Temp-to-Hire Conversion: What It Costs to Bring a Staffed Trade Worker on Payroll
You found a welder or electrician on assignment you don't want to lose. Here's how conversion fees actually work before you make an offer.

Most skilled-trades staffing agreements let you hire a staffed worker directly, but a conversion (buyout) fee applies. Fees are usually structured as a flat percentage of annual pay or a sliding scale that declines the longer the person has worked your assignment, often reaching zero after a set number of hours or months.
Why This Conversation Always Happens Mid-Project
It plays out the same way on almost every job. A staffed pipefitter or electrician shows up, works clean, doesn't need hand-holding, and by week four your superintendent is asking if you can just "bring him on" before the assignment ends. Nobody plans this moment — it happens because the worker is good, not because anyone read the staffing agreement first.
That's exactly where cost surprises live. The decision to convert a staffed worker to your own payroll feels like a simple HR move, but it's governed by a clause you signed months earlier and probably didn't think about again until now.
How Conversion Fees Are Actually Built
A staffing agency's bill rate is priced to recover its cost of sourcing, screening, payrolling, and insuring a worker over the expected length of an assignment. If you pull that worker onto your own payroll early, the agency hasn't recovered what it spent to place them — that's the entire reason conversion (also called buyout or direct-hire conversion) fees exist. This is a standard mechanic across the staffing industry generally, not something unique to any one firm.
There are two common fee structures worth knowing before you're mid-negotiation. The first is a flat fee — a set dollar amount or a flat percentage of the worker's projected first-year pay, charged regardless of how long they've been on assignment. The second, more common on longer projects, is a declining sliding scale: the fee is highest if you convert someone in week two and shrinks the longer they've worked your assignment, often reaching zero once they cross a defined threshold — a certain number of hours worked or a set number of weeks on assignment.
A Worked Example (Hypothetical Numbers)
Say your staffing agreement has a 90-day declining scale that starts at a percentage of the worker's estimated first-year pay and steps down by roughly a third every 30 days, hitting zero after 90 days on assignment. If you convert that welder in week two, you're near the top of the scale. If you wait until week eleven, the fee has already stepped down twice. If the assignment runs past the 90-day mark, the conversion may cost nothing at all.
The exact percentages, thresholds, and step-downs vary by agency and by trade — a certified welder with a hard-to-fill ticket may carry a different schedule than a general helper — so treat this example as a way to understand the shape of the deal, not a number to quote back to anyone.
What the Fee Is Actually Covering
The fee isn't a penalty for wanting to hire someone — it's recovery of real cost the agency already carried. That includes sourcing and screening the worker, verifying certifications and licenses before they ever hit your site, running the drug and background checks your safety program requires, and carrying unemployment insurance and workers' comp exposure while the person was on the agency's payroll.
It also covers the agency's lost future margin. Every week that worker stays on assignment is billable revenue the agency built its business plan around. Pulling them onto your payroll early cuts that revenue off — the conversion fee is how the two sides settle that early exit without one party absorbing the whole cost.
Lock the Terms In Before You Fall in Love With a Worker
The best time to negotiate conversion terms is before you sign the staffing order — not after you've already decided you want to keep someone. Ask for the declining-scale schedule in writing, in plain numbers, before the first person shows up on your jobsite. Ask specifically what hour count or date makes conversion free, since that number should shape how you plan your hiring conversations, not the other way around.
If you already know a project has a strong chance of converting good performers to permanent roles — a plant that's rebuilding its maintenance department, for example — say so up front. Agencies price and structure orders differently when they know conversion is the plan rather than the exception, and you'll get cleaner terms than trying to negotiate after the fact.
The Real Risk of Going Around the Fee
Some contractors try to shortcut this by having the worker resign from the agency and come back a week later as a direct hire, or by routing the offer through a different entity. Staffing agreements typically include language that closes this gap — a hire-around clause that treats any hire within a defined window of the assignment ending the same as a direct conversion, fee included.
Beyond the contract risk, there's a relationship cost. Agencies remember who tried to work around a fee versus who negotiated it honestly, and that shows up the next time you need six pipefitters on 48 hours' notice. It's a small industry — the trades staffing world in a given metro is smaller still — and the contractor who plays it straight on conversions is the one who gets first call on the next hard-to-fill order.
Frequently asked
Is there always a conversion fee for hiring a staffed trades worker directly?
In almost every skilled-trades staffing agreement, yes — some fee structure applies if you hire a staffed worker onto your own payroll before or shortly after their assignment ends. The size and structure of that fee vary by agency and by how long the worker has been on assignment, but the concept itself is close to universal in the staffing industry.
Does the conversion fee really shrink the longer someone works as a temp?
Most agreements are built this way, using a declining sliding scale tied to hours worked or weeks on assignment. The logic is straightforward: the longer a worker stays on assignment, the more the agency has already recovered its sourcing and carrying costs, so the buyout amount needed to make the agency whole gets smaller over time, often reaching zero after a defined threshold.
Can we negotiate the conversion fee before we even place the order?
Yes, and this is the best time to do it. Once you're attached to a specific worker, you have far less negotiating leverage. Raise the topic when you're writing the staffing order — ask for the fee schedule in writing, ask what threshold makes conversion free, and if you expect a project to lead to permanent hires, say so up front so the order is priced accordingly.
What actually happens if we just hire the worker without paying the fee?
Most staffing agreements include a hire-around clause that treats indirect hiring — having the worker resign and return as a direct hire, or routing the offer through another entity — the same as a direct conversion, with the fee still owed. Beyond the contract exposure, skipping the fee tends to damage the working relationship with the agency, which can affect how quickly they respond the next time you need a crew on short notice.
