CTsource is a secure, web-based statewide eProcurement system implemented by the State of Connecticut with its partner, Perfect Commerce LLC (a PROACTIS Company), using their WebProcure application to streamline how companies do business with the State.

CTsource is a one-stop shop to register, manage, search, view and respond to all solicitation and contract related activities that DAS Procurement and DAS Construction Services are tasked with. Once registered with CTsource, suppliers are able to maintain and manage their profile which includes modifying contact persons, business address, email addresses and much more. Additionally, suppliers will be required to select the UNSPSC code(s) that best apply to their organization’s business in order to receive automated email invitations notifying them of solicitation opportunities!

Note: All features will be available for use by other state agencies, municipalities, quasi-public and not-for-profits when fully implemented. Contracts and solicitations with the entities mentioned above will remain on BizNet and be migrated at a later date. In addition, the Prequalification Program, Supplier Diversity Program and Surplus Program will continue to operate using BizNet at the current time. Please click here to access BizNet.
