The **Caisse** is the point-of-sale app that runs at the store, on the counter. It rings up sales, takes payment, and keeps the daily cash session — and it carries the full set of in-store counters: returns and exchanges, gift cards, deposits and reservations, rentals, repairs (SAV), quotes, appointments, parked sales, receipts, and store settings. Every screen talks to the same backend as the Centrale, so a price set at head office is the price rung up here, and a sale rung up here is a movement the Centrale can see. ## How the till is organized The app has a short daily-ops rail for the counters a cashier touches all day, plus a back-office hub (**Plus**) that groups the clienteling, service, tools and configuration screens. Browse the catalogue, build the basket, and attach a customer. Settle the sale over one or more tenders and finalize it. Refund against a prior sale and hand back cash or store credit. Open, count and close the register drawer, and read the day-book. ## Online-only for the pilot The till is **online-only**. Each screen selects the backend when the API URL is configured and the cashier is signed in; otherwise it runs an in-process fixture that is a demo aid and drops its writes on reload. There is no offline queue, local-first store, or write buffer — "offline" means fixture mode, not durable offline operation. ## The counters at a glance | Counter | What it does | | ----------------------------------------------------------- | ------------------------------------------------------ | | [Sell](/en/caisse/vente) | Catalogue search, basket maths, customer attach | | [Checkout](/en/caisse/encaissement) | Tender settlement, discounts, finalize the sale | | [Customers](/en/caisse/clients) | Look up and edit the customer attached to a sale | | [Returns & exchanges](/en/caisse/retours-echanges) | Refund against an original charge | | [Gift cards](/en/caisse/cartes-cadeaux) | Issue, redeem and void stored value | | [Deposits & reservations](/en/caisse/acomptes-reservations) | Take a down-payment, hold an item | | [Rentals](/en/caisse/location) | Rent an item against a deposit and close the return | | [Repairs (SAV)](/en/caisse/sav-reparations) | Register a repair drop-off and track it to pickup | | [Quotes](/en/caisse/devis) | Draft a quote and convert it to a sale | | [Appointments](/en/caisse/rendez-vous) | Book a clienteling slot and start a sale from it | | [Parked sales](/en/caisse/ventes-en-attente) | Park a basket and resume it later | | [Receipts](/en/caisse/tickets-recus) | Print, reprint and read the drawer position | | [Daily cash session](/en/caisse/journee-caisse) | Register drawer + the day-book | | [Peripherals](/en/caisse/peripheriques) | Pair the printer, scanner, drawer and terminal | | [Age verification](/en/caisse/verification-age) | Capture proof of age for a restricted sale | | [Store](/en/caisse/magasin) | Read the store, device, seller and session directories | | [AI assistant](/en/caisse/assistant-ia) | Ask the in-store assistant a question | ## Next steps New to the platform?
