The prerequisites for using the fee module are:

creation of a model of charging by the bank (this model will be implemented in the fee module's configuration),

support by the banking system for instructions for charging the client (for example, a non-refusable encashment order).
If clients are allowed to check fees, the appropriate tools must be available within the framework of the user interfaces of the corresponding distribution channels, for example a display of the transaction history, or independent summary of fees.
The prerequisite for processing fee statistics in another system is that such system must support the reading of data in the CSV format.
