Evey Events & Tickets supports reserved seating, where each seat is typically limited to one customer. If customers are able to purchase multiple tickets for the same seat, it's likely due to seat capacity settings.
How to Set Seat Capacity to One Per Seat
Once you're on the Evey Events & Tickets app, go to "Settings".
Once there, go to "Locations and seating".
Now click on the events' "Seating plans".
Then scroll down to "Seats" and make sure that seat capacity is set to 1 per seat label.
If they are not set to 1, you can click on "Edit" and change to capacity to 1.
Finally, don't forget to hit "Save".
If, despite implementing this adjustment, you encounter any further difficulties with customers being able to purchase multiple seats, please feel free to reach out to us.
