Prime Contractor vs Subcontractor: Pros and Cons

When to Prime vs When to Sub

Prime When:

• You have the relevant past performance and technical capability to lead the effort
• The contract is set aside for your socioeconomic category (8(a), SDVOSB, HUBZone, WOSB)
• You want to build your prime contract resume for future larger opportunities
• You have the infrastructure: accounting system, insurance, clearances, project management
• Your capture intelligence indicates a strong competitive position

Sub When:

• You lack the past performance to compete credibly as a prime
• The contract requires capabilities beyond your current scope
• You want to learn the customer and domain before priming a follow-on
• The compliance burden of priming exceeds your current capacity
• You provide a niche specialty that complements a larger team
• The relationship with the prime provides strategic value beyond the contract itself

Building from Sub to Prime

Many of today's most successful government contractors started as subcontractors and strategically transitioned to priming. This "sub-to-prime" pathway is a proven growth strategy, especially for small businesses entering the federal market.

Use subcontracting engagements to build three critical assets: domain expertise (understanding the customer's mission and processes), past performance (demonstrating your ability to deliver), and relationships (building trust with the end customer and contracting office). Each subcontract should be chosen strategically to fill gaps in your prime readiness.

When you are ready to prime, target contracts that are smaller than or equal to the largest subcontract you have performed. If your largest subcontract was $5M in annual revenue, pursue prime contracts in the $3-8M range. Evaluators will question a leap from $2M sub to $50M prime. Grow incrementally.

Consider the SBA Mentor-Protege program as an accelerator. A mentor-protege relationship with a large prime gives you access to their past performance, systems, and customer relationships while building your independent capabilities. The mentor benefits from small business subcontracting credit and access to set-aside contracts through joint ventures.

Subcontractor Rights and CDA Flow-Down

Subcontractors have limited direct rights under federal procurement law. Your contractual relationship is with the prime contractor, not with the government. You cannot file a claim directly with the Contracting Officer under the Contract Disputes Act (CDA) — only the prime can assert CDA claims. However, you can require the prime to "sponsor" your claim by passing it through to the government.

The prime contractor is required to flow down certain FAR and DFARS clauses to subcontractors, including equal opportunity, anti-kickback, and various compliance requirements. However, the specific flow-down requirements depend on the subcontract value, type of work, and the clauses in the prime contract. Review your subcontract agreement carefully to understand which obligations apply to you.

Payment protection is a critical concern for subcontractors. FAR 52.232-27 requires prime contractors to pay subcontractors within a specified timeframe (typically within 7-10 days of receiving payment from the government). If a prime is consistently late paying, you may have recourse through the contracting officer, who can withhold payments from the prime until subcontractors are paid.

Negotiate your subcontract terms carefully. Ensure the subcontract includes clear scope of work, payment terms, termination provisions, intellectual property rights, and dispute resolution mechanisms. Do not assume the prime's standard subcontract template protects your interests — have it reviewed by counsel familiar with government subcontracting.
