The language in which the invoice is drawn up depends on a few settings.
In the General settings > Invoice PDF creation you will find:
- Default invoice language (Nederlands, Frans en Engels).
- Invoice language (Standaard taal of taal van de klant).
If the latter setting is set to Relation language, the invoice is prepared with the template in the language set in the relation file.
If the language for invoices is set to Default language, the invoice is always created in the same language, which is the language set as the default invoice language.
If you want to make an invoice in a language only once you can change the default invoice language for a short time until that invoice is created and then restore the setting.
But if you regularly issue foreign-language invoices, you better choose the Relation language and set the language in your relation files correctly.
Please note: An invoice template is used for just one specific language. If you made adjustments to the Dutch invoice template, then you may also have to make the same changes to the templates in the other languages.
