The subtotal function can be called up at any time while creating a receipt. This adds an item to the receipt that shows the total of all products and discounts already added. The subtotal is shown on the customer display and printed on the receipt.
After executing the subtotal function, you can continue registering the order as normal. If the quantity of an item is changed before the subtotal item or a discount is given on an earlier item, the subtotal amount will also change automatically.
