Prime Contractor vs Subcontractor
Compare being a prime contractor vs subcontractor in government contracting. Understand the responsibilities, risks, and rewards of each role to build your federal business.
A prime contractor holds the direct contract with the government and is fully responsible for contract performance. Primes control the work, manage subcontractors, and bear all contractual obligations to the government. They receive payment directly from the government and are accountable for schedule, cost, and technical performance. Being a prime offers higher rewards but comes with greater responsibility and risk.
A subcontractor works under a prime contractor to perform a portion of a government contract. Subs do not have a direct contractual relationship with the government but with the prime. Subcontracting is often the entry point for new government contractors, allowing them to build past performance and learn the market while a more experienced prime handles government interface and contract administration.

Most successful government contractors do both - subcontracting to build experience and relationships while developing prime capabilities. Subcontracting is often the right starting point for new entrants, allowing you to learn the market and build past performance with lower risk. Transitioning to prime contractor roles offers higher rewards but requires investment in capabilities, bonding, and business development. The optimal path depends on your current experience level and growth ambitions.
Choose Prime Contractor if you:
- Have relevant past performance already
- Want higher margins and revenue
- Can handle bonding and insurance requirements
- Want direct customer relationships
- Ready for full contract responsibility
Choose Subcontractor if you:
- New to government contracting
- Building initial past performance
- Learning government processes and culture
- Limited bonding or insurance capacity
- Want lower risk while growing capabilities
Should I start as a subcontractor or prime?
Most new contractors should start with subcontracting. It allows you to learn government processes, understand agency requirements, and build past performance with lower risk. Once you have 2-3 years of relevant subcontracting experience, you are better positioned to compete for prime contracts with credible past performance.
Can subcontracting experience count as past performance?
Yes, but with limitations. When proposing as a prime, you can cite your subcontracting experience. Evaluators typically value prime experience more highly, but subcontracting shows relevant capability. Be sure your subcontract agreements allow you to use the experience for proposal purposes and get strong references from your primes.
What is a teaming agreement vs. subcontract?
A teaming agreement is formed before contract award, committing companies to work together if they win. After award, this becomes a subcontract with specific terms. Teaming agreements outline general roles and commitment; subcontracts define specific scope, pricing, and legal obligations. The teaming agreement is the dating phase; the subcontract is the marriage.
How do I find prime contractors to subcontract with?
Research primes winning contracts in your area at FPDS.gov, USASpending.gov, or GovWin. Check the SBA's SubNet for subcontracting opportunities primes have posted. Attend industry days where primes recruit teammates. Network at government contracting events. Many primes have small business liaisons specifically to find qualified subcontractors.
What percentage do prime contractors typically take?
Prime markups vary widely based on the work, risk, and value they add. For labor-based work, primes might add 8-15% overhead on subcontractor costs. Some primes take more on higher-risk work. Negotiate based on what services the prime provides (BD, contract management, facilities) versus pure pass-through. Markups should reflect real value.
Can I be both a prime and subcontractor?
Yes, most mid-size contractors operate as both. You might be a prime on contracts matching your core capabilities while subcontracting to larger primes on bigger programs or in adjacent markets. This diversification reduces risk and builds relationships. Just ensure no conflicts of interest on specific opportunities where you might compete with your teaming partners.
