Building Modern Telecommunications Billing Systems: Best Practices for the IP and Software-Defined Network Era

By Jorge Guntanis

Building Modern Telecommunications Billing Systems

Best Practices for the IP and Software-Defined Network Era

Telecommunications billing is broken-not because of accounting, but because networks evolved faster than the systems meant to govern them.

As voice, messaging, and data networks become fully IP-based, programmable, and API-driven, billing systems can no longer function as passive record-keepers. They must operate in real time, alongside signaling and media, enforcing trust, preventing fraud, enabling automation, and supporting commercial accountability at network speed.

Building Modern Telecommunications Billing Systems is a practical, experience-driven guide to designing billing platforms for modern telecom operators. Rather than treating billing as a back-office concern, this book reframes it as a core control plane-one that sits at the intersection of routing, rating, compliance, reconciliation, and real-time decision-making.

Drawing from years of hands-on work operating carrier-grade VoIP, messaging, and IP networks, Jorge Guntanis explores how billing systems must evolve to support:

Real-time rating and policy enforcementInter-carrier settlement and reconciliationFraud detection tied directly to signaling behaviorAPI-first architectures and automationSoftware-defined networks and programmable servicesScalable billing design for VoIP, SMS, and data services

Instead of prescribing specific vendors or tools, the book focuses on architecture, trade-offs, and design patterns that remain valid across technologies, markets, and business models. The emphasis is on how systems actually behave in production-where latency, trust, failures, and money all intersect.

Why this book is different

This is not a theoretical textbook or a vendor whitepaper.

It is written by a practitioner who has designed, deployed, and operated real telecom platforms-working directly with carriers, regulators, and international interconnections. The insights in this book come from operating systems where billing errors are not academic mistakes, but operational, legal, and financial risks.

If you are building or operating telecommunications systems in the IP era, this book will change how you think about billing-and why it belongs at the center of your network architecture.
