The GSA Multiple Award Schedule (MAS) Program is the premier contract vehicle for the federal government. The MAS program is a long-term governmentwide contract between commercial suppliers and the federal government.
 
Suppliers give federal, and in some cases state and local buyers (including tribal governments and some educational institutions), access to millions of commercial products and services at negotiated ceiling prices.  Although MAS is the premier vehicle for government sales, including federal, state, and local government agencies, it is not a mandatory source. Getting a MAS contract does not guarantee business with the government.
