EDI and Vendor Portal

GSA Global Supply mandates that industry partners use one of the following business transaction processing methods:

Electronic Data Interchange (EDI)

This is GSA Global Supply’s preferred method for conducting business transactions. EDI provides for fully electronic processing of all ordering transactions. GSA utilizes the American National Standards Institute (ANSI) X-12 family of transaction sets to electronically communicate both “Inbound” and “Outbound” transaction sets.

Vendor Portal (VP)

An online tool that gives industry partners who are not using EDI better visibility into their orders and enables automatic communications between GSA and its customers. While EDI remains the preferred processing method, industry partners with small order volume and less technical proficiency may choose to use Vendor Portal.
