Frequently asked questions about Crésus migration
How long does the migration take?
On average 30 to 60 days depending on which modules you use and how many financial years you carry over.
Do we keep Swissdec-compliant payroll?
Yes. Crésus Salaires is Swissdec-certified and Numezis payroll is too, so declarations continue uninterrupted.
Will my operations be interrupted?
No, you keep working in Crésus throughout the transition. We cut over only once the consistency tests pass.

Our Swiss team supports you in French and German at every step. First call is free.
