A method of building a service subscriber life-cycle data store by an application stored in a non-transitory memory of a computer system and executable by a processor of the computer system. The method comprises periodically reading wireless communication subscriber account logs from a log data store, parsing each of the logs to identify a subscriber associated with that subscriber account log, a time, and an account log type, analyzing the parsed account logs in time sequence order and based on the account log type to identify a plurality of subscriber life-cycle events, for each life-cycle event building a subscriber life-cycle entry comprising a date and time, a subscriber identity, and an identity of a subscriber life-cycle event, where each subscriber life-cycle entry corresponds to a plurality of subscriber account logs, and storing the subscriber life-cycle entry in a subscriber life-cycle data store.
