(Omaha, Neb. – 16 April 2007) – ACI Worldwide (NASDAQ: TSAI), a leading international provider of software for electronic payment systems, today announced its strategy for leveraging the recently acquired trade finance and cash management solutions of Visual Web Solutions, Inc. The acquisition allows ACI to expand its global cash management capabilities with multi-language and multi-currency support, while offering an end-to-end trade finance solution for both traditional and open account trading.

Visual Web’s market-ready trade services are an ideal complement to ACI’s robust wholesale banking and payments suite.  Through the acquisition, ACI now offers a single product for end-to-end trade finance that provides back-end trade processing for bank operations as well as an integrated front-end open account trading vehicle for bank and customer use.  The solution is fully compliant with the SWIFT Trade Services Utility (TSU) and supports standard purchase order formats between buyer and seller.  The solution is built using a modern service-oriented architecture, offers integrated payment processing, and supports the integration of buyer/seller financing with bank accounting systems.
