There are several ways to close ticket sales:
Scheduled time:
When creating your event, you can schedule the time you want to close the online ticket sale, within the “tab” “Date and Time":
*This date can be modified at any time, in case you want to advance or postpone said closing.
General manual closure:
If you want to close the sale before the scheduled time, you can do so by editing the event, accessing the section “Basic info", and checking the option "Visible on the sales website" as "closed”.
Manual closure by entry type:
If there is a chance that a specific type of ticket is sold out at the box office, you can close the online sale manually. Access the event and scroll down to the “New ticket”, where you will find the list of the different types of tickets offered for that event. There you can select the option “status” and change it to “Sale closed”.
