Caisse overview

The Solya POS till: what the point-of-sale app does, how it is organized, and where to find each counter.

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.

Sell

Browse the catalogue, build the basket, and attach a customer.

Take payment

Settle the sale over one or more tenders and finalize it.

Returns & exchanges

Refund against a prior sale and hand back cash or store credit.

Daily cash session

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.
