Vendor Self Service

The ColoradoVSS website allows vendors to manage their account, review and respond to solicitations. Most State agencies and many Institutions of Higher Education post solicitations for goods, services, and construction notices on the ColoradoVSS website

Registration is free. Adding commodity codes during the registration process allows vendors to receive email notifications for new solicitations. Registration instructions are found under the Links section of this page.
