The verdict in three sentences
Linking your HRIS and payroll to a self-service HR portal costs in 2026 between 15,000 and 45,000 EUR, depending on the synced flows and the security level. The realistic timeline runs 6 to 12 weeks, with maintenance of 400 to 1,000 EUR/month. The gain: HR admin tasks drop by roughly 50% and employees manage leave, documents and details on their own.
Sensitive data means serious data protection
An HR portal handles sensitive personal data: salaries, sick leave, bank details. In 2026 the integration must include encryption, access logging, data minimisation and fine-grained permissions. This is not optional: it is what separates a 15,000 EUR project from a 45,000 EUR one.
| Synced flow | Direction | Data sensitivity |
|---|---|---|
| Employee record | HRIS to portal | High |
| Leave and absence | Bidirectional | Medium |
| Payslips | Payroll to portal | Very high |
| Expense claims | Portal to HRIS | Medium |
| Details / bank info | Bidirectional | Very high |
| HR documents | HRIS to portal | High |
2026 pricing grid by tier
| Tier | Scope | Cost | Timeline |
|---|---|---|---|
| Essential | Leave + documents | 15,000-22,000 EUR | 6-8 wks |
| Standard | + payslips + details | 22,000-33,000 EUR | 8-10 wks |
| Full | + expenses + approval workflows | 33,000-45,000 EUR | 10-12 wks |
| Monthly maintenance | Security, changes, support | 400-1,000 EUR/month | Ongoing |
Add the possible cost of the HRIS connector on the vendor side (some bill the API 150 to 500 EUR/month) and a data-protection compliance audit if you do not have one.
Mini case study
Nathalie, HR director of a 280-employee industrial mid-cap in Toronto, handled leave requests and payslip distribution by hand: about 60 hours/month for her team of 2 administrators. She invests 28,000 EUR in a Standard HRIS + payroll integration, plus 650 EUR/month maintenance.
Payoff: self-service absorbs leave, payslips and details; the admin load falls to ~30 hours/month, saving 30 hours. At a loaded cost of 30 EUR/hour, that is 900 EUR/month, or 10,800 EUR/year. The integration pays back in about 26 months, before qualitative gains (fewer errors, better employee experience, stronger compliance).
