How to register, step by step
- 01
Register on E-Notify bid notification system
Start registration. Cost: No fee listed by the City of Milwaukee. The city invites all vendors to register for E-Notify, its exclusive bid notification system. Responses are uploaded to the city's Bonfire portal (cityofmilwaukee.bonfirehub.com) before the closing time; bids, but not RFP responses, may also be emailed.[2]
- 02
Choose your commodity codes
Notifications are sent by the codes in your vendor profile. Pick every code that describes your work, and revisit them when you add a service.
- 03
Get certified if you qualify
Small Business Enterprise (SBE) Program, through the City of Milwaukee Department of Compliance and Engagement.[3]

Watch the other buyers
State agencies in Wisconsin buy through the state portal, and school districts, transit agencies and utilities in the area usually post on their own sites. Registering with City of Milwaukee does not register you with them.
What you will typically need
Exact requirements vary by portal; the registration page linked above is the authority. Most ask for:
- Your legal business name and address exactly as registered with the state, and your federal tax ID (EIN, or SSN for some sole proprietors).
- A signed IRS Form W-9, which most buyers collect before they can pay you.
- Commodity codes (NIGP, UNSPSC or NAICS, depending on the portal) for every product and service you sell.
- A contact who will receive bid notices, plus any business license or registration the jurisdiction requires.
- Certificates of insurance and, for construction, bonding capacity: these are usually requested per bid rather than at registration.
