DOI's G-Invoicing Implementation Plan

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 implement G-Invoicing for "In-Flight" Orders by October 2023. The mandated implementation deadline of October 2023 for "In-Flight" Orders includes the conversion of Orders with an open balance and a Period of Performance extending beyond September 30, 2023.

DOI Implementation Status Update

DOI is working diligently with our Enterprise Resource Planning (ERP) vendor to implement Treasury's G-Invoicing mandate.  DOI Bureaus and Office will continue to work with our trading partners on finalizing requirements but will be unable to fully approve agreements until we receive a minimally viable product from our ERP vendor.  DOI's updated implementation plan is to go-live in G-Invoicing for all new orders in October 2024 in conjunction with our deployment of S4 HANA.  At this time, no decision is being made on whether we will convert inflight orders into G-Invoicing.
