Government-wide G-Invoicing Implementation

As you are aware, there is a government-wide effort under way to implement G-Invoicing. G-Invoicing is an online solution, managed by the U.S. Department of Treasury, Bureau of Fiscal Service, to provide a common platform for intragovernmental transactions. G-Invoicing addresses accounting and reporting challenges around buy and sell transactions.

All federal program agencies must implement G-Invoicing for new orders by October 1, 2022. The implementation deadline for “in-flight” orders is October 1, 2023.

G-Invoicing will:

  • Create and store interagency agreements
  • Create orders
  • Track performance against orders
  • Transfer funds

In an effort to move all of our existing and new intragovernmental transactions to G-Invoicing, IBC is beginning to engage in a customer outreach program to determine timing for implementation and to negotiate terms for General Terms and Conditions for our agreements with our trading partner agencies.  IBC representatives will be contacting our primary points of contact within trading partner organizations to establish timelines for implementation of General Terms and Conditions (GT&Cs) as well as migrating our ordering processes to G-Invoicing.

While some of our trading partners do business with other parts of the U.S. Department of the Interior, due to the unique nature of IBC’s partnerships as a shared services provider for critical functions like payroll and financial management, IBC is planning to establish GT&Cs at the IBC level wherever feasible and at the line of business or service level if necessary. As such, multiple parties within DOI may contact you to establish GT&Cs for other services provided within DOI but outside IBC’s purview.
