For each event, you can make multiple entry tickets available at the same time. You can make use of this option in a number of ways:
Create an Early Bird (pre-sale) ticket when ticket sales have just started, followed by a Regular ticket.
Sell separate tickets for dinners or exclusive workshops, or day tickets and evening tickets.
Offer both free and paid tickets for your event (eg. free tickets for VIPS or partners and paid Regular tickets).
You can also set the number of extra guests per ticket.
You can create as many entry tickets as you want from the Ticket Module. You can determine specific settings for each ticket. Read more about the general settings and the settings for paid tickets.
