Hi, Vlamij.
I'd like to provide some information regarding adding fields for PO numbers in the customer's profile.
You can add a custom field in the invoice for PO numbers since adding PO numbers in the customer's profile isn't an option for us right now.
To customise an invoice, here's how:
- Click the Gear icon at the menu bar and choose Custom Form Styles.
- Go to the Content tab and select the upper portion of the template.
- Scroll down to Display and add Custom field.
- Hit Done.
