Good evening, @AGMrocks. 

Thanks for joining in on this thread. 

The ability to edit the email template for payment receipts still isn't available in your QuickBooks Online account. You can send feedback to our Product Developers so they can consider this in the near future. 

Don't forget to keep up with what's new in the system by using our Blog site. 

I hope this helps answer your question. Have a splendid day and weekend ahead!
