The Billing module is responsible to identify, rate and invoice all billable entities. Both services and physical goods are considered billable (see Products for more details on services and physical goods)
Billing is performed through Normal Billing runs, a billing mechanism which is used in cases where customers start using the services that were subscribed to or delivered to them, and by the end of their billing frequency period they are charged for those services. Normal billing run can manage both pre – billed and post-billed services. Pre Bill Services are services which should be billed in advance, before they have been used, either period based or anniversary based. Post Bill Services are services which should be billed after they have been used.
Normal billing run follows specific billing rules which are defined in normal billing run definitions, considering also billing related rules and restrictions defined in billing term schemes and billing term definitions. The core functionality of the mechanism relies on identifying billable or creditable information which is then rated, resulting to rated billing item records, which are later on billed in the form of financial transactions and grouped within bills.
