How GSA Buys: Schedules and Contracts

GSA uses a variety of contracting vehicles to effectively manage procurement for both its own operations and its government customers.


Under the GSA Schedules Program (also referred to as Multiple Award Schedules and Federal Supply Schedules), GSA establishes long-term governmentwide contracts with commercial firms to provide access to more than 11 million commercial supplies (products) and services. While the GSA Schedules Program is only one procurement vehicles, it is one of the largest programs and the most preferred for commercial products and services.

The MAS Program was designed to provide discount resources to all GSA federal agencies worldwide, as well as state and local governments. When you have a contract with GSA under this program, you may sell to any government agency with just one source instead of having separate contracts with each agency.

Blanket Purchase Agreement (BPA)

A GSA Schedules BPA is an agreement established by a customer with a GSA Schedules contractor to fill repetitive needs for supplies or services (Federal Acquisition Regulation 8.405-3). It simplifies the filling of recurring needs, while leveraging a customer's buying power by taking advantage of quantity discounts, saving administrative time and reducing paperwork.
