As an organization, you can choose to "Release" tickets rather than Refund them. When would this happen? Let's say a family comes to your event and lets you know that one member couldn't attend and that they are turning in their ticket.
You can "release" the seat and resell it!
Let's say your a non-profit organization that can accept donations and really appreciate that the consumer turned in their ticket, you can offer to "release to donation." This means that they will get an email confirmation for the donation and you will see the money exchanged to the fund's accounting.
