This is a mess.  No apparent progress in years.  It seems like if we take the time to order the parts when we created the invoice, it would follow that the invoice to the customer would look like the preview we get in QuickBooks Online.  Just print a few of the invoices and see what your customer sees.  Absolutely a mess and very unprofessional.  What a disservice to every business owner when they may not realize what amess the invoice looks like to their customer.  Then, we ask for thousands of dollars for parts and services and the customer can't reconcile the mess they receive in an invoice.

I have had enough and am switching to another accounting platform.  Quickbooks is not ready for a real business -- maybe works fine for small shop where invoices only have a few lines.
