I added the field to the custom invoice by going into the template then clicking additional customization then making sure that the Bill To was checked for screen and print.  I am new to quick books and this is the first time I have ever used it, had it for a month.  Coming off of paper only---FYI.  My customer data base is empty and I will be building it hopefully soon.  While creating the invoice, I put the customer name into the bill too.
