What is Telecom Billing?
Telecom billing is simply how telecom companies bill their customers based on their consumption of service. The function/content/duties include collecting usage data on calls, texts, internet data usage, and subscriptions, performing calculations based on rate plans, taxes, and discounts, and generating a bill or invoice.
Core Functions:
Data collection
Charging and Rating
Invoice and Billing
Revenue Assurance and Fraud Management
Payment Processing
Customer Care Integration
Basic Components of a Telecom Billing System
Mediation System
Ingests raw data records (CDRs/XDRs) from network elements, such as switches and routers, and standardises the data for billing purposes.
Rating Engine
Applies tariffs or rate plans to the usage data, ie, taking 1GB of mobile data and converting that into a charge for the customer based on the charge on the customer plan.
Billing Engine
Performs a determination of charges ie, recurring charges (subscriptions), one-time charges, usage-based charges on behalf of the party.
Customer Management (CRM)
Enter customer profiles, plan attributes, preferences, and payment history.
Invoice Generator
Generates an itemized bill which can be delivered via Email/SMS/apps or printed.
Revenue Assurance and Fraud Detection
Prevent revenue leakage by cross-checking all parameters.
Types of Telecom Billing
Prepaid Billing
Customers pay for the right to use the service. Usually, a real-time charging system applies mostly to mobile and data services.
Postpaid Billing
The customer uses the service, then receives a bill. Invoices are automatically generated at the end of the billing cycle.
Convergent Billing
Convergent billing provides a single bill for multiple services. Examples of services are mobile, broadband, TV, and VoIP. Convergent billing will become important in 2025 because a lot of customers are looking for digital bundles of offerings.
