Wisconsin Government Contract Opportunities Guide
Step-by-step links and best practices for finding contracting opportunities from the State of Wisconsin, plus Wisconsin counties and key cities.
State of Wisconsin (VendorNet & eSupplier)
The State of Wisconsin posts contracting opportunities through VendorNet and manages vendor registration and purchase orders through eSupplier.
- Create/confirm your vendor account in eSupplier and add your NIGP / industry codes (so you receive notifications).
- Search VendorNet for open solicitations (RFB/IFB/RFP/RFQ) and download bid documents.
- Follow submission requirements exactly, including any mandatory addenda acknowledgements.
- If you have questions, email the contact person listed in the solicitation (not a general inbox unless instructed).
Tip: If you prefer a single place to start, begin with VendorNet and then register in eSupplier when you’re ready to bid and receive notices.
