Delegate billing works in a similar way to Event Billing, however looks and works slightly differently.
Within a ticketed/ delegate event, each one of the delegates will have their own folio, with their balance against them. Generally speaking, the top function folio of the event should be empty, unless an external charge is to be made to an event holder.
The delegate folio can be entered by selecting the delegate name or + sign next to it. This will show any charges and deposits taken.
Revenue can be added using New Charge and payments can be added using Make Payment, also Options allows for the amendment of charges and Transfer To allows the movement of charges, in the same way as Event Billing. Transfer to > Folio allows the movement of charges between delegates.
An example of a correct folio would be
Menu cost 20.00 (revenue)
Deposit of -20.00 (payment)
= folio balance 0.00.
