Hello Cj158,
Welcome to the Community page,
Receipt capture can only be used to create expenses and bills, so will be no good for daily sales.
You can only upload 1 receipt/bill at a time using receipts unless you email them in, then they need to be separate images/files and total less than 200MB per email.
It is not possible as the Z report will contain all sales, cash and card ect and they can all be taxed at different rates.
