How to sell to Michigan government

State agencies post on SIGMA Vendor Self Service (SIGMA VSS).^[1] Bids under $50,000 usually do not appear in SIGMA VSS, so contact agency buyers listed at Michigan.gov/MiProcurement for smaller work.

1. 01

   Register on SIGMA VSS vendor account

   Start registration. Cost: Free. You must register and get a SIGMA VSS account to bid on open solicitations. Enter all commodity codes, business types and an email address that apply to you; codes drive bid notices.^[2]

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.

3. 03

   Get certified if you qualify

   Geographically Disadvantaged Business Enterprise (GDBE), through the Michigan DTMB Procurement. Not a separate application: Michigan-based firms in a Qualified Opportunity Zone (or with most staff working or living in one) or SBA HUBZone-certified add the GDBE business type to their SIGMA VSS profile.^[3]

4. 04

   Watch the other buyers

   Cities and counties in Michigan run their own vendor systems. See the guides for City of Detroit below.

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.

SIGMA VSS lists state opportunities over $50,000; buys under $50,000 are not typically posted, so market directly to state departments.^[2]

• Michigan schools and local governments also post in SIGMA VSS, so the right commodity codes can bring you local bid notices too.
• You can pitch new or cost-saving products through the state's Vendor Innovation Portal at Michigan.gov/VendorInnovation.
