How Detroit procurement works

The City of Detroit manages purchases and contracts through the Office of Contracting and Procurement, which publishes procurement notices, vendor registration instructions, and procurement policies.[1] Doing business typically requires vendor registration, submission of bids or proposals through the city portal, and adherence to specified insurance, licensing, and solicitation terms.[2]

Register early to receive bid notifications.

Key requirements for vendors

  • Vendor registration: use the city vendor portal and complete required profiles and certifications.[2]
  • Documentation: common documents include business license, W-9, proof of insurance, and any required professional licenses.

  • Equal opportunity and program compliance: follow any MBE/WBE/DBE requirements stated in solicitations and vendor policies.
