Never sold to the government? Start here.

Five short lessons, free to read, about four minutes each. Each one ends with one thing to do in WARNO.

1. How federal contracting works

About 4 minutes

How a federal contract works: notice, offer, award, delivery, payment Five steps in a row joined by arrows. An agency posts a notice on SAM.gov; you send an offer by the due date; the agency awards a contract; you deliver the work; the agency pays, about 30 days after a correct invoice. The third step, award, is highlighted in gold because it is the moment the government decides. 1Noticeposted on SAM.gov 2Your offerby the due date 3Awardthe agency decides 4Deliveryyou do the work 5Paymentmost contracts: 30 daysafter a proper invoice,or acceptance if later Everything else in these lessons is detail on one of these five steps. Payment: due on the later of the 30th day after a proper invoice is received or the 30th day after acceptance; interest is paid if late.FAR 52.232-25 (JAN 2017), eCFR read Oct 13, 2026; some foods have shorter periods.

The government is a customer like any other. It needs things done and things delivered, and it buys them from private companies through contracts. A contract says what you will deliver, by when, and what you will be paid.

Three questions explain most of it.

  • Who buys? Agencies, and inside each agency, small contracting offices. A contracting officer is the person who is allowed to sign a contract for the government. Offices buy the same kinds of things again and again, so a buyer who bought what you sell last year is the best lead you can have.
  • Where do you find the work? Most larger purchases are announced in public. The official place is SAM.gov, in its Contract Opportunities section. WARNO reads those notices and the ones from other countries, and scores each one against the codes and words in your profile.
  • How do you get paid? You deliver, the buyer accepts the work, and you send an invoice. The contract says how and where to invoice. Nothing is paid for work the contract does not cover, so read it before you start.

Not every purchase is a big proposal. Small purchases are often quick: a quote, a government card, a short form. Bigger ones ask for a written proposal that the buyer scores against published rules. The notice tells you which kind you are looking at, and lesson 3 shows how to read it.

Some work is set aside: only small businesses, or only businesses with a certain status, may bid. A set-aside can help a new company because only eligible firms compete, but you must qualify.

You do not need past government contracts to start. You do need to be registered (lesson 2), to look at the right notices (lesson 3), and to choose your opportunities with care (lesson 4).

Find notices that fit you

2. Get registered

About 5 minutes. Start the registration today: it takes the longest.

Get registered: entity, EIN, SAM.gov registration, UEI and CAGE, SBA profile Five steps joined by arrows: form your legal entity with one name and one street address; get an EIN from the IRS; register in SAM.gov, which creates your UEI and assigns a CAGE code; wait while the government validates, on average 10 to 15 business days; complete the SBA profile if you chose small-business codes. The SAM.gov step is highlighted in gold because it is the one every bid depends on. A footer says the registration is free and must be renewed every 365 days. 1Your companyone legal name,one street address 2EIN from the IRSfree, online 3Register in SAM.govcreates your UEI;CAGE code assigned afteryou submit 4ValidationIRS and CAGE checks;10 to 15 business days 5SBA profileif you chose small-business codes Free.

To bid as a prime, your company must be registered in SAM.gov. Registration is free. There is no charge to get a Unique Entity ID, register, or renew. Anyone who asks for money is filling in the same forms for you.

When you finish you get a UEI, the Unique Entity ID: a 12-character number that names your company in every federal system. A UEI on its own lets you appear as a subcontractor, but you cannot bid as a prime without the full registration. Choose the type that covers "all awards" so you can bid on contracts and apply for grants.

Have these ready before you start:

  • Your legal business name and physical address, as the IRS has them. A P.O. box is not accepted.
  • The date and state of incorporation, and your tax ID.
  • Your bank's routing and account number, for payments.
  • Your NAICS codes: the industry labels that say what you sell. Choose a few you really sell, with your main one first. WARNO can find them from a sentence about your work.
  • Points of contact, and answers to the representations and certifications questions.

Official sources: start the registration and the official registration checklist (PDF).

Plan for time. The official guidance is to allow at least 10 business days (10-15 on average) after you submit before the registration becomes active, and longer if validation needs documents. A wrong name or address is a common cause of delay. The registration must be renewed every year, so put the date in your calendar.

If your company has a small-business status, the Small Business Administration lists the contracting assistance programs (8(a), HUBZone, women-owned, service-disabled veteran-owned) and you apply at certifications.sba.gov. Not having one is fine: in your WARNO profile, "none" is a valid answer, and it is better to say so than to leave it blank.

3. Read a notice

About 4 minutes

The parts of a notice, and what each one tells you A notice drawn as a page with six labelled parts: the type (sources sought, presolicitation, solicitation, combined synopsis, award), the set-aside (who may bid), the NAICS and PSC codes (what is bought), the due date and time with its time zone, the attachments (where the real requirements are), and the contracting officer's contact for questions. Callout lines point from each label to its place on the page. The due date is marked in gold because it is the one part that decides whether you can act at all.

Every opportunity starts as a notice. You can read one in a minute if you know where to look. Start with the type, because it tells you what to do.

  • Sources sought (also called a request for information). The buyer is asking who could do the work. You are not bidding yet. Answering tells the buyer you exist and can help shape the requirement; it does not guarantee an invitation.
  • Presolicitation. Advance notice that a solicitation is coming.
  • Combined synopsis/solicitation. The notice and the request for quotes in one. Treat it as a solicitation.
  • Special notice. Other information from the buyer, such as an industry day.
  • Solicitation. The real request. It has the instructions, the due date, and how offers will be scored.
  • Award notice. Who won. Useful later: it shows who your competitors are and what the buyer pays.

Then check five things, in this order:

  1. The response date. A late offer is usually not looked at. If you cannot finish in time, skip it.
  2. The set-aside. If it is reserved for a status you do not have, you cannot win it. WARNO marks these.
  3. The NAICS code and what is being bought. Does it match what you sell? Read the description, not only the title.
  4. The place of work. Some jobs must be done on site. Others are remote.
  5. The attachments. The real requirements are usually in the attached documents, not in the notice text.

Last, look at how the buyer will choose. Some buy on lowest price among offers that meet the minimum. Others weigh quality and past work against price. Also check whether past performance is required. If it is and you have none, a team with a company that does is a normal answer.

You will not win every notice. Reading many, quickly, is how you learn which ones suit you. A saved search with an alert does that work for you each day.

4. Decide to bid, and find the right door

About 4 minutes

The eight-line bid or no-bid sheet A score sheet with eight lines, each a question with a yes, no or unknown mark: can we bid (set-aside, size, clearances), can we do every requirement, do we have the past performance they ask for, who won it last time, can we be paid fairly, do we have the hours to write it, what is the fit score, and the decision with reasons. A sample is filled in: six yes, one no, one unknown, decision: bid, with the no (bid bond) listed as the thing to fix. The sheet says one written yes or no with reasons is the output. Bid or no-bid: 140R4026Q0141, Pumping Plant No. 3 roofOne hour per notice. A written yes or no with reasons is the output. 1Can we bid? set-aside, size, clearances, licences 2Can we do every requirement in the statement of work? 3Past performance: do we hold what they ask for? 4Who won it last time, and at what price? (FPDS, USAspending) 5Can we be paid fairly: price floor, bonds, cash flowbid bond not on file 6Do we have the hours to write it before the due date? 7Fit score and the reasons behind it68%, strong fit 8Decision: bidSix yes, one no, one unknown. Fix first: add the bid bond. Recorded Oct 15 on the pipeline card. How to use it A "no" on line 1 ends it: you cannotbid at all. A "no" on lines 2 to 6 is a thing tofix or a reason to skip; write which. "Unknown" means ask in the Q&Aperiod, not guess. The fit score is WARNO's reading oflines 1 to 3 against your profile;it never replaces lines 4 to 6. Keep the sheet: it is your recordwhen the debrief comes. Set-aside eligibility: FAR 19.502-2(eCFR, read Oct 13, 2026 by the Analyst). The eight-line bid or no-bid sheet (phone layout) The same eight-line score sheet as the wide picture, with the how-to-use note below the card instead of beside it: six yes marks, one no (bid bond not on file), one unknown, decision: bid, with the thing to fix first. Bid or no-bid: Pumping Plant No. 3 roofOne hour per notice. A written yes or no with reasons. 1Can we bid? set-aside, size, clearances,licences 2Can we do every requirement in thestatement of work? 3Past performance: do we hold whatthey ask for? 4Who won it last time, at what price?(FPDS, USAspending) 5Can we be paid fairly: price floor,bonds, cash flowbid bond not on file 6Do we have the hours to write itbefore the due date? 7Fit score and the reasons behind it:68%, strong fit 8Decision: bidFix first: add the bid bond. How to use it A "no" on line 1 ends it: you cannot bid at all. A "no" on lines 2 to 6 is a thing to fix or areason to skip; write which. "Unknown" means ask in the Q&A period,not guess. The fit score is WARNO's reading of lines 1 to 3against your profile; it never replaces 4 to 6. Keep the sheet: it is your record when thedebrief comes. Set-aside eligibility: FAR 19.502-2 (eCFR, readOct 13, 2026 by the Analyst).

A proposal takes real time. Bidding on everything is the most common mistake. Before you write anything, answer four questions about a notice.

  1. Can we do it? Do you have the skills, the staff and the places the work needs?
  2. Can we win it? Is it set aside for a group you belong to? Does the buyer ask for experience you can show or borrow?
  3. Do we know the buyer? A buyer who has heard of you before the solicitation comes out has a real advantage. Look up the office in WARNO: what it bought, how much, and who won.
  4. Is the price worth it? Count your hours. A win you lose money on is not a win.

Then choose the door. There are three common ones for a company that is new.

  • Directly, as a prime, on small purchases and on notices set aside for small businesses.
  • Through a contract vehicle. Some buyers only order from a pre-approved list, for example a GSA schedule. Getting on one takes time, and it has its own entry conditions, so treat it as a second step, not a first one.
  • As a subcontractor or teaming partner to a company that already holds the contract or is bidding on it. This is a valid way to get your first past performance. WARNO's People Finder and Company Research show who wins in your field.

Past performance is your record of finished work, for the government or for anyone else. Buyers ask for it because it is the best sign you will deliver. Write down every job you can describe with a result, so you are ready when a notice asks.

Pick one opportunity you can win and follow it.

5. Write the proposal, then deliver

About 5 minutes

Write the proposal, then deliver: from sections L and M to payment A timeline of six points. Read sections L and M; build the compliance matrix; write the volumes (technical, past performance, price); submit early and keep the receipt; award, then kickoff; deliver and invoice. The submit point is highlighted in gold because a late offer is generally not considered. A footer names the clauses.

A good proposal answers what the buyer asked, in the order the buyer asked it, and makes it easy to score. It does not need to be long. It needs to be complete.

  1. Read the instructions twice. They tell you the format, the page limits, what to include and where to send it.
  2. Build a compliance matrix. A simple table: every requirement on the left, the page where you answer it on the right. It stops you missing something and it helps the reader.
  3. Show, do not claim. Say what you will do, who will do it, and one example where you did something similar.
  4. Price clearly. Follow the buyer's price format exactly. Add up your real costs first.
  5. Submit early. Use the method the notice names, and keep the receipt. Do not wait for the last hour.

If you lose, ask for a debrief. On most larger buys you can request one, and the answers make the next offer better.

If you win, the work begins. Deliver what the contract says, when it says it, and invoice the way it says. Keep your records. For larger contracts the buyer's evaluation (CPARS) is added to the government's past-performance record, and the next buyer can read it. A good first job is worth more than the first payment.

You do not have to start from a blank page. WARNO can draft a first version of a proposal from a notice and your profile, and you can add the finished job to your past performance so it scores in future matches.

General guidance, not legal advice. Rules change; confirm numbers and dates on SAM.gov and with the buyer before you rely on them.
