If you make a mistake, it's pretty simple to fix. Simply hit the 'undo' button in the customer's profile. (If you are running Loyalzoo for Clover, simply perform a refund under the customer's name and it will deduct points automatically).
If you need to rectify a mistake that is not manageable with the undo button. Simply head to dashboard.loyalzoo.com, find the customer using the search box and tap the book icon.
