GSA Schedule Categories & SINs Explained | Complete GSA Schedules List

Understanding how GSA Categorizes Products and Services

Prior to October 2019, this program was fragmented across 24 different schedules, and it was often unclear which schedule would best meet a firm's needs. To address this issue, GSA has since consolidated these schedules into a single master schedule, providing maximum flexibility for firms with diverse offerings.

Which GSA MAS SIN is Best for your Firm?

Although GSA’s consolidation of schedules simplifies access to the federal market, it also requires prospective contractors to carefully assess which of the 350 Special Item Numbers (SINs) best match their offerings. You should consult with our specialists to ensure your products and services are aligned with the most appropriate SIN—an essential step for positioning your company for success under the MAS program.

This single schedule allows you to offer products and services in the following major categories:

• Facilities
• Furniture & Furnishings
• Human Capital
• Industrial Products and Services
• Information Technology
• Miscellaneous
• Office Management
• Professional Services
• Scientific Management and Solutions
• Security and Protection
• Transportation and Logistics Services
• Travel

 TurboGSA works with you to strategically position and categorize your offerings within the GSA Schedule framework, ensuring they align with the most advantageous SINs to maximize visibility and drive meaningful contracting opportunities.
