It is listed on Nasdaq as ACIW and is based in Elkhorn, Nebraska, according to its FY2025 annual report. The filing says it serves thousands of organizations in about 90 countries, including nearly all of the ten largest banks and more than 80,000 merchants, and had 2,930 employees at 31 December 2025.
The company's website says it was incorporated in Omaha, Nebraska, in 1975 with five employees. The annual report says the current company was incorporated in 1993 as ACI Holding, Inc., largely as successor to Applied Communications, Inc., and was renamed from Transaction Systems Architects in July 2007. Thomas W. Warsop III has been president and chief executive since 1 June 2023, and Robert W. Leibrock became chief financial officer on 1 July 2025.
ACI reports two segments, Payment Software and Billers. Its solution areas are issuing and acquiring, account-to-account real-time payments, merchant payments on the ACI Payments Orchestration Platform, payments intelligence and risk management, and bill payments through ACI Speedpay. It launched ACI Connetic, a payments hub, in 2025.
ACI bought Speedpay in 2019, which its website calls its largest acquisition to date. On 3 November 2025 it announced the acquisition of Payment Components, a Greek provider of financial messaging and open banking software founded in 2014 and used by 65 banks and institutions in 25 countries. Financial terms were not disclosed.

The filing says ACI has customers in the Middle East, and MEA Finance named it Most Innovative Payment Solutions Provider in 2026, according to the website.
In September 2026 ACI announced that the Federal Home Loan Bank of Cincinnati was moving member payment processing to ACI Connetic and that Solaris had gone live on it for SEPA Instant payments.
