How to I set a Fixed Booking/Service Fee for each ticket sold?

This is the quickest and simplest method if you just want to add a fixed fee per ticket sold calculated at the checkout confirmation and applied to the order totals.

#1 Go to Admin>Payment>Advanced>Order Totals

DELETE all your Order Total modules installed and we need to RE-INSTALL them including the Booking Fee (per ticket) module. (this is so that we get a correct order of modules that calculate the costs)

Set the Booking Fee at a Flat Rate or Percentage as shown.

SAVE this module

#2 Set the language file

We may need to edit the language file...
