Issuance of invoices for cash payment is performed in the following way:
Click on one of the main categories which contains a sub-category with ordered drink. For instance, if your guests ordered two teas, first you click on the main category “Drinks” where sub-categories are opened in the first vertical column. Sub-category “Hot beverages” is the sub-category where you will find your desired item “Tea”.
Clicking on this sub-category will show you in the second vertical column all items, including the desired item “Tea”. Each click on the desired item increases the quantity for 1. Ordered items can be seen in the third vertical column. In case you entered a more quantity then ordered, each click on an item in the third column decreases the quantity for 1. This makes even more easier to do issuance of invoices for cash payment.
