Can I change who pays the ticket fee?

You choose it per event, on the create page under Price, in Who pays the fee:

• Buyer, shown before paying adds the fee on top at checkout. You keep the full ticket price.
• We do, out of the ticket price keeps the price as printed. The fee comes out of what you receive.

After you create the event, the choice is locked for that event. The event page shows it next to Prices. Changing it later would change what earlier buyers were charged. To switch, use Duplicate to start a fresh copy, or pick the other option on your next event.

Card processing is inside the one fee, so there is nothing separate to split.
