How to change the currency and language of your account

5 min readUpdated October 28, 2026

Fix the currency or the language shown in the app or in the back-office.

If your sales appear in the wrong currency (for example dollars instead of euros) or the screen is not in your language, you can fix both settings.

Note: the app and the back-office each have their own settings. Changing the language or currency in the back-office changes nothing on your registers, and the other way round. Pick the app or the back-office (on a computer) below.

Change the currency from the app

The screens are those of the Tunder app on a phone or tablet.

  1. Open Settings

    Tap the menu icon ☰ at the top left, then Settings. Stay on the General tab.

  2. Tap “Currency”

    The “Currency” row is below the shop settings and shows the current currency. A “Pick a currency” list opens, with a search bar.

    • Search: type the code (EUR, CHF, USD…) or the name of the currency.
    • Tunder lets you sell in more than 150 currencies.
  3. Choose the currency

    Tap the currency you want: it is saved right away.

    • During a sales session: the currency can only be changed before the first sale of the session. Otherwise Tunder shows “Currency change blocked”: close the session first, then change the currency.

Change the language from the app

  1. Open Settings

    Tap the menu icon ☰, then Settings, General tab.

  2. Tap “Language”

    The “Language” row shows the current language. A list of languages opens.

  3. Choose the language

    Tap your language: the app is shown in that language.

Frequently asked questions

My sales appear in the wrong currency. What can I do?
In the app: menu ☰, Settings, General tab, “Currency” row, then pick the right currency. In the back-office (admin.tunder.co): Settings, General tab, “Currency” row. The two settings are independent.
Why do my sales show 0 after changing the currency?
You probably picked a different currency from the one your sales were made in. Set the currency used for the sales again (for example the euro if you sold in euros): Settings, General tab, “Currency” row.
Why does Tunder show “Currency change blocked”?
In the app, the currency can only be changed before the first sale of the current session. Close the session first, then change the currency.
If I change the language in the back-office, does the register change too?
No. The back-office language and currency are kept in your browser. On the register, they are set in the app: menu ☰, Settings, General tab.
Why is the back-office in a different language from mine?
Until you pick one, it follows your browser's language, and English if that language is not available in Tunder. Pick yours in Settings, General tab, “Language” row.
How many languages and currencies does Tunder offer?
27 languages and more than 150 currencies. Both lists have a search bar to help you find yours.
