Billing and Accounts Receivable (BAAR) Project

GSA is modernizing its core financial management system through the Billing and Accounts Receivable (BAAR) Project. Central to the BAAR Project is the three-phased release of the Vendor and Customer Self Service (VCSS) website. Once it is fully deployed, VCSS will provide all GSA customers with online access to their bills, statements and billing data, and paper bills and File Transfer Protocol (FTP) files will be phased out.

BAAR Phase 3 is currently in progress, and customers of all remaining GSA business lines will transition to VCSS in four separate waves. Wave 3.1 was completed in August 2014. For a complete list of business lines and implementation dates, please reference the Schedule by Phase.


  • Waves 3.1 and 3.2 focus solely on GSA Manual Business Processes;
  • Wave 3.3 will complete the implementation for all Manual Business Processes, as well as the Outlease Business Line; and
  • Wave 3.4 will include all remaining GSA business lines.

BAAR Phase 2B was completed in January 2014. Customers of GSA Global Supply, AutoChoice and select other business lines (see list of major business lines at began viewing bills, statements and billing data in VCSS, which replaced WebBill and paper bill statements.

BAAR Phase 2A was completed in July 2013. GSA customers of Reimbursable Work Authorizations (RWA), and customers in Washington, D.C., receiving steam and chilled water through the Heating Operation and Transmission District (HOTD), began viewing bills, statements and billing data in VCSS. VCSS replaced BillView and paper bill statements for all RWA customers, except customers of IT services.

BAAR Phase 1 was completed in August 2011. GSA Fleet and PBS Rent began viewing bills, statements and billing data in VCSS.
