How to register, step by step
- 01
Register on CTsource supplier registration
Start registration. Cost: No fee listed by the State of Connecticut. Soft registration is a short web form that gives immediate access to view solicitations; full registration means logging in to upload company documents such as an IRS W-9, affidavits and insurance certificates. Select UNSPSC codes to receive solicitation notices.[2]
- 02
Have your W-9, affidavits and insurance certificates
Full CTsource registration requires uploading these company documents.[2]
- 03
Choose your commodity codes
Notifications are sent by the codes in your vendor profile. Pick every code that describes your work, and revisit them when you add a service.
- 04
Get certified if you qualify
Small Business Enterprise (SBE) / Minority Business Enterprise (MBE) Certification, through the Connecticut Department of Administrative Services. Business must have its principal place of business in Connecticut and be registered as small in SAM; MBE adds 51% ownership by a person with minority status under state law.[3]
- 05
Watch the other buyers
Cities, counties and authorities in Connecticut post on their own sites, so check the ones you want to sell to.
What you will typically need
Exact requirements vary by portal; the registration page linked above is the authority. Most ask for:
- Your legal business name and address exactly as registered with the state, and your federal tax ID (EIN, or SSN for some sole proprietors).
- A signed IRS Form W-9, which most buyers collect before they can pay you.
- Commodity codes (NIGP, UNSPSC or NAICS, depending on the portal) for every product and service you sell.
- A contact who will receive bid notices, plus any business license or registration the jurisdiction requires.
- Certificates of insurance and, for construction, bonding capacity: these are usually requested per bid rather than at registration.
