Why Subcontracting Matters in Recruitment

A staffing agency that wins a large enterprise contract without the depth to fulfill it has two choices: turn down work or subcontract to a network of specialist suppliers. Subcontracting allows agencies to accept orders beyond their own capacity or specialist reach, delivering a broader service without building the infrastructure to support it. For clients running MSP programs that prefer a single primary supplier, subcontracting is often the mechanism that makes that single-supplier model viable.

The risk profile is significant. When an agency subcontracts, it remains contractually and legally responsible to the end client for the worker's performance, compliance, and conduct. If a subcontracted worker fails a drug test, commits a workplace safety violation, or turns out to be fraudulently credentialed, the prime contractor answers for it. The convenience of subcontracting does not transfer liability; in most contract structures, it concentrates it.

For agencies building out a supply chain, understanding subcontracting mechanics, both as prime and as sub, determines how relationships are structured, what margins are viable, and what risk controls are non-negotiable.

How Subcontracting Works

In a standard subcontracting arrangement, the prime contractor holds the client-facing agreement and is responsible for all deliverables under that agreement. The prime then engages one or more subcontractors to fulfill specific portions of the scope, typically passing a subset of the client's billing rate to the sub. The spread between what the prime bills the client and what it pays the sub is the prime's margin on that subcontracted work, which must be sufficient to cover the administrative overhead, markup compression, and risk absorption of managing the supply chain.

For staffing specifically, the subcontractor is typically a smaller, specialist agency with deep candidate pools in a particular geography, skill area, or demographic segment. The prime agencies in MSP programs often manage panels of 30-100 subcontractors through a VMS, routing orders to subs based on fill rate history, compliance scores, and specialty match.

Contract structure between prime and sub should address several things: who employs the worker (almost always the sub, not the prime), who carries workers' compensation and liability insurance, the pass-through rate and payment timing, compliance requirements the sub must meet and certify, background check and drug screening standards, audit rights, and the consequences of a compliance failure.

Margin compression is the central commercial tension. If the client pays the prime at a 15% markup and the prime needs to make 4-5% to cover its overhead and risk, the sub receives a rate with a 10-11% markup. For commodity temporary roles, that margin can work. For specialist or high-demand placements, it often does not, which is why experienced subcontractors negotiate rate cards carefully and avoid prime arrangements that make their own margins unsustainable.

Subcontracting vs Staffing Partnership

A staffing partnership typically refers to a formal referral or co-delivery arrangement between agencies at similar levels, often without a subordinate supplier relationship. Subcontracting implies a clear hierarchical structure: prime contractor accountable to the client, subcontractor accountable to the prime. Partnerships tend to involve split fees or referral arrangements; subcontracting involves a supply chain with its own commercial terms, compliance obligations, and risk allocation.

Subcontracting in Practice

Michael, director of enterprise accounts at a national industrial staffing firm, holds a preferred supplier agreement with a Tier 1 automotive manufacturer requiring coverage across eight states. His firm directly fulfills five states where it has strong regional offices. For the remaining three, he subcontracts to two regional agencies with established local candidate pools. The subs receive a pass-through rate that yields them a 9% markup; Michael's firm earns 4.5% on subcontracted placements versus 14% on direct placements. He manages subcontractor compliance quarterly and has terminated one sub after two consecutive failed audit cycles. The arrangement generates $2.1M in annual revenue that the firm could not fulfill without the subcontractor network.
