How to register as a vendor with City and County of Denver

City and County of Denver posts its solicitations on Rocky Mountain E-Purchasing System (BidNet Direct).^[1] Parks and Recreation and Denver Arts & Venues have their own BidNet agency pages, separate from General Services Purchasing.

Changed recently: Denver removed its DBE reevaluation guidance and is updating it to match the U.S. DOT final rule on the federal DBE program.^[3]

1. 01

   Register on BidNet Direct (Rocky Mountain E-Purchasing System) registration

   Start registration. Cost: Free. Basic BidNet registration is free; BidNet sells optional extra services. City RFPs require bidders to register with BidNet and may treat unregistered proposers as non-responsive.^[2]

2. 02

   Choose your commodity codes

   Notifications are sent by the codes in your vendor profile. Pick every code that describes your work, and revisit them when you add a service.

3. 03

   Get certified if you qualify

   SBE, EBE, M/WBE, SBEC, DBE and ACDBE certification, through the Denver Division of Small Business Opportunity (DSBO). $200 non-refundable application fee for city certifications; DBE and ACDBE are free. Apply at denver.mwdbe.com.^[3]

4. 04

   Watch the other buyers

   State agencies in Colorado buy through the state portal, and school districts, transit agencies and utilities in the area usually post on their own sites. Registering with City and County of Denver does not register you with them.

Exact requirements vary by portal; the registration page linked above is the authority. Most ask for:

• Your legal business name and address exactly as registered with the state, and your federal tax ID (EIN, or SSN for some sole proprietors).
• A signed IRS Form W-9, which most buyers collect before they can pay you.
• Commodity codes (NIGP, UNSPSC or NAICS, depending on the portal) for every product and service you sell.
• A contact who will receive bid notices, plus any business license or registration the jurisdiction requires.
• Certificates of insurance and, for construction, bonding capacity: these are usually requested per bid rather than at registration.

Formal solicitations of $150,000 or more are posted on BidNet with public bid openings; informal bids under $50,000 usually have no public opening.^[4]

• Denver has no local or State of Colorado bid preference.
• Some Parks contracts are limited to Denver-certified SBE or M/WBE firms, so certify early if you qualify.
