## Who does what

Illizeo’s payroll outsourcing runs on **a network of accredited payroll partners**, one per country. The partner produces payroll under local law; Illizeo holds the data, coordinates the cycle and stays your point of contact. It is not the software that calculates: it is a payroll professional in the country concerned.

| Step | Carried by |
| --- | --- |
| Collecting the month’s variable elements | Illizeo — from your modules |
| Checking and freezing the period | Illizeo, with your validation |
| Payroll calculation and payslips | The country’s payroll partner |
| Social declarations | The country’s payroll partner |
| Preparing the payments | The country’s payroll partner |
| Coordination and follow-up | Illizeo |

## Coverage

The network is not a closed list of countries: a partner is identified wherever you employ people, with that country’s declaration format and banking rails — swissdec in Switzerland, DSN in France, Lohnsteuer in Germany, PAYE in the UK, and so on. Tell us about your real footprint before assuming it is not covered.

## Getting started

1. ### Scoping

   A payroll expert reviews your current configuration, your collective agreements and your specifics, country by country. That is where the partner and the timeline are decided.
2. ### Data migration

   Employee records, balances, contracts. The migration is verified against your last payroll export: if the two do not match, we investigate before moving on.
3. ### A month in parallel

   The first cycle runs alongside your current provider. Until both results line up, there is no switchover.
4. ### Switchover

   From the agreed month, the new circuit takes over and the previous provider stops.
5. ### Monthly cycle

   Collection, checking, your validation, production by the partner. The exact calendar is set in your service contract, not here.

## What is not in the software

Illizeo does not compute contributions, does not issue payslips and files no declarations. Those acts belong to the payroll partner, under their professional responsibility and their country’s law. What you find in Illizeo is the input data, the checks, the history and the traceability.

## FAQ

   Who is my point of contact?

Illizeo. You do not have to manage one relationship per country: coordinating with each partner is our job.

   What happens if there is a payroll error?

It is corrected on the next cycle or through a supplementary run, depending on its nature. Any consequences fall under the terms of your service contract and the partner’s: they are read there, not in an article.

   Do we keep control of our data?

Yes. It stays in your Illizeo workspace; the partner receives what the cycle requires, and no more.

   Can we outsource only some countries?

Yes. Nothing requires covering the whole company at once, and most rollouts start with one country.

   What does it cost?

The price depends on the country, the volume and the scope. It is quoted individually.
