Frequently Asked Questions
1. What is cooperative purchasing?
Cooperative purchasing allows state and local governmental entities, public and private primary, secondary and higher education entities, non-profit entities, and agencies for the public benefit to leverage their collective purchasing power to obtain the best overall value from suppliers. Through a cooperative purchasing organization like OMNIA Partners, agencies gain access to competitively solicited contracts that simplify the public procurement process and eliminate the need for individual solicitations. This approach streamlines purchasing, saves time, and ensures compliance with applicable procurement regulations.
2. How does cooperative purchasing work?
Cooperative purchasing streamlines the sourcing and procurement process by allowing a Lead Public Agency to conduct a solicitation on behalf of multiple participants. Once awarded, the resulting cooperative purchasing agreement becomes available for other agencies to use, saving months of research and solicitation. Members can purchase directly from trusted suppliers using these contracts, reducing their administrative workload and ensuring transparency throughout the procurement and contracting process.
3. Why do public agencies use cooperative purchasing?
Public agencies rely on cooperative purchasing to save time, reduce costs, and stay compliant with public sector procurement requirements. By using established cooperative purchasing Master Agreements, the solicitation process has already been done helping agencies go right to achieving competitive pricing and quality service. This approach enhances efficiency, enables more strategic procurement, and allows organizations to focus resources on mission-critical priorities rather than administrative tasks.
4. Who can use cooperative purchasing?
Eligibility for cooperative purchasing extends to a wide range of public and nonprofit entities, including but not limited to state procurement agencies, local county procurement offices, special districts, education procurement institutions, and organizations involved in nonprofit procurement. Once these agencies become a member of a cooperative purchasing organization like OMNIA Partners, they gain access to compliant, competitively solicited Master Agreements that simplify purchasing while ensuring accountability and transparency in every transaction.
