How to add subscription fees in FiNIMS?

In FiNIMS, student fees are not managed as monthly subscription billing. Instead, fees are pre-defined at the time of admission and configured for the academic session. All fee structures and due dates are set at the start of the session, though you can update assigned fees anytime since they are calculated in real time.
