The Recruitment Agency Margin Squeeze
Recruitment agencies operate on thin margins. A typical fee structure: client pays 15-25% of the candidate's first-year salary upon hire. A £50k placement yields £7,500-12,500 commission. Yet the sourcing and screening labour costs £3,000-5,000 per hire.
Why? A recruiter's workflow for a single placement: (1) Specification development (kickoff call with client, create job brief): 1-2 hours; (2) Candidate sourcing (LinkedIn, Boolean searches, direct outreach): 8-12 hours; (3) CV screening and shortlisting: 4-6 hours; (4) Interview scheduling and coordination: 2-3 hours; (5) Client feedback management: 1-2 hours; (6) Offer negotiation and onboarding coordination: 1-2 hours. Total: 17-27 hours per placement.
At a recruiter cost of £35k/year (loaded: £42k with employment costs), that's £20/hour. A 22-hour average placement costs £440 in labour. For 50 placements annually, that's £22,000 in labour cost—eating 30-40% of gross commission revenue.
The result: agencies hire junior recruiters (earning £25-30k) to handle volume, reducing placement quality and increasing attrition. Or they focus on high-ticket placements (£100k+ salary) to justify sourcing costs. Mid-market recruitment (£30-70k roles) becomes unprofitable at scale.
Recruitment Resourcing ≠ Headhunting: The Critical Distinction
Before exploring outsourcing, clarify the terminology. Recruitment resourcing and headhunting are often conflated; they are not the same.
Headhunting (Executive Search)
Headhunting: proactive identification and recruitment of senior executives (C-suite, VP-level, 6-figure roles). Headhunters build relationships over months, conduct discreet conversations, and negotiate packages. Fees: 25-35% of base salary (can exceed £50k per placement).
Headhunting requires domain expertise, network depth, and relationship-building skills. This is not outsource-friendly; it demands bespoke expertise and personal credibility.
Recruitment Resourcing (High-Volume Sourcing)
Recruitment resourcing: systematic sourcing, screening, and administrative coordination of candidates for mid-market roles (£20-80k salary). The workflow is standardized and repeatable. Resourcing coordinator roles can be taught and systematized.
Outsourced resourcing does not replace the recruiter's skill (client management, interviewing, deal-closing). It removes the administrative burden, freeing recruiters to do what they do best: relationships and placements.
The Admin Layer
Resourcing is the administrative layer between client brief and interview. Recruiters provide the commercial layer (client relationship, salary negotiation, offer closure). The two are separable.
Recruitment Resourcing Workflow and Tools
The Five Resourcing Functions
Boolean sourcing: using advanced LinkedIn and database searches to identify candidate pools. Boolean syntax (AND, OR, NOT operators) combined with filters (location, job title, experience) yields targeted candidate lists.
CV screening and shortlisting: reviewing candidate CVs against job specification, scoring for fit, and creating shortlist of 5-8 candidates for recruiter review.
Candidate outreach and engagement: messaging candidates on LinkedIn, making discovery calls to assess interest and availability, and managing candidate pipeline (responses, NOs, negotiation points).
Interview scheduling and logistics: coordinating candidate calendars, recruiter calendars, and client calendars; sending meeting invites; preparing interview briefs for recruiters.
ATS (Applicant Tracking System) management: logging candidates, tracking status (sourced, screened, interview, offer, placed), updating client dashboards, and maintaining data hygiene.
Tools and Platforms
LinkedIn Recruiter: native LinkedIn sourcing tool with Boolean syntax, saved searches, and InMail (direct message) capabilities. Cost: £500-1,500/month depending on team size.
Bullhorn: the industry-standard ATS for recruitment agencies. Tracks candidates, clients, job orders, and placements. Integrates with email and calendar. Cost: £50-100 per user/month.
JobAdder: lightweight ATS popular with SME agencies. Similar features to Bullhorn but lower cost. Cost: £30-60 per user/month.
ZoomInfo (formerly Apollo.io): database of 250M+ professional profiles with contact details, email, and company information. Cost: £100-400/month.
Calendly or Doodle: interview scheduling automation, reducing back-and-forth emails.
Resourcing Workflow Example: £50k Software Developer Role
Client kickoff: recruiter has 1-hour call with hiring manager, defines tech stack, experience level, salary range, location flexibility. Client provides 3-5 LinkedIn profile examples of 'ideal candidates.'
Resourcing coordinator performs Boolean search on LinkedIn Recruiter: (('Python' OR 'Java' OR 'Go') AND (6-8 years experience) AND (UK location OR remote) AND (SaaS OR fintech) NOT (contract NOT permanent)). Result: 200-300 matching profiles.
Coordinator reviews LinkedIn profiles, filters to 40-50 candidates matching seniority and company type fit. Sends LinkedIn InMail or email outreach (templated but personalized): 'We're recruiting a Python developer role at [client] for £50k base + benefits. Are you open to a conversation?' Expect 20-30% response rate.
Coordinator screens responses: 10-15 candidates confirm interest. Coordinator conducts brief discovery call (15 minutes) assessing salary expectations, notice period, and technical depth. Scores 5-8 as 'strong fit'.
Coordinator prepares shortlist: CVs, assessment notes, and salary expectations shared with recruiter for review.
Recruiter conducts 30-minute screening call with top 3-4 candidates, assesses culture fit and communication, and passes top 2 to client.
Coordinator schedules interviews: coordinates calendar invites, sends interview brief to candidates, sends candidate brief to hiring manager.
Interview happens (client conducts). Coordinator logs feedback, tracks offer status.
Offer made and accepted. Coordinator manages onboarding (background checks, offer letter, start date coordination).
Team Structure and Cost Comparison
A typical recruitment agency handling 40-60 placements annually uses this team structure:
Comparison
| Role | Responsibility | Typical Cost (Kenya) |
|---|---|---|
| Recruitment Resourcer (Lead) | Boolean search, sourcing strategy, CV screening QA, performance tracking, ATS management | £8,400/year (KES 1.26M) |
| Recruitment Resourcer (Junior) | Boolean searches, CV screening, candidate outreach, interview scheduling | £7,200/year (KES 1.08M) |
| Candidate Engagement Specialist | Discovery calls, candidate pipeline management, offer coordination, communication | £6,400/year (KES 960k) |
Total outsourced cost for a 3-person team: £22,000/year (KES 3.3M). A UK equivalent would cost £70-85k annually.
Cost Breakdown: UK vs. Nairobi
Comparison
| Line Item | UK (London) | Treba (Nairobi) | Saving |
|---|---|---|---|
| Senior Resourcer | £28-32k | £8,400 | £20-24k |
| Junior Resourcer | £22-26k | £7,200 | £15-19k |
| Candidate Engagement Spec | £20-24k | £6,400 | £14-18k |
| Subtotal (salaries) | £70-82k | £22,000 | £49-61k |
| Employer costs (20% + benefits) | £14-16k | £2,200 | £10-12k |
| Software (Bullhorn, LinkedIn Recruiter, ZoomInfo) | £8-12k | £4,000 | £4-8k |
| TOTAL ANNUAL COST (3-person team) | £92-110k | £28,200 | £63-81k |
Saving: £64-81k annually by outsourcing resourcing to Nairobi.
Cost per Placement
For an agency handling 50 placements/year: UK resourcing cost = £1,840 per placement. Nairobi resourcing cost = £564 per placement.
At £7,500 commission per placement (15% of £50k salary), UK labour cost consumes 24.5% of gross revenue. Nairobi outsourcing reduces that to 7.5%, improving margins by 17%.
Metrics, Quality Control, and Deployment
Key Performance Indicators (KPIs)
Submissions-to-interview ratio: for every 10 candidates screened by resourcer, how many get invited to interview by recruiter? Target: 30-50% (3-5 interviews per 10 submissions).
Interview-to-offer ratio: of candidates interviewed by client, how many receive offers? Target: 40-60% (indicates quality of screening).
Offer-to-placement ratio: of offers made, how many are accepted? Target: 80%+ (indicates market-competitive salary guidance).
Time-to-placement: from client brief to candidate start date. Target: 3-4 weeks for mid-market roles.
Cost-per-placement: total resourcer labour (hours × rate) ÷ placements. Target: £400-600 per placement.
Quality Assurance
Weekly screening audit: recruiter reviews a sample of CVs screened by resourcer (10-15% sample). Flags misses (strong candidates screened out) or poor fits (weak candidates advanced).
Monthly performance review: analyze metrics above. Adjust search parameters or screening criteria if interview-to-offer ratio is below 40%.
Candidate feedback: at offer or rejection stage, collect brief feedback from candidates ('Was the role description accurate?', 'Was communication professional?'). Logs inform process improvements.
Deployment and SLAs
- Phase 1: Onboarding (Week 1): Treba resourcers audit current job specs, client requirements, and ideal candidate profiles. Set up Boolean searches, ATS templates, and communication templates.
- Phase 2: Ramp (Weeks 2-4): Resourcers begin sourcing for 2-3 live job orders. Recruiter provides daily feedback on CV quality and screening accuracy.
- Phase 3: Steady State (Week 5+): Resourcers manage 5-8 concurrent open roles, producing 20-30 submissions per week. Standard SLA: 48-hour turnaround from job order to first batch of submissions.
Key takeaways
• Recruitment resourcing—sourcing, screening, scheduling—consumes 40-50% of recruiter time but generates no direct fee revenue.
It's pure cost. • Resourcing is distinct from headhunting: resourcing is administrative and systematizable; headhunting is relationship-based and requires expertise.
Outsource resourcing; retain headhunting in-house. • A 3-person outsourced resourcing team in Nairobi costs £28.2k annually vs. £92-110k in the UK—a saving of £64-81k per year. • Cost per placement: UK = £1,840; Nairobi = £564.
For a 50-placement agency, outsourcing improves gross margin by 17 percentage points. • Key metrics: submissions-to-interview ratio (target 30-50%), interview-to-offer ratio (40-60%), cost-per-placement (£400-600).
