Government contracts for service businesses: how to qualify and win

Government agencies buy the same services homeowners and property managers buy: mowing, snow removal, janitorial work, pest control, pressure washing, painting, HVAC and plumbing repair, roofing and more. The difference is how they buy. Purchases follow written rules, the paperwork comes before the work, and the buyer usually has to explain its choice in the file. For an owner-operator, that can be good news. The rules are published, and a small company that follows them closely can compete with bigger ones.

This guide covers federal registration and the SBA programs from their official sources, then how state and local buying differs. It is general information, not legal advice. Federal rules change, and state and local procurement rules vary by state, county, city and agency, so check the current rules for any contract you pursue.

Which government buyers fit a small service company?

Think in layers, starting closest to home:

• Local government. Cities, townships, counties, school districts, park districts, library boards, public housing authorities and water or sewer authorities all maintain buildings and grounds. Their own crews can't cover everything, and some of what they hire out is the kind of recurring work small companies handle well.
• State agencies. State offices, universities, highway rest areas and facilities buy through the state's procurement office or the agency itself.
• Federal agencies. Federal buildings, military installations, national parks, VA facilities and other sites buy services under the Federal Acquisition Regulation (FAR), and proposed contracts above a set dollar level are posted on SAM.gov.
• Prime contractors. Large companies holding federal contracts may need local subcontractors, and the SBA notes that some contracts require the prime to follow a small business subcontracting plan. You work for the prime instead of the agency, which makes it a gentler first step.

The registration and SBA programs below apply to federal work. Local governments run their own vendor lists and bid processes, covered later in this guide.

Is government work worth it for a small company?

Go in with clear eyes. The SBA's own contracting guide says some businesses spend between $80,000 and $130,000 to earn their first contract, and that it could take up to two years to start seeing a return on that investment (as published on SBA.gov when we read it in October 2026). The same page advises keeping a diverse list of private-sector clients to offset early losses, and notes that working with the Department of Defense means invoicing and receiving payments electronically.

That cost is mostly time: learning the rules, writing proposals, waiting on awards and building a record. It is easier to justify when:

• you already do recurring commercial work and have the crew, equipment and insurance to take on a contract site without stalling your other customers;
• there are government facilities within your normal service area, so the work fits your routes;
• you have enough cash to carry payroll while invoices are processed;
• you can keep clean records of every visit, because past performance counts when the next award is decided.

If those don't describe you yet, start with a subcontract or a small local bid. The skills carry over.

How do you register in SAM.gov?

The System for Award Management (SAM.gov) is where businesses register to do business with the federal government. The SBA says you must register there to participate in government contracting, and you receive your Unique Entity ID (UEI), a 12-character alphanumeric value, when you register. The UEI replaced the DUNS number businesses used to get from a third-party website.

It costs nothing. The GSA's entity registration checklist says getting a UEI, registering and keeping your registration active on SAM.gov are all free. The GSA's registration page adds that you do not need to pay a third party to complete it. A company that charges a fee to register you is an optional middleman, and you still answer for every entry in the record.

Gather this before you start, per the checklist:

• legal business name and physical address (a post office box can't be your physical address), plus your date and state of incorporation;
• your taxpayer identification number and an IRS consent form;
• bank account and routing numbers for electronic funds transfer, so you can be paid, plus a yes or no on whether you accept credit cards;
• the NAICS codes for your services (see the next section);
• points of contact, your answers to the representations and certifications, and the SBA supplemental page if you are a small business.

Two settings matter later. The checklist notes that you can choose whether your record appears in public search; if you hide it, state and local governments and other non-federal users searching SAM.gov won't see you. And SAM.gov says you must renew your registration every 365 days to keep it active. Put the renewal date in your calendar the day you finish.

How do NAICS codes and size standards work?

A North American Industry Classification System (NAICS) code describes what your business sells. You pick codes in SAM.gov, the SBA assigns a size standard to each code, and under FAR 19.102 contracting officers generally assign one NAICS code and its size standard to each solicitation. To compete for a small business set-aside, your company, counted together with its affiliates, must be at or under the size standard for the code on that solicitation.

The SBA says most non-manufacturing businesses with average annual receipts under $7.5 million qualify as small, with exceptions by industry, and that for federal contracting, receipts are averaged over your latest five complete fiscal years. Several service industries have higher limits. These are from the SBA's size standards table in 13 CFR 121.201, as shown in the eCFR in October 2026 (the table was last amended in 2023):

Look up the official definition of each code on the Census Bureau's NAICS site before you choose, because the title alone can mislead. The SBA also offers a size standards tool, linked from its contracting guide, that checks a code against your numbers.

How do federal agencies buy services?

The FAR sets dollar thresholds that change how a purchase is made. As listed in FAR 2.101 on Acquisition.gov in October 2026 (FAC 2026-01, effective March 13, 2026):

• The micro-purchase threshold is generally $15,000, but it is $2,500 for services covered by the Service Contract Labor Standards and $2,000 for construction covered by the Davis-Bacon wage rules. Under FAR 13.201, the government purchase card is the preferred way to buy and pay for micro-purchases. If you want small one-off jobs at a federal site, be ready to take a card.
• The simplified acquisition threshold is generally $350,000. Under FAR 19.502-2, purchases of supplies or services above the micro-purchase threshold and up to that amount must be set aside for small business, unless the contracting officer doesn't expect offers from two or more responsible small businesses that are competitive on fair market prices, quality and delivery. Above it, the same two-small-business test, often called the rule of two, decides whether a set-aside is required.
• Publicizing. FAR 5.101 requires contracting officers to synopsize proposed contract actions expected to exceed $25,000 on the governmentwide point of entry, which is SAM.gov. Actions between $20,000 and $25,000 must be displayed in a public place or by appropriate electronic means. Below $20,000 the section requires no public notice at all, which is one more reason to introduce yourself to the contracting office at federal sites near you.

Above the micro-purchase level, agencies may use simplified procedures, sealed bidding, where price and price-related factors decide, or negotiated proposals, where the agency may weigh past performance and approach against price. Our guide on how to bid commercial jobs explains both and how to price them.

One caution: the FAR is being rewritten under the Revolutionary FAR Overhaul. Agencies began using rewritten parts through temporary class deviations in 2025, and OMB published the first formal proposed rules in June 2026. The rewritten text renumbers many sections. In the overhauled Part 19, for example, the rule of two sits at 19.104-1. Always work from the clauses in the solicitation in front of you.

Which SBA programs might you qualify for?

The SBA says the federal government aims to award at least 23% of all federal contracting dollars to small businesses each year, and it reserves some contracts for firms in specific programs. You apply for SBA certifications through SBA Certifications at certifications.sba.gov. Summarized from the SBA's certifications page and veterans page, as read in October 2026:

Program rules and eligibility tests change, so read the SBA's current pages before you apply. The SBA's Mentor-Protege program is also worth a look if an experienced government contractor in your trade is willing to mentor you.

What labor and subcontracting rules come with the contract?

Two federal wage laws change how you price labor on government work:

• The McNamara-O'Hara Service Contract Act, the Department of Labor says, requires contractors and subcontractors performing services on prime contracts over $2,500 to pay service employees at least the wage and fringe benefit rates that prevail where the work is done. The DOL issues a wage determination for each contract, and it becomes part of the contract.
• The Davis-Bacon and Related Acts apply to federally funded or assisted construction contracts over $2,000, including painting and decorating, and require paying laborers and mechanics no less than locally prevailing wages and fringe benefits.

Read the wage determination before you price, not after you win. If it requires a higher rate or benefits than you pay today, that cost belongs in the bid, along with office time for payroll paperwork. The DOL's Davis-Bacon fact sheet says covered contractors must pay workers weekly and submit weekly certified payroll records to the contracting agency, and its Service Contract Act fact sheet lists failing to keep separate records of contract and non-contract hours among common violations. State prevailing wage laws are a separate layer for state and local public construction. The DOL keeps a table of them, last updated in January 2023 when we checked, so confirm current rules with the state agency.

Set-aside contracts also limit how much you can hand off. Under 13 CFR 125.6, on a small business set-aside for services worth more than the simplified acquisition threshold, and on 8(a), HUBZone, SDVOSB and WOSB contracts, the small business prime agrees not to pay more than 50% of what the government pays it to subcontractors that are not similarly situated. On contracts for special trade contractors, such as roofing or painting work, the limit is 75%, and the cost of materials is left out of the count. You can't win a set-aside and pass the whole job to a large company.

Where do you find government opportunities?

• SAM.gov Contract Opportunities. Search by your NAICS codes and your state, and check on a set schedule so you see notices before the response deadline.
• Award history. The SBA points to the Federal Procurement Data System, which holds data on contracts over $25,000, and to USAspending.gov. Look up who holds the current contract at a site near you, what it was worth and when it ends. A contract that ends next year may be competed again.
• Agency procurement forecasts. The SBA notes that each agency publishes a forecast of upcoming opportunities for small businesses.
• Subcontracting. The SBA's subcontracting page lists SUBNet, where large businesses post subcontracting opportunities, and an SBA directory listing primes that carry subcontracting plans. Primes also search the SBA's Small Business Search (SBS), so the SBA advises completing your SBS profile with a capabilities narrative, keywords, NAICS codes and performance history.
• Local help. The SBA points small businesses to APEX Accelerators, formerly Procurement Technical Assistance Centers, for help finding subcontracting opportunities.

Expect buyers to look you up. Add a page to your website for government and commercial buyers that lists your UEI, CAGE code, NAICS codes, any SBA certifications, your service area, your insurance and a few documented examples of similar work. It doubles as your capability statement and as the profile text for SBS.

How do state and local governments buy?

Each state, and often each county, city and school district, sets its own purchasing rules: dollar levels for informal quotes versus formal sealed bids, vendor registration, insurance minimums, bonding, prevailing wage, local preference and payment timing. Those rules vary widely, so we won't summarize any one state here. These steps work almost anywhere:

1. Find the purchasing or procurement page for each public body in your service area and register as a vendor in the categories you serve.
2. Learn where it posts bids (its own website, a state portal or a bid service) and set alerts.
3. Ask the purchasing office where its line sits between informal quotes and formal bids, and who can approve small jobs. Small, informal purchases are a realistic first public job.
4. Attend pre-bid meetings for work you want, even if you don't bid that round. You meet the facilities staff who write the next scope.
5. Read public bid results. Seeing who won and at what price is the cheapest market research you will get.

How and when does the government pay?

Federal payment timing follows the Prompt Payment rules in the FAR. Under FAR 32.904, the standard due date for an invoice payment is the later of the 30th day after the designated billing office receives a proper invoice or the 30th day after the government accepts the services. Under FAR 32.907, when the government pays late on a proper invoice and there was no disagreement over the work, the payment office adds an interest penalty automatically, without a request from you. The key word is proper. FAR 32.905 lists what a proper invoice must include, such as the contract number, a description of the services, your taxpayer ID and your banking details, and says a billing office that finds an invoice improper must return it within 7 days with the reasons. The 30 days run from receipt of an invoice that meets the list.

State and local payment terms are set by each government's own rules and contract. Ask before you bid, and price the wait into the job.

Records do double duty here. Visit logs, timestamped photos and signed tickets support your invoices and become the past performance you cite on the next proposal. A custom CRM can keep those records on each contract along with the renewal date for your SAM.gov registration and the expiration dates on your insurance.

A practical first-year plan

1. Register in SAM.gov directly, for free, and set a renewal reminder.
2. Choose your NAICS codes and confirm your size against the SBA table.
3. Check whether any SBA certification fits your ownership or location, and apply if it does.
4. Build your government buyer page and a one-page capability statement, and complete your SBS profile.
5. Register as a vendor with the local public bodies in your service area.
6. Bid small local jobs and pursue a subcontract near a federal site to build a record.
7. Track every bid, award and loss, and keep documented proof of every visit on every public job.
