If a customer comes to the checkout to pay for their online store order, the customer's name should be entered into the company or person field.
Then click on Orders/Invoices.
Note! The order must be paid for in full at the checkout and cannot be partially paid. Billing/Account Sales/Credit payment methods should not be used for order payments.
Again, the cash register sales report will show "Order Fee VAT 0%" for this transaction, and the sales will be detailed in the online store sales report.
