The Vendor Journey

LLC, S-Corp, or C-Corp — register with your state, draft operating agreements, set up governance structure. The legal foundation for everything else.

Employer Identification Number — the federal tax ID every business needs. Quick online application, but required before bank accounts or SAM registration.

Government payments require a dedicated business bank account. Needed for ACH direct deposits and to separate personal from business finances.

Choose from 6,000+ North American Industry Classification System codes. These determine which contracts you can bid on, your size standard, and set-aside eligibility.

Unique Entity Identifier — replaced DUNS numbers in 2022. Assigned through SAM.gov, this is your company's universal ID across all federal systems.

System for Award Management — the mandatory gateway for all federal contractors. Initial registration takes hours; must be renewed annually or you lose eligibility mid-contract.

The Small Business Administration sets revenue and employee thresholds for each NAICS code. Your size status controls access to billions in small business set-asides.

Defense Contract Audit Agency requires cost-accounting systems that track direct/indirect costs, labor rates, and overhead pools. Most commercial accounting software doesn't qualify — specialized systems or consultants are required.

8(a) Business Development, HUBZone, Women-Owned Small Business (WOSB), Service-Disabled Veteran-Owned (SDVOSB). Each certification opens set-aside opportunities but requires months of documentation and ongoing compliance.

Cybersecurity Maturity Model Certification — required for Department of Defense contracts. Level 2+ demands third-party assessment. The cost of IT infrastructure upgrades alone can exceed $100K for small firms.

Bid bonds, performance bonds, and payment bonds — required for construction contracts over $150K. Bond capacity depends on your financial history, locking out younger firms.

General liability, professional liability (E&O), workers' comp, cyber liability. Specific coverage requirements vary by contract type and agency.

A 1–2 page marketing document — essentially your resume for government buyers. Core competencies, past performance, differentiators, NAICS codes, and socioeconomic status. Professional design matters.

The ultimate Catch-22 of federal contracting: you need past performance to win contracts, but you need contracts to build past performance. Most new entrants start as subcontractors, accepting low margins for years to build a record.

Small Business Search profile on SAM.gov — where contracting officers and prime contractors find small businesses. An incomplete profile means missed teaming and subcontracting opportunities.

Thousands of opportunities posted weekly. Finding the right ones requires daily monitoring, complex keyword searches, and understanding agency-specific posting patterns.

A typical solicitation runs 50–200+ pages of requirements, evaluation criteria, special clauses, and compliance mandates. Reading it carefully is a multi-day effort — and most won't be worth pursuing.

Pre-solicitation conferences where agencies brief potential bidders. Often in-person (travel costs), and sometimes the only way to get real insight into what the agency actually wants.

Formal question-and-answer period where vendors seek clarification. Answers are typically published to all bidders. Strategic questioning is an art — revealing too much tips off competitors.

The core of your bid: technical approach, management plan, staffing, quality assurance, transition plan. Large proposals require dedicated teams of writers, SMEs, and reviewers working for weeks.

Detailed cost volumes with labor categories, rates, indirect rates, fee structures, and basis-of-estimate. Must be consistent with the technical approach and defensible under audit.

Documented evidence of relevant contract performance — project descriptions, client references, CPARS ratings. References must be contactable and willing to vouch for you on this specific type of work.

Late = disqualified. No exceptions. Even a 1-minute delay after the deadline means your entire investment is wasted. Electronic submission systems sometimes crash on deadline day.

Evaluation boards score proposals against stated criteria. For best-value procurements, technical merit may outweigh price. For LPTA, only the cheapest technically acceptable proposal wins.

In best-value procurements, the government may open discussions with firms in the competitive range. LPTA procurements typically skip this — another reason best-value is more nuanced but also more equitable.

The contracting officer selects a winner. Losers receive a brief debriefing explaining the rationale — often vague enough to be unhelpful for improving future bids.

If you believe the evaluation was unfair, you can protest to GAO or the Court of Federal Claims. Legal fees are enormous, outcomes uncertain, and the process can delay the entire program by 100+ days.

Transition planning, security clearance processing, badging, IT access. Even after winning, it can take weeks before you start earning revenue on the contract.
