The verdict in three sentences
A custom HRIS for a recruitment agency in Amsterdam in 2026 costs 45,000 to 120,000 EUR, covering candidate management, assignment tracking, billing and payroll connection. The project runs 14 to 24 weeks with 15%/year maintenance. The ROI comes from recruiter productivity: an equipped consultant handles 20 to 40% more assignments at the same headcount.
Scope of an agency HRIS and budget
A recruitment agency has different needs from a corporate HR department: it manages a flow of candidates, client assignments, placements and related billing. The HRIS must cover the whole chain, from sourcing to payment.
| Module | Scope | 2026 order of magnitude (EUR) |
|---|---|---|
| Candidate management / talent pool | Profiles, matching, history, GDPR | 10,000 - 26,000 |
| Assignment tracking | Roles, clients, pipeline, KPIs | 8,000 - 22,000 |
| Billing and fees | Quotes, invoices, schedules, reminders | 8,000 - 22,000 |
| Payroll / contracting link | Contracts, variables, payslips | 8,000 - 24,000 |
| Client / candidate portal | Tracking, documents, signatures | 6,000 - 16,000 |
| Reporting and steering | Margin per assignment, fill rate | 5,000 - 16,000 |
Off-the-shelf or custom HRIS
Generalist HRIS (PayFit, Lucca) cover payroll and internal admin but not the placement business. Market ATS cover recruiting but rarely billing and contracting.
| Criterion | Market tools (stacked) | Custom HRIS |
|---|---|---|
| Year 1 cost | 8,000 - 25,000 EUR/year | 45,000 - 120,000 EUR |
| Full business chain | Fragmented (2-4 tools) | Unified |
| Double entry | Frequent | Eliminated |
| Assignment-linked billing | Rare | Native |
| Process customisation | Weak | Full |
| Data / code ownership | No | Yes |
Custom is justified when the tool stack creates double entry and margin per assignment depends on processing speed.
Mini case study
Elodie, head of an Amsterdam recruitment agency, employs 8 recruiters who each place on average 11 assignments/month, with an average fee of 6,500 EUR per placement. She invests 78,000 EUR in a custom HRIS, plus about 11,700 EUR/year maintenance.
By removing double entry and automating matching, each recruiter gains 30% capacity, rising to ~14 assignments/month. Across 8 recruiters that is ~24 additional placements/month, potentially 288/year. Even converting only a quarter of that capacity into real placements (72/year) at 6,500 EUR, additional revenue reaches ~468,000 EUR/year. The HRIS repays in under 3 months on a conservative assumption.
