Billing accuracy with the QiTASC charging test services

Challenges of charging and rating testing

Traditional billing validation is complex because of the number of factors involved: diverse technologies, roaming scenarios, different service types, and time-dependent tariffs. Accurate charging is one of the most critical aspects of telecommunications. Even small billing discrepancies can result in significant revenue leakage, compliance issues, and customer dissatisfaction.

Common challenges include:

• Validating real-world scenarios such as dropped calls, network handovers, or partial sessions

• Ensuring consistent charging across multiple networks (2G–5G, WiFi, IoT)

• Testing peak/off-peak tariffs, roaming agreements, and promotional pricing

• Managing the high volume of charging data records (CDRs) generated across use cases

Many test automation companies focus primarily on functional testing of services rather than deep validation of charging accuracy. Their platforms may simulate usage but often lack comprehensive billing verification, detailed tariff checks, or analysis of discrepancies.

QiTASC differentiates itself with its end-to-end charging validation. Unlike generic automation tools, QiTASC integrates automated CDR collection, billing analysis, and scenario simulation in a single framework. This makes it possible to test real-world use cases at scale while pinpointing revenue leakage before it reaches the customer.

Comprehensive charging validation

QiTASC provides comprehensive automated testing for all billable telecommunications scenarios with complete end-to-end verification of charging data records (CDRs). Our advanced test automation platform executes real-world communication scenarios and automatically collects charging data for use case-specific validation. We control mobile devices, VoIP equipment, emulate POTS and ISDN systems, and deploy virtual SIP phones to simulate any communication scenario across all network technologies.

Our testing covers complete billing verification across 2G/3G/4G/5G networks and WiFi connections, ensuring accurate charging for voice, data, SMS, and value-added services. With automated iteration through all communication channels, we deliver reliable charging validation that protects revenue streams and ensures billing accuracy for telecommunications providers and IoT service operators.

Key use cases

QiTASC validates a broad range of charging scenarios including voice calls, VoLTE, mobile and fixed data services, SMS/MMS (including premium and international), USSD sessions for mobile money and banking, value-added content, IVR systems, conference calls, roaming, and multi-party billing arrangements. This breadth ensures operators can trust that every interaction is billed correctly, regardless of complexity.

Our solution with verification features

QiTASC offers a turnkey charging validation service without requiring heavy infrastructure investment. Operators benefit from a dedicated telecom environment with devices, VoIP, and virtual systems, supported by expert teams who design tailored test cases and ongoing validation programs. This reduces complexity while ensuring enterprise-grade testing capabilities.

The platform simulates edge conditions and billing-critical events often overlooked by others. Automated CDR collection is matched against expected tariffs to flag discrepancies in real time. Full simulation of handovers, poor connectivity, and SIP variations ensures accuracy even under stress conditions. Detailed reporting and time-based validation—accounting for time zones and peak/off-peak tariffs—give operators a transparent view into their billing performance.
