Colorado Vendor Self Service (ColoradoVSS) is the vendor-facing component of the CORE system. Most State Agencies and many Institutions of Higher Education are posting solicitations for goods and services as well as construction notices in ColoradoVSS.

  • Vendors can register for free and update account information
  • Vendors do not need to be registered in VSS to view and respond to solicitations
  • NIGP commodity codes are used to identify products or services offered by vendors
  • Email notifications (for new solicitations) are sent based on commodity codes selected
  • In order to ensure the integrity of our vendor records, we verify information through Dun and Bradstreet
  • For a complete listing of where solicitations are being posted, please visit the State Purchasing Office website.
