Billdu can display invoices and other documents in several languages:

You can change the language of every document at any time. While editing an invoice select Details (app) or More details (website) and select a language from a drop-down box.  

WEBSITE
In the upper right corner of the webpage click on your business name. Click on the arrow, select Language and choose English, German, French, Spanish, Italian, Slovak or Czech.
​

MOBILE APP
Select Settings and choose Language. You can choose from English, German, French, Spanish, Hungarian, Italian, Dutch, Polish, Slovak, Czech and Arabic. 

​

Note: Some texts such as e-mails, reminders, expense categories, etc. are pre-set at Billdu at the time of your registration and are based on your location, browser settings or mobile device settings. These pre-defined texts can be changed later in the Settings and are not affected by the app language.
