Ah! Thanks for the reminder that the Date of Service is indicated in the invoice body with the actual Invoice date being in the header area. I had customized my invoice template years ago and had removed the Invoice date from that template (I use a different program to send invoices these days, only using QB for general business accounting). Once I modified my customized template to include the Invoice date, I could of course edit it. Thanks for the prompt and helpful reply, MontanaKarl!
