Connector API: Allow for connecting all accounting items to reservations.
Currently most accounting items (aside from those created as part of the initial reservation order) are attached only to the customer, not the reservation. A common part of many revenue management system designs is attaching all charges to the reservations they are associated with, to allow for showing breakdowns of all revenue by things like room types, rate plans, and origin. The Mews dashboard should allow users to associate a charge with a reservation when they create it, so that when all accounting items are queried from the Connector API they can all be easily connected to their corresponding reservation.
MEWS provides a different approach to billing. Customer owns everything, not the reservation.
