Users on the Expert plan are charged a 1% success fee for every sold itinerary. This fee is charged on the 1st of the month for all itineraries starting in that month. For example, confirmed itineraries with start dates 5 March, 17 March and 20 March will be invoiced on 1 March. However, if the itinerary start date is 28 March, and the itinerary was confirmed on 5 March, you will be invoiced the following month, i.e. 1 April.
