About Wisconsin government procurement

Wisconsin state procurement is centralized through the Wisconsin Department of Administration (DOA) State Bureau of Procurement and runs on VendorNet at vendornet.wi.gov. All executive-agency solicitations over $50,000 flow through VendorNet. Wisconsin awarded approximately $8 billion in commodities, IT, professional services, and construction contracts in FY24 across state agencies plus the University of Wisconsin System (13 comprehensive universities), the Wisconsin Technical College System (16 colleges), and the Wisconsin Department of Transportation.

The Wisconsin Department of Transportation (WisDOT) is the largest state buyer, running approximately $2 billion in annual highway, bridge, and multimodal construction lettings through the WisDOT bidding system. Bidders must complete WisDOT Contractor Prequalification for financial capacity, past performance, and equipment. Federal-aid projects carry Davis-Bacon wages, Buy America iron/steel, and DBE subcontracting goals typically 8-12%. WisDOT also runs specialty programs including the Southeast Wisconsin Freeways initiative and Zoo Interchange reconstruction.

Wisconsin's Minority Business Enterprise (MBE) program targets 5% of state contract dollars for certified minority-owned firms. Wisconsin Woman-Owned Business Enterprise (WBE) is a parallel certification. Combined DVB (Disabled Veteran-Owned Business) certification is offered. Certification is through the DOA Minority Business Development office. Wisconsin does not require state prevailing wages on state-funded public works — the state repealed its Little Davis-Bacon requirements in 2015 (state-funded) and 2017 (local-funded). Federal Davis-Bacon still applies on federal-aid work.

Local procurement runs on many platforms. Milwaukee uses MKE Purchasing at city.milwaukee.gov/purchasing. Madison uses MadisonBids. Milwaukee County, Dane County (Madison), Waukesha County, and Brown County (Green Bay) each run separate procurement systems. Wisconsin's 72 counties and 596 municipalities each publish RFPs independently. School districts across 421 Wisconsin school districts each publish RFPs independently — Milwaukee Public Schools, Madison Metropolitan, Waukesha, Green Bay Area, and Kenosha Unified are among the largest. Emerging demand: Foxconn / Microsoft Racine County data center procurement (Microsoft acquired the site in 2024), plus IRA-funded rural broadband and PFAS remediation at Wisconsin Department of Natural Resources.

Largest Wisconsin state buyers

The largest Wisconsin state buyers are the Wisconsin Department of Transportation (WisDOT — $2B+ annual lettings), Department of Administration (DOA commodities and IT), Department of Corrections, Department of Health Services, University of Wisconsin System (13 comprehensive universities plus UW Health), Wisconsin Technical College System (16 colleges), Department of Natural Resources, Department of Public Instruction, and Department of Workforce Development. Milwaukee, Madison, Milwaukee County, Dane County, Waukesha County, and Brown County are the largest local buyers. Milwaukee Public Schools and Madison Metropolitan are major school-district buyers. Foxconn/Microsoft Racine data center is driving significant adjacent procurement.

Vendor rules that matter in Wisconsin

Wisconsin does not require state prevailing wages on state-funded public works (repealed 2015/2017) — federal Davis-Bacon still applies on federal-aid. Milwaukee, Madison, Milwaukee County, and Dane County each require separate registrations on their own platforms.
