How To Bid On Government Contracts: A First-Time Bidder Checklist
Short answer: to bid on government contracts, you get your codes and registrations in order (NAICS codes and a free SAM.gov registration for federal work, or the state or city vendor registration for local work), find solicitations that fit, read the whole package, answer every requirement in the format it asks for, price it carefully, sign the offer form, and submit before the deadline.
That is the whole path. The details are where first-time bidders lose. Here is the checklist we would hand a friend starting today.
Before You Find A Bid
1. Know Your NAICS Codes And Your Size
Every federal solicitation is assigned a North American Industry Classification System (NAICS) code with a size standard. Your business counts as "small" for that bid only if you fall under that size standard, which the SBA sets as either average annual receipts or number of employees, depending on the industry. Look up the codes that match the work you actually do, and check your size against each one with the SBA's size standards tool.
2. Register In SAM.gov (It Is Free)
For federal work, you need an active registration in the System for Award Management at SAM.gov when you submit an offer and at the time of award. SAM.gov says plainly that it is free to use: no charge to get a Unique Entity ID, register, or maintain your registration. Watch out for companies that charge to "register" you. Plan for the registration to take time, start well before you need it, and renew it every 365 days.
3. Register Where Your State And City Buyers Post
State and local governments have their own vendor systems. Texas, for example, posts solicitations on the Electronic State Business Daily, and Georgia buyers advertise on the Georgia Procurement Registry. Register with the states and cities you want to sell to, and choose your commodity codes carefully so the right bid notices reach you.
Finding And Choosing The Right Bid
4. Search For Opportunities
Federal opportunities are posted on SAM.gov under Contract Opportunities. Filter by your NAICS codes, set-aside type, and place of performance, and save the searches so new notices come to you. Do not ignore early notices like Sources Sought and Presolicitation. They tell you what is coming and let you shape it.
5. Decide Bid Or No-Bid
Ask these questions before you spend a week writing:
Question | Why It Matters |
|---|---|
Can we do this exact work, at this size, in this place? | Evaluators rate relevance and capability |
Are we eligible for the set-aside? | Ineligible offers are not considered |
Do we have past performance that is close to this scope? | It is usually a scored factor |
Can we meet every license, certification, and key person requirement? | Missing one can be a deficiency |
Does the Statement of Work name another company as the performer? | You may need authorization or a teaming partner |
Can we price it at a profit, at or above any wage determination? | Underpriced labor is a problem on day one |
Do we have the time to write it well? | A rushed bid is how requirements get missed |
If most answers are yes, bid. If several are no, it is often better to pass and save your energy for a better fit.
Writing The Bid
6. Read The Entire Package
Read the solicitation, every attachment, every amendment, and any posted questions and answers. Find the due date and time, the submission method, the question deadline, and the evaluation method.
7. Build A Compliance Matrix
List every requirement word for word, with its section and page, and where your proposal answers it. Our compliance matrix guide has a ready-made layout.
8. Ask Questions Before The Deadline
If something is unclear, email the contracting officer named in the solicitation before the question deadline. Be short and specific. Answers often come back as an amendment, which you must acknowledge.
9. Write To The Evaluation Factors
Follow the instructions for structure (Section L or the instructions provision) and use the words of the evaluation factors (Section M or the evaluation provision) in your answers. Explain how you will do the work, not just that you will.
10. Price It
Build your price from the real cost: labor (at or above any wage determination in the package), materials, equipment, travel, overhead, and profit. Fill in every line item and option year.
11. Complete The Forms
Fill in and sign the offer form (often the SF 1449, SF 33, or SF 1442), acknowledge every amendment, and complete every representation and certificate the solicitation asks for. These are pass or fail items.
Before And After You Submit
12. Review With Fresh Eyes And Submit Early
Have someone who did not write the proposal check it against the matrix and the evaluation factors. Then submit a day early if you can, using only the method the solicitation allows, and keep proof of receipt. Late offers are generally not considered. Our list of why government proposals get rejected covers the twelve most common last-minute misses.
13. Ask For A Debriefing
Win or lose, ask what the evaluators saw. A debriefing is the cheapest coaching in government contracting.

A note on rule numbers: in 2025 the federal government began rewriting the Federal Acquisition Regulation (the Revolutionary FAR Overhaul). Most agencies now use overhaul deviation text, and the formal rule was still in progress in October 2026, so a section number in your solicitation may differ from the one cited here. When they differ, follow your solicitation. GradeTheBid is not a law firm, and this article is general education, not legal advice.
