Key takeaways
- Colorado's central procurement office is Office of the State Controller, State Purchasing & Contracts Office (SPCO), and vendors register through ColoradoVSS.
- Registration fee: Free.
- Registering makes you visible to state buyers; it doesn't guarantee business.
- Local governments, school districts and universities in Colorado often have their own vendor systems.

How to register, step by step
- Gather your information. Have these ready: Commodity codes for solicitation alerts.
- Register in ColoradoVSS. Start at prd.co.cgiadvantage.com. Use your exact legal name and taxpayer ID so your record matches tax and payment systems.
- Describe what you sell. If the system asks for commodity or service codes, choose them carefully: agencies and bid notices often use them to find vendors.
- Keep your profile current. Update contacts, codes and documents so notices and purchase orders reach the right people.
- Look beyond the state. Cities, counties, school districts, universities and utilities in Colorado often run their own vendor registration and bid systems.
Good to know
Procurement is decentralized; CDOT uses its own CDOT Business Center instead of ColoradoVSS.
After you register
Registration is the entry ticket, not the sale. Most state purchases above small-dollar thresholds go through competitive bids or existing contracts, including cooperative contracts many agencies use. Watch the state's bid notices, learn which contracts agencies buy from, and start conversations with the program staff who own the problems you solve before a solicitation is written. Our guides to government buying signals and cooperative purchasing explain how.
