One point can easily have an employee who'd rather see the interface in a different language than the one the Owner set it up in — in a border region or a tourist town that's not the exception, it's the norm. In RentOS the interface language isn't hard-wired to the whole business: it's a setting anyone can override just for themselves.

15 Languages — Not Just Two for Show
The interface is translated into fifteen languages — Russian, English, Romanian, Ukrainian, Polish, Turkish, Armenian, Georgian, Azerbaijani, Kazakh, Kyrgyz, Tajik, Uzbek, Italian, Belarusian. That set isn't random — it reflects the regions where RentOS rental points actually operate, not some abstract for the future list.
The Business's Language and a Person's Language Are Different Things
The Owner sets a default language for the whole tenant at sign-up. But any user — the Owner themselves or an employee on their own device — can switch the language just for themselves, without touching anyone else's setting. An employee sees the dashboard in their language, the Owner in theirs, and the two don't conflict.
It Translates the Interface, Not Your Data
Zone names, asset names, rate names, any comments — that's your own data, and it stays exactly as you entered it, no matter what language a given user is viewing it in. Only the interface elements themselves get translated — buttons, labels, screen text — not what you typed into the system.
Why This Isn't a Small Thing
For a business on the border of language zones, or with seasonal staff from another region, the choice is usually either train everyone to work in an interface in a foreign language, or don't use a proper accounting system at all. RentOS removes that dilemma: the language adapts to the person, not the person to the program's language.
