# Navigation

> How the Centrale back-office and the Caisse till are laid out, and where to find each capability.

Solya POS ships two apps. This page maps each one so you know where to click.

## The Centrale (back-office)

The Centrale runs in the browser at head office. A left sidebar groups the
back-office capabilities; the working area on the right shows lists, detail
panels and forms for whatever you select.

## The Caisse (till)

The Caisse runs in-store on the counter. The centre of the screen is the sale in
progress (the cart); the surrounding controls add items, apply the customer,
handle returns and take payment. The daily cash session frames the shift, from
opening float to close. The Caisse guides cover each screen in detail.

## Finding a specific action

Each Centrale guide follows the same shape:

<Steps>
  <Step title="What it is for">
    A short description of the business area.
  </Step>

  <Step title="Key screens and actions">
    The lists, panels and buttons you will use, matching what you see in the app.
  </Step>

  <Step title="In the API">
    The endpoints behind the screen, so an integration or an AI agent can do the
    same thing — cross-linked to the [API Reference](/en/developers/overview).
  </Step>
</Steps>
