Revenue Assurance

Revenue Assurance

23. August 2019 Use Cases 0


Revenue Assurance can be defined as the process of ensuring that all products and services provided by the Telecom Service Provider are billed as per the commercial agreement with customers by ensuring billing – and configuration integrity and accuracy across the relevant systems. This in order to improve profits, revenues and cash flows. Revenue Assurance is practically strongly related to billing assurance.

A telecom organization’s revenue chain is usually a very complex set of inter-related technologies and processes providing a seamless set of services to the end consumer. As the set of products, technologies and business processes grows bigger and more complex, the chance of failure increases. A revenue leakage is typically attributed to when a telco organization is unable to bill correctly for a given service or to receive the correct payment. As an organization grows, the probability of revenue leakage increases.

The best-known estimates of “typical” revenue leakage from Clintworld’s experience with several Telecom operators is worth about 2% of the gross revenue, not including losses due to fraud.

Clintworld offers a managed operations service for full billing assurance in post- and prepaid-business to minimize human errors combined with highly competent technical supervision of machines.

Increasing Importance of Revenue Assurance in Telecom

Although Revenue Assurance has always been present in the telecom market, it has recently been brought at the forefront of the top management. This is due to several factors such as
  • Profit: Increasing cost pressures and decreasing margins. The highly profitable days for most telcos are over. They all need to find alternative means to squeeze higher margins by effectively tracking their revenue
  • Regulatory: New regulatory structure and compliance requirements which force the telecom operators to report their revenue accurately
  • Technology Innovation: Ensuring new technologies and products are performing as per perceived plans. In a hurry to release new technologies in the market, the Revenue Assurance systems may lag behind
  • Mergers and Acquisitions: With increase in the number of telco mergers and acquisitions, organizations are finding it difficult to handle multiple Business Support Systems (BSS) and Operations Support Systems (OSS) including Billing and Rating together
  • Controlling of sales channels: Increasing Importance of indirect sales sets the wholesale and brand partner billing in focus


The most debated part of revenue assurance is where to start checking, i.e. at the network side, the rating side, the billing side, the interconnect side, the CRM side, etc. However, the maximum leakage surely happens during the flow of Call Detail Records (CDRs) or Event Detail Records (EDRs) from the Switch to the respective rating / billing engines. Some of the common problem areas are

Rating & Billing
  • Incorrect rejection logic
  • Duplicated CDRs resulting in double charging
  • Incorrect tariff plans
  • Rating & Billing accuracy errors
  • Incorrect configuration, e.g. rating minutes instead of seconds
  • Incorrect disconnection
  • Lack of synchronicity/consistency between price plan repositories
  • Incorrect zoning, rating to billing, roll-over balances etc.
  • CDRs on switch not sent to mediation
  • CDRs on mediation device not sent downstream
  • CDRs rejected by rating/ billing sytem
  • Wrong duration of the CDRs
  • Incorrect business rules
  • Subscriber provisioning
  • Incorrect routing

Reasons for Billing Assurance

Billing Assurance provides a financial reasoning by uplifting the controlled revenue significantly. In the previous text the revenue leakage worth about 2% of the gross revenue is already mentioned. A consistent implementation of a Quality Assurance Management has a big impact on the revenue as well as on customer satisfaction and the volume of calls and complaints to customer service. The following chart shows the achievable revenue uplift for a company with 588 M Revenue in prepaid-business.
