KillBill is a module in the TMC Core system that primarily serves licensed IATA agencies.
Through this module, it is possible to track billing for past periods and upload new ones in a fast and secure manner.
Since IATA calculations are different from market to market, in the current version of KillBill it is possible to display IATA billings for Croatian, Slovenian and German markets.
All accounts can be downloaded later in different formats and you can also go back to the specified period and billing.
