The significance of revenue assurance in the telecom industry

Billing systems have become increasingly complex. Bundled and tiered offerings, inter-related technologies, and complex processes increase the expectations from the billing system.* Reeling under such pressure to keep up, security barriers in the system might wear thin and vulnerability to revenue loss might increase. According to a study, global telecom operators have lost $30 billion in uncollected funds and $135 billion in revenue leakage.


What is revenue assurance in telecom?

Revenue assurance implies that a telecom company bills its products and services as per the commercial agreement with the client. It ensures the integrity and accuracy of all systems involved in invoicing and billing.

The importance of revenue assurance

Revenue leakage rises when a telecom company cannot bill a client correctly for its services. With millions of customers and frauds to deal with, it is an uphill task to maintain the integrity of the billing system. Here are some of the reasons revenue assurance is at the forefront of every telecom company’s priorities:

  • Profits:
  • With cut-throat competition and minimal revenue from messaging and calls, telecom operators have to find alternate avenues for income. One of these is monitoring and plugging in the revenue leakage in their existing processes and systems.

  • Regulatory compliances:
  • Telecom operators need to report their annual revenue accurately. Revenue assurance helps them do so.

  • Technology innovation:
  • Companies constantly innovate and introduce new services for their customers. This involves newer backend systems and technologies. New technologies ease and modify operations or increase profits. At such junctures, revenue assurance mustn’t be neglected.

  • Mergers and acquisitions:
  • When telecom operators merge or one acquires the other, it is important to integrate the multiple Business Support Systems (BSS) and Operations Support Systems (OSS).

  • B2B sales channels:
  • Indirect sales through wholesale and brand partners also bring the billing systems and their integrity into focus.

Challenges in revenue assurance

It is a challenge to know where to begin investigating for flaws. Maximum revenue is leaked during call detail records (CDRs) and event detail records (EDRs) between the switch and the billing engines. The problems include:

  • Incorrect logic for rejection
  • Double charging due to duplicate CDRs
  • Inaccurate tariff plans
  • Inaccuracy in rates and billing
  • Incorrect billing configuration
  • Incorrect roll-over balances, zoning, rating, and billing

Challenges that arise due to network problems include:

  • The billing/rating system, which does not accept the CDR
  • CDRs with wrong call duration
  • Incorrect business rules
  • Wrong routing of calls
  • CDRs not sent to the required system downstream

Additionally, all telecom transactions are of low value and high volume. This makes it difficult to detect multiple small errors that lead to big financial implications.

How do telecom frauds impact revenue?

With numerous products and services and multiple billing slabs, telecom frauds that cause revenue leakage are becoming harder to detect. Here are some common telecom frauds in brief:

  • International Revenue Sharing Fraud (IRSF):
  • Fraudsters lease a premium number and call a business’ phone system. This generates high call rates for the business. A part of this goes to the fraudster.

  • SIM box fraud:
  • Fraudsters buy a local SIM and make international calls using a SIM box or a GSM gateway. They make international calls at cheaper rates and the telecom company has to bear the losses.

  • PBX hacking :
  • PBX is a company’s internal network that connects to an external phone network. If hackers log in and use the PBX system to make calls, it leads to revenue leakage.

  • Wangiri fraud:
  • A fraudster calls you and disconnects the call. You call back thinking that you missed an important call. However, the call is routed through a high-cost destination that the fraudster controls.
