What is Convergent Billing?

Assume an operator is providing different services mobile voice, fixed voice, data, IPTV, broadband, pre-paid, and post-paid, etc. A customer can have one or more of these services from the same operator. A typical customer would definitely like to have single invoice and single view of his account.

A convergent billing is the integration of all service charges onto a single customer invoice and a unified view of the customer. Customer should call a call center and should get complete account information for all the services opted. Customer receives a single bill and makes a single payment for all the services.

A truly Convergent Billing System should be able to consolidate any number and combination of products and services onto a single bill, regardless of the type of product and market segment, i.e., prepaid and postpaid services.

Another important parameter contributing in convergent billing is a single product and price catalogue for pre-paid as well as post-paid customers.

Benefits of Convergent Billing

Convergent billing would help operators in achieving the following major benefits −

  • Single product and service catalogue gives better time to market and reduced cost of implementation.
  • A unified bill enables cross-service discounts, so that customers who order multiple services can receive preferential pricing.
  • Convergent billing enables multi-service packaging and pricing, whereby existing customers are enticed to add new services and new customers are attracted by innovative service bundles.
  • Centralized customer care and support for both type of customers ( pre-paid and post-paid).
