The great thing about Sticky Tickets is you only pay for what you use. There is a small booking fee per ticket for tickets sold to paid events, and that's it- there are no other costs.
You choose whether you add the booking fee to the ticket price for the customer to pay, or simply deduct it from your ticket sales. The booking fee is calculated on the price of your tickets. If you hold an event which is free to attend, then no booking fees are incurred when people register.
Please see our pricing schedule at: http://www.stickytickets.com.au/sell-tickets (scroll to bottom of page to use our booking fee calculator)
If you have any further questions about costs or anything else, please don't hesitate to contact us and we'd be more than happy to help.
