If no tickets have been sold, you can access Event Settings and switch from "Collect RSVPs" to "Sell tickets".
Unfortunately, it's not possible to switch from a ticketed event to RSVP if you've "sold" one ticket. This includes adding attendees from the RSVP tab or free RSVP tickets.
Both types of pages function extremely differently, and our biggest priority is maintaining a clear representation of your information and collected sales!
If you've only added "test" tickets and are in a pinch to change back to RSVP, submit a request and we'll help you work around it!
