How to register as a Michigan vendor, step by step

These are the steps as the state describes them, in plain words. The portal may word things differently, and it can change, so keep the official page open beside you.

Register for a free SIGMA VSS account; the state posts all of its bid opportunities there and you need an account to bid.
Fill in your profile with your commodity codes, business types and the email addresses that should get notices (DTMB publishes commodity code lists, including IT codes).
Use SIGMA VSS to find and answer solicitations and to track state payments.
Keep the profile current whenever anything about your company changes.
If your business is Michigan-based and in a low-income or designated area, look at the Geographically Disadvantaged Business Enterprise (GDBE) program.

What to have ready before you start

Registration goes faster when the basics are in front of you. For Michigan, gather:

Your legal business name exactly as it appears on your tax records, and any trade name you use.
Your federal Employer Identification Number (EIN), or a Social Security number for a sole proprietor, since the state uses it to match you for payment.
A business address, a phone number and an email address that someone reads every day; bid notices and questions from buyers go there.
A short list of what you sell, so you can choose the matching SIGMA commodity codes codes in one sitting.
Food service vendors also need a food service license from the Michigan Department of Agriculture & Rural Development

Does it cost anything to register in Michigan?

No fee is stated on the official pages we read: Free: the official page says registration is free. Be careful with outside services that offer to register you for a price. The state's own portal is where registration happens, and Michigan does not require you to use a paid middleman to sell to its agencies. Some separate things can cost money, such as a notary for a form, a professional license, insurance or a bid bond on construction work.

Which commodity codes does Michigan use?

Michigan matches vendors to bids with SIGMA commodity codes (DTMB commodity code list; base system not named on the page read). The state uses its own list of commodity or service codes. Choose every code that truly matches your work, because those codes decide which bid notices are emailed to you. If you also want federal work, you will need NAICS codes for SAM.gov; our free NAICS code lookup and the guide what a NAICS code is help you pick them.

Certification programs in Michigan

Certification is separate from registration. You can register and bid without it, but a certificate can open set-aside contracts or count toward goals that agencies and prime contractors have to meet. The programs the state points to:

DBE. A Disadvantaged Business Enterprise (DBE) certification comes from the U.S. Department of Transportation program that each state runs through a Unified Certification Program. It matters most on road, transit and airport jobs paid for with federal transportation money, where prime contractors set DBE participation goals.

Small business. Small business programs reserve some purchases for firms under a size limit, or give them a preference when bids are close. The size limits are set by each program, not by the federal SBA tables, so check the state's own definition.

Federal programs such as 8(a), HUBZone, women-owned (WOSB) and service-disabled veteran-owned (SDVOSB) are certified by the U.S. Small Business Administration, not by the state; see small business set-asides explained.

Cities, counties and school districts in Michigan

Michigan's MiDEAL program lets local governments buy from state contracts, but cities, counties and schools still run their own bids, so check their own sites too.

Large local governments in Michigan include Detroit, Grand Rapids. Each one usually keeps its own vendor list and posts its own bids, so register with the ones you want to sell to as well.

EasBid reads many of these local sources together with the state's, so one search shows state and local bids side by side.

Federal contracts in Michigan

A Michigan registration covers state agencies only. Federal agencies, including the military bases, VA medical centers and national parks in Michigan, buy through SAM.gov, which has its own free registration and gives you a Unique Entity ID. Our step-by-step guide to registering in SAM.gov walks through it, and federal bids on EasBid lists open notices.

Tips for your first Michigan bid

Read the whole solicitation before you price anything; the due date, the question deadline and the submission method are usually on the first pages. Our guide on reading a solicitation shows what to look for.
Ask questions in writing before the question deadline. Answers are usually posted as an addendum that every bidder can see.
Check whether the bid needs a license, insurance certificate or bond, and get those started early.
Submit through the channel the notice names, SIGMA Vendor Self-Service or otherwise, and leave a day of margin; late bids are normally rejected.
Whether you win or lose, ask for the award results. They show the winning prices and help you price the next one.
