Overview for MAS buying
Our Multiple Award Schedule program allows federal agencies, state and local governments, and other authorized organizations to place orders against our MAS contracts. MAS ordering procedures are available at GSAR subpart 538.71. These ordering procedures implement the Revolutionary FAR Overhaul model deviation text for FAR part 8. For agencies that follow the FAR, if you are unsure if your agency has a Class Deviation in place to implement the RFO part 8, contact your internal acquisition policy office for clarification.
The Department of Veterans Affairs has delegated authority from us [PDF - 1 MB] to carry out a similar program for medical products and services.

How to prioritize MAS use
In accordance with FAR 8.104 (GSA Class Deviation RFO-2025-08), if a commercial product or service meets your needs and is available on a governmentwide contract, like MAS, you must use it if it’s a “required use” contract. If not “required use,” you should consider using it.
