How to register to bid in Wisconsin

Where to register
State of Wisconsin eSupplier Portal (bidder registration)
Cost to register
Free ("Registration on eSupplier is available free of charge")
Where Wisconsin posts bids
vendornet.wi.gov
  1. Go to eSupplier (portal_url above). DOA also links a short bidder registration video.
  2. Create a WAMS username and password (Wisconsin's state login) using the link below the sign-in button.
  3. Sign in to eSupplier with your WAMS login.
  4. Choose Register and fill out the registration form with your company information.
  5. Add your NIGP codes so you get notices.
  6. To bid, open the solicitation while signed in. The FAQ says the response button only appears for registered, signed-in users.

If you were registered on the old VendorNet system, use the same email when you register on eSupplier. DOA says your previous NIGP codes will carry over if your account was active at the time of the move.

What to have ready
  • An email address you check
  • Company information: legal name, address, and contacts
  • FEIN/EIN (or SSN for a sole proprietor) and a W-9 for when you're awarded work and need to be paid. The DOA bidder materials don't list these as registration fields.
  • NIGP codes for "the services and commodity areas your company is interested in providing" (you need at least one)
