Winning a government contract on your own the first time out is hard. You are up against companies with long records, dedicated proposal staff, and contracting officers who already know their names.
Subcontracting is the side door. You do part of the work under a company that already holds the contract, called the prime. You get paid, you learn how government work actually runs, and you build the experience you will need when you go after contracts yourself.
Here is how to find that work.
Why primes need small businesses
This is the part most people miss. When you reach out to a prime, you are not begging. Many of them have a real reason to want you.
- Subcontracting plans. Under federal law, some larger federal contracts require the prime contractor to submit a small business subcontracting plan with goals for how much work goes to small businesses, and to report progress against it. The details and dollar thresholds are set in the contract and the regulations, but the effect is the same: those primes have to find small business partners.
- Skills they do not have. A big firm that won a facilities contract may not have a trainer, a notary, a translator, or a local crew in your city.
- Certifications that help them compete. If a contract evaluates small business participation, a prime may bring on a woman-owned or other certified small business to strengthen its proposal. Only claim certifications you actually hold today.
Lead with how you fill one of those gaps.
Step 1: Get your basics in order
Before you contact anyone, have these ready:
- A SAM.gov registration. Not every subcontractor is required to have one, but many primes ask for it, and it is free. Never pay a company that says you must pay to register.
- Your NAICS codes. Know which codes describe your work. Primes and agencies search by them.
- A one-page capability statement that says what you do, who you have done it for, and how to reach you. See writing a capability statement that gets read.
- Proof you can deliver. Insurance, licenses for your trade, and a short list of real work you have done, government or not.
Step 2: Find the primes who need what you do
SBA SubNet. The Small Business Administration runs the Subcontracting Network, where prime contractors post subcontracting opportunities. Search it for your NAICS codes and check it regularly.
USASpending.gov. This is the public record of federal awards. Search for the kind of work you do and the agencies you want to work with, and you will see which companies are winning those contracts. Those companies are your prime list.
Supplier portals. Most large contractors have a supplier diversity or small business page on their own website, usually with a vendor registration form. Register with the ones from your list. It will not get you work by itself, but it gets you into their system.
State and local buyers. Cities, counties, transit authorities, and school districts often publish who won their contracts and sometimes host meetings where primes meet subcontractors. Check the purchasing page of every agency you want to work with.
Pre-proposal conferences and industry days. When an agency holds one, primes show up looking for partners. Attendee lists are sometimes posted afterward. Go, listen, and talk to people.
Step 3: Approach them the right way
Find the small business liaison or supplier diversity contact, not a general sales inbox. Then keep the first message short:
- What you do, in one sentence.
- Which of their contracts or upcoming opportunities it fits, by name.
- The gap you fill: a skill, a location, or a certification you hold.
- Your capability statement attached.
Do not send a generic "we would love to partner" email to fifty companies. Ten specific ones will do more.
Timing matters. The best time to join a team is before the proposal is written, when the prime is still deciding who is on it. Once a contract is awarded, the team is usually already set, though primes do sometimes add subcontractors later when needs change.
Step 4: Read the agreements
When a prime is interested, you may be asked to sign a teaming agreement before the proposal goes in, and a subcontract after the award. Read both carefully. Pay attention to:
- What work you are actually guaranteed. A teaming agreement often promises less than it seems to.
- Exclusivity. Some agreements bar you from joining another team bidding on the same contract.
- Payment terms. When you get paid, and whether you get paid only when the prime gets paid.
- Flow-down clauses. Rules from the prime contract that pass down to you.
Have an attorney review these before you sign. This is not legal advice, and contract terms vary widely.
Step 5: Deliver, document, and ask for the reference
Do the work well and on time. Then write down what you did, the contract it was under, the agency, the dates, and your point of contact at the prime. Ask that contact if they will serve as a reference while the work is fresh in their mind.
That record becomes your past performance. If you have been wondering how to write that section with no prime contracts behind you, see how to write past performance when you have never had a government contract.
The honest part
Subcontracting takes patience. Many outreach emails go unanswered, and some teams you join will not win. That is normal. Keep the list current, keep showing up, and keep your materials ready. The businesses that get subcontracting work are usually the ones still reaching out after everyone else stopped.
Questions people ask
How do I find subcontracting opportunities on government contracts?
Start with the SBA's Subcontracting Network, called SubNet, where prime contractors post opportunities. Then look up who has won contracts in your field on USASpending.gov, and check the supplier or small business pages on those companies' own websites. Many large contractors run a vendor registration portal.
Do I need to be registered in SAM.gov to be a subcontractor?
Not always. SAM registration is required to be a prime contractor on federal work, but many primes ask their subcontractors to register too, and some require it. Registration is free on SAM.gov, so it is usually worth doing. Never pay a third party who claims you must pay to register.
Why would a prime contractor want to work with a small business?
Some federal contracts require the prime to have a small business subcontracting plan with goals, and to report on it. Other primes need a skill, a location, or a certification they do not have in house. Either way, you are filling a real gap, not asking for charity.
What is a teaming agreement?
A teaming agreement is a written agreement between a prime and a subcontractor, usually signed before a proposal is submitted, that spells out what each side will do if the contract is won. Read it carefully, and have an attorney review it before you sign, especially any exclusivity terms.
Is subcontracting a good way to build past performance?
Yes. Work you do as a subcontractor on a government contract is real, relevant experience you can describe in later proposals. Keep records of what you did, for whom, and when, and ask the prime for a reference while the work is fresh.
