What is a Lead Agency in public sector cooperative purchasing?

A Lead Agency is the originating entity in the public sector that competitively solicits and awards a contract to a vendor for products and services. This process is known as public sector cooperative purchasing, which is governed by applicable state laws. State laws allow public sector entities to then leverage or “piggyback” off Lead Agency contracts and achieve economies of scale they would likely not receive by contracting on their own with a vendor.
