Thanks for the response.
I do send receipts that way but it involves extra steps. Is there a way to request the QuickBooks Team add a button to the popup window that I get after I input payment info? Then it would only be a matter of clicking on "e-mail" instead of leaving that screen and doing the above steps.
After I process the payment the following pops up: PRINT CLOSE VOID HELP. It would be so convenient to have E-MAIL added to this selection. Is there a place where I can suggest this?
