How to Find Government Contracts: Where Opportunities Are Posted, How to Register, and How to Win Them

If you want to know how to find government contracts, start with three free sources: SAM.gov Contract Opportunities for federal solicitations, USAspending.gov for past awards that show who buys what, and your state and city procurement portals for local bids. Register your business in SAM.gov to get a Unique Entity ID, pick the right NAICS codes, and then stop waiting for bids alone. The firms that win most often also talk directly to contracting officers, prime contractors and small business offices before a solicitation ever appears.

This article walks through each source, the registration steps, the SBA small business programs, the document types you will see, and how outbound prospecting with verified contact data turns a list of opportunities into a real B2G sales pipeline.

What does B2G sales mean, and why is it different from B2B?

B2G (business to government) sales means selling products or services to federal, state or local government agencies. The buyer is a public body that spends taxpayer money, so the process is governed by rules rather than by one executive’s preference.

That changes three things compared with a normal B2B deal:

• Process is formal. Federal purchases follow the Federal Acquisition Regulation (FAR), and states and cities have their own procurement codes.
• Timing is public. Most opportunities are announced, have a deadline and are scored against published criteria.
• Relationships still matter. Rules limit what you can say during an open solicitation, but agencies actively want to meet capable vendors before they write requirements.

If you already sell to businesses, many of your skills carry over. Our B2B prospecting guide covers the research and outreach habits that also work for public sector buyers.

Where are government contract opportunities posted?

Opportunities are spread across federal, state and local systems. Knowing which system covers which buyer saves hours of random searching.

Federal: SAM.gov Contract Opportunities

SAM.gov is the official US government system for federal contract opportunities. It replaced the old FedBizOpps (FBO.gov) site. You can search without an account, then save searches and set email alerts once you sign in.

Useful filters on SAM.gov include:

• Keyword, such as “janitorial services” or “cybersecurity assessment”.
• NAICS code and Product Service Code (PSC).
• Notice type, such as sources sought, presolicitation, solicitation or award notice.
• Set-aside, such as total small business, 8(a), HUBZone, WOSB or SDVOSB.
• Place of performance and agency.

Past awards: USAspending.gov

USAspending.gov is the official source for federal spending data, including contract awards. It does not list open bids, but it answers questions that SAM.gov cannot: which agencies bought your type of service, how much they spent, which companies won, and when contracts are likely to expire and be recompeted.

That makes it your best research tool for targeting. A recompete you spot 12 months early is far easier to win than a solicitation you discover two weeks before it closes.

State and local procurement portals

Every state runs its own procurement website, and many counties, cities, school districts and transit authorities post bids separately. Search for “[your state] procurement portal” or “[your city] bid opportunities”, register as a vendor on each one that matters to you, and turn on commodity code alerts.

Local buying often moves faster and involves smaller contracts, which makes it a practical starting point for new contractors. For a state level example, see our article on B2G marketing strategies in California.

Subcontracting and other sources

• SBA SubNet lists subcontracting opportunities posted by prime contractors.
• GSA schedules let agencies buy from pre-approved vendors, so getting on a schedule can open steady demand.
• Agency procurement forecasts show planned purchases for the coming fiscal year.
• Prime contractor supplier portals let large primes register small subcontractors.

Source	What you find there	Best used for	Cost

Paid bid aggregators	Federal, state and local bids in one feed	Saving search time at scale	Subscription

How do you register to bid on government contracts?

You can search opportunities without registering, but you cannot receive a federal award until your entity registration is active. Follow these steps in order.

1. Form your legal business. Have your legal name, physical address and taxpayer identification number (EIN) ready, and make sure they match IRS records exactly.
2. Create a Login.gov account and sign in to SAM.gov with it.
3. Register your entity in SAM.gov. The registration is free. SAM.gov assigns your Unique Entity ID (UEI), the 12 character identifier that replaced the DUNS number in April 2022.
4. Choose your NAICS codes. NAICS codes classify what your business does, and SBA size standards are set per NAICS code, which decides whether you count as small for a given contract.
5. Complete representations and certifications, including your small business status for each NAICS code.
6. Get a CAGE code. It is assigned as part of the SAM.gov registration process for US entities.
7. Renew every year. SAM.gov registrations must be renewed annually, and a lapsed registration can cost you an award.
8. Build your SBA profile so contracting officers and primes searching for small businesses can find you.

Be careful with third parties that charge to “register” you. SAM.gov registration itself costs nothing, and free help is available from SBA resources and APEX Accelerators (formerly called Procurement Technical Assistance Centers).

Which SBA programs help small businesses win government contracts?

The federal government sets a statutory goal of awarding at least 23 percent of prime contract dollars to small businesses. To meet that goal, agencies set aside many contracts for small firms, and some for specific groups. The SBA federal contracting pages explain each program in detail.

Program	Who it is for	Key point
8(a) Business Development	Small businesses owned by socially and economically disadvantaged individuals	A nine-year program that includes set-asides, sole-source awards and mentoring
HUBZone	Small businesses in Historically Underutilized Business Zones	Principal office in a HUBZone and at least 35 percent of employees living in one
WOSB / EDWOSB	Women-owned small businesses	At least 51 percent owned and controlled by women; certification through SBA
SDVOSB	Service-disabled veteran-owned small businesses	Certified by SBA since 2023 for federal set-asides
Small business set-aside	Any firm that meets the size standard for the NAICS code	The broadest door into federal work

Certification does not bring work by itself. It makes you eligible for a smaller pool of competitors, and it gives you a reason to start conversations with agencies that need to meet their goals.

How do you read sources sought, RFI, RFP and RFQ notices?

Each notice type tells you where the buyer is in the process. The earlier you engage, the more influence you have.

Notice	What it means	What you should do
Sources sought	Market research: the agency wants to know who can do the work	Always respond if you fit. Responses can lead the agency to set the contract aside for small businesses.
RFI (request for information)	The agency is gathering input on requirements or approach	Share relevant capability and practical suggestions
Presolicitation	A solicitation is coming soon	Prepare your team, pricing and teaming partners
RFP (request for proposal)	Formal solicitation scored on technical approach, past performance and price	Answer every evaluation factor in the order the RFP asks
RFQ (request for quotation)	Simpler buy, often decided mainly on price	Quote fast, accurately and in the required format
IFB (invitation for bid)	Sealed bidding, usually lowest responsive and responsible bid wins	Follow every instruction exactly

Our article on B2G opportunity targeting goes deeper into qualifying which of these notices deserve a bid and which you should skip.

How can small businesses find government contracts through teaming and subcontracting?

Most new contractors lack federal past performance, and many RFPs score it heavily. Subcontracting solves that problem. You deliver part of a larger contract, earn revenue and build the track record you need to prime later.

Ways to get there:

• Find primes on USAspending.gov that have won contracts in your NAICS code, then contact their small business liaison officers.
• Form teaming agreements where a prime and a subcontractor bid together on a specific opportunity.
• Consider joint ventures with another small business, or the SBA mentor-protege program, when a contract needs capability you lack alone.
• Respond to SubNet postings and register on prime supplier portals.

Large primes often have their own small business subcontracting goals, so a well-targeted small firm is a welcome contact, not an interruption.

How does outbound prospecting help you win government contracts?

Here is the part most guides on how to find government contracts leave out. Portals show you what is already public. By the time an RFP posts, the strongest bidders have usually met the program office, answered the sources sought notice and lined up teaming partners. Outbound prospecting is how you get into that earlier conversation.

Who should you contact in B2G sales?

• Contracting officers and contract specialists. They manage the acquisition. Their names appear on SAM.gov notices and past awards.
• Program managers and end users. They define the requirement and care about outcomes.
• OSDBU offices. Each federal agency has an Office of Small and Disadvantaged Business Utilization (called the Office of Small Business Programs at the Department of Defense). Its staff help small businesses understand the agency’s buying.
• Prime contractor small business liaisons and capture managers. They choose subcontractors and teaming partners.
• State and local procurement officers and department heads for non-federal work.

One important rule: once a solicitation is open, communicate only through the point of contact named in the notice, and follow its instructions. Relationship building belongs before release and between opportunities.

Why does verified contact data matter?

Government domains and large primes run strict mail filtering. Sending to guessed or outdated addresses causes bounces that damage your sender reputation and can push your messages to spam for everyone else too. Before any campaign:

• Use the free LeadCanal email finder to find the work email of a prime’s capture manager or small business liaison.
• Use the LinkedIn contact finder to turn a LinkedIn profile into a business contact.
• Run every address through the email verifier to remove invalid and risky emails.
• Use company lookup to check a prime contractor’s size, industry and domain before you pitch a teaming arrangement.

A step-by-step plan for a B2G prospecting campaign

1. Define your target. Pick two to four NAICS codes and the agencies that buy them most, based on USAspending.gov data.
2. List the recompetes. Note contracts ending in the next 12 to 24 months, the incumbent and the contracting office.
3. Map the people. For each target, list the contracting office, the OSDBU contact, the program office and two or three primes active in that space.
4. Find and verify emails. Use the email finder and verifier, and drop anything you cannot confirm.
5. Write a capability statement. One page: core competencies, past performance, differentiators, NAICS codes, UEI, CAGE code and certifications.
6. Send short, specific emails. Reference a real contract, a sources sought notice or a known agency mission. Ask for a 15 minute capability briefing, not a sale.
7. Follow up on LinkedIn and at industry days. Agency outreach events and small business conferences are designed for these introductions.
8. Track every touch. Log contacts, responses and upcoming notices in a CRM so nothing slips when the RFP finally posts.

Keep outreach honest and compliant. Identify your company clearly, make every claim accurate and offer an easy opt-out. The FTC’s CAN-SPAM compliance guide covers the commercial email basics.

Your credibility also depends on how your firm presents itself once a buyer clicks through. Our article on government contractor branding shows how to make your website and capability statement build trust.

What mistakes stop new contractors from winning?

• Bidding on everything. Unqualified bids waste time. Bid where you meet the requirements and can show relevant experience.
• Ignoring sources sought notices. They are your best chance to shape a set-aside.
• Letting SAM.gov registration lapse. Set a renewal reminder well before expiry.
• Choosing too many NAICS codes. A focused profile is easier for buyers to understand.
• Waiting for the RFP to start selling. By then, buyers have already met your competitors.
• Using unverified contact lists. Bounces hurt your domain reputation and your first impression.

Frequently asked questions

How do I find government contracts to bid on?

Search SAM.gov Contract Opportunities for federal bids using your NAICS codes and set-aside filters, and register on your state and city procurement portals for local bids. Save searches and turn on email alerts so new notices reach you automatically.

Is SAM.gov registration free?

Yes. Registering your entity in SAM.gov and getting a Unique Entity ID costs nothing. Free help is available from SBA resources and APEX Accelerators, so you do not need to pay a third party.

How do I find government contracts that have been awarded?

Use USAspending.gov to search federal contract awards by agency, recipient, NAICS code and location. SAM.gov also shows award notices for many opportunities.

How can a small business get its first government contract?

Start with smaller buys, local government bids and subcontracts under primes. Respond to sources sought notices, apply for SBA certifications you qualify for and build relationships with OSDBU offices to gain past performance.

What is the difference between an RFP and an RFQ?

An RFP asks for a full proposal that is evaluated on factors such as technical approach, past performance and price. An RFQ asks for a price quote and is usually used for simpler purchases.

Can I contact a contracting officer directly?

Yes, before a solicitation is released, and many agencies welcome capability briefings. Once a solicitation is open, communicate only through the point of contact named in it.

What is B2G sales?

B2G sales means selling products or services to government agencies at the federal, state or local level. It follows formal procurement rules, but research and relationship building still decide many wins.

Are government contract records public?

Federal contract award data is published on USAspending.gov, and many state and local governments publish award results on their procurement sites.
