Centrale
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.
Caisse
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.
API Reference
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.Where to go next
