Federal Payments and Collections

The USCG has implemented the U.S. Treasury G-Invoicing solution for conducting business with other federal government agencies.  
G-Invoicing is a secure web-based intragovernmental (IGT) Buy/Sell transaction management system provided by U.S. Department of Treasury’s Financial Management Service. The service is available free of charge to all federal agencies. 

To request the payment status of an invoice vendors can contact the FSC Customer Service.

If you have any questions other than the payment status, please contact your Agency Representative/Contracting Officer’s Representative (COR) before contacting the FSC.
