If you are looking to have the registrant cover your credit card processing fees with registration, follow these instructions:
1. Go to Registrations tab at the top of the screen
2. Create a form or edit an existing form
3. Go to the Fees tab on the left
4. Where it says 'Pass Transaction Fees to Participant' turn that to Yes
With this turned on, if your fees are $200 for example, your organization will take home $200 and the registrant will pay the $200 plus whatever transaction fees are incurred.
