# Subsidiaries

A **subsidiary** is a **separate entity** within the Charlie Gestion platform.\
Each subsidiary has its own data (sites, zones, materials, teams, alerts, etc.) and its own users.

Users can therefore:

* manage several agencies, legal entities or regional departments separately,
* finely control who has access to which subsidiary,
* keep information siloed to avoid any confusion or mixing of data.

## What are subsidiaries for?

Managing by subsidiary lets you:

* **Structure a multi-site organization**: a company can manage several independent agencies or job sites.
* **Secure data**: each user only accesses the subsidiaries they are authorized for.
* **Simplify oversight**: the administrator can easily switch from one subsidiary to another to view information.
* **Assign the right roles**: a user can be an administrator on one subsidiary, but a simple reader on another.

<i class="fa-right">:right:</i> **Example**: A construction company can create one subsidiary per regional agency (*North*, *Île-de-France*, *South-East*) to separately manage its job sites, materials and teams.

## Subsidiary configuration

The primary administrator can view the configuration of each of their subsidiaries in the subsidiaries table:

* **Maximum number of users**: number of users that can be attached to the subsidiary.
* **Maximum number of QR codes**: number of QR codes that can be associated with the subsidiary's elements.
