How to register to bid on government contracts (and what you can skip)

There is no single registration

New bidders often ask where to "register for government contracts" as if there were one list. There is not. The federal government has one system. Each state has its own. Many cities, counties, school districts and authorities have theirs. You register with the buyers you actually intend to bid to, and nobody else. Registering everywhere is a week of forms that wins nothing.

The useful order is the reverse of what most people do: find a bid you would really go after, read which registration that notice requires, and do that one. You can read open notices without registering anywhere - on the agency's own site, or collected on BusyBids.

Federal work: SAM.gov, and it is free

To be awarded a federal prime contract your business has to be registered in the System for Award Management, SAM.gov. The SBA lists it among the basic requirements for federal contracting. Registration assigns your Unique Entity ID, a 12-character identifier that you will be asked for on federal forms. If a form only asks for the ID, SAM can issue one from your legal business name and physical address without the full registration.

Three things about SAM catch people out:

• It costs nothing. The General Services Administration, which runs SAM, puts it plainly: "Registration in SAM.gov is always free", and "The government will never ask you to pay to register, update your registration, or renew." Companies that charge to file it for you are selling a convenience, not a requirement. An email saying your registration has a problem and asking for a fee is not from SAM. Sign in at SAM.gov yourself and look.
• It is not instant. Your details are checked against other federal records before the registration goes active, and a mismatch in your legal name or address sends it back. Start weeks before the first federal bid you want, not the week it is due.
• It expires. SAM says you must renew every 365 days to keep the registration active. Put the date in a calendar. An agency cannot award a contract to a firm whose registration is not active, and reactivating one takes the same checks as the first time.

Before you start, have your legal business name exactly as it appears on your tax filings, your taxpayer identification number, your bank details for payment, and the NAICS codes that describe your work. NAICS is the industry classification the government uses to describe a purchase and to decide whether a business counts as small for it. You pick a primary code and can add others.

State work: the state's own vendor system

Each state runs its own procurement and its own vendor registration, and the rules differ. Some charge a fee and some do not. In Texas, for example, the Comptroller's Centralized Master Bidders List has a $70 annual registration fee and is what state buyers use to send out bid notices. Other states register vendors inside the same portal where bids are posted. The state's procurement office page will say which, and the notice itself names the system you must be in to respond.

Local work: check the notice, not a list

Cities, counties, school districts, water districts and transit authorities buy the work most small contractors actually do: mowing, janitorial, roofing repairs, paving, HVAC service. They are also the least uniform. Some take sealed paper bids at a clerk's counter and need no registration at all. Some use a commercial bidding portal that needs a free account. Some large cities run a full enrollment that takes weeks; New York City's is covered in our PASSPort guide.

What a local notice asks for is usually on its first two pages: where bids go, in what form, by what time, and which accounts or forms the bidder needs first. Read that before anything else.

What to have ready everywhere

Whatever the system, the same handful of documents is asked for again and again. Keep current copies in one folder:

• Your legal business name, tax identification number and business address, written the same way every time.
• A completed W-9.
• Your certificate of insurance, and your agent's contact for adding a buyer as certificate holder.
• Trade licenses, with numbers and expiry dates.
• Your state or local business registration.
• Two or three references for similar work, with current phone numbers.

What registration does not do

Being registered makes you able to bid. It does not send work your way, and it says nothing about whether you meet the requirements of a particular bid. Some systems email notices to registered vendors and many do not, or only for the product codes you chose. The notice is always the authority on who may bid and what must be submitted. When registration and a deadline are both in play, the registration is the one to start today.
