Prime, Sub, Sub-Sub: Where Your Bill Rate Really Goes

You know your bill rate. Or you think you do. Someone mentioned a number in passing during the interview, or you saw it on a job board, and you assumed that's what's flowing to your paycheck minus taxes. It isn't.

Between the client who's actually paying for your work and the check you deposit, there can be one, two, sometimes three companies taking a cut. Each one is legitimate. Each one is invisible unless you ask. And the difference between a good vendor chain and a bad one can be 15-20 points of your rate, gone before you ever see it.

This isn't a conspiracy theory. It's how the industry is built. But you should understand the plumbing before you sign anything.

What a prime-sub-sub chain actually looks like

A large enterprise client rarely staffs contractors directly. They sign a Master Service Agreement with a prime vendor — often a big systems integrator or a preferred staffing partner on their approved vendor list. That prime may not have the specific talent pipeline, so they subcontract to a smaller staffing firm. That firm may itself work through another layer if they don't have the direct relationship or the bench.

So the chain looks like this: Client → Prime → Sub → Sub-Sub → You. Every arrow in that chain is a markup. Every markup is a percentage taken off the number the client is actually paying, before it reaches your rate.

Illustrative math: where the money goes

These numbers are illustrative, not a market average. Real markups vary by domain, geography, urgency, and how many hoops you're willing to jump through. But the shape of the math holds.

Client pays $140. You see $83.78. That's roughly 40% of the original bill rate absorbed across three layers before it ever touches your engagement letter. Two layers, and you'd likely be closer to $95-100. One layer — a direct relationship with the prime or the client — and you could be north of $110.

Every layer added is a tax you pay for someone else's relationship, paperwork, or risk tolerance. Sometimes that's worth it. Often it isn't.

Why layers exist — and when they're actually justified

Not every layer is dead weight. A few legitimate reasons a sub or sub-sub exists:

• Vendor management systems (VMS): Large enterprises often restrict direct submissions to a closed list of preferred vendors. If your firm isn't on that list, it has to go through one that is.
• Risk and compliance carrying: Someone in the chain is carrying workers' comp, liability insurance, background check obligations, and payroll compliance. That's real cost, not pure profit.
• Specialized sourcing: A prime with a Fortune 500 relationship may genuinely lack the niche technical bench and need a specialist sub to find you.
• Speed: Sometimes an extra layer exists purely because that firm moved faster to fill a seat, not because they add value.

The problem isn't that layers exist. It's that most consultants never find out how many there are, or what each one is actually charging, until they're deep into a role and comparing notes with a peer who's billing the same client at a materially different rate.

The questions that expose the chain

You are allowed to ask about vendor structure. It is not rude, and any staffing partner worth working with will answer plainly. Bring these into your next screening call:

• "Am I contracting directly with the prime vendor, or is there another layer between you and them?"
• "How many companies are between the end client and my paycheck?"
• "Is this a direct placement with your firm's own client relationship, or a subcontract arrangement?"
• "If I'm extended or converted, does the vendor chain change, and does my rate change with it?"
• "Who actually manages my timesheet approval — the client, the prime, or someone further down?"

A vague or defensive answer is itself a data point. A firm that can clearly map its position in the chain — "we're the direct sub to the prime, no further layers" — is telling you something useful about how much of the rate is left for negotiation.

Bill rate vs pay rate: the number that actually matters

Stop asking "what's the bill rate." Start asking "what's my pay rate, and how many layers sit above me." The bill rate at the top of the chain is largely irrelevant to your paycheck if you're three layers removed from it. What matters is:

• Your actual pay rate (W-2 hourly, or the corp-to-corp rate if you're running your own entity)
• Your engagement model — W-2 with benefits load, 1099, or corp-to-corp with no withholding
• How many layers separate that number from the client's true spend

A staffing margin isn't inherently a bad thing — the firm placing you is doing real work: sourcing, compliance, payroll, client relationship management. The bad version is stacked margin across layers that add no visible value, with nobody telling you it's there.

The one takeaway to remember

Every layer between the client and you is a toll booth. Some tolls buy you something — insurance, access, speed. Others just buy someone else's rent. Your job isn't to eliminate layers on principle. It's to know exactly how many there are and ask, out loud, whether each one is earning its cut.

Consultants who ask about vendor structure upfront consistently negotiate better than those who find out after they've started billing. Bring it up before you sign, not after you compare notes with the guy sitting three desks over.
