The verdict in three sentences
An HR firm living in spreadsheets and a generic ATS adapts poorly to its processes (multi-role searches, talent pool, assignment tracking, success-fee billing) and loses placements to slow response. A custom ATS + candidate CRM — sourcing, assignment tracking, billing, data compliance — costs between 30,000 and 80,000 EUR in 2026 and pays back through admin time saved and extra placements. The choice is between a per-recruiter SaaS ATS and a backbone that fits exactly how you work.
What a recruitment backbone covers in 2026
The core of a firm is the candidate-assignment pipeline and its billing. Typical modules and orders of magnitude:
| Module | Scope | 2026 order of magnitude (EUR) |
|---|---|---|
| ATS / candidate pipeline | Talent pool, stages, role matching | 8,000 - 20,000 |
| Client & assignment CRM | Accounts, needs, sales tracking | 6,000 - 16,000 |
| Sourcing & multiposting | Job posting, forms | 5,000 - 12,000 |
| Success-fee / retained billing | Fees, milestones, credit notes | 6,000 - 14,000 |
| Candidate data compliance | Consent, purge, audit log | 4,000 - 10,000 |
| Testing, migration, training | Pool migration, onboarding | 4,000 - 10,000 |
A realistic timeline is 12 to 18 weeks, functional MVP at around 8-10 weeks.
SaaS ATS vs custom
Market ATS platforms charge per recruiter/month; custom is an investment plus maintenance. For a growing firm, the comparison is telling.
| Criterion | SaaS ATS | Custom backbone |
|---|---|---|
| Entry cost | 0 - 3,000 EUR setup | 30,000 - 80,000 EUR |
| Recurring cost | 60 - 150 EUR / recruiter / month | 400 - 1,000 EUR/month maintenance |
| Success-fee billing | Often absent | Native, tailored |
| Specific matching / scoring | Standard | 100% tailored |
| Candidate compliance (auto purge) | Variable | Framed by your rules |
| Data ownership | Vendor | Firm |
For 10 recruiters at 100 EUR/month, the SaaS ATS costs 12,000 EUR/year in licenses, excluding billing modules. Custom becomes competitive from year 2-3 while natively integrating success-fee billing, often missing from standard ATS platforms.
Mini case study
Julien runs a recruitment firm in Amsterdam (8 consultants). Each consultant lost about 6 hours/week re-keying between ATS, tracking spreadsheet and billing — 48 hours/week combined. He invests 52,000 EUR in an ATS + CRM + billing backbone, maintenance 650 EUR/month.
After rollout, admin time drops by 30% — about 14 hours/week returned to sales, valued at 45 EUR/hour: about 2,500 EUR/month of recovered capacity. Converted into extra placements (an average placement generates several thousand euros of fees), the additional margin pays back the project in around 18 months.
