The verdict in three sentences
For a recruitment agency, a SaaS ATS (EUR 50-150/recruiter/month) starts fast and covers the standard pipeline, but it often splits sourcing, tracking and mission billing. A custom ATS (EUR 40,000-100,000) unifies those three worlds and integrates your jobboards and LinkedIn your way. The central gain: 20-30% of sourcing time returned to recruiters who cost a lot.
SaaS or custom: where the value is
SaaS is perfect for a small agency or a standard need. Once multi-channel sourcing, success/retainer billing and reporting become strategic, custom removes double entry and fits your business model.
| Criterion | SaaS ATS | Custom ATS |
|---|---|---|
| Entry cost | EUR 0-5,000 (setup) | EUR 40,000-100,000 |
| Monthly cost | EUR 50-150/recruiter | Hosting EUR 250-700/mo |
| Timeline | 2-6 weeks | 4-7 months |
| Multi-channel sourcing | Standard | Own rules and scoring |
| LinkedIn/jobboard integration | Limited connectors | Custom |
| Mission billing | Often external | Built in (success/retainer) |
| Candidate GDPR | Vendor-dependent | Designed custom |
| Code ownership | No | Yes |
3-year TCO for a 10-recruiter agency
Same scope (sourcing, pipeline, billing, reporting). 2026 orders of magnitude.
| Line item | SaaS ATS (EUR 95/rec.) | Custom |
|---|---|---|
| License / initial build | EUR 0 | EUR 70,000 |
| Subscription 10 recruiters / yr | EUR 11,400 | EUR 0 |
| Hosting + monitoring / yr | included | EUR 5,400 |
| Maintenance / changes / yr | included | EUR 10,500 |
| External billing tool / yr | EUR 3,600 | included |
| 3-year total | EUR 45,000 | EUR 117,700 |
SaaS stays cheaper on cash over 3 years at this size. But custom becomes attractive once the sourcing time saved converts into extra placements, which TCO alone doesn't show.
Mini case study
Nadia, managing partner of a recruitment agency in Paris, employs 10 recruiters at a fully loaded EUR 65/h. Each spends ~14 h/week on sourcing. A custom ATS (scoring, dedup, jobboard integration) saves 25%, i.e. 3.5 h/recruiter/week = 35 h/week for the agency, ~1,540 h/year, valued at ~EUR 100,000/year. Even if only a third converts into extra billed placements (~EUR 33,000 margin), amortizing a EUR 70,000 build over 3 years (EUR 23,300/yr) plus EUR 15,900 running costs is covered from year two.

What does a custom ATS cost in 2026?
Between EUR 40,000 and 100,000 depending on sourcing depth, jobboard integration and mission billing. A first operational pipeline often ships around EUR 45,000-55,000.
Isn't SaaS enough for a small agency?
Often yes, under 5-6 recruiters with standard processes. Beyond that, the sourcing/billing split and integration limits justify custom.
What real sourcing-time gain?
20-30% with good scoring, candidate deduplication and LinkedIn/jobboard integration. On a 10-recruiter agency that is often 1,200-1,800 hours/year.
How do we handle candidate GDPR?
Retention periods, consent, right to erasure and traceability must be built in from design. Custom handles them natively instead of relying on a vendor's settings.
Can we integrate our existing jobboards?
Yes, via API or multiposting. A custom ATS centralizes posting and pulls applications into one pipeline, with no double entry.
