This thread has been very helpful!  (I'm a new convert from QB Desktop to QBO)

However, I'm stumped on a couple of things.  First, thanks to this thread, I was able to set my customized receipt to the default, but it doesn't quite match what I created!  There's a paragraph I added  that shows in the template, but is completely omitted when I use it for a customer receipt (I've sent test receipts to myself to see what the final outcome would be).

Also, is it possible to delete the "Balance Due" line?  Since I am creating a donation receipt template, there will never be a balance due, and it looks completely out of place on a donation receipt!  I can't find an option to eliminate that line.
