Give your customers the option to pay for their tickets in multiple partial payments. You can set up scheduled payments from within your event editor by switching /edit to /ticket_types. The /ticket_types URL will give you the option to first select a ticket type, and then add a payment amount and schedule its payment. Additional payments can be scheduled for specific dates, or the day of the event.
When using scheduled payments the Price of the ticket type will be charged at the time of checkout. Customers purchasing tickets with scheduled payments will also be notified about the future payments before purchasing.
