Should you build or buy Telecom Revenue Assurance & Fraud Management (RAFM)?
Telecom Revenue Assurance & Fraud Management (RAFM) software detects and closes the gaps between what a carrier's network generates in revenue and what actually gets billed and collected, while simultaneously identifying and blocking fraudulent usage patterns — SIM-box bypass, roaming manipulation, interconnect fraud — before they erode margin. It operates on CDR streams and mediation data, applying anomaly detection, reconciliation, and case management across the subscriber base.

Separate carrier-specific detection from the revenue-assurance workflow around it. Internal models may fit your traffic patterns; reconciliation, settlement, case management, and maintained controls still need an operating owner.
Build it, buy it, or bridge?
When building makes sense
Consider an internal build for network-specific fraud detection and analyst prioritization. Production detection work supports part of the category. It does not establish replacement of the revenue-assurance and settlement core.
When buying makes sense
Buying earns its keep when you need revenue reconciliation, settlement workflows, typology libraries, case management, and audit records. Compare the vendor’s coverage with the staff, integrations, and controls an internal option would need. Custom extensions can remain useful without replacing the core.

How is AI changing the RAFM market?
AI can help with fraud detection on carrier data. Revenue reconciliation, settlement, case management, and maintained controls remain separate parts of RAFM. Test a custom detector against its operating role before extending its results to the whole suite.
