The verdict in three sentences
A custom platform uniting ATS, CRM, time tracking and billing for a consulting/HR firm costs between EUR 35,000 and 95,000 in 2026. The timeline is 4 to 7 months, with EUR 500 to 1,200/month of maintenance. The lever is twofold: +20 to 30% productivity for consultants/recruiters and an improved placement rate from structured candidate and assignment tracking.
ATS, CRM, billing: the priced scope
| Module | Function | Indicative 2026 budget (EUR) |
|---|---|---|
| ATS (candidate tracking) | Pipeline, matching, interviews | 10,000 - 26,000 |
| Client & assignment CRM | Opportunities, accounts, follow-ups | 8,000 - 22,000 |
| Time tracking & staffing | Allocation, day rate, assignment margin | 7,000 - 18,000 |
| Billing & contracts | Quotes, invoices, schedules | 6,000 - 16,000 |
| Candidate/client portal | CV upload, tracking, signatures | 6,000 - 16,000 |
| Candidate data protection | Consent, purge, records | 3,000 - 9,000 |
| Reporting & KPIs | Placement rate, pipeline | 4,000 - 12,000 |
Three-year total cost vs a stack of tools
| Item | Custom | SaaS stack (ATS+CRM+billing) |
|---|---|---|
| Entry cost | EUR 35,000 - 95,000 | EUR 0 - 4,000 |
| Annual recurring | Maintenance EUR 6,000 - 14,400 | EUR 40-120/user/month |
| Timeline | 4 - 7 months | 2 - 6 weeks |
| Unified data | Yes, one base | No, silos + connectors |
| Code ownership | Yes | No |
| 3 years, 15 users (high) | ~ EUR 138,000 | ~ EUR 64,800 |
A SaaS stack stays cheaper to buy; custom is justified when ATS/CRM/billing silos cost consultant time and margin errors.

FAQ
What does consulting/HR firm software cost in 2026? Between EUR 35,000 and 95,000 depending on modules (ATS, CRM, time tracking, billing) and integrations. An ATS + CRM baseline lands around EUR 40,000.

What's the deployment timeline? Between 4 and 7 months, often delivering ATS and CRM first, then billing and the portal.
