The verdict in three sentences
In an SMB of 120 employees hiring 30 people a year, onboarding costs about 240 hours of HR and IT time, spread across contracts, IT accounts, equipment and follow-ups. An HRIS at EUR 5 to 10 per employee per month, plus EUR 6,000 to 15,000 of custom automation, removes 75% of the admin time and guarantees a ready workstation on day one. Payback usually lands between 6 and 12 months, before counting the security gained on departures.
The 8 hours of a new hire, step by step
Before buying a tool, measure where the hours go. Here is the typical breakdown seen in a Berlin services SMB, with the automation potential of each step.
| Step | Manual time | After automation | Tool or method |
|---|---|---|---|
| Employee file entry (ID, bank details, tax ID, health insurer) | 1 h 30 | 15 min | Online form linked to the HRIS |
| Contract drafting and signature | 1 h | 10 min | Template + e-signature |
| Payroll and social insurance registration | 30 min | 5 min | Automatic export to payroll |
| Account creation (email, business tools) | 2 h | 15 min | API provisioning (Microsoft 365, Google) |
| Equipment order and setup | 1 h | 20 min | Automatic ticket to the IT provider |
| Onboarding schedule and invitations | 1 h | 10 min | Scheduled onboarding journey |
| Chasing missing documents | 1 h | 0 min | Automatic email and SMS reminders |
| Total per new hire | 8 h | about 2 h | 75% time saved |
IT account creation is the most profitable step to automate: it takes the most time and causes the worst first days when it is forgotten.
Tooling options and their cost in 2026
Three approaches coexist. The right choice depends on your software stack and the number of business tools to connect.
| Option | Entry cost | Recurring cost (120 employees) | Strengths | Limits |
|---|---|---|---|---|
| HRIS only (Personio, Factorial, HiBob) | EUR 0 to 2,000 setup | EUR 7,200 to 14,400 per year | Employee file, e-signature, journeys | Few actions inside business tools |
| HRIS + no-code automation (Make, Zapier) | EUR 2,000 to 5,000 | EUR 7,800 to 16,000 per year | Fast, cheap | Fragile beyond 10 scenarios |
| HRIS + custom automation | EUR 6,000 to 15,000 | EUR 8,500 to 17,500 per year | Full accounts, rights, equipment, offboarding | 6 to 10 week timeline |
| Custom internal HR portal | EUR 30,000 to 60,000 | EUR 4,000 to 8,000 per year | Fully tailored | Oversized for 120 employees |
| Status quo (spreadsheet + email) | EUR 0 | 240 h of HR and IT per year | No project | Errors, omissions, access left open |
For an SMB this size, the third row offers the best balance: the HRIS handles the file, and a custom automation layer handles accounts, rights and equipment.
The often forgotten part: offboarding
The same automations cut access when an employee leaves. Field audits regularly show that one SMB in two keeps accounts active for weeks after a departure. With an automated flow, deactivation triggers on the exit date entered in the HRIS, with equipment return and file transfer.
On GDPR, document the data collected, restrict access to employee files and set retention periods. In Germany, the works council (Betriebsrat) has co-determination rights under section 87 of the Works Constitution Act when a tool can monitor employee behavior or performance: involve it early to avoid a blocked rollout.
Mini case study
Jonas, Head of People at a 120-employee services company in Berlin, already uses an HRIS for payroll. He invests EUR 9,000 in custom automation: entry form, e-signature, Microsoft 365 and business tool account creation, equipment ticket, onboarding journey.

Time saved: 30 hires × 6 hours saved = 180 hours a year, at a loaded cost of EUR 50 an hour, or EUR 9,000. A ready workstation on day one avoids on average one lost day per hire: 30 × EUR 280 = EUR 8,400. Annual gain: EUR 17,400, minus EUR 1,200 of maintenance.
Payback: 9,000 / 16,200, about 6.7 months.
FAQ
Do we need to change HRIS to automate onboarding?
Rarely. Most HRIS products on the market have an API or webhooks that can trigger actions. A 2 to 3 day audit, around EUR 1,500 to 2,500, is enough to check.
How long does the project take?
Plan for 6 to 10 weeks for custom automation, including 2 weeks of testing on real hires. An HRIS alone takes 3 to 4 weeks to configure.
Is no-code enough for a 120-employee SMB?
It is enough up to about ten simple scenarios. Beyond that, silent errors and dependence on a single person cost more than the EUR 6,000 to 15,000 of maintained custom development.
Is an e-signature legally valid for an employment contract in Germany?
For most contracts yes, with an advanced or qualified signature under eIDAS. Fixed-term clauses still require written form under German law, so use a qualified electronic signature at EUR 1 to 4 per envelope.
Do the automations cover departures?
They should. Cutting access on the exit date is the most cost-effective security measure, for an extra EUR 1,500 to 3,000 in the project.
