About CoPro+
Introducing CoPro+
Back in 2011, some of MAC’s member counties were struggling from revenue cuts. These changes had major impacts on their teams and their ability to efficiently provide public services. It seemed like these members were all suffering from fewer team members and less time to handle public purchasing requirements. These hurdles are what inspired MAC to create Collaborative Procurement Plus, better known as CoPro+.
Essentially, CoPro+ serves as a bridge between public agencies (like schools and local governments) and vetted, trustworthy contractors who are waiting to fulfill procurement requests. Our program supports Michigan companies, provides resources for public agencies, creates real cost and time savings, and, above all else, makes procurement a breeze.
Since CoPro+ was established in 2012, the number of available contracts has continued to double every year, with sales volumes to match.








Procurement Made Easy
- NO FEES to join. That’s right. Membership is free!
- End-to-end procurement support. Post-award contract administration ensures contracts provide great value throughout the entire period, and not just the first year.
- Shared collected fees. CoPro+ is the ONLY cooperative purchasing organization in the country that shares collected fees with every active participant on every sponsored contract in the form of a dividend.
