How to become a vendor for the City of Detroit: registration, certification, and bids

Detroit registers suppliers through the EUNA/Bonfire e-bidding portal and runs payments through Oracle. Getting CRIO-certified as a Detroit-based, minority-, or woman-owned business can earn a local preference on city solicitations. Here's the exact path.

Detroit spends heavily through its Office of Contracting and Procurement (OCP), and the city runs a real local-preference program that rewards businesses based in the city or owned by minorities and women. If you sell goods or services and you want a shot at city contracts, there are two separate tracks you need to handle: getting registered so you can receive and respond to bids, and getting certified so you qualify for preference. They live in different city offices and use different systems. Mixing them up is the most common reason new vendors stall.

Here is the actual path, what each step costs you in time, and where the leverage is.

Step 1: Register as a supplier

Detroit moved its bidding to an e-procurement platform branded EUNA, which suppliers reach through Bonfire at detroit.bonfirehub.com. This is where you create your vendor profile. The portal text and OCP pages reflected a transition still in progress when this was written, so confirm the live URL before you register.

When you register, you do three things:

  • Enter your organization name, contact email, and business information.
  • List the areas you service.
  • Select commodity codes that describe the goods and services you provide.

Those commodity codes are not paperwork. They are how the city decides which bid invitations land in your inbox. The OCP system emails you new opportunities matched to the codes on your profile. Pick them carefully and broadly enough to catch the work you actually want, because a too-narrow profile means you never hear about solicitations you could have won.

There is a second system you'll touch later. The City of Detroit continues to use Oracle for all contracts, purchase orders, invoicing, and payment. If you win an award, you register in Oracle so the post-bid side (the part where you get paid) can run. Think of it as two doors: Bonfire/EUNA to compete, Oracle to get paid. Maintain both accounts once you're active.

Step 2: Get CRIO-certified for local preference

Registration lets you bid. Certification can move you to the front of the line. The Civil Rights, Inclusion & Opportunity Department (CRIO) runs the Detroit Business Opportunity Program (DBOP), which certifies businesses that want to procure with the city. A DBOP certification can give you a competitive edge and makes you eligible for local preferences, when applicable, on city solicitations.

CRIO certifies several classifications, and you can hold more than one:

  • Detroit-Based Business (DBB)
  • Detroit Headquartered Business (DHB)
  • Detroit Resident Business (DRB)
  • Detroit Small Business (DSB)
  • Detroit-Based Micro Business (DBMB)
  • Minority-Owned Business Enterprise (MBE)
  • Woman-Owned Business Enterprise (WBE)
  • Construction Workforce Development Business (CWDB) and Construction Workforce Investment Business (CWIB)

The application is online. You select which certification(s) you're applying for and upload the required documents. After you submit a complete application, CRIO conducts a site visit to verify the business exists and operates as described. The whole process runs 30 to 40 days, and certifications are recertified annually, so put a calendar reminder a couple of months ahead of your expiration. Letting a certification lapse can knock you out of preference eligibility on an active bid.

One detail worth flagging: the city describes its preference as applying "when applicable" rather than publishing one fixed percentage that covers every solicitation. The weight of a local preference depends on the specific procurement. Read each bid's terms instead of assuming a flat bump.

Detroit-local vs. broader diversity certification

CRIO's MBE and WBE certifications are specific to the City of Detroit's program. They are not the same as the national NMSDC (MBE) or WBENC (WBE) certifications that corporate buyers and other agencies recognize, and they're separate from Michigan's state-level programs. If you plan to sell to the city, the State of Michigan, and corporate primes, you'll likely end up holding several certifications. Our state-by-state program directory shows how Michigan's programs line up alongside Detroit's, and the certifying-body directory maps which certification opens which door.

Step 3: Find and respond to open solicitations

Two ways to surface Detroit opportunities:

  1. Your inbox. Once your Bonfire/EUNA profile and commodity codes are set, the system invites you to matching opportunities by email. This is the lowest-effort channel and the main reason to get your codes right.
  2. The procurement portal directly. You can browse open solicitations in the city's procurement portal rather than waiting for an invitation. Check it on a schedule; do not rely only on email matching, because category mismatches happen.

When a solicitation interests you, submit your response through the e-bidding portal before the deadline. Late or off-platform submissions generally don't get reviewed. If you're awarded the contract, that's when the Oracle registration matters for the purchase order and payment.

The procurement office and how to reach a human

The Office of Contracting and Procurement sits in the Coleman A. Young Municipal Center, 2 Woodward Avenue, Suite 1008, Detroit, MI 48226. The office line is (313) 224-4600, open Monday through Friday, 8:00 a.m. to 4:00 p.m. OCP has also run "How to Navigate Oracle" e-procurement open assistance sessions for suppliers, which are worth attending if the portal trips you up. CRIO handles the certification side separately, so direct certification questions to that department rather than to OCP.

A realistic sequence

If you're starting cold, do it in this order:

  1. Register in Bonfire/EUNA and load accurate commodity codes. This alone gets you in the bid-notification stream.
  2. Apply for CRIO certification for every class you genuinely qualify for (a Detroit-headquartered, woman-owned firm should claim both DHB and WBE). Budget 30 to 40 days and prepare for the site visit.
  3. Watch both the portal and your email for solicitations, and respond on-platform before deadlines.
  4. Register in Oracle when you win, so invoicing and payment can flow.
  5. Recertify annually before your CRIO certification expires.

Local government work rewards businesses that get the paperwork done before the bid drops. The vendors who win Detroit contracts are usually the ones who registered, certified, and matched their commodity codes months earlier, then simply responded fast when the right solicitation hit their inbox.

Next step

If you're stacking certifications across the city, the state, and corporate programs, the document gathering is where most owners lose weeks. CertifyAll captures your business and ownership information once, then helps prepare and submit the certification applications you qualify for, so a Detroit CRIO filing and a national MBE or WBE application aren't two separate from-scratch projects. If you're not sure which certifications fit your business yet, start with our certification guides and come back to Detroit's registration once you know what you're pursuing.
