Electronic Invoicing

Vendor Electronic Invoicing

GSA has several applications to support various needs of our vendors for electronic invoicing. GSA prefers electronic invoicing. Some reasons to consider electronic invoicing are because it:

• Is a paperless process
• Increases invoicing visibility and control
• Reduces invoice payment cycle times
• Minimizes invoice returns
• Reduces postage and paper costs
• Sustains the environment

The electronic option will differ based upon the GSA provided acquisition reference number known as the Pegasys Document Number (PDN), Purchase Order (PO) number or Accounting Control Transaction (ACT) number. If the PDN/PO/ACT number is unknown, please contact your GSA Contracting Officer for assistance.
