Overview - Solya POS Docs

Solya POS is a retail point-of-sale and back-office platform. This section is the starting point: it explains the product at a glance and points you to the right guide for what you need to do.

The two apps

App	Runs where	Who uses it	What it does
Centrale	Head office / browser	Managers, buyers, back-office	Manages the catalogue, stock, pricing, promotions, orders, transfers and reporting across the whole store network.
Caisse	In-store, on the counter	Sales associates, cashiers	Rings up sales, takes payment, handles returns, gift cards, rentals, repairs and the daily cash session.

Both apps are backed by the same API, so data flows between them without re-keying: a product created in the Centrale is sellable at the Caisse, and a Caisse sale is visible to the Centrale.
