If you want the ticket fee to be added on top of the ticket price, this can be done when you create a ticket type.

If you add the ticket fee on top of the price, the ticket buyer will pay the entire ticket fee, and you will be paid what is entered in "Price".

How do I do this?

Tick the field "Should the end customer pay the ticket fee?" when you create the ticket type. You will get a preview of what the price to the customer will be, and what you will be paid.

How does this show up in reports?

In reports, the fee will be 0 on tickets where this is activated.
