Michigan SIGMA VSS (Statewide Integrated Governmental Management Applications Vendor Self-Service) is Michigan's eProcurement portal for state agency solicitations managed by the Department of Technology, Management & Budget (DTMB). It covers MDOT, MDHHS, DTMB, and 20+ agencies spending $12B+ annually — plus the "Pure Michigan Business Connect" supplier diversity program connecting vendors to state procurement opportunities.
Register on Michigan SIGMA VSS at sigma.michigan.gov — registration is free and required to receive notifications and submit bids through Michigan's eProcurement system
Complete your commodity code profile — Michigan uses NIGP (National Institute of Governmental Purchasing) commodity codes. Select all applicable codes broadly; you can refine after reviewing notification volume
Apply for Michigan's SBE (Small Business Enterprise) or Disadvantaged Business Enterprise certification at michigan.gov/dtmb — certified firms receive preference on applicable state contracts
For MDOT construction, register separately with MDOT at michigan.gov/mdot — MDOT has its own prequalification system and DBE program separate from SIGMA for highway construction contracts
Register with DTMB's Information Technology procurement group separately for IT contracts — DTMB manages Michigan's statewide IT contracts through a separate track from general commodity procurement
MDOT is Michigan's largest buyer at $2B+ annually, executing the Rebuilding Michigan bond program and a significant bridge replacement backlog. MDOT's 7 Transportation Service Centers each have procurement authority — build relationships at the TSC level for consistent construction and engineering work.
Michigan's auto industry legacy means the state is one of the most active buyers of advanced manufacturing, engineering, and supply chain services in the Midwest. MEDC (Michigan Economic Development Corporation) and DTMB both post manufacturing-adjacent contracts that benefit firms with automotive supply chain experience.
MDHHS (Michigan Department of Health and Human Services) spends $3B+ annually on Medicaid managed care and IT — it's the second-largest state agency buyer. MDHHS's CHAMPS system modernization and Medicaid IT programs create multi-year IT contracting opportunities separate from general SIGMA procurement.
Michigan's statewide contracts through DTMB — called "Statewide Contracts" — give access to all state agencies, universities, and many local governments without competitive bidding. Monitor michigan.gov/dtmb/procurement for open statewide contract solicitations. These are the highest-leverage placements in Michigan procurement.
The EV transition is creating unprecedented procurement activity across Michigan — battery manufacturing, charging infrastructure, grid upgrades, and workforce development contracts are flowing through state agencies, utilities, and regional planning bodies simultaneously. Track MEDC and Michigan Public Service Commission procurement alongside SIGMA.
Michigan SIGMA and the state's procurement system are technically run by DTMB, but MDOT operates almost entirely independently for construction — MDOT has its own BidExpress-based letting system, its own prequalification, its own DBE program, and its own contracting staff. Construction firms who only monitor SIGMA miss MDOT entirely. Monitor both sigma.michigan.gov and michigan.gov/mdot separately.
Michigan's "Purchasing Operations" page at michigan.gov/dtmb/procurement is where statewide contract solicitations are posted — these are separate from SIGMA vendor notifications and many vendors miss them entirely. If you're pursuing a statewide contract, you need to monitor both SIGMA and the DTMB procurement page simultaneously.
Michigan has a strong cooperative purchasing program through MITN (Michigan Inter-governmental Trade Network) that connects state contracts to local governments. A Michigan statewide contract award can generate revenue from Detroit, Grand Rapids, Ann Arbor, Lansing, and hundreds of municipalities without separate competitive processes.
The Flint water crisis and subsequent Michigan water infrastructure investment created a sustained pipeline of water system construction and environmental services contracts across the state. EGLE (Environment, Great Lakes & Energy) and MDHHS both post environmental and public health infrastructure contracts that extend well beyond the original Flint response.
Michigan's SBE (Small Business Enterprise) and Disadvantaged Business Enterprise programs certify qualifying businesses for state contract preferences. Michigan uses the federal DBE program for federally-funded transportation contracts through MDOT. The Pure Michigan Business Connect program actively connects state agencies with Michigan-based small and diverse suppliers — certified firms are promoted directly to agency procurement officers through the program.

Michigan SIGMA VSS is the state's eProcurement portal managed by DTMB. State agencies post solicitations here. Major buyers include MDOT ($2B+), MDHHS ($3B+), DTMB, EGLE, and 20+ agencies. However, MDOT highway construction uses a separate system — most MDOT construction is posted through BidExpress at michigan.gov/mdot, not SIGMA.
No — MDOT highway construction contracts are posted separately through MDOT's letting system at michigan.gov/mdot, not through SIGMA VSS. MDOT uses BidExpress for construction bid solicitations. You need both SIGMA registration (for state agency services and IT) and MDOT registration (for highway construction) for complete Michigan coverage.
Michigan Statewide Contracts are pre-negotiated master agreements managed by DTMB that allow all state agencies, universities, and many local governments to purchase directly without competitive bidding. They're Michigan's equivalent of GSA Schedule. Statewide contract solicitations are posted at michigan.gov/dtmb/procurement — separate from SIGMA VSS notifications.
Pure Michigan Business Connect is MEDC's supplier diversity program that actively connects Michigan-based small and diverse businesses with state procurement opportunities. Enrolled firms are promoted directly to agency procurement officers and receive advance notice of upcoming opportunities. Register at michiganbusiness.org/pure-michigan-business-connect.
