In brief
Preferences gather the personal settings of your session: the interface language and the theme (colors) of the Back-Office. These are display choices for your own comfort; they change neither the till nor the data.
Who / when
For any Back-Office user who wants to display the interface in their language or change the color scheme, at any time.
How to get there
This panel is not in the left menu. Click the avatar (your initial) in the top right of the header: the Preferences panel slides out from the side.
Prerequisites
No specific permission: these preferences are available to any logged-in user.
Screen tour
The Preferences panel slides out as a drawer on the right and offers:
Interface language: a choice between Français, English, العربية (Arabic), and Español. Arabic switches the display to right-to-left.
Back-Office theme: a choice among 4 colors, with an instant preview of the result.
Information: read-only details about the server and the logged-in user.
At the bottom, the Apply (confirm your choices) and Default (revert to the original settings) buttons.
Step-by-step
Change the interface language
Open the panel via the avatar in the top right.
Select the language you want under Interface language.
Click Apply.
Change the Back-Office colors
Open the Preferences panel.
Choose one of the 4 theme colors; the preview updates.
Click Apply.
Revert to the default settings
Click Default to restore the original language and theme.
Messages & edge cases
These preferences are personal: they affect only your display, not that of other users or the till.
The language choice is also available via the 🌐 language icon in the header.
Not to be confused with the POS theme (the till's appearance) set in System → Settings.
Tips
Arabic automatically enables right-to-left reading: handy for an Arabic-speaking team.
