G-Invoicing

G-Invoicing

G-Invoicing is the long-term solution for Federal Program Agencies (FPAs) to manage their intragovernmental (IGT) Buy/Sell transactions. G‑Invoicing helps (or will help) agencies and their trading partners:

  • Negotiate and accept General Terms and Conditions (GT&C) agreements
  • Broker orders
  • Exchange performance information
  • Validate settlement requests through IPAC

FPAs must implement G-Invoicing for New Orders by October 2022. The mandated implementation deadline of October 2022 for New Orders includes Orders with a Period of Performance beginning October 1, 2022 or later.

FPAs must submit quarterly implementation status updates to Treasury by providing updated plans and/or Attachment As to the IGT mailbox (IGT@fiscal.treasury.gov).

Treasury will help agencies get ready for and start using G-Invoicing. (See more on the Enrollment page.)

Benefits of G-Invoicing

Better communication between trading partners: Using G Invoicing to communicate, trading partners share a common platform and a clear record of their negotiations.

Transparency: G-Invoicing supports each phase of the IGT buy/sell lifecycle. This common repository will decrease differences between agencies.

Common data standard: G-Invoicing replaces the various terms and forms that agencies now use. Standard terms reduce misunderstandings.

Agreed-upon processes: Common processes support timely and accurate accounting.

Streamlined settlements of funds in IPAC: With performance reporting in G-Invoicing, trading partners can settle more quickly and efficiently.
