GSA MAS
The GSA Multiple Award Schedule (MAS) program provides federal, state, and local government buyers with easy access to commercial products, services, and solutions—all at pre-negotiated prices.

Key features of the MAS program:
- Long-term, government-wide contracts simplify the buying process
- Products and services are organized into subcategories and Special Item Numbers (SINs) for easier navigation
- Each SIN aligns with NAICS codes, making it straightforward for buyers to find what they need and for sellers to understand where their offerings fit
The MAS program streamlines procurement, saving time and effort for government buyers and commercial sellers alike.
