Every growing organization eventually faces the same question: do we build the hiring capability internally, or do we partner with someone who already has it built? Most leadership teams answer this with a spreadsheet, comparing an internal cost-per-hire against an agency fee percentage, and pick whichever number looks smaller. That comparison, while intuitive, is also the reason so many organizations get this call wrong.
The Number Everyone Looks At First
Start with the numbers that usually drive the conversation. According to SHRM’s 2025 Recruiting Benchmarking Report, the average internal cost per hire sits around $4,700. Staffing agency fees typically run 15 to 35 percent of a hire’s first-year salary, which for a mid-level professional role can mean $15,000 to $35,000 per placement.
Looked at side by side, internal hiring appears to win decisively, and for many organizations facing steady, predictable hiring volume, it genuinely does.
The Real Number: The Cost of an Empty Seat
The more useful question isn’t what a hire costs. It’s what an empty seat costs. A senior technical role generating meaningful output value doesn’t produce that value while the position sits vacant, and the team around that seat absorbs the slack in the meantime.
This reframes the build-versus-partner decision away from a pure cost question and toward a speed and risk question. For roles with deep, readily available candidate pools, internal recruiting can be the more efficient path.
Where the Line Actually Sits
A few patterns show up consistently across organizations that have worked through this decision carefully.
Volume Matters
Organizations making fifteen or more hires a year in a given function tend to see stronger economics from building an internal team.
Urgency Changes The Math
When a role needs to be filled quickly, the cost of waiting for an internal search can outweigh a fee differential.
Specialization Matters
Deep technical, executive or industry-specific roles can require networks that internal teams have not had the reason to build.
Confidentiality & Flexibility
Confidential executive searches and contract or project-based roles can favour external partners.
Why This Is a Leadership Question, Not a Procurement One
The mistake many organizations make is routing this decision through whoever owns the recruiting budget and treating it as a line-item comparison.
The real question underneath it isn’t “which option costs less on paper.” It’s “where does this business want to carry risk, and how fast does it need to be able to move.”
What This Means Right Now
This calculation is worth revisiting today specifically, not as a routine annual exercise. Canada’s labour market has shifted twice in the span of two months, from a two-year unemployment low in July to a 42,000-job pullback in August, against a backdrop of escalating trade tensions reshaping hiring plans across trade-exposed sectors.
For leadership teams that haven’t revisited their build-versus-partner assumptions recently, the honest starting point isn’t which model is cheaper in the abstract. It’s an audit of where the business is actually carrying risk right now, which roles are sitting open longer than they should, and whether the current hiring model matches the speed the business genuinely needs heading into the next two quarters.
