What type of event can I sell tickets for?
As long as your event does not involve anything illeagal you can list it. priorbooking.com is designed to sell tickets to events without a seating plan. If your event requires you to sell tickets to specific seats rather than general areas, then priorbooking.com would not be suitable for your requirements. Basically as long as your event does not neded to tie a ticket to a specific seat number then you will be able to sell tickets.
If you have different prices for different areas or sections of the venue, such as standing/sitting or stalls balcony etc you can create this within your event. You can also create tickets wtih different prices for concessions etc.
