The verdict in three sentences
Syncing a payroll system and an HRIS costs EUR 6,000 to 25,000 in 2026 depending on API quality and the number of variables (hours, bonuses, absences, benefits). The integration attacks two invisible costs: payroll errors (often 1-3 % of payslips) and the HR hours spent re-keying each month. A standard connector suffices when both tools talk natively; custom becomes necessary as soon as specific business variables must be mapped.
Price and scope in 2026
Cost depends on the number of flows (employee data, payroll variables, absences, expenses) and API availability on both sides.
| Integration scope | Synced flows | Price 2026 (EUR) | Timeline |
|---|---|---|---|
| Basic | Employee data (joiners/leavers) | 6,000 - 10,000 | 2-4 wks |
| Standard | + absences, leave, simple variables | 10,000 - 16,000 | 4-6 wks |
| Advanced | + bonuses, time tracking, expenses | 16,000 - 25,000 | 6-10 wks |
| Native connector | via vendor marketplace | 0 - 4,000 | 1-2 wks |
| Maintenance | rules, rates | 12-18 %/yr | ongoing |
The standard vs custom comparison clarifies the choice based on how specific your payroll is.
| Criterion | Standard connector | Custom |
|---|---|---|
| Cost | EUR 0 - 4,000 | EUR 6,000 - 25,000 |
| Variables covered | generic | all, including business-specific |
| Collective rules | limited | supported |
| Sync direction | often one-way | two-way |
| Timeline | 1-2 weeks | 4-10 weeks |
| Best for | simple payroll | complex, multi-site payroll |
Mini case study
Elodie, HR director at a 120-employee SME in Toronto, re-keys payroll variables between her HRIS and payroll software every month: about 22 hours/month and a 2 % error rate (roughly 2 payslips corrected after the fact). A Standard integration at EUR 13,000 (15 %/yr maintenance) automates absence and variable transfers. Result: HR time drops to 3 hours/month (19 hours saved, ~EUR 7,600/yr loaded) and errors fall below 0.3 %, reducing adjustments and workplace friction. Payback in about 18 months, before counting the reliability gain.
FAQ
Why not just use Excel export/import?
Need a professional website?

Manual export is prone to copy-paste and format errors, and it does not track changes. Integration automates, secures and logs every transfer.
Does the sync handle collective agreements?
A custom connector can map rules specific to your agreement (bonuses, uplifts, thresholds). Native connectors mostly cover generic cases.
How many payroll errors are really avoided?
Companies often see a drop from 1-3 % to under 0.5 % of affected payslips. Each error avoided saves correction time and limits legal risk.
Should the sync run both ways?
It depends: the HRIS is often the source for HR data, payroll for payslips. Two-way sync helps when both tools write shared data.
What is the implementation timeline?
Expect 2 to 4 weeks for a basic scope, 6 to 10 weeks for an advanced project with business variables and expenses.
