BSS / OSS
Business Support Systems and Operations Support Systems are the software backbone of telecommunications providers — the billing, network management, and customer management platforms that every telecom depends on and almost every telecom has outgrown.
In telecommunications, OSS (Operations Support Systems) manage the technical operations of the network — network inventory, fault management, configuration management, and performance management. BSS (Business Support Systems) manage the commercial operations — customer management, product catalog, order management, billing, and revenue assurance. Together, BSS/OSS represent the full software stack that enables a telecom to sell services, provision them on the network, monitor and manage network performance, and bill customers correctly.
BSS/OSS modernization is one of the largest categories of technology investment in global telecommunications. The legacy BSS/OSS landscape is a graveyard of custom-built systems and vendor platforms from the 1990s and 2000s that were not designed for 5G network slicing, real-time charging, API-based product configuration, or the customer experience expectations of the digital age. Telcos are running 5G networks on billing systems built for voice calls — and the impedance mismatch is visible in every customer interaction.
The compliance requirements for telecom BSS/OSS are substantial and underappreciated. CALEA (Communications Assistance for Law Enforcement Act) requires telecom networks to support lawful intercept capabilities — engineering requirements that must be built into network management systems. GDPR and CCPA apply to customer data in CRM and billing systems. PCI-DSS applies to payment data. NIS2 (in the EU) and the Telecommunications Security Act (in the UK) impose cybersecurity requirements on the systems that manage network infrastructure. Telecom BSS/OSS transformation projects must be compliance-aware from the architecture phase.
We architect BSS/OSS modernization for telecommunications providers — designing cloud-native replacements for legacy billing and network management platforms, implementing real-time charging for 5G service models, building API-first product catalog and order management systems, and ensuring CALEA, GDPR, and NIS2 compliance is built into the architecture from day one. Our teams understand the operational risk of BSS/OSS transformation and build migration strategies that keep revenue flowing throughout the transition.
