App language and invoice language

Updated 07.10.2026

AdBooks uses two languages: the app language, which you work in, and the invoice language, which your customers see. In this guide, you set both.

1. Opening the language settings

  1. Click the flag in the top menu.

2. App language and invoice language

  1. The app language is the language of the menus, buttons and messages you see.
  2. The invoice language is the language of the documents your customers see.
  3. In this example, we choose English for the invoices.
  4. This way, you work in your own language, and your customers get invoices in a language they understand.

3. Saving

  1. Click Save.
  2. Done. You can change the language at any time.

Tips

  • You can change the language at any time without affecting your data.
