How do small businesses find government contracts in the US?

Where are federal contract opportunities posted?

The main source is Contract Opportunities on SAM.gov, which holds procurement notices from federal contracting offices, including presolicitation, solicitation, award and sole source notices. Anyone can search it without an account. The Federal Acquisition Regulation (FAR) calls this the Governmentwide point of entry and gives sam.gov as its address.

SAM.gov does not show every federal purchase. The FAR's publicizing rules in Part 5 list exemptions, and the overhauled Part 5 text that many agencies now follow by deviation exempts, among other things, orders under existing task order and delivery order contracts. That work flows to businesses already holding those contracts.

Two other federal sources are worth checking:

• Procurement forecasts. SBA says each agency releases a procurement forecast that includes opportunities for small and disadvantaged businesses. GSA's Forecast of Contracting Opportunities tool on Acquisition Gateway shows forecasts from participating agencies, needs no registration, and can surface work sometimes months before a solicitation appears on SAM.gov. GSA notes that forecasts are for information and planning only and are subject to revision or cancellation.
• GSA's Multiple Award Schedule (MAS), also called schedules or the Federal Supply Schedule. GSA describes it as a long-term contract that allows federal agencies to buy directly from pre-approved vendors, and schedule holders get access to GSA tools such as eBuy. GSA suggests at least 2 years in business unless you use its Startup Springboard option, and states plainly that a Schedule contract doesn't guarantee sales.

What do you need before you can bid on federal work?

SBA's basic requirements start with registering in the System for Award Management at SAM.gov, which SBA describes as a database government agencies search to find contractors. You receive a Unique Entity ID (UEI), a 12-character alphanumeric identifier, through SAM.gov. Registration is free and must be renewed every 365 days.

SAM.gov also offers a UEI without full registration, for entities such as subawardees, but an entity with only a UEI cannot apply directly for federal awards. If you plan to bid as a prime, you need the full registration.

During registration you choose NAICS codes, the standardized codes the government uses to classify industries. A business can have more than one. SBA assigns a size standard to each NAICS code, generally based on number of employees or annual receipts, and its Size Standards Tool shows whether you qualify as small for government contracting. Through SAM, you certify that your business is eligible for contracts reserved for small businesses.

In my experience, the NAICS codes you pick matter twice: they shape your size status, and they are how you will filter SAM.gov and award data later. List every code that genuinely matches your work, not just the first one that seems close.

How do small business set-asides and SBA programs work?

SBA describes two kinds of set-asides. A competitive set-aside reserves a contract for small businesses when at least two of them could do the work. A sole-source set-aside can be issued without a competitive bidding process, usually when only one business can meet the requirements.

Some set-asides are limited to businesses in SBA's contracting programs. SBA lists:

• The 8(a) Business Development program
• The HUBZone program
• The Women-Owned Small Business Federal Contract program
• The Service-Disabled Veteran-Owned Small Business program

SBA says you can self-certify for some programs by updating your profile in SAM, while others require a formal application, so check each program's eligibility rules on SBA's site before you assume you qualify. SBA also runs a Mentor-Protégé program and allows joint ventures that let certain businesses compete together for contracts reserved for small businesses. On SAM.gov, you can filter opportunities by set-aside type.

How do you find subcontracting work with prime contractors?

SBA explains that prime contractors work directly with the government, while subcontractors work for other contractors. That lets a business take part in federal work before it is ready to hold a federal contract itself. Federal contracts awarded to other-than-small businesses above a dollar threshold must include a small business subcontracting plan under FAR 52.219-9, and GSA notes that some large prime contractors must meet small business subcontracting goals. Places to look:

• SUBNet, SBA's subcontracting database, where large businesses post subcontracting opportunities. GSA notes you can search it by keyword, NAICS code, state, metro area, small business type and prime contract name.
• SBA's Directory of Federal Government Prime Contractors with a Subcontracting Plan.
• Agency directories, including GSA's subcontracting directory, which lists other-than-small businesses with GSA contracts that require subcontracting plans, and directories run by DOT and USDA.
• Your Small Business Search (SBS) profile. SBA says primes use SBS to find small businesses, so keep it complete with certifications, a capabilities narrative, keywords, NAICS codes and performance history.
• Award notices on SAM.gov, which show who just received a contract.

SBA also points to APEX Accelerators, formerly Procurement Technical Assistance Centers, for help with readiness, registration, certification eligibility and researching past contract opportunities.

Where do state and local governments post their contracts?

State and local bids are not on SAM.gov, which carries notices from federal contracting offices. Each state runs its own procurement system, and the rules differ. Two examples from official state sources:

• Texas: the Comptroller describes the Electronic State Business Daily (ESBD) as a search for state and local government bids and award notices posted by state agencies and local government co-op members, and sign-in is not required to search it. The Comptroller's Centralized Master Bidders List (CMBL) is used by state purchasing entities to develop a mailing list for vendors to receive bid opportunities.
• New York: the Office of General Services says the New York State Contract Reporter is where all state government bid opportunities are posted, and you can sign up for email notifications about business opportunities.

Local government is more fragmented. In my experience, cities, counties, school districts and special authorities usually run their own purchasing and post on their own websites, on a third-party bid platform they have chosen, or on both, often with a separate vendor registration for each. Some state systems carry part of this work: on the Texas ESBD, I see school districts and cities listed next to state agencies and universities. If you want local work, list the specific agencies you can serve and confirm where each one posts.

How can award data show you who buys what?

Past awards are the best map of future demand. USAspending.gov takes its contract data from the Federal Procurement Data System (FPDS), where federal contracting officials submit transaction-level data, and those records include the awarding agency, recipient, place of performance, NAICS code, product or service code, and type of set-aside. How I use it:

1. Open Advanced Search on USAspending.gov and limit the award type to contracts. Only contract spending carries NAICS codes.
2. Filter by your NAICS or PSC codes.
3. Choose the location filter deliberately. Place of performance is where most of the work is performed, while recipient location is the legal business address of the company that received the award.
4. Note which agencies award this work and which companies receive it. The agencies are your buyers to watch, and the companies are potential primes for subcontracting.
5. Download the results to keep a working list.

Two timing caveats from USAspending's About the Data notes, last updated November 19, 2025: contract data generally appears within five days of an award or modification, but Department of Defense and U.S. Army Corps of Engineers procurement data is published on a 90-day delay in FPDS. SAM.gov also offers contract award data to signed-in users, and SAM.gov says contract award searches that used to run on FPDS.gov's ezSearch should now be done in SAM.gov.

Where do small businesses commonly miss opportunities?

What I see most often is not a lack of opportunities but gaps in where people look:

• Watching SAM.gov only, while state agencies, cities, counties and school districts post elsewhere.
• Ignoring sources sought notices. GSA warns that if capable small businesses do not respond, small businesses may lose a potential set-aside.
• Skipping forecasts, which can show work months before it is solicited.
• Filtering on one NAICS code, when buyers may code similar work differently.
• Letting the SAM.gov registration lapse past the 365-day renewal.
• Overlooking subcontracting, even though award notices and USAspending.gov show which primes just took on work.
• Records that do not match. GSA advises keeping your business name, address and ownership details consistent across IRS, SAM.gov and SBA records.
