How do I know the total collection for my event?

As and  when a ticket sale happens for an event, a mail is sent to the Buyer and a  copy of that transaction mail is sent to the event Organiser and that mail  has  the ticket detail and option to  print the ticket.  The Gross revenue collection is shown on the event dashboard under Overview  page.  You can also download the buyer  list and add the amount column to get to the value of total collection.
