Cooperative purchasing

Cooperative purchasing lets one public buyer use a contract another government or a purchasing cooperative already competed, instead of running its own solicitation. Statewide contracts that cities and schools may use, multi-state cooperative contracts, and GSA schedules opened to state and local governments all work this way.

GSA's Cooperative Purchasing program lets state, local and tribal governments buy IT, security and law-enforcement products and services, but only under eligible Multiple Award Schedule SINs; contractors may decline those orders.
