The verdict in three sentences
For 100 to 200 hires a year, self-hosted n8n workflows at EUR 6,000 to 12,000 offer the best balance of cost, control and GDPR compliance. Make at EUR 30 to 300 per month suits a fast start if HR data may flow through a third-party service. A custom application around EUR 25,000 makes sense when onboarding becomes a full employee journey, with a portal, e-signatures and tracking of the first 90 days.
What manual onboarding really costs
The HR director of a 900-employee group in Berlin handles about 150 hires a year. Each one triggers email threads with 6 departments: HR, payroll, IT (accounts and licences), facilities (badge, desk), the manager and training. The result: accounts created on day one at 11 am, a laptop delivered in week two and mandatory training forgotten.
| Onboarding step | Manual time per hire | After automation | Department |
|---|---|---|---|
| File and contract entry | 1 h 15 | 20 min | HR |
| Account creation (AD, email, HRIS) | 1 h 30 | 10 min | IT |
| Equipment and badge order | 1 h | 15 min | Facilities |
| Mandatory training enrolment | 45 min | 5 min | Training |
| Manager reminders and day-30 checklist | 1 h | 15 min | Manager and HR |
| Payroll setup | 45 min | 30 min | Payroll |
| Total | 6 h 15 | 1 h 35 | 6 departments |
2026 ballpark: about 5 hours saved per hire, or 750 hours a year for 150 hires, close to half an administrative position.
n8n, Make or custom: the comparison
| Criterion | Self-hosted n8n | Make (SaaS) | Custom application |
|---|---|---|---|
| Setup | EUR 6,000 to 12,000 | EUR 3,000 to 8,000 configuration | About EUR 25,000 |
| Recurring cost | EUR 40 to 120 per month (EU server) | EUR 30 to 300 per month depending on operations | EUR 200 to 500 per month |
| Data hosting | Your servers or a German cloud | Vendor infrastructure | Your infrastructure |
| HRIS, AD, Microsoft 365 connectors | Native or via API | Native, very many | Built as needed |
| New hire portal | No, emails and notifications | No | Yes, personalised journey |
| Deployment time | 6 weeks | 3 to 4 weeks | 10 to 12 weeks |
| Internal maintenance | Technical skills helpful | Low | Provider or IT team |
The most common choice for a group this size: n8n hosted in Germany, triggered by the contract signature in the HRIS, which creates Microsoft 365 and Active Directory accounts, opens equipment tickets, enrols the employee in training and sends the manager a dated checklist at D-7, D+1, D+30 and D+90. Every step is logged, which meets GDPR requirements on traceability of access to personal data. In Germany, involve the works council early, since tools that process employee data usually require its agreement.
Mini case study
Anna, HR director of a 900-employee group in Berlin, works out the current cost: 150 hires times 6 h 15, or 940 hours a year across 6 departments, at an average loaded hourly cost of EUR 45, so EUR 42,300 per year. After automation with n8n, 1 h 35 per hire remains, or 240 hours and EUR 10,800.
Annual saving: EUR 31,500. The project costs EUR 10,000 of setup plus EUR 80 per month of hosting. It pays back in under 4 months, not counting the effect on the probation period: a new hire who is productive from day one lowers the risk of early departure, often estimated at several months of salary.

FAQ
How much does onboarding automation with n8n cost?
Setup ranges from EUR 6,000 to 12,000 for a group of 500 to 1,000 employees, plus EUR 40 to 120 per month of EU hosting. The price mainly depends on the number of systems to connect.
Is Make GDPR compliant for HR data?
Make offers EU hosting and a data processing agreement. For sensitive data such as social security numbers, many IT teams still prefer self-hosted n8n, which keeps 100% of flows on their own infrastructure.
How quickly is the system live?
Plan 6 weeks for n8n: 1 week of mapping, 3 weeks of building, 2 weeks of testing on 5 to 10 real hires. Make can be ready in 3 to 4 weeks.
Do we need to change our HRIS?
No. Workflows plug into common HRIS platforms via API or scheduled export. Only an HRIS with no API at all requires a daily file export.
Can offboarding be automated too?
Yes, the same foundation handles departures: account deactivation, equipment return, final pay. The extension usually costs an extra EUR 2,000 to 4,000.
