I'm also aggravated with the inability of Quickbooks to customize forms. We were using Quickbooks Online Plus, on July 2023, I was able to customize our Purchase Order. I created a template that Instead of Activity It showed - Parts, Price instead of Rate and Total instead of Amount. Also there was no Approved By or Date lines. On November 3023 I received a call requesting to edit the Purchased Order, which I tryed and I was unable to do it, even with the help. I was told that I shoud  concider upgrade to Advance, however, reading the discussions, seams like it is not possible either. I need someone in Quickbooks to resolve this issue, I can't send the Quickbooks forms as it is.
