Yes, you can. When setting up your event for ticketing in the Eventfinda Promoter Portal, simply change the "Pass Credit Card Fee To Customer" flag to Yes and the credit card fees will be passed along with ticket purchases.

Because Eventfinda shows customers all fees and charges the instant they select tickets, there are no surprises or "drip pricing" issues for your customers and they will clearly see the 2.5% credit card cost in their ticket order.
