About the GSA Multiple Award Schedule

The GSA Multiple Award Schedule (MAS) is the federal government's premier contract vehicle, providing streamlined access to millions of commercial products and services at fair and reasonable prices. In 2019, GSA consolidated 24 separate schedules into a single MAS, organized by Special Item Numbers (SINs) that represent specific product and service categories.

Businesses holding GSA Schedule contracts can sell directly to federal agencies, state and local governments, and other eligible organizations. Each SIN represents a distinct category of offerings, from IT professional services and cloud computing to office furniture and building maintenance. Understanding which SINs align with your capabilities is essential for positioning your business in the federal marketplace.
