How Cooperative Purchasing Streamlines the Procurement Process

  2. Region 4 issued the solicitation and any required amendments and notifications‚ and conducts pre–proposal conferences/meetings.
  3. Interested suppliers respond to the solicitation.

  5. All documentation is posted on www.nationalipa.org


All agreements offered through National IPA have been awarded via a thorough Request for Proposal (RFP) competitive solicitation by a public agency/governmental entity (e.g. state‚ city‚ county‚ public university or school district). The contracting process is the foundation of National IPA and sets them apart from other cooperatives. In order for even the most restrictive agencies nationwide to realize the best value offered by cooperative procurement‚ National IPA ensures that industry best practices‚ processes and procedures are applied. ​ Region 4 was the lead agency for Williams Scotsman. Procuring necessary products and services requires purchasing to navigate through an RFP process.
