The verdict in three sentences

A custom ATS/CRM links sourcing, candidate pipeline, assignments and success-based invoicing, where a recruitment agency stacks spreadsheets and disconnected tools. In 2026, budget 45,000 to 120,000 EUR excl. tax for custom, versus 60 to 120 EUR/user/month for a SaaS ATS. The return shows in the placement rate, up 10 to 20 % thanks to matching and a smooth pipeline.

SaaS ATS vs custom: the 3-year math

A SaaS ATS bills per user. For a growing agency, the bill climbs while customization stays capped.

CriterionCustomSaaS ATS
Upfront cost45,000 - 120,000 EUR excl. tax2,000 - 6,000 EUR (setup)
Monthly cost700 - 1,800 EUR (maintenance)60-120 EUR/user
3-year cost, 10 consultants70,200 - 184,800 EUR23,600 - 53,200 EUR
3-year cost, 30 consultants70,200 - 184,800 EUR66,800 - 155,600 EUR
Specific matching & workflowTotalLimited to standard
Candidate database ownershipYouVendor

Below 10 consultants, a SaaS ATS is cheaper. Above 25 to 30 consultants, or for a specific matching process, custom becomes competitive and makes you the owner of your candidate database, your main asset.

Modules of a recruitment ATS/CRM

An agency runs three flows: candidates, client assignments and money. Each module attacks a friction point.

ModuleWhat it solvesCustom range 2026 (EUR excl. tax)
Sourcing & candidate databaseCentralizes CVs, parsing, duplicates8,000 - 20,000
Candidate/assignment matchingSuggests best profiles10,000 - 25,000
Pipeline & assignment trackingVisualizes progress per role8,000 - 18,000

Success-based invoicingTriggers invoice on placement6,000 - 15,000
Reporting & consultant KPIsRevenue, conversion tracking6,000 - 14,000

Delivery takes between 5 and 8 months, going live with the candidate and pipeline core first.

ROI per consultant: what +10 to +20 % placements is worth

In an agency, every extra placement per consultant converts directly into fees. Matching and a smooth pipeline raise that volume.

Mini case study

He invests 90,000 EUR excl. tax in a custom ATS/CRM with matching, pipeline and success-based invoicing. Within a year, placements per consultant climb 15 % (+1.8), adding 324,000 EUR of revenue, plus 40,000 EUR in saved admin hours. Total gain: 364,000 EUR, project paid back in 3 months, and he keeps ownership of his candidate database.

FAQ

How much does a custom ATS/CRM cost in 2026?

Between 45,000 and 120,000 EUR excl. tax depending on modules. A sourcing + pipeline core starts at 45,000 EUR; a full platform with advanced matching and a client portal exceeds 100,000 EUR.

Isn't a SaaS ATS enough?

Below 10 consultants, often yes. Above 25 consultants, SaaS per-user cost approaches custom over 3 years, without making you the owner of your candidate database.

What does custom matching add?

It ranks candidates by relevance on your business criteria (skills, mobility, pay), cutting shortlist time and raising placement rate by 10 to 20 %.

How does success-based invoicing work?

The invoice is triggered automatically on a confirmed placement, computing fees (percentage of annual salary or flat fee). This avoids omissions and speeds up collection.

Can LinkedIn and job boards be integrated?

Yes, via API and connectors. We integrate multi-channel sourcing (job boards, LinkedIn, careers site) to feed the candidate database automatically without re-keying.
