How to View Bidding Opportunities:

In the spirit of continuous improvement and cost management, the City and County of Denver has joined the Rocky Mountain E-Purchasing System. The Rocky Mountain E-Purchasing System (BidNet) is an online notification system that is being utilized by multiple governmental entities. Participating entities post their bids, quotes, proposals, addendums, and awards on this one centralized system. Review bids or register by continuing to this link:

Vendor registration is FREE; however, vendors may elect to receive automatic e-mail notification of all open solicitations matching their vendor profile for an annual fee. If a vendor does not select the upgraded option, it is the responsibility of the vendor to monitor the website regularly in order to be aware of business opportunities and review changes or addendums to bids, quotes, and proposals. Vendors who upgrade to receive email notifications will receive opportunities matching their business goods/services provided automatically.

For additional information please contact Contract Administration at 720-944-2233. For help registering or questions about the Rocky Mountain E-Purchasing System, please contact IPT by BidNet at 800-835-4603 to speak with the Vendor Support Team.

As of July 2019, all bidding opportunities are posted to BidNet Direct.

The bid opportunity, which is usually detailed in a Request for Application or Request for Proposal, will include instructions about who to contact with questions. Please direct your questions to that person and pay special attention to any deadlines or instructions that are provided.

Helping a larger, more diverse field of businesses compete for government contracts is an important way that the City and County of Denver helps small businesses grow and increase their revenues. Qualifying factors for certification include being minority or woman-owned, or otherwise being a disadvantaged business.

The City and County of Denver certifies businesses in several categories through the Office of Economic Development’s Division of Small Business Opportunity. Visit their website to learn more about what certification means and how to apply.
