How to do business with the Connecticut government

Connecticut spends billions a year on goods, services, and construction, and a chunk of that is reserved by law for small and minority-owned businesses. If you run a small, minority-, women-, veteran-, or disability-owned business in the state, two systems decide whether you ever see that money. One is CTsource, the state's eProcurement portal, where you register and bid. The other is the Department of Administrative Services supplier-diversity certification, which is what unlocks the set-aside.

You can do the first without the second. But skipping certification means competing for the open market while leaving a 25% reserved lane on the table. Here's the order to do it in, and what each step actually gets you.

Start with CTsource

CTsource is the State of Connecticut's web-based procurement system, run by the Department of Administrative Services (DAS). It's the one-stop site to register as a vendor, search solicitations, and submit bids. Every state agency posts through it.

A few things worth knowing before you sign up:

• Viewing is open; bidding is not. You can browse the CTsource Bid Board and see open solicitations without an account. To respond to one, you need a registered supplier profile.
• Registration is free. The state does not charge to register or to bid. If a site implies otherwise, it isn't the state.
• You register your business profile, not just yourself. That means your legal business name, address, contacts, the commodity codes that describe what you sell, and supporting documentation attached to the account.

Create your supplier account at the CTsource portal, build out your profile completely, and select the commodity or service codes that match your work. Those codes are how buyers find you and how the system routes notifications, so don't rush them. An incomplete profile is the most common reason a registered vendor never hears about a relevant bid.

DAS runs a Procurement Division help line for CTsource at 860-713-5095 and DAS.CTsource@ct.gov. Use it. The portal has a learning curve, and the people answering that line do this all day.

Get SBE/MBE certified through DAS

This is the step that changes your odds. Connecticut runs a Supplier Diversity Program, historically called the Set-Aside Program, administered by DAS. It certifies two overlapping categories:

• SBE (Small Business Enterprise): a Connecticut-based, independent small business.
• MBE (Minority Business Enterprise): an SBE that is also at least 51% owned and controlled by a minority person. Under Connecticut statute (C.G.S. 32-9n), "minority" includes members of racial and ethnic minorities, women, and people with a disability. That's the detail most owners miss. A woman-owned firm and a disability-owned firm both certify as MBE here, not just racial and ethnic minority firms.

MBE is a subset of SBE. You certify as SBE first, then layer MBE on top if you qualify. Many owners hold both designations on one application.

Who's eligible

The core requirements, per the DAS eligibility rules:

• A principal place of business in Connecticut. This is an in-state program. Out-of-state firms don't qualify.
• Independence. Your business can't depend on another company for personnel, facilities, equipment, financing, or bonding. The state is screening out pass-through and front arrangements.
• Small. DAS ties size to your federal small-business status, so you register in SAM.gov first and your primary NAICS code determines whether you read as small. There's also a gross-revenue ceiling. DAS materials cite a $20 million ceiling for nonprofits; some program documents reference a lower for-profit figure averaged over three fiscal years, so confirm your exact number with DAS before you assume you're in or out.
• For MBE, ownership and control. The minority owner or owners must hold at least 51%, run daily operations, and receive the economic benefit. Ownership on paper isn't enough; you have to actually run the company.

How to apply

Three moving parts, in order:

1. Register in SAM.gov. DAS pulls your small-business status from the federal SAM database, so you need an active SAM registration before certification. If you haven't done this, it's free and it's the federal on-ramp anyway. Our state programs hub and the SAM walkthrough cover it.
2. Submit the application through Connecticut's CT Gateway system. This is where you upload ownership documents, tax records, and proof of the criteria above.
3. Complete the DAS review. Staff verify ownership, control, residency, and size. Expect to answer follow-up questions and supply additional documents.

Certification isn't instant. Build in several weeks from a clean application to an approval, longer if your documents need back-and-forth. Start before you find a bid you want, not after.

What certification actually unlocks: the 25% set-aside

Here's the payoff. Connecticut's set-aside law (C.G.S. 4a-60g) requires state agencies to direct 25% of procurable contract dollars to certified SBEs. And of that 25%, a quarter (so 6.25% of the total) must go to certified MBEs.

Read that again, because it's the whole reason to certify. A meaningful share of state spending is legally reserved for certified small and minority firms, and uncertified businesses can't touch it. Set-aside solicitations on CTsource are flagged for SBE and MBE bidders only. Certification is the key that opens that door.

If the set-aside concept is new to you, it works on the same logic as federal reserved contracting, which we break down in federal set-asides explained. The state version is narrower and Connecticut-specific, but the idea is identical: take a slice of public spending off the open market and reserve it for businesses that would otherwise lose to scale.

One important change to watch. Public Act 25-75, passed in 2025, is set to convert the fixed 25%/6.25% set-aside into annual spending-allocation goals tied to industry data and periodic disparity studies, with an effective date of July 1, 2026. The reserved-spending intent stays, but the mechanics may shift from a flat percentage to data-driven goals. Confirm the current rules on the DAS site before you build a bid strategy around a specific number.

Where to find the work

• The CTsource Bid Board is the official, current list of state solicitations. Check it on a schedule, and set your profile's commodity codes so relevant bids surface.
• Set-aside solicitations are marked for SBE/MBE bidders. Once you're certified, these are your highest-probability targets because the competition pool is restricted to certified firms.
• Quasi-public and municipal buyers run their own programs. Cities, transit authorities, and entities like the Metropolitan District Commission have small- and local-business programs that sometimes recognize state certification. Worth a look once your state certification is in hand.

A realistic first 60 days

1. Week 1: Confirm or complete your SAM.gov registration and pin down your primary NAICS code and size standard.
2. Week 1-2: Create your CTsource supplier profile, fill it out fully, and select accurate commodity codes.
3. Week 2-3: Start your SBE (and MBE, if eligible) application through CT Gateway. Gather ownership documents, tax returns, and proof of Connecticut residency before you begin so the upload step doesn't stall.
4. Weeks 3-8: Respond to DAS review questions promptly while you watch the Bid Board. You can bid on open-market solicitations before certification lands.
5. On approval: Filter CTsource for set-aside opportunities and put your certification number on every bid and capability statement.

The honest version

Doing business with Connecticut is two registrations and one certification, none of which cost money and all of which take patience. The state isn't going to call you. You have to be registered, certified, and watching the Bid Board for the right solicitation, then bid clean and on time. Owners who treat certification as a one-time errand and then disappear don't win. Owners who keep a current profile, monitor set-aside bids, and respond fast do.

If you'd rather not assemble the same ownership documents three times across SAM, CT Gateway, and any federal certifications you're after, CertifyAll captures your business information once and files your state and federal certifications for you, so the Connecticut SBE/MBE application is generated and submitted alongside the rest instead of being its own separate slog. And once you're certified, listing your firm in our supplier directory puts you in front of corporate and public buyers searching for diverse vendors beyond the state portal.
