I'd like to add a QR code and additional text to my invoice forms so customers can read a description and scan a QR code image that is linked to a Google Reviews page. Is there a way to get this done inside the forms designer?
It's been a long time since I've created an Invoice, but you MIGHT be able to insert a graphic (i.e., the QR code) in the Message section of the invoice.
But Q itself can't create that QR code, so you'd need an external source for it.
