Can there be a check box added that will automatically add the fee's associated with Pay Direct Online to the invoice if i choose to pass them on. Once checked it should add a disclaimer to the invoice that a 2.2% + 0.25 cent transaction fee applies to all payments processed through this service.
Then when the customer selects view invoice they should be presented with 2 options:
firstly - print and pay (direct debit/cheque) the normal invoice amount
secondly - a pay now button that has the service charges added, which should also clearly state they are MYOB charges. The pay now button would need to automatically generate an updated or a standalone invoice for the transaction fee's
