BAAR offers many benefits to GSA and GSA customers by:

  • Improving GSA’s ability to provide timely and accurate financial information for customers
  • Enabling GSA customers to access and download bills and billing information electronically through the Vendor and Customer Self Service (VCSS) website
  • Phasing out paper bills and the delivery of electronic billing files by e-mail or file transfer protocol (FTP)
  • Reducing the use of printed paper to support GSA’s efforts to achieve a “Zero Environmental Footprint”
  • Allowing agencies to manage access to their billing and collection data through VCSS, by providing improved security and greater customer control
  • Supporting the governmentwide efforts to standardize financial management and the way billing data is populated in the Treasury Intragovernmental Payment and Collection (IPAC) files
