The DoD procurement process is the statute-driven system the Department of Defense uses to buy everything from fighter jets to consulting hours, running through federal law (Title 10 and Title 41), the Federal Acquisition Regulation and its defense supplement, a set of tailored acquisition pathways, and a chain of contracting officers and oversight agencies that decide who gets paid and on what terms. For a company that wants to sell to the Department, the process starts long before any solicitation appears: you register, you get cleared where the work requires it, you meet cybersecurity requirements, and you learn the deadlines that govern awards and protests. What follows walks through each of those pieces in the order a contractor actually encounters them.
The Legal Rules That Govern Every Purchase
Federal law sets the frame. Title 10 of the U.S. Code dedicates an entire part to acquisition. Section 3001 defines the defense acquisition system as the workforce, management structure, and regulatory framework that together guide how the Department buys goods and services.1Office of the Law Revision Counsel. 10 USC 3001 – Definitions A 2022 reorganization of Title 10 moved key procurement definitions out of the old 10 U.S.C. § 2302 and into new sections 3002–3015, which now carry terms like “competitive procedures,” “major system,” and “nontraditional defense contractor.”2Office of the Under Secretary of Defense for Acquisition and Sustainment. Title 10 Reorganization Title 41 covers public contracts more broadly, applying transparency and competition requirements across all federal agencies.3Legal Information Institute. US Code Title 41 – Public Contracts
Those statutes get translated into day-to-day rules by the Federal Acquisition Regulation, or FAR, which sets uniform policies for contracts across every executive agency.4Acquisition.GOV. Federal Acquisition Regulation On top of the FAR sits the Defense Federal Acquisition Regulation Supplement (DFARS), which adds military-specific requirements like domestic sourcing rules and cybersecurity standards for contractors handling sensitive data.5Defense Acquisition Regulations System. Defense Federal Acquisition Regulation Supplement and Procedures, Guidance, and Information Every contracting officer follows both. Violations can result in contract termination or debarment from future government work.
Getting Registered to Sell
Before a company can compete for any defense contract, it needs an active registration in the System for Award Management at SAM.gov. Registration is free. You provide your legal business name, physical address, banking information for electronic funds transfer, and the North American Industry Classification System (NAICS) codes that describe your products or services.6General Services Administration. Register Your Business SAM.gov assigns you a Unique Entity Identifier (UEI), which replaced the old DUNS number. You can get a UEI on its own for subaward purposes, but prime contractors need a full registration. Registrations must be renewed every 365 days, and a new registration can take up to 10 business days to process.7SAM.gov. Entity Registration
The government also assigns a five-character Commercial and Government Entity (CAGE) code, which tracks your business across administrative systems. If you plan to pursue classified work, having a CAGE code in place before you start the facility clearance process matters; without one, the clearance process can be delayed or discontinued.8Defense Counterintelligence and Security Agency. Facility Clearances
Companies that need access to unclassified but export-controlled military technical data must be certified through the Joint Certification Program (JCP). Certification requires DD Form 2345, which functions as both application and legal agreement once approved by the JCP Office.9Defense Logistics Agency. DLA Sponsored DD Forms Certified firms can access technical data supporting defense-related research, manufacturing, and contract performance.10Defense Logistics Agency. Joint Certification Program
Who Runs Acquisition and Who Watches It
The Under Secretary of Defense for Acquisition and Sustainment (USD(A&S)) sits at the top of the system as the Department’s chief acquisition officer, with authority over policies governing system design, development, prototyping, production, logistics, and maintenance.11Office of the Law Revision Counsel. 10 USC 133b – Under Secretary of Defense for Acquisition and Sustainment Each military branch has a Service Acquisition Executive managing branch-specific programs.
Congress controls the money through the National Defense Authorization Act (NDAA), passed annually to authorize funding levels and give legal permission for military programs.12U.S. Government Publishing Office. National Defense Authorization Act for Fiscal Year 2020 The Government Accountability Office (GAO) supplies Congress with independent, fact-based analysis of defense spending.13U.S. Government Accountability Office. What GAO Does The Defense Contract Audit Agency (DCAA) audits contractor financials to determine whether costs are allowable, properly allocated, and reasonable.14Defense Contract Audit Agency. Defense Contract Audit Agency – Home
If you hold a cost-reimbursement contract, you will interact with DCAA regularly. The agency reviews pricing proposals before award and audits incurred costs after performance. Contractors must submit an incurred cost proposal within six months of their fiscal year-end. DCAA also supports fraud investigations, including cases under the False Claims Act. For cost-type work, clean accounting systems are not a nice-to-have; they determine whether you get paid and whether you win again.
The Adaptive Acquisition Framework
The Department does not force every purchase through a single pipeline. It uses the Adaptive Acquisition Framework (AAF), a set of pathways matching the type of buy with an appropriate level of process and oversight.15Defense Acquisition University. Adaptive Acquisition Framework The AAF has six pathways:
- Urgent Capability Acquisition, for rapidly fielding solutions to immediate warfighter needs.
- Middle Tier of Acquisition, for rapid prototyping and rapid fielding within about five years.
- Major Capability Acquisition, the traditional pathway for large, complex programs like new aircraft or ship classes.
- Software Acquisition, for iterative software development using modern agile practices.
- Defense Business Systems, for IT and business systems.
- Acquisition of Services, for professional, technical, and advisory services.
The pathway chosen determines the milestones, reviews, and documentation required. A major weapons system runs on a very different cadence than a software application.16Defense Acquisition University. Adaptive Acquisition Framework Pathways
From Solicitation to Award
A given acquisition typically begins when the government issues a formal solicitation, most often a Request for Proposal (RFP).17Acquisition.GOV. 48 CFR 15.203 – Requests for Proposals Opportunities are posted on SAM.gov, where contractors can search and track them. Proposals themselves are submitted through the method specified in each solicitation, usually a dedicated electronic portal or an email address, not SAM.gov itself. Evaluation teams score submissions on technical merit, past performance, and price reasonableness, and the government awards to the bidder offering the best value.
Contract Types and How Risk Gets Divided
How financial risk is split between the government and the contractor depends on the contract type. Three main structures cover most defense work.
Fixed-Price Contracts
Fixed-price contracts work best when the product or service is well-defined and costs are predictable. The contractor agrees to deliver for a set amount and absorbs any overruns. The incentive to manage expenses is direct: the contractor keeps more profit when costs come in below the agreed price.
Cost-Reimbursement Contracts
When the Department is pursuing cutting-edge technology or research where costs are genuinely uncertain, it often uses cost-reimbursement contracts. The government pays allowable expenses up to a negotiated ceiling, plus a fee. That shields the contractor from financial risk on unpredictable work, but the trade-off is heavier oversight, including DCAA audits, to ensure costs stay reasonable.14Defense Contract Audit Agency. Defense Contract Audit Agency – Home
Time-and-Materials Contracts
Time-and-materials (T&M) contracts pay direct labor at fixed hourly rates and reimburse the actual cost of materials. The FAR permits T&M contracts only when the scope or duration of the work cannot be estimated with reasonable confidence at the time of award. The contracting officer must document in writing that no other type is suitable, and the contract must include a ceiling price the contractor exceeds at its own risk.18Acquisition.GOV. 48 CFR 16.601 – Time-and-Materials Contracts
Other Transaction Authority
For research projects and prototype development, the Department can use Other Transaction Authority (OTA) under 10 U.S.C. §§ 4021 and 4022. OTAs are not traditional procurement contracts, grants, or cooperative agreements. They are legally binding instruments designed to attract non-traditional defense companies that might otherwise avoid the standard procurement process.19Office of the Law Revision Counsel. 10 USC 4021 – Research Projects: Transactions Other Than Contracts and Grants OTAs bypass many conventional FAR requirements, which makes them well-suited to rapid prototyping and to working with startups or commercial technology firms.20Office of the Under Secretary of Defense for Acquisition and Sustainment. Other Transactions Guide
Cybersecurity Requirements Under CMMC
Any contractor handling federal contract information (FCI) or controlled unclassified information (CUI) must meet the Cybersecurity Maturity Model Certification (CMMC) standards codified at 32 CFR Part 170.21Federal Register. Cybersecurity Maturity Model Certification (CMMC) Program Failing to meet CMMC requirements disqualifies a contractor from award. The program has three levels:
- Level 1 requires compliance with 15 basic safeguarding requirements from FAR clause 52.204-21. Contractors perform an annual self-assessment and submit an annual affirmation. This level covers companies that handle only FCI.
- Level 2 requires compliance with 110 security controls from NIST SP 800-171 Revision 2. Depending on the contract, assessment is either a self-assessment or an independent evaluation by an accredited third-party organization (C3PAO) every three years. Most contractors handling CUI fall here.
- Level 3 adds 24 controls drawn from NIST SP 800-172 on top of Level 2. Assessment is conducted by the Defense Industrial Base Cybersecurity Assessment Center (DIBCAC) every three years. This level targets contractors facing advanced persistent threats.
Phase 1 implementation, running from late 2025 through late 2026, focuses primarily on Level 1 and Level 2 self-assessments appearing in solicitations.22Department of Defense Chief Information Officer. About CMMC Building compliance takes months, and the assessment infrastructure is already in motion, so waiting for a contract requirement to force the issue is a losing approach.
Small Business Set-Asides and the 8(a) Program
The Department maintains specific contracting goals for small businesses. For fiscal year 2025, DoD targeted 23.17% of prime contract dollars for small businesses overall, with additional goals of 5% each for HUBZone firms, service-disabled veteran-owned small businesses, small disadvantaged businesses, and women-owned small businesses.23Department of Defense Office of Small Business Programs. Goals and Performance Set-aside contracts are reserved for qualifying small businesses, which reduces the competitive field considerably.
The SBA’s 8(a) Business Development Program is among the most valuable tools available. To qualify, a firm must be at least 51% owned and controlled by U.S. citizens who are socially and economically disadvantaged, with individual net worth of $850,000 or less, adjusted gross income of $400,000 or less, and total assets of $6.5 million or less. The business must have been operating for at least two years.24U.S. Small Business Administration. 8(a) Business Development Program Certification lasts up to nine years, made up of a four-year development stage followed by a five-year transitional stage, and individuals can participate only once in a lifetime. Eligible firms gain access to sole-source contracts and mentor-protégé arrangements.
Clearances and Export Controls
Classified contracts require both a company Facility Clearance (FCL) and cleared individuals. Contractors cannot sponsor themselves; either a government contracting activity or another cleared defense company must sponsor the FCL request. Key management personnel are then processed for individual background investigations, and the Defense Counterintelligence and Security Agency (DCSA) makes the final determination on who must be cleared.8Defense Counterintelligence and Security Agency. Facility Clearances The timeline is not fast: governance documents are due within 20 days of process initiation, investigation requests and fingerprints within 45 days, and the full clearance often runs well beyond those interim milestones.
Contractors also face export control obligations under the International Traffic in Arms Regulations (ITAR). Any company that manufactures or exports defense articles or provides defense services must register with the State Department’s Directorate of Defense Trade Controls. Violations carry severe civil and criminal penalties. DFARS clause 252.225-7048 flows the requirement down, and contracting officers will direct companies to the State Department for compliance questions rather than answering them.25Office of the Under Secretary of Defense for Acquisition and Sustainment. PGI 225.79 – Export Control
Who Owns the Intellectual Property
How development was funded determines who controls the technical data and software after the contract ends. The DFARS establishes categories of data rights based on funding source.26Office of the Under Secretary of Defense for Acquisition and Sustainment. DFARS 252.227 – Intellectual Property Provisions If the government fully funded development, it generally receives unlimited rights to use, reproduce, and distribute the technical data or software. If the contractor funded development entirely with private money, the contractor retains restricted rights (for software) or limited rights (for technical data), and the government’s use is significantly constrained. Mixed funding produces “government purpose rights,” which allow the government to use the data for any government purpose for five years, after which the rights typically become unlimited.
Contractors participating in the Small Business Innovation Research (SBIR) or Small Business Technology Transfer (STTR) programs get an extended protection period of 20 years for data developed under those awards. Document your development funding carefully. Failing to assert IP restrictions in writing before contract award can let the government claim broader rights than you intended to give.
Fraud, Kickbacks, and Procurement Integrity
Three federal statutes shape the enforcement side of defense contracting.
The False Claims Act
The False Claims Act (31 U.S.C. § 3729) targets anyone who knowingly submits a false claim for payment to the government. The statutory penalty is treble the government’s damages, plus a per-claim civil penalty adjusted annually for inflation. The base statutory range is $5,000 to $10,000 per false claim before adjustment; as of 2025, inflation adjustments push those figures above $14,000 and $28,000 respectively.27Office of the Law Revision Counsel. 31 USC 3729 – False Claims Overbilling the government by $1 million can produce a $3 million damages judgment plus stacked per-claim penalties. The Act also allows private citizens to file suit on the government’s behalf and collect a share of any recovery.
The Anti-Kickback Act
The Anti-Kickback Act (41 U.S.C. § 8701) prohibits providing or accepting anything of value to improperly influence the award or performance of a government contract or subcontract.28Office of the Law Revision Counsel. 41 USC Ch. 87 – Kickbacks It reaches payments between prime contractors and subcontractors, not just bribes to government officials. Money, gifts, credits, and “compensation of any kind” all qualify.
The Procurement Integrity Act
The Procurement Integrity Act (41 U.S.C. §§ 2101–2107) prohibits obtaining or disclosing non-public procurement information, such as a competitor’s bid pricing or the government’s internal cost estimates. Criminal penalties include up to five years in prison. Civil penalties reach $50,000 per violation for individuals and $500,000 per violation for organizations, plus twice the compensation received or offered for the prohibited conduct.29Office of the Law Revision Counsel. 41 USC 2105 – Penalties and Administrative Actions Violations can also lead to debarment, which effectively ends a company’s ability to compete for any government contract.
Bid Protests and the Deadlines That Matter
If a contractor believes the government erred in the award process, whether by evaluating proposals inconsistently, failing to follow the solicitation’s stated criteria, or applying unstated evaluation factors, the primary remedy is a bid protest filed with the GAO. The deadlines are strict.
Protests challenging problems visible on the face of the solicitation must be filed before the deadline for submitting proposals. All other protests must be filed within 10 calendar days of when the protester knew or should have known the basis for the protest.30eCFR. 4 CFR 21.2 – Time for Filing If the procurement requires a debriefing, common in negotiated procurements under FAR Part 15, a protest based on information learned during the debriefing must be filed within 10 days after the debriefing. If a company first protests to the contracting agency and receives an unfavorable response, the subsequent GAO protest must be filed within 10 days of that adverse action.
Missing these windows by a day results in dismissal. The GAO filing cutoff is 5:30 p.m. Eastern. If you think you may want to protest, start the clock in your head the moment the ground for protest becomes known, not the moment you decide to act.
