Invoicing system and method featuring variable rate depending on amount of service consumed during service interval

摘要

Provided herein are billing methods for cellular service providers to offer customers which take into account the fact that an individual's use varies from one service interval to the next, and automatically adjusts the amount invoiced to the consumer based on the minutes of service actually consumed by a given consumer during a service interval. The amount of money invoiced to the consumer is adjusted for each service interval, with the net effect being the reduction of the total amount of money that the consumer is invoiced over a plurality of service intervals, versus the amount the same consumer would have been otherwise invoiced for identical consumption over the same plurality of service intervals under a single plan featuring a fixed level of threshold minutes and a fixed rate per minute for each minute consumed in excess of the threshold minutes.
