# Solya POS

> The Centrale back-office, the Caisse point-of-sale, and the REST API that connects them.

Solya POS is the retail operations platform behind the counter and behind the
scenes. It ships as three surfaces that share one backend and one data model:

<CardGroup cols={2}>
  <Card title="Centrale" icon="building" href="/en/centrale/overview">
    The head-office back-office: catalogue, stock and inventory across the whole
    store network, transfers, orders (OMS), procurement, finance, pricing,
    promotions, loyalty, customers, quotes, team, and reporting.
  </Card>

  <Card title="Caisse" icon="cash-register" href="/en/caisse/overview">
    The point-of-sale till: sales, checkout and payment, returns and exchanges,
    gift cards, deposits and reservations, rentals, repairs (SAV), quotes,
    appointments, parked sales, receipts, and the daily cash session.
  </Card>

  <Card title="API Reference" icon="code" href="/en/developers/overview">
    A REST API that exposes every POS capability — generated from the live
    backend OpenAPI spec, and MCP-ready for AI agents.

## How the pieces fit together

The **Caisse** runs at the store, on the counter. It records sales, takes
payment, and keeps a daily cash session. The **Centrale** is where the network
is managed: what is sold, at what price, in which store, and how stock moves
between them. Both talk to the same backend, so a price set in the Centrale is
the price rung up at the Caisse, and a sale at the Caisse is a movement the
Centrale can see.

The **API** is that same backend, documented. Anything the two apps can do,
an integration — or an AI agent — can do through the API.
