At point of sale there is a rewards button that appears up by the customer’s name. This will bring up a picker that shows all the sale items that qualify for rewards and the amounts that would be earned. If you want to exclude some item on the sale from earning rewards, uncheck the box next to the item and it will not earn rewards.
To adjust a customer’s rewards amount, go to the customer record and adjust the balance. This will write out a history row for traceability.
After loading a customer at point of sale, you can select Rewards and the form title will have his or her balance in it.
