The verdict in three sentences
Custom staffing software is budgeted between EUR 18,000 and 48,000 in 2026 in Amsterdam, versus EUR 750 to 1,800/month for an off-the-shelf HR ERP. Automated candidate-assignment matching cuts placement time by about -35%, a direct revenue lever. Deliverable in 10 to 18 weeks, it amortizes against an ERP subscription from year 2 or 3.
Off-the-shelf HR ERP or custom software
| Criterion | Off-the-shelf HR ERP | Local custom |
|---|---|---|
| Cost | EUR 750–1,800/month | EUR 18,000–48,000 once |
| Fit to local law (contracts, filings) | low | total |
| Candidate-assignment matching | generic | tailored |
| Talent-pool management | standard | advanced |
| Assignment schedules | rigid | flexible |
| Support & language | remote | local |
| Code ownership | no | yes |
The off-the-shelf ERP bills monthly and fits local contracts and filings poorly. Over 3 years, a subscription at EUR 1,200/month is EUR 43,200, often more than a full custom build.
Modules and quantified gains

Ms Okemba, head of a staffing agency in Amsterdam, places 200 assignments/month and loses time matching candidates to needs. Custom software is quoted at EUR 33,000, plus EUR 5,000/year maintenance. The -35% placement-time cut frees the equivalent of EUR 7,200/year of workload and lets her handle more assignments at constant headcount. Compared with an off-the-shelf ERP at EUR 1,200/month (EUR 14,400/year), custom pays back in about 3 years then is markedly more profitable.
