How to Sell to the Government: The Complete Guide

The U.S. federal government committed $793 billion on contracts in fiscal 2025. The 50 states buy on top of that: Texas alone spent $35.8 billion on procurement in FY2024, California awarded $15 billion, and New York's reporting agencies spent $10.5 billion. Every dollar of it went to a company that, at some point, was exactly where you are now: unregistered, unranked, and wondering where to start.

This guide is the path from zero to bidding. Each step links to a deeper guide or a free tool, so go as deep as you need.

Step 1: Confirm the government buys what you sell

Before registering anything, spend thirty minutes checking demand. Search SAM.gov Contract Opportunities for your product or service; federal agencies must post nearly every requirement over $25,000 there. Then look up your industry's NAICS code and read its spend profile: our code pages show FY2025 obligations and the top five buying agencies for each, so you can see in one glance whether your market is DoD-heavy, civilian-led, or barely exists.

Two examples of why this matters. Engineering services (541330) carried $52 billion in FY2025. Computer training (611420) carried $201 million. Both are real markets, but they demand different strategies, and knowing your number changes how much you invest in the next steps.

If the readiness assessment tells you nothing else, it tells you whether to keep reading.

Step 2: Register in SAM.gov, and pay no one to do it

SAM.gov is the federal government's vendor system: it issues your Unique Entity ID (the DUNS replacement), assigns your CAGE code, and holds the registration every federal offer legally requires. It is free. GSA states plainly that you never need to pay to register, renew, or fix errors, and an industry of official-looking services charges hundreds of dollars for exactly that. Registration takes up to 10 business days to activate and renews every 365 days.

Selling to states too? Each has its own front door, and the fees are smaller than the folklore suggests: Texas SmartBuy's CMBL costs $70 a year, Cal eProcure and MyFloridaMarketPlace registration are free, and the NYS Contract Reporter is free to search and register. Our portal guides walk each registration step by step.

Step 3: Pick your codes like buyers search them

Your NAICS codes are how government buyers find you, and how set-aside eligibility gets decided. Pick codes that match what you deliver, not what sounds impressive; contracting officers check. The NAICS finder searches all 1,012 codes in plain English with the current SBA size standards.

Then learn the second code system most new vendors miss: PSC codes, which classify what the government buys on each award. The pairing is not obvious. The largest federal application-development code, PSC DA01, pays three times more to systems-design registrations than to custom-programming ones. Reading the crosswalk before you register can put you in the bigger pool.

Step 4: Claim every status you qualify for

The federal government awarded $179 billion in prime contracts to small businesses in FY2025, nearly 28 percent of eligible dollars. A large share of that flows through set-asides: contracts only small businesses can win.

Whether you count as small depends on the SBA size standard for your NAICS code: a revenue cap (often $19M to $47M) or an employee cap, by code. If you qualify for more (8(a), HUBZone, WOSB, or SDVOSB), apply at certifications.sba.gov; every SBA certification is free, and self-certification is gone for most of them (WOSB since 2020, SDVOSB since December 2024). The set-aside calculator maps which programs fit you.

States run their own versions with real teeth: California's certified small businesses get a 5 percent bid preference, and New York can hand certified MWBE and SDVOB firms discretionary purchases up to $1.5 million without competition.

Step 5: Build a pipeline, not a lottery ticket

Winning vendors treat opportunity discovery as a weekly ritual, not a scramble:

1. Save searches where the bids post. One saved search per NAICS code on SAM.gov, plus your state's board: the ESBD in Texas, the CSCR in California, the Contract Reporter in New York.
2. Read awards, not just open bids. Award records name every winner, every price, every buying office. That is your competitor list and your price benchmark, published daily and free.
3. Get a capability statement ready before you need it. One page, your codes, your differentiators, your past performance. The builder produces one in minutes.
4. Go where buyers already know they need you. Agency guides show how each federal buyer works; state guides do the same for all 50 states. If you sell innovation to defense, SBIR is a funded on-ramp designed for first-timers.

Step 6: Win small first, then compound

The first contract is the hardest, and chasing a $10 million IDIQ as an unknown is how new vendors burn a year. The fastest paths run through smaller, quieter lanes: purchases under simplified thresholds, state buys that need only a few informal quotes (Texas requires just three bids between $10,000 and $25,000), subcontracting under an established prime, and set-aside competitions with thin fields.

Every delivered contract becomes past performance, and past performance is what wins the next, bigger award. Agencies rebuy from vendors who delivered. That is the whole compounding loop: register once, build the pipeline, win small, deliver well, and let each award buy the credibility for the next.

The sequence, one week at a time

1. This week: verify demand (Step 1), start your SAM.gov registration, and run the readiness assessment.
2. While SAM processes: pick NAICS codes, check your size standard, and draft the capability statement.
3. Week two: register with your state portal, apply for the certifications you qualify for, and set up saved searches.
4. Ongoing: thirty minutes weekly on your saved searches and award records. Consistency beats intensity in this market.
