Revenue assurance is the application of a process or software solution that enables a communications service provider (CSP) to accurately capture revenue for all services rendered. Instead of correcting errors after they occur, or not detecting and correcting them at all, revenue assurance enables the CSP to examine and plug dozens of actual or potential leakage points throughout the network and customer-facing systems, and to correct data before it reaches the billing system. The distinctions between revenue assurance and other disciplines are often blurred. Revenue assurance sometimes extends into areas such as network assurance, service assurance, business assurance, risk management and fraud management.
