How to Bid on Government Contracts: Step-by-Step Guide for Beginners

Bidding on government contracts follows a structured process that's different from commercial sales. The government publishes opportunities publicly, evaluates proposals against stated criteria, and awards contracts to vendors who meet requirements at the best value.

Here's what you need to know before you start:

• It's free to bid — Registration on SAM.gov and submitting proposals costs nothing. Be wary of companies charging for "registration services."
• Small businesses have advantages — The government sets aside ~23% of contracts specifically for small businesses. Certifications like 8(a), HUBZone, and SDVOSB unlock even more set-aside opportunities.
• Everything is documented — Unlike commercial deals where relationships drive decisions, government awards are based on written proposals evaluated against published criteria.
• Deadlines are absolute — Late proposals are rejected, no exceptions. Plan your timeline carefully.

The full process from registration to winning your first contract typically takes 6-12 months for new contractors. Let's break it down step by step.

Before you can bid on any federal contract, you must register in the System for Award Management (SAM.gov). This is mandatory — without an active registration, you cannot receive a contract award or payment.

During registration, you'll receive:

• UEI (Unique Entity Identifier) — Your 12-character business identifier that replaced the DUNS number
• CAGE Code — Your 5-character Commercial and Government Entity code

What you'll need to register:

• EIN (Employer Identification Number) from the IRS
• Bank account information for electronic payments
• Business address and contact information
• NAICS codes that describe your business activities

Registration takes 7-10 business days for approval. Start this process first — you can research opportunities while waiting for approval.

NAICS codes (North American Industry Classification System) are 6-digit numbers that classify your business by industry. Every government contract is assigned a NAICS code, and you can only bid on contracts that match codes you've registered for.

Choosing the right NAICS codes matters because:

• They determine your size standard — The SBA sets different revenue/employee thresholds for each NAICS code. You might be "small" under one code but not another.
• They filter your opportunity searches — When searching SAM.gov, you'll filter by NAICS code to find relevant contracts.
• They define your competition — Your competitors are companies registered under the same codes.

Most businesses register for 5-10 NAICS codes that cover their core services. Don't register for codes you can't actually perform — misrepresentation can result in debarment.

Government contract opportunities are posted publicly on SAM.gov (formerly FBO.gov). All contracts over $25,000 must be advertised here, making it the primary source for finding opportunities to bid on.

Types of opportunities you'll see:

• Request for Proposal (RFP) — Full competitive solicitation requiring a detailed proposal. Most common for services contracts.
• Request for Quote (RFQ) — Simplified solicitation, typically for products or straightforward services under the simplified acquisition threshold ($250K).
• Sources Sought / RFI — Market research notices. Agencies use these to gauge interest before releasing a solicitation. Always respond to these — they influence whether contracts get set aside for small business.
• Combined Synopsis/Solicitation — Streamlined format that combines the announcement and full solicitation in one document.

How to search effectively:

• Filter by your NAICS codes
• Filter by set-aside type if you're certified (8(a), SDVOSB, etc.)
• Set up saved searches to receive email alerts for new opportunities
• Look at active contracts' response deadlines — aim for 30+ days remaining

Not every opportunity is worth pursuing. Experienced contractors win 20-40% of contracts they bid on — beginners often win less than 10%. The key is being selective about which opportunities to pursue.

Bid if:

• You can clearly meet all mandatory requirements
• You have relevant past performance (even commercial experience counts)
• The contract size matches your capabilities
• You have enough time to write a quality proposal
• You understand the agency and their needs

Don't bid if:

• You can't meet mandatory requirements (certifications, clearances, etc.)
• The incumbent is likely to win and you have no competitive advantage
• You're just "throwing something against the wall"
• The proposal deadline is too tight for quality work

A focused bid on one well-matched opportunity beats scattered bids on ten poor-fit contracts.

Your proposal is your entire sales pitch in written form. Government evaluators score what you write, not what you know — so everything must be explicit, compliant, and compelling.

Key proposal components:

• Technical Approach — How you'll perform the work. Be specific about methodology, tools, and processes. Show you understand the requirement.
• Management Approach — Your team structure, key personnel, quality control, and how you'll manage the contract.
• Past Performance — Similar contracts you've completed. Include contract numbers, client contacts, scope, and outcomes. If you lack federal past performance, use commercial experience.
• Price/Cost — Your pricing, formatted exactly as requested. Must be realistic — abnormally low prices raise red flags.

Critical success factors:

• Follow instructions exactly — Page limits, fonts, margins, and section organization from Section L are mandatory.
• Address evaluation criteria — Section M tells you how you'll be scored. Address every criterion explicitly.
• Use a compliance matrix — Track every requirement and where your proposal addresses it.
• Leave time for reviews — Never submit a first draft. Red team reviews catch fatal flaws.

Submission requirements vary by solicitation, but most federal proposals are now submitted electronically. Here's how to avoid disqualification:

Before submission:

• Verify your SAM.gov registration is active (not expired)
• Confirm you've included all required documents and representations
• Check file formats match requirements (usually PDF)
• Verify page counts are within limits
• Have someone else review the submission checklist

Submission methods:

• Email — Some solicitations accept email submissions. Watch file size limits.
• SAM.gov — Proposals can be submitted directly through the contract opportunity listing.
• Agency portals — Some agencies (DoD, NASA) have their own submission systems.
• Physical delivery — Rare now, but some solicitations still require hard copies.

Timing:

• Submit at least 24 hours early — system issues happen
• Keep your submission confirmation/receipt
• Late submissions are rejected with almost no exceptions

After you submit, the government evaluation process begins. Here's what to expect:

Evaluation timeline:

• Simple acquisitions: 2-4 weeks
• Complex RFPs: 2-6 months
• Large IDIQ/GWAC awards: 6-12+ months

Possible outcomes:

• Award — Congratulations! You'll receive a contract award notice and begin the kick-off process.
• Competitive range — For negotiated procurements, you may be asked to revise your proposal or participate in discussions.
• Unsuccessful — You weren't selected. Request a debriefing to learn why.

Always request a debriefing if you don't win. The government is required to explain their evaluation. This feedback is invaluable for improving future proposals. You'll learn:

• How your proposal scored vs. the winner
• Specific weaknesses in your approach
• What the winning proposal did better

Breaking in without federal past performance is the biggest challenge for new contractors. Here's how to overcome it:

Start small:

• Micro-purchases — Contracts under $10,000 require minimal competition. Agencies can buy directly from you.
• Simplified acquisitions — Contracts under $250,000 have streamlined processes and are often set aside for small business.
• GSA Advantage — Get on a GSA Schedule to access simplified ordering.

Leverage what you have:

• Commercial past performance — Similar private-sector work counts. Frame it in government terms.
• Subcontracting — Partner with established primes to build federal experience.
• Certifications — 8(a), SDVOSB, and HUBZone certifications give you access to less competitive set-asides and sole-source opportunities.

Build relationships:

• Attend industry days and pre-solicitation conferences
• Meet with agency Small Business Offices
• Network with prime contractors who need small business subcontractors
• Use the capability statement you create to introduce your company
