Navigate to the "Group discount" tab in your restaurant manager (cloud.gastrofix.com)
("Operator" --> "Customer" --> "Group Discount")
Now click on the "New" Button to create a discount.
If you click on the "edit" button you will see the detailed view:
Discount-Name: Enter the desired name for your discount.
Value: Enter the desired discount value (in percent).
Absolute Amount: If you want to give a fixed amount as a discount, for example 10€, click here on the button to switch to YES. If you leave this field blank, the discount remains in percentages.
Check Discountability: If you want to exclude certain article groups from the discount, set the switch to YES. The discount checks before each payment process whether it is allowed to discount an article. In the item groups, you can specify whether or not they may be discounted.
