Should a trades business hire an in-house recruiter or use a recruiting partner?

It comes down to volume. A full-time recruiter is a fixed salary-plus-overhead cost that only pays for itself when there's steady, year-round hiring to keep them busy — typically the territory of shops running many trucks or multiple locations. A recruiting partner is a variable cost that scales with hires, which fits the seasonal, lumpy hiring pattern of most HVAC and plumbing businesses.

How much does an in-house recruiter cost compared to a recruiting partner?

An in-house recruiter costs their full salary plus benefits, payroll taxes, and the tools they need — job board budgets, an applicant tracking system, sourcing subscriptions — and that cost runs whether they make one hire or twenty. A partner typically charges per hire or a recurring pipeline fee, so the cost tracks the hiring you actually do. At low volume the partner is cheaper per hire; at high sustained volume the salary spreads thin enough to win.

How many hires a year justify a full-time recruiter?

There's no magic number, but the test is simple: would the recruiter be busy every week of the year? Divide their total annual cost by your realistic yearly hires and compare that per-hire figure to a partner's fee. If hiring is concentrated in a busy season or averages a hire every month or two, a full-time seat spends much of the year underused and the math favors a partner.

Can a recruiting partner really know my trade well enough?

A generalist agency often can't — trades hiring lives on license levels, certifications, and whether someone can actually run a service call. A trades-focused partner works these roles across many shops at once, which means an active bench of screened techs and current knowledge of local pay. That pooled pipeline is something a single in-house recruiter has to build from zero.

What about having the office manager do recruiting part-time?

It's the default in most shops, and it works until hiring becomes constant. Recruiting done in the gaps between dispatch and invoicing means slow responses, and in a market where good techs accept the first offer that moves, slow response is how seats stay open. Part-time attention is fine for the occasional hire; steady hiring needs dedicated capacity, whether that's a seat you own or a partner you pay.

In-house recruiter vs. recruiting partner: when should a trades business hire its own recruiter?

Should you hire your own recruiter or bring in a recruiting partner?

Hire an in-house recruiter when you have enough year-round hiring to keep a full-time person busy every week; use a recruiting partner when hiring is real but lumpy — which describes most trades businesses under several dozen employees. The decision is a cost-structure question, not a quality question: a recruiter seat is a fixed cost you pay whether or not you're hiring that month, while a partner is a variable cost that tracks your actual hires. Get the volume math right and the answer usually falls out on its own.

This piece assumes you've already ruled out doing nothing and ruled out temp staffing — if you're still weighing those lanes, start with recruiting service vs. staffing agency vs. in-house. Here we're on the narrower question that comes after: you know you need dedicated recruiting capacity, and you're deciding whether to own it or rent it.

The real cost of a recruiter seat

The salary line is the visible part. In-house recruiter salaries commonly run in the range of a mid-level office professional — often not far off what you pay a licensed tech — and the full cost of the seat stacks on top of it:

Cost component	Notes
Base salary	The visible line — comparable to skilled office staff
Benefits + payroll taxes	Adds a meaningful percentage on top of base
Job board + sponsorship budget	The recruiter still needs to post and sponsor jobs
Tools (ATS, sourcing, texting)	Software the role can't function without
Management time	Someone has to direct, review, and cover their PTO
Ramp time	Months before a new recruiter knows the trade and the market

And one more that doesn't fit in a table: the recruiter is a hire too. You're taking on time-to-fill risk and bad-hire risk on the very role that's supposed to reduce both. SHRM's replacement-cost research puts direct costs at 50–60% of an employee's annual salary, and total costs at 90–200% — that applies to a recruiter who washes out at month eight just like it applies to a tech.

The real cost of a partner

A recruiting partner charges either per hire (a flat or percentage fee) or a recurring subscription that keeps a pipeline warm. Percentage-of-salary contingency fees are the traditional agency model; flat-fee and subscription models have become common precisely because percentage fees sting on repeat hires. The full pricing landscape is covered in how much a recruiter costs — the structural point here is simpler:

	In-house recruiter	Recruiting partner
Cost shape	Fixed — runs 12 months a year	Variable — tracks hires
Cost when hiring stops	Full seat cost continues	Drops to zero or a small retainer
Cost at high volume	Spreads thin — gets cheap per hire	Stacks per hire
Ramp time	Months to learn the trade	Days — already in the market
Candidate bench	Built from zero, yours alone	Pooled across many shops
Loyalty and context	Fully yours, on-site	Shared; depends on the partner
Risk	It's a hire — can be a bad one	Fee wasted if the partner is weak

The break-even math

Run it on a napkin. Take the full annual cost of the seat — salary, the benefits and tax load, tools, board spend — and divide by the hires you honestly expect this year. Not the hires you'd make in a dream expansion; the ones on your actual plan. Compare that number to a partner's per-hire fee.

For context, SHRM pegs the average cost per hire around $4,700 across industries — and that figure famously undercounts the internal time that a fixed seat represents. A shop making four or five hires a year is paying a multiple of any partner fee once the seat cost is divided across so few hires. A shop making a hire every couple of weeks, year-round, flips the math: the fixed cost spreads across enough hires that owning the capacity wins.

Two adjustments before you trust the napkin:

Utilization is the killer variable. Trades hiring is seasonal and lumpy. If your recruiter is flat-out in spring and idle in November, you're paying twelve months for seven months of work. Partners absorb that lumpiness because they're smoothing demand across many clients.

Speed has a price you don't see on the invoice. Skilled trades roles average 56 days to hire, and every one of those days is missed revenue on a truck that isn't rolling. A new in-house recruiter starts that clock from zero on their first search; a trades-focused partner starts with a bench. If the partner fills seats meaningfully faster, that difference is worth real money before you compare a single fee.

When each one clearly wins

Hire in-house when: you're running enough trucks or locations that hiring never stops; you want recruiting embedded in daily operations and culture; you have someone to manage the function; and the per-hire math above actually beats the fees. At that scale, an owned seat also compounds — the recruiter's local network and employer brand work belong to you.

Use a partner when: hiring is steady but not weekly; you can't afford a seat that idles off-season; you need someone productive this month, not next quarter; or your last "recruiter" was the office manager's spare time. If you go this route, the follow-on choice is how much of the work you keep — done-for-you vs. done-with-you hiring breaks that down.

The hybrid worth knowing: shops at the boundary often keep coordination in-house — an office lead who owns scheduling and onboarding — and rent the sourcing and screening from a partner. You get responsiveness without paying for a full sourcing capability that idles half the year. What you're really buying either way is dedicated attention, because whoever does this job has to move fast: in this market, speed to lead decides who gets the tech.

Bottom line

Own the recruiter when volume keeps them busy every week; rent the capability when it doesn't. Most trades businesses hit constant-hiring scale later than they think, and pay for an underused seat in the meantime — or worse, assign hiring to nobody in particular and wonder why seats stay open. HireAligned is the partner side of this trade-off: a warm pipeline of pre-screened, culture-fit techs, priced to scale with your hiring instead of your payroll. See how done-for-you hiring works.
