The Federal Acquisition Service (FAS) WebBill system was developed by the Office of the Chief Financial Officer Heartland Financial Systems Division to allow GSA associates and FAS customers the ability to research and analyze their FAS billing information related to the leasing of government vehicles and/or the purchase of supplies efficiently through the Internet. If necessary, copies of the billing statements will also be available.

Customers also have the ability to generate reports, which can provide information such as, total dollars spent on office supplies during a given period or total number of vehicles leased per quarter, calendar year, and/or fiscal year. Customers can also download their billing information into Excel spreadsheets to facilitate their reconciliation process.
