The State of Michigan spends billions a year on goods, services, and construction, and almost all of it flows through one purchasing authority and one vendor portal. If you own a diverse, minority, women, veteran, or small business and you want a piece of that, the path is more straightforward than the federal side. There's no SAM.gov-style validation wait, and the first step is free.
Here's what actually matters: who buys, where you register, what certification does (and doesn't) do in Michigan, and the two preferences that can swing a close bid in your favor.
Who you're selling toState of Michigan Procurement, housed inside the Department of Technology, Management and Budget (DTMB), is the state's central purchasing office. Most contracts for goods and services run through DTMB, with some authority delegated to individual agencies. That centralization helps you. Learn one portal and one set of rules, and you can chase work across dozens of departments.
DTMB runs a public-facing hub called Contract Connect at michigan.gov/dtmb/procurement. It's the front door for vendors: how to register, where bids post, the active contract list, and the program and preference policies. Bookmark it.
Step one: register in SIGMA VSS (it's free)Every state bid posts through SIGMA Vendor Self-Service (VSS), the state's eProcurement system. You need a SIGMA VSS account to respond to a solicitation, so this is the real starting line. Registration costs nothing. Anyone charging you to "register your business with Michigan" is selling you something the state gives away.
Before you start, pull together:
- Your legal business name and address as they appear on your tax records.
- Your EIN or FEIN (or Social Security number if you operate as an individual). SIGMA generates a substitute W-9 from what you enter, so accuracy matters for getting paid.
- Your banking details for electronic funds transfer, which is how the state pays.
- The commodity codes that describe what you sell.
That last one is easy to skip and costly to skip. Adding your commodity codes and a monitored email address to your SIGMA VSS profile is the only way the system notifies you when a matching bid drops. No codes, no alerts, and you'll be finding out about solicitations after they close.
If you get stuck, the SIGMA VSS Support Center answers at SIGMA-Vendor@Michigan.gov or 517-284-0540. Registration is data entry, not a review queue, so most owners finish in an afternoon.
Step two: find the bidsOnce you're in SIGMA VSS, open solicitations live there too. Two more tools on Contract Connect are worth a weekly look:
- The Vendor Opportunity Dashboard, which shows bids the state is actively developing and re-bids it's planning, sometimes months before the formal solicitation. That lead time lets you line up partners or past performance before the clock starts.
- The Contract List, a directory of active statewide contracts. If a contract covering what you sell already exists and runs for years, your real opening might be the next re-bid or a subcontract with the current holder, not a fresh solicitation.
Reading expired and current solicitations in your category is the fastest way to learn how the state writes requirements and what it pays. Do that before you write your first response.
What certification does in MichiganThis is where Michigan differs from what a lot of owners expect. The state does not run its own minority-owned (MBE) or women-owned (WBE) business certification that hands you a procurement preference. There is no statewide MBE/WBE set-aside the way some states operate one.
What exists instead:
MBE certification runs through the Michigan Minority Supplier Development Council (MMSDC), the state's affiliate of the National Minority Supplier Development Council. MMSDC certification requires 51% or more minority ownership, operation, and control, and the review can take up to 90 days, including a pre-certification briefing and a site visit. That certification is built mainly for the corporate market. It gets you into the NMSDC national database that large companies search when they're sourcing diverse suppliers. If your buyers include automakers, health systems, or other Fortune 500 firms with supplier diversity programs, this is the credential that opens those doors. It's powerful, just not a state-procurement preference.
So in Michigan, treat corporate certification and state selling as two separate plays. Certification matters enormously for the private sector. For state contracts, registration and the right preference flags matter more.
The two preferences that can win you a close bidMichigan does give pricing edges in two places. Both are worth claiming if you qualify.
Service-Disabled Veteran-Owned Business (SDVOB) preference. Under Public Act 91 of 2005, a business that is 51% or more owned by one or more veterans with a service-connected disability can receive up to a 10% pricing preference on state bids. Public Act 133 of 2008 set a goal of awarding 5% of total state spending on goods, services, and construction to qualified SDVOBs. On a competitive bid, a 10% scoring edge is large enough to flip an award.
Here's the part owners miss: Michigan does not pre-certify SDVOBs and doesn't rely on the federal CVE database. You claim the preference inside each bid response and attach the proof, a DD-214 or equivalent for service and discharge, and a DD-214 or VA Rating Decision Letter documenting the service-connected disability, plus ownership documents. The state will also accept a National Veterans Business Development Council (NVBDC) certification as verification when its conditions are met. No separate state application stands between you and the preference. You assert it, with documents, every time you bid.
Michigan-based preference. All else equal, the state gives preference to products manufactured or services offered by Michigan-based firms. There's also a reciprocal preference: if you certify as a Michigan business and you're bidding against a vendor from a state that penalizes out-of-state bidders, Michigan applies a matching preference in your favor. If your business is in-state, say so in your bid.
If the idea of set-asides and preferences is new to you, our explainer on how federal set-asides work lays out the mechanics, then read Michigan's rules as the lighter-touch state version.
The Michigan Supplier Community (MiSC)DTMB tracks diverse and small vendors through the Michigan Supplier Community (MiSC) program. Be clear about what it is. MiSC is a recognition and visibility program, not a pricing preference. You register and self-identify your business types in SIGMA VSS, and the state uses that data to measure and report diverse and small-business participation.
The categories include veteran-owned and SDVOB firms and the Michigan Geographically Disadvantaged Business Enterprise (GDBE). To qualify as a GDBE, your business must be Michigan-based and either be a certified Michigan SBA HUBZone, sit inside a Michigan Qualified Opportunity Zone, or have most of its employees working in or living in one. Selecting the right MiSC categories costs nothing and improves how visible you are when the state runs market research. Do it while you're registering.
A realistic first 30 daysYou don't need to do everything at once. A workable order:
- Week 1. Register in SIGMA VSS, load your commodity codes, and flag your MiSC categories. Confirm your banking details so payment isn't a problem later.
- Week 1–2. Read three to five recent solicitations in your category. Note the format, the evaluation criteria, and the incumbent if there is one.
- Week 2–3. Get free help. Michigan's APEX Accelerators (the program that replaced the old PTACs) will walk you through SIGMA registration, market research, and your first bid at no cost. Use them.
- Ongoing. Watch the Vendor Opportunity Dashboard for upcoming work, and respond to your first solicitation when one fits. If you qualify for the SDVOB preference, build a reusable documentation packet now so you're not scrambling at a deadline.
State registration gets you bidding. But Michigan is a corporate supplier-diversity powerhouse, with anchor buyers in automotive, healthcare, and energy that spend heavily with certified diverse firms. If that's your market too, getting properly certified is what puts you in the databases those buyers search. List your business in our supplier directory so corporate buyers can find you, and if you want certification handled across agencies without doing each application yourself, CertifyAll files for the state and federal certifications you qualify for, once, from a single profile.
Michigan won't make you wait through a federal-style validation to start. Register, flag what you are, claim the preference you've earned, and bid.
