XIGN ON WEDNESDAY made available its Enterprise Adapter for SAP, which integrates Xign’s electronic invoice and payment platform with SAP R/3 enterprise resource management systems. Xign’s platform, XPSN (Xign Payment Services Network), connects SAP R/3 customers to an Internet-based network for accounts payable. The subscription-based network for buyers and suppliers automates such functions as invoice receipt, validation, routing, dispute management, approval, and payment, according to Xign officials in Pleasanton, Calif. This electronic method cuts both time and cost from the accounts payable process, traditional paper-based methods. Xign adapters support an open interface architecture to integrate with an array of accounting applications, including those from PeopleSoft and Oracle. Software Development
