Due to the COVID-19 pandemic, our team has shifted to working remotely. As a result, we are not able to take initial issue contact via telephone. Please contact the ColoradoVSS Help Desk by email at vsshelp@state.co.us. We appreciate your patience and understanding. 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.
