Additional Tax Fields On The Invoice

Hello!

Our store (multi vendor) is located in Poland and we need to by compliant with the polish law when it comes to the invoices.

I couldn't find any documentation on the custom fields, which we've added to the vendor admins accounts, and how to show them on the invoice. It's always a different field code in the editor, and the editor is SOOOO 90s, that it is really frustrating.

Another topic is that we also wanted to switch to monthly invoices as soon as possible. So a restaurant buys whatever the need, weekly, from many suppliers. But once per month they get a summary invoice per supplier. Perhaps that's something that should be in another topic?

I would appreciate any help on that!
