Japanese telecommunications provider KDDI has selected Oracle Cloud Scale Charging and Billing to modernize its core billing platform as part of a broader digital transformation strategy to improve agility and reduce operational costs, Oracle said.
Under the agreement, KDDI will replace its legacy billing environment with Oracle Cloud Scale Charging and Billing running on Oracle Cloud Infrastructure (OCI). The cloud-native platform is designed to support real-time charging, rating, and billing across mobile, broadband, and digital services.
Modernizing Charging and Billing to Improve Agility and Efficiency
KDDI, Japan’s second-largest mobile provider, is upgrading its core charging and rating platform, which manages how subscribers are charged for services. The platform tracks how users consume mobile services, including data usage, and calculates charges in real time based on individual plans and pricing structures.
The company is replacing a legacy system that was costly to operate and dependent on specialized expertise, which limited its ability to quickly introduce new plans, bundles, or promotional offers.
By adopting Oracle Cloud Scale Charging and Billing, KDDI is moving to a cloud-native platform built on standardized capabilities, reducing the need for extensive custom code with each upgrade or pricing change. Oracle said the move will streamline operations and support more flexible pricing models.
Katsuya Masuda, general manager of the Information Systems Division at KDDI, said, “The implementation of Oracle Cloud Scale Charging and Billing represents a pivotal step in KDDI’s long-term strategy. With Oracle, we can rapidly innovate, confidently scale, and consistently deliver an exceptional experience to our growing subscriber base.”
The shift is expected to simplify system maintenance and better position the company to manage increasing service complexity.
Building a Scalable Billing Foundation for Expansion and New Services
KDDI has already been leveraging its telecommunications foundation, including 5G infrastructure, data-driven initiatives, and generative AI, to expand into adjacent sectors such as digital transformation services, financial services, and energy.
However, its legacy charging and rating platform created operational strain, high infrastructure costs, and growing reliance on specialized resources, constraining further expansion into these adjacent markets.
The new platform is intended to support KDDI’s expanding portfolio by enabling management of complex, high-volume, multi-service billing environments.
Fujitsu will serve as a development and implementation partner, working alongside Oracle’s industry team to deploy the new platform, Oracle said.
By moving its billing systems to a modern cloud platform, KDDI aims to more easily support bundled services, new business lines, and better use customer data.
What This Means for ERP Insiders
Billing modernization is becoming a core enterprise transformation lever. For telecom operators and other subscription-driven businesses, billing platforms are no longer back-office utilities. They directly influence revenue recognition, customer experience, and product agility. ERP insiders should view billing transformation as part of broader enterprise architecture modernization.
Cloud-native charging systems support new business models. As organizations expand into digital services, IoT, energy, or fintech offerings, legacy billing systems often cannot support real-time pricing or bundled service models. Modern, scalable billing infrastructure enables companies to experiment with consumption-based and hybrid pricing strategies without extensive customization.
Revenue systems are converging with enterprise data strategies. Real-time charging and billing platforms generate high-volume operational data that feeds forecasting, analytics, and financial planning. ERP leaders should assess how billing modernization aligns with finance transformation initiatives, including automation, compliance, and margin visibility.
