National Billing Challenges

Context & Insights

The Challenge

Managing billing at a National Scale (15,000+ premises) for ministries and government agencies. The legacy infrastructure struggled with flexibility and could not easily integrate with TM’s existing Business Support Systems (BSS/OSS).

The Gap

Manual processing of “Pay-As-You-Use” data resulted in latency and potential calculation errors. The system required 100% accuracy for complex variables like Late Delivery (LAD) and Penalty charges, which manual methods could not guarantee.

The Goal

To replace manual bottlenecks with a Real-Time Billing Engine capable of ingesting vast data volumes with zero error margin.

Automated Financial Logic

The Strategy

Phase 1

Intelligent Ingestion:

Unified real-time streams from SAMS, ISIM, and MyGovServ via Argo Workflows.

Phase 2

Core Automation:

Deployed the AQ-Rate Engine to automate PAYU, Fixed Charges, and Penalties instantly.

Phase 3

Ironclad Governance:

Secured data with Apache Ranger to achieve full ISO/IEC 27001 compliance.
