Fee in the price, or on top? What the buyer sees

You set a starting price, and a switch in the price editor decides where the fee sits.

All-in, the default: the buyer sees one number and pays it. The fee is inside it, and no second line appears at checkout. You keep the price less the fee, and the editor shows that figure as "You keep".

Buyer pays the booking fee: the buyer sees your price, and the fee is added at checkout as its own line. You keep the price.

Either way the editor shows what you keep next to what the buyer pays, so move the price until the keep is right. The fee is charged once per order, not per ticket; see what you keep.
