American Express has launched a new digital payment service that provides corporations with something that banks to date have not been able to offer—a consolidated offering that supports check, ACH, wire and credit card payments.

Companies using the new service, Payve, send a file to American Express that can include instructions for multiple vendors and various payment methods. American Express directs the payments to each supplier using the designated method, and Payve processes the payments to clients' banks, allowing companies to maintain their existing banking relationships and corporate processes.

In addition, an American Express team will help clients add suppliers and support their transition to electronic payments, says Andrew Jamison, vice president of global corporate payments.
