The verdict in three sentences
In a mid-size company hiring more than 100 people a year, manual onboarding costs about 9 hours of work per new starter, spread across HR, IT, facilities, payroll, management and safety. A custom workflow (15,000 to 35,000 EUR excl. VAT) plugged into your existing tools is often more profitable than a full HRIS at 8 EUR per employee per month, unless you were planning to replace your HRIS anyway. The main gain comes from automated account creation and reminders, not from a pretty welcome portal.
Where the 9 hours per hire go
For every new starter, six departments are involved in a Berlin industrial or services company. A typical diagnosis on 20 recent hires shows:
| Department | Tasks | Manual time | Time after automation |
|---|---|---|---|
| HR | Contract, social security registration, file, benefits, document chasing | 3 h 30 | 1 h 15 |
| IT | AD/Microsoft 365 accounts, licenses, laptop | 2 h 30 | 0 h 30 |
| Facilities | Badge, parking, desk, safety equipment | 1 h 15 | 0 h 30 |
| Payroll | Employee record, bank details, tax class | 1 h 00 | 0 h 15 |
| Manager | First-week plan, buddy | 1 h 30 | 0 h 45 |
| Health & safety | Safety induction, mandatory training | 1 h 00 | 0 h 30 |
| Total | 10 h 45 | 3 h 45 (≈ 7 to 9 h saved) |
Over 140 hires a year, that is about 1,260 hours recovered, roughly 0.8 FTE. The indirect benefit matters as much: a new starter who has a laptop, badge and access on day one becomes productive a week earlier.
Custom workflow or HRIS: the 2026 comparison
| Criterion | HRIS with onboarding module | Custom workflow |
|---|---|---|
| Upfront cost | 5,000 to 20,000 EUR deployment | 15,000 to 35,000 EUR |
| Recurring cost (650 employees) | 8 EUR/employee/month, ≈ 62,400 EUR/year | 3,000 to 6,000 EUR/year (hosting + maintenance) |
| Timeline | 4 to 9 months (full HRIS project) | 3 months |
| Integration with existing tools (payroll, AD, badges) | Standard connectors, sometimes paid | On your tools, including badges and ERP |
| Fit with specific processes | Limited configuration | Full |
| When it makes sense | Current HRIS needs replacing | Payroll and HRIS work well |
The right call depends on your current HRIS. If payroll and time tracking work, paying 62,400 EUR a year to get an onboarding module is disproportionate. If your HRIS is end-of-life, folding onboarding into the replacement project is logical. In Germany, remember to involve the works council (Betriebsrat) early: any tool that processes employee data requires its consultation.
What the workflow actually does
| Trigger | Automated action | Connected tool |
|---|---|---|
| Offer signed | File created, employee form sent | E-signature, HR database |
| Documents received | Completeness check, reminder at D+3 | Email, SMS |
| D−10 | Accounts, licenses, laptop order | Microsoft 365, Active Directory, ITSM |
| D−5 | Badge, parking, assigned desk | Access control, facilities tool |
| D−3 | First-week plan sent to manager and buddy | Calendar, Teams |
| D+1 to D+90 | Mandatory training, check-ins, first-impressions survey | LMS, form |
The project runs over 3 months: 3 weeks mapping with the 6 departments, 6 weeks of development and connections, 3 weeks of pilot on about ten real hires.

Sophie, HR director of an industrial company in Berlin (650 employees, 140 hires a year), picks a custom workflow at 28,000 EUR with 400 EUR a month of maintenance. Gain: 1,260 hours a year at an average loaded cost of 48 EUR, so 60,480 EUR a year or 5,040 EUR a month. Net monthly gain: 5,040 − 400 = 4,640 EUR. Payback: 28,000 ÷ 4,640 ≈ 6 months. By comparison, an HRIS at 8 EUR per employee would cost 62,400 EUR a year in subscription alone.
FAQ
Does the workflow work with outsourced payroll?
Yes, it sends a file or API call to the payroll provider with the employee data. Allow 2 to 4 days of development per connector, about 1,500 to 3,000 EUR.
What happens to candidates' personal data?
Data is hosted in Germany or the EU, with role-based access and GDPR-compliant retention periods. A processing record and a simple impact assessment are part of the delivery.
Can it handle offboarding too?
Yes, and it is often the second phase: revoking access within 24 h removes a real security risk. The extension usually costs 5,000 to 9,000 EUR.
Do managers need to change their habits?
Barely: they receive a task in Teams or by email with a checklist. Manager task completion usually rises from 60% to over 90%.
How soon can we measure the gain?
From the pilot: on 10 hires, we measure time spent per department and the share of access ready on day one, which should exceed 95%.
