A construction recruiting fee should be calculated on a base defined in writing before you sign. Some firms bill on base salary, others on total first-year compensation including bonuses, and the same percentage produces materially different invoices. The percentage is what gets negotiated. The base is what decides the number.
Two contractors sign with the same recruiter at the same 20 percent. Both hire a project manager on a $150,000 base salary with a $30,000 target bonus. One gets an invoice for $30,000 and the other for $36,000. Neither of them negotiated badly. One of them read a definition and the other assumed one.
Six thousand dollars on a single hire is a rounding error against a project budget. Run four senior searches a year for three years and the same unread clause is worth more than most contractors spend evaluating recruiters in the first place.
This is the clause that gets skipped because it looks administrative. It sits below the percentage, it is written in the flattest possible language, and it is the only number in the agreement that changes the invoice without anyone appearing to change the price.
Is a construction recruiting fee based on base salary or total compensation?
Both exist and the agreement decides which. Base salary produces the smaller invoice. Total first-year compensation, which can sweep in bonus, commission, equity and allowances, produces the larger one. Ask before signing and get the answer in the document, not the sales call.
The reason this is not settled by convention is that there is no convention. The percentage has one: most US firms sit between a fifth and a quarter of first-year pay. The base has never converged the same way, and the wider a firm’s definition, the more the headline percentage understates what you will actually pay.
Which produces a specific negotiating trap. A firm quoting 18 percent on total compensation is more expensive than a firm quoting 20 percent on base salary, on the same hire, and the quote that looks cheaper is the one that costs more. If you are comparing recruiters on percentage alone, you are comparing the part they chose to make comparable.
What should the fee base include beyond base salary?
A defensible base is narrow, written down, and readable by both sides the same way. It should capture compensation that is contractually certain at the point of offer and exclude everything that is discretionary, variable, or not cash.
Ours, stated so you can benchmark against it: fees are calculated on first-year cash compensation, meaning base salary, plus any contractual or target bonus stated in the offer letter, plus any signing bonus. Discretionary bonus, commission, equity, allowances and benefits are excluded. Where the bonus is discretionary, the fee is computed on base salary plus the signing bonus.
The logic of that line is worth spelling out, because the exclusions are the part that matters. A discretionary bonus is not a commitment to the candidate, so billing you for it charges a fee on money that might never be paid. Commission and equity are not knowable at offer. Allowances and benefits are cost of employment, not compensation to the individual. Anything in that list widens the base without widening what the candidate actually receives in year one.
| Fee base | On a $150,000 base with a $30,000 target bonus | What can drift |
|---|---|---|
| Base salary only | 20% = $30,000 | Nothing, but a real contractual bonus goes uncaptured |
| First-year cash compensation | 20% = $36,000 | Fixed at offer, both sides can compute it |
| Total compensation, undefined | 20% of an unbounded number | Vehicle allowance, benefits load, projected commission |
The third row is the one to avoid, and it is avoided by asking a single question: what exactly is in the number you will multiply by the percentage?
Why does the fee base cause more disputes than the percentage?
Because the percentage is agreed at signing and the base is discovered at invoicing. By the time the two readings diverge, the candidate has started, the seat is filled, and your negotiating position is gone. The dispute is not about fairness. It is about sequence.
Everything about the timing works against you. You read the agreement when the search is a hypothetical, and you read the invoice when the hire is a fact. Between those two moments the recruiter has delivered the thing you wanted, which is precisely when arguing about six thousand dollars feels least worth it.
That asymmetry is why the correct time to argue is before the search starts, when the fee is abstract and the leverage is symmetrical. The base is one of several terms worth negotiating at that point, and running the same search through three firms at once makes every one of them harder to enforce. A recruiter who will not define the base in writing at that point is telling you what the conversation will look like later.
It also explains a pattern worth naming: contractors who dispute an invoice usually cannot point to the clause they are disputing, because there is not one. The absence is the defect. A document that never defines the base has not left the question open, it has decided it in the drafter’s favor.
What to ask, and when
Ask before the search starts. Five questions, all answerable in a sentence, all belonging in the agreement rather than an email thread:
- What is the base the percentage applies to? Get the definition, not the word “compensation.”
- Are bonuses included, and which kind? Contractual and target bonuses behave differently from discretionary ones.
- Are equity, commission, allowances or benefits in the number? All four are common quiet inclusions.
- What happens if the candidate’s package changes between offer and start? Rare, but it happens on negotiated packages.
- Is there a minimum fee? A minimum can make a modest hire cost like a large one regardless of the base.
Those questions are also a competence test, not only a commercial one. A firm that answers all five without checking has thought about its own paperwork. A firm that improvises the answers is improvising the search too.
Market context, so the numbers have somewhere to sit: federal wage data puts the national median for construction managers, SOC 11-9021, at $114,990, and for cost estimators, SOC 13-1051, at $78,740, both as of May 2025 (BLS OEWS and cost estimators). Of the 1,041 firms answering the salaried-hiring question in the 2025 AGC workforce survey, 91.7 percent reported difficulty filling salaried positions, and monthly hiring and separations data is published in BLS JOLTS. Those are national medians, and the packages that trigger this argument sit well above them: in the metro markets across Texas and the Southeast where commercial building is busiest, senior preconstruction and project leadership routinely clears the national figure by a wide margin. At those compensation levels, a few points of undefined base across several hires a year is not a detail.
Who this does not apply to
Contractors who already have a signed agreement with the base defined and have never had an invoice surprise do not need this. The clause is doing its job and there is nothing here to fix.
It also does not apply to trades, craft labor or temporary field staffing, where the fee structures are different. Selah Talent Partners does not work in those markets.
And it is not an argument for the narrowest possible base in every case. A contractor negotiating a base-salary-only fee on a role with a large contractual bonus is asking a recruiter to work a $200,000 package for a $150,000 fee calculation, and that shows up later as reduced appetite for the search. The goal is a base both sides can compute and neither side resents.
Our published Contingency Search rate is 20 percent of first-year cash compensation as defined above, payable only when a Selah-sourced candidate starts, with a 120-day replacement guarantee. That definition is in the agreement from day one, including on a confidential executive search for mandates that cannot be publicly posted, where the fee base is the last thing anyone wants to be arguing about. The full terms are on pricing, and what to ask a construction recruiter before you sign covers the rest of the agreement.
So the question to take into your next recruiter conversation is not what percentage they charge. It is what they multiply it by, and whether they will write it down.
