Electronic Data Interchange

This is GSA Global Supply’s preferred method for conducting business transactions. It is a fully automated process that entails a per transaction cost. Electronic Data Interchange (EDI) provides for full electronic processing of all ordering transactions. It is restricted to high volume Vendors with at least 100 purchase orders per month.

*GSA does not endorse any third-party EDI Vendors.

GSA utilizes the American National Standards Institute (ANSI) X-12 family of transaction sets to electronically communicate both “Inbound” and “Outbound” transaction sets. GSA Global Supply has partnered with IBM to develop and operate an EDI Gateway for Purchase Order (PO) creation and management services. Vendors must follow a standardized onboarding process to set up a connection to the EDI gateway.

Onboarding Process

Vendors must be current GSA Global Supply contract holders. The expectations for the vendors are as follows:

  • Contact GSAEDI@gsa.gov to start the process.
  • Complete the EDI onboarding survey to determine specific EDI capabilities.
  • Attend an EDI kickoff meeting to exchange connection information and review EDI requirements.
  • Actively engage in the testing process:
    • Provide a test catalog to generate test transactions that need to be received, acknowledged and processed.
    • Respond in a timely manner to questions and requests for information.

The testing process concludes with GSA Global Supply validating the transactions received from the vendor and providing approval to be a certified GSA Global Supply EDI vendor. At that point, the vendor can start conducting business with GSA Global Supply using EDI.
