Before You Bid: Essential Prerequisites
Before you can submit a single bid on a government contract, there are several administrative steps you must complete. Skipping any of these will disqualify your proposal regardless of how good it is, so treat this as your pre-flight checklist.
First, you need an active SAM.gov registration. This is non-negotiable. Every business that does work with the federal government must be registered in the System for Award Management. The registration process requires your business's legal name, address, EIN (Employer Identification Number), banking information for electronic funds transfer, and a description of your goods or services. You will receive a Unique Entity Identifier (UEI) and a CAGE (Commercial and Government Entity) code as part of this process. Plan for two to four weeks for initial registration.
Second, select and verify your NAICS codes. These determine which contracts you are eligible to bid on and which size standard applies to your business. You can list multiple NAICS codes in your SAM.gov profile.
Third, determine your small business size status. The SBA sets different size standards for each NAICS code based on either average annual receipts or number of employees. You must be under the size standard for the specific NAICS code assigned to the contract you are bidding on.
Fourth, if you qualify for any set-aside certifications (8(a), SDVOSB, WOSB, HUBZone), get certified before you start bidding. These certifications open up less competitive solicitations that can dramatically improve your win rate.
Finding the Right Opportunity to Bid On
Not every contract opportunity is worth bidding on. The proposal process requires significant time and effort, and experienced contractors are selective about which solicitations they pursue. A good rule of thumb for new contractors is to focus on opportunities where you can check at least four of these five boxes: your NAICS code matches, you meet the size standard, you have relevant past performance or experience, the scope of work aligns closely with your capabilities, and the contract value is appropriate for your business size.
Start by searching SAM.gov or a contract search tool like FedOverwatch for active solicitations (notice types: Solicitation, Combined Synopsis/Solicitation, or Request for Quote). Filter by your NAICS codes and any set-aside certifications you hold. Read the titles and brief descriptions to create a short list of possibilities.
Pay close attention to the response deadline. Government solicitations have firm deadlines that are rarely extended. If a deadline is less than a week away and you are seeing the solicitation for the first time, it is usually too late to put together a competitive response. Experienced contractors typically want at least two to three weeks of preparation time for a full proposal.
Also check the incumbent. For recompetes (contracts being awarded again after the current period ends), the existing contractor has a significant advantage. This does not mean you should not bid, but know that you will need to clearly differentiate your approach. Award data for most contracts is publicly available on USAspending.gov.
Reading the Solicitation: What to Look For
Once you have identified a promising opportunity, download and carefully read the entire solicitation package. Government solicitations follow a standard structure, and understanding it will save you hours of confusion.
The solicitation will typically include a Statement of Work (SOW) or Performance Work Statement (PWS) that describes exactly what the government wants done. This is the most important section. Read it multiple times and make sure you understand every requirement. If anything is unclear, you can submit questions to the contracting officer during the designated Q&A period.
The evaluation criteria section tells you exactly how the government will score proposals. Common evaluation factors include Technical Approach (how you plan to do the work), Past Performance (evidence that you have done similar work before), Management Approach (your team, project management methodology, and quality control), and Price/Cost (your proposed price). Some solicitations are "lowest price technically acceptable" (LPTA), meaning the cheapest proposal that meets all technical requirements wins. Others are "best value," where the government weighs technical quality against price.
The instructions to offerors section specifies exactly what your proposal must include, page limits, formatting requirements, and how to submit. Follow these instructions to the letter. Proposals that deviate from formatting requirements or exceed page limits can be disqualified without review.
The contract clauses section (usually Section I) contains the Federal Acquisition Regulation (FAR) clauses that apply to the contract. While these can be dense, pay attention to clauses related to payment terms, insurance requirements, security clearances, and small business subcontracting plans.
Writing a Winning Proposal
Your proposal is a sales document that must be organized exactly as the solicitation instructs. Government evaluators score proposals against the stated evaluation criteria, so your proposal structure should mirror those criteria point by point.
For the Technical Volume, start by demonstrating that you understand the problem. Restate the key requirements in your own words to show comprehension, then present your approach to meeting each requirement. Be specific and concrete. Instead of writing "we will provide excellent customer service," write "we will staff a help desk with three certified technicians available Monday through Friday, 7 AM to 7 PM ET, with a 15-minute maximum response time for Priority 1 tickets." Use clear headings, numbered paragraphs, and cross-references to the SOW requirements so evaluators can easily verify compliance.
For Past Performance, identify two to five previous contracts or projects that are similar in scope, size, and complexity to the current opportunity. For each reference, include the client name, contract number (if government), period of performance, dollar value, and a brief description of the work performed and results achieved. Government evaluators will typically contact your references, so make sure they know they may be called.
For the Price Volume, follow the pricing instructions exactly. Government pricing can be complex, involving labor categories with specific hourly rates, materials costs, travel estimates, and fee structures. Your price must be realistic. Unrealistically low prices raise red flags and can lead to your proposal being rejected as technically unacceptable.

Submitting Your Bid: Getting It Right
Submission requirements vary by solicitation, but most federal proposals today are submitted electronically. The solicitation will specify the exact submission method, which may be email to the contracting officer, upload through SAM.gov, or submission through an agency-specific portal such as eBuy (for GSA Schedule orders), DOD eSourcing, or NASA NSSC.
Regardless of the submission method, follow these rules. Submit early. Do not wait until the last hour. Technical glitches, file size limits, and email server delays have caused countless late submissions that were rejected without consideration. Aim to submit at least 24 hours before the deadline.
Double-check all file names and formats. If the solicitation says "submit as a single PDF with the file name [CompanyName]_TechnicalVolume_Sol123456.pdf," do exactly that. Evaluators process dozens of proposals and mislabeled or incorrectly formatted files create a poor first impression.
Keep a submission confirmation. Whether it is an email receipt, a portal confirmation number, or a read receipt, save documentation that proves you submitted on time. If there is ever a dispute about whether your proposal was received, this evidence is critical.
After submission, monitor SAM.gov for any amendments to the solicitation. Sometimes the government will extend the deadline, change requirements, or issue answers to vendor questions. If you have already submitted, you may need to revise and resubmit your proposal to address these changes.
Finally, be patient. The evaluation process can take weeks or even months depending on the complexity of the procurement. You will receive a notification of award or non-selection. If you are not selected, you can request a debriefing from the contracting officer to understand how your proposal was evaluated and how to improve for next time. These debriefings are incredibly valuable for improving your win rate on future bids.
Common Bidding Mistakes to Avoid
After analyzing thousands of government proposals, the same mistakes appear over and over. Avoiding these will immediately put you ahead of many competitors.
Not reading the entire solicitation is the most common and most costly mistake. Contractors often skim the SOW and start writing without reading the evaluation criteria, instructions, or clauses. This leads to proposals that are technically non-compliant or that emphasize the wrong things.
Ignoring page limits and formatting requirements is another frequent disqualifier. If the solicitation says 20 pages with 12-point Times New Roman font and 1-inch margins, exceeding those limits means your extra pages will not be evaluated, or worse, your entire proposal will be rejected.
Failing to directly address each evaluation factor is a critical error. Evaluators use a scorecard based on the stated criteria. If your proposal does not clearly address each factor, you will receive a low score even if your actual capabilities are strong.
Submitting a generic proposal that is not tailored to the specific solicitation is a reliable way to lose. Evaluators can tell immediately when a proposal has been copy-pasted from a previous submission without customization. Reference the specific agency, the specific SOW requirements, and explain why your approach is the right fit for this particular contract.
Underpricing your proposal to win on cost alone is a dangerous strategy. If the government believes your price is too low to successfully perform the work, they can reject your proposal as technically unacceptable. Price realistically and let your technical approach carry the evaluation.
