Currently, Evey Events & Tickets (Evey) does not offer a feature to limit the number of tickets a single customer can purchase.
While you can set a maximum number of attendees or limit the total number of tickets available, this does not prevent a customer from purchasing multiple tickets, as long as the inventory is still available.
We’re always working to improve the app and add features that help merchants manage their events more efficiently. If this feature becomes available in the future, we’ll be sure to let you know!
