It is possible to add extra fields to an invoice based on elements from the Peppol BIS Billing format. These follow a fixed structure and must be copied exactly. Below you will find the complete list.

In parentheses, the text type is indicated. You can choos the description and it will be displayed on the invoice if you check the 'use description' box. If you do not do this, the text from the name field will be automatically shown.
