While email notifications are available, we recommend vendors check websites regularly to ensure opportunities are not missed.


  • Vendors can respond to select solicitations online.
  • Vendors can register for FREE and update account information.
  • 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.
  • Instructions are posted on the ColoradoVSS website in the Quick Start Guide to help all vendors access the website for the first time.
