To be able to give your customers a discount, you must create predefined discounts in the restaurant manager. Go to "Setup" --> "Financial" and select the "Discounts" tab.
Choose "Add New" to create a new discount.
Name: Assign a discount name - in some cases it makes sense to specify the value of the discount in order to know how high the selected discount is during the payment process.
Discount Value: Enter the value of the discount as a number without the unit.
Absolute Amount: Activate this field if you want the discount to be deducted as a euro amount instead of a percentage.
Check Discountability: Activate this field if only certain, previously defined, articles may be discounted (e. g. cocktails during happy hour).
Save your settings and load the master data from the cloud after creating all desired discounts with your cash register.
