not considered when management evaluates segment performance.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three and nine months ended September 30, 2024, the Company's effective tax rate was 24% and 25%, respectively. The Company reported a tax charge on pretax income for both the three and nine months ended September 30, 2024, with foreign entities recognizing earnings of $107.6 million and $148.1 million, respectively. For the three and nine months ended September 30, 2023, the Company's effective tax rate was 19% and 83%, respectively. The Company reported a tax charge on pretax income for the three months ended September 30, 2023 and a tax benefit on pretax loss for the nine months ended September 30, 2023, with foreign entities recognizing earnings of $47.9 million and $64.9 million, respectively. The Company’s effective tax rate could fluctuate on a quarterly basis due to the occurrence of significant and unusual or infrequent items, such as vesting of stock-based compensation or foreign currency gains and losses. The Company’s effective tax rate could also fluctuate due to changes in the valuation of its deferred tax assets or liabilities, or by changes in tax laws, regulations, accounting principles, or interpretations thereof. In addition, the Company is occasionally subject to examination of its income tax returns by tax authorities in the jurisdictions it operates. The Company regularly assesses the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of its provision for income taxes. The Organization for Economic Co-operation and Development Inclusive Framework on Base Erosion and Profit Shifting released Pillar Two Model Rules (“Pillar Two”) for a global minimum tax. Many countries have enacted certain aspects of the Pillar Two framework with effective dates in 2024. Entities operating in countries where Pillar Two has been enacted are required to estimate Pillar Two top-up tax obligations beginning in the first quarter of 2024. For the nine months ended September 30, 2024, the Company did not have material Pillar Two top-up tax obligations impacting the Company’s estimated annual effective tax rate. The Company will continue to evaluate the impact of proposed and enacted legislation as new guidance becomes available. As of September 30, 2024, and December 31, 2023, the amount of unrecognized tax benefits for uncertain tax positions was $21.0 million and $20.9 million, respectively, excluding related liabilities for interest and penalties of $0.4 million and $0.5 million, respectively. The Company believes it is reasonably possible that the total amount of unrecognized tax benefits will decrease within the next 12 months by approximately $2.3 million, due to the settlement of various audits and the expiration of statutes of limitation.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation	The unaudited condensed consolidated financial statements include the accounts of ACI Worldwide, Inc. and its wholly-owned subsidiaries (collectively, the “Company”). All intercompany balances and transactions have been eliminated. The condensed consolidated financial statements as of September 30, 2024, and for the three and nine months ended September 30, 2024 and 2023, are unaudited and reflect all adjustments of a normal recurring nature, which are, in the opinion of management, necessary for a fair presentation, in all material respects, of the financial position and operating results for the interim periods. The condensed consolidated balance sheet as of December 31, 2023, is derived from the audited financial statements. The condensed consolidated financial statements contained herein should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2023, filed on February 29, 2024. Results for the three and nine months ended September 30, 2024, are not necessarily indicative of results that may be attained in the future.
Use of Estimates	The preparation of condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make judgments, estimates, and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions are affected by management’s application of accounting policies, as well as uncertainty in the current economic environment. Actual results could differ from those estimates.
Settlement Assets and Liabilities	Settlement Assets and Liabilities Individuals and businesses settle their obligations to the Company’s various Biller clients using credit or debit cards or via automated clearing house (“ACH”) payments. The Company creates a receivable for the amount due from the credit or debit card processor and an offsetting payable to the client. Upon confirmation that the funds have been received, the Company settles the obligation to the client. Due to timing, in some instances, the Company may (1) receive the funds into bank accounts controlled by and in the Company’s name that are not disbursed to its clients by the end of the day, resulting in a settlement deposit on the Company’s books and (2) disburse funds to its clients in advance of receiving funds from the credit or debit card processor, resulting in a net settlement receivable position.

Fair Value	Fair Value
Goodwill	Goodwill In accordance with the Accounting Standards Codification ("ASC") 350, Intangibles – Goodwill and Other Recoverability of goodwill is measured using a discounted cash flow model incorporating discount rates commensurate with the risks involved. Use of a discounted cash flow model is common practice in impairment testing in the absence of available transactional market evidence to determine the fair value. The calculated fair value was substantially in excess of the current carrying value for all reporting units based upon the October 1, 2023, annual impairment test and there have been no indications of impairment in the subsequent periods.
Equity Method Investment	Equity Method Investment In July 2019, the Company invested $18.3 million for a 30% non-controlling financial interest in a payment technology and services company in India. The Company accounted for this investment using the equity method in accordance with ASC 323, Investments - Equity Method and Joint Ventures . The Company records its share of earnings and losses in the investment on a one-quarter lag basis. Accordingly, the Company recorded an investment of $19.6 million and $18.5 million, which is included in other noncurrent assets in the condensed consolidated balance sheet as of September 30, 2024, and December 31, 2023, respectively.
Recently Issued Accounting Standards Not Yet Effective	Recently Issued Accounting Standards Not Yet Effective In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures , to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective for annual periods beginning after December 15, 2023 and interim periods beginning after December 15, 2024, and early application is permitted. The Company is currently assessing the impact the adoption of ASU 2023-07 will have on its segment reporting disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures , to enhance the transparency and decision usefulness of income tax disclosures. The amendments in this update will require disclosure of more disaggregated information about a reporting entity's effective tax rate reconciliation and income taxes paid. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, and early application is permitted for annual financial statements that have not yet been issued or made available for issuance.
