Custom fields to invoices

Hi guys
I run a small garage business and would like to add 3 custom fields to my invoices, I added the 3 I want but I can only get 1 to show and it’s at the bottom of the page, is it possible to have more than 1 custom field and can I position them elsewhere on the page

Many thanks


Have you read this Guide

The fields appear only when something is in them (assuming you’ve set them up to show on printed documents). You can control their order using the Position field. But to move them elsewhere requires a custom theme. Depending on where you want to put them, the programming could be relatively sophisticated. See this release note:
