The verdict in three sentences
For an HR consulting and recruitment firm, the 2026 trade-off pits a market ATS/CRM at 60-150 EUR/consultant/month against a custom platform at 40,000-90,000 EUR excl. VAT. Custom is justified when the firm wants to unify candidate pool, assignment tracking, staffing and billing in its own flow. Below 15 consultants, the market subscription stays cheaper; beyond that, the break-even tips toward custom within 2 to 3 years.
Modules of an HR firm platform
A firm doesn't buy a plain ATS. It buys the link between candidate sourcing, assignment staffing and client billing. Here are the key modules and their indicative custom cost.
| Module | Indicative cost (EUR excl. VAT) | Role |
|---|---|---|
| Candidate pool / ATS | 10,000 - 20,000 | Sourcing, scoring, history |
| Assignment and client CRM | 8,000 - 16,000 | Sales pipeline, accounts |
| Staffing / allocation | 7,000 - 15,000 | Consultants on assignments, workload plan |
| Assignment and time tracking | 6,000 - 14,000 | Time spent, milestones, profitability |
| Billing and fees | 6,000 - 12,000 | Time & materials, fixed, success fee |
| Management reporting | 4,000 - 9,000 | Margin per assignment, utilization rate |
Custom makes full sense when recruitment success-fee billing and consulting time & materials coexist: few market tools handle both models well at once.
Break-even by headcount
The right question isn't the sticker price but the break-even by number of consultants. A per-seat subscription costs little at 8 consultants, a lot at 40. 2026 order of magnitude, over 3 years.
| Headcount | Market ATS/CRM (100 EUR/mo/consultant, 3 yr) | Custom (60,000 EUR + 9,000/yr) |
|---|---|---|
| 8 consultants | 28,800 EUR | 87,000 EUR |
| 15 consultants | 54,000 EUR | 87,000 EUR |
| 25 consultants | 90,000 EUR | 87,000 EUR |
| 40 consultants | 144,000 EUR | 87,000 EUR |
| 60 consultants | 216,000 EUR | 87,000 EUR |
The crossover sits around 20 to 25 consultants: below, subscription wins; above, custom becomes clearly cheaper while offering a flow 100% tailored to the firm.

Mini case study
Sophie, managing partner of an HR consulting and recruitment firm of 32 consultants, currently pays a market ATS/CRM 100 EUR/consultant/month, i.e. 38,400 EUR/year. She invests 68,000 EUR excl. VAT in a custom platform (pool, assignment CRM, staffing, T&M + success-fee billing).
Three-year market cost: 115,200 EUR. Custom cost: 68,000 EUR + 27,000 EUR maintenance = 95,000 EUR. Direct saving: about 20,000 EUR over 3 years, plus a better consultant utilization rate and faster billing (fewer missed success fees), i.e. tens of thousands of euros of additional margin.
FAQ
From what headcount is custom profitable? Around 20 to 25 consultants. Below that, a market ATS/CRM at 60-150 EUR/seat/month stays cheaper and faster to deploy.
Does a market ATS handle time & materials and success fee? Rarely both with finesse. A firm mixing consulting (T&M/fixed) and recruitment (success fee) is often the best candidate for custom.
How long to deploy the platform? Expect 4 to 6 months: scoping staffing and billing processes, development, candidate pool migration and consultant training.
Can the platform connect to job boards and LinkedIn? Yes, via API and connectors. Multi-channel sourcing feeds the pool, with deduplication and candidate scoring.
What annual maintenance budget should you plan? Between 7,000 and 12,000 EUR/year for hosting, candidate data security (GDPR), support and functional upgrades.
