When creating the invoice, you can also add "information lines". This can be useful when you want to add a line without additional information such as amounts, VAT, etc.

How to do it?

1. First, fill in the description and the invoice item. You will automatically get a new line.

2. Then, click on 'add' > information line.

Then, go to 'actions' and delete the excess line where necessary.

Note: The bottom line always remains, but it is not printed.
