You don't to have sell 'tickets' to an 'event' to use Quicket. Customise your Quicket page by changing the default wording on your page to better suit your needs.
Start by logging into your Quicket account, and go to Organiser Hub -> My Events then click on the name of your event. From the menu of your event dashboard, choose Settings and then
Definitions.
Your Quicket page by default will show the words 'event', 'events', 'ticket' and 'tickets'. Simply change these by entering your own terms that are more appropriate for your page.
