The Multiple Award Schedule (MAS) is organized by large categories, subcategories, and Special Item Numbers (SINs). The 12 large category pages provide information specific to each category.
GSA eLibrary is your one source for the latest GSA contract award information. You can access supplies and services directly from GSA MAS contractors through GSA Advantage!® or GSA eBuy. For more information on the ordering process click here.
Sellers who are considering becoming a GSA MAS Contractor must understand the category, subcategory, and SIN that their offerings fit under. Sellers should explore the information available on each category page and in the MAS solicitation.
