5 Mistakes First-Time GovCon Bidders Make

Mistake 1: Not Registering in SAM.gov Early Enough

The most common mistake new contractors make is underestimating how long SAM.gov registration takes. The process requires a DUNS number (now UEI), banking information, NAICS code selection, and sometimes entity validation that can take 2-4 weeks. Many first-time bidders discover an opportunity with a 30-day response window, only to realize they cannot submit a proposal because their SAM registration is still pending.

Start your SAM.gov registration before you even identify your first opportunity. The registration is free, and maintaining an active profile costs nothing. Make sure your entity information, NAICS codes, and socioeconomic certifications are all current.

Mistake 2: Bidding on Everything Instead of Targeting

New contractors often cast a wide net, responding to every opportunity that mentions their industry. This scatter-shot approach wastes time and resources. Experienced contractors know that a well-targeted bid — where you have relevant past performance, the right NAICS code, appropriate size standard, and a relationship with the buying agency — is worth ten generic submissions.

Focus on opportunities where you have at least three of these five factors: relevant past performance, correct NAICS code, appropriate clearance level, geographic proximity to the place of performance, and an existing relationship with the contracting office. Quality over quantity wins in government contracting.

Mistake 3: Ignoring the Evaluation Criteria

The solicitation document tells you exactly how your proposal will be scored. Many first-time bidders skim past the evaluation factors section (usually Section M in an RFP) and write proposals that emphasize their company strengths rather than addressing what the government actually asked for. If technical approach is weighted at 40%, past performance at 30%, and price at 30%, your proposal should allocate its effort accordingly.

Mistake 4: Underpricing to Win

Racing to the bottom on price is a classic first-timer mistake. Government evaluators use price realism analysis — if your price is significantly below the Independent Government Cost Estimate (IGCE), they may conclude that you do not understand the requirements or cannot perform the work. Price your proposals to be competitive but realistic. Include your full indirect rate structure, fringe benefits, and a reasonable profit margin.

Mistake 5: Not Building a Team Before Bidding

Large federal contracts often require capabilities that no single small business possesses. First-time bidders who try to go it alone on a contract requiring multiple labor categories, security clearances, or specialized equipment frequently lose to teams that have pre-arranged teaming agreements or mentor-protege relationships. Start building your teaming network early — attend industry days, join PTAC workshops, and reach out to primes who need small business subcontracting partners.
