If participants decide they need to cancel or delete an item they have signed up and paid for, they will first need to contact you as the sign up administrator. Once they do, you can log into your SignUpGenius account and click the sign up from your account Sign Ups page.
You can fully or partially refund a buyer by accessing the Admin's Toolbar at the top of your sign up and clicking the Add/Edit/Delete People button. You will see the refund icon next to each user who has signed up and paid.
