# FAQ

> Answers to common questions about Solya POS — the apps, the data model, pricing, permissions and the API.

Common questions about how Solya POS works. For definitions, see the
[glossary](/en/getting-started/glossary); for the model, see
[core concepts](/en/getting-started/concepts).

<AccordionGroup>
  <Accordion title="What is the difference between the Centrale and the Caisse?">
    The **Centrale** is the head-office back-office in the browser: it manages the
    catalogue, stock, pricing, orders, transfers, procurement, finance and
    reporting across the whole store network. The **Caisse** is the in-store till
    that rings up sales, takes payment and runs the daily cash session. Both share
    one backend, so data flows between them without re-keying.
  </Accordion>

  <Accordion title="If I set a price in the Centrale, does the till use it?">
    Yes. A product's reference price, any store-specific override
    (`/v1/store-prices`) and active markdowns (`/v1/markdowns`) all resolve to the
    price rung up at the Caisse for that store.
  </Accordion>

  <Accordion title="Why do prices look wrong by a factor of 100?">
    Monetary amounts are expressed **in cents** across the API. €19.90 is `1990`.
    Unless a field states otherwise, prices are also **HT** (excluding tax).
  </Accordion>

  <Accordion title="Why did an action return 403 / why is a screen hidden?">
    Access is scope-based. Your role may not include the required
    `pos.<domain>.<action>` permission. Check your effective scopes with
    `GET /v1/auth/whoami`, and see [roles and permissions](/en/getting-started/roles-and-permissions).
  </Accordion>

  <Accordion title="Can an integration or AI agent do what the apps do?">
    Yes. Everything the Centrale and Caisse do goes through the same REST API,
    which is documented in the [API Reference](/en/developers/overview) and is
    MCP-ready for AI agents. Start with [Authentication](/en/developers/authentication).
  </Accordion>

  <Accordion title="Is Solya POS multi-currency?">
    The pilot is single-currency (EUR). Multi-currency master data is not part of
    the current scope.
  </Accordion>

  <Accordion title="Where do I manage stores, registers and team members?">
    In the Centrale: stores, regions and the device fleet live under
    [Stores, regions & fleet](/en/centrale/magasins-regions-flotte), and users
    under [Team](/en/centrale/equipe).
  </Accordion>

  <Accordion title="Is Solya POS fiscally compliant?">
    The finance surface produces the French fiscal exports (FEC) and NF525-oriented
    fiscal artefacts. See [Finance](/en/centrale/finance) and
    [Reports](/en/centrale/rapports).
