Vendor Self Service

The ColoradoVSS website allows vendors to manage vendor account information, review and respond to solicitations. Most State agencies and many institutions of higher education post solicitations for goods and services as well as construction notices in ColoradoVSS.

There is no cost to register. During the registration process, vendors are able to select NIGP commodity codes for goods and services. Vendors are notified via email of new solicitations pertaining to the commodity codes selected in their registration / account profile. We recommend a broad approach in selecting commodity codes and checking the website frequently so no opportunities are missed. For more information on how to do business with the State of Colorado please click on the ACCESSColorado link at the top of the page.

Detailed registration instructions can be found in the Vendor Registration Quick Start Guide.
