Best OSS/BSS (Operations Support/Business Support) Software

Netcracker Technology is a digital transformation software provider, wholly owned by NEC Corporation, that builds BSS and OSS solutions for communications service providers and other industries. Its Netcracker Digital Platform is a cloud-native, decomposable suite covering lead-to-cash business processes, service and network lifecycle automation, digital commerce, charging, and 5G monetization, available as SaaS or on private, public, or hybrid clouds.

Netcracker targets large telecom operators and adjacent industries such as utilities, satellite, finance, and smart cities, supporting business models like B2B2X, Network-as-a-Service, and MVNO-in-a-box. It does not publish public pricing; engagements are structured as enterprise software and services contracts. The company is headquartered in Waltham, Massachusetts, and has been serving service providers for more than 25 years.

CSG builds billing, revenue management and customer engagement software, with deep roots in telecommunications and cable. Its business support system is described as managing more business models on one BSS foundation, which is the central problem it addresses: operators accumulate separate billing systems for consumer, business, wholesale and partner revenue, then cannot reconcile them or launch anything new without touching all of them.

The billing portfolio is unusually granular, and the products are named rather than presented as configuration options. CSG ACP is described as the leading cable biller in North America. Ascendon is the cloud-native SaaS digital monetization platform. Encompass targets complex enterprise telecommunications billing. Billing Manager focuses on accuracy and reducing remediation work, and Bill Explainer uses AI to explain bills so fewer customers call and payments arrive faster, which is a direct and measurable operational saving. Convergent Mediation and Activation unifies 5G usage, charging and activation, while standalone mediation is positioned around predicting issues, stopping revenue leakage and speeding cash. Data Manager handles high-performance data processing underneath.

Revenue that arrives through other parties is treated as a first-class problem. Interconnect billing monetises services and partnerships, and partner billing settles multi-party deals to protect margins, both of which are where operator revenue commonly leaks. Subscription billing supports recurring models, and bill presentment delivers personalised bills across channels. Alongside billing sits a quote-to-cash line including CSG Quote and Order, described as the top ranked CPQ for complex telecommunications B2B, plus Deal Manager for AI-driven pricing and order management for orchestration and fulfilment. Customer engagement covers journey orchestration, journey analytics, customer profiles built on behaviour, agentic AI and consulting. Managed services are offered to offload billing operations and lower total cost of ownership. Pricing is not published.

Amdocs is a technology company that builds software platforms and provides managed services for communications, media, and financial services companies, primarily telecom operators. Its offerings include the Amdocs Product and Pricing Catalog for managing complex pricing and bundling, CatalogONE for telecom offer management, an AI-driven aOS agentic operating system, customer experience and network-focused platforms, and services spanning 5G deployment, eSIM orchestration, and cloud and mainframe modernization.

Amdocs sells to large enterprise customers such as major telecom carriers, and does not publish self-service pricing; engagements are typically structured as software licensing combined with long-term managed services agreements. Its platforms are delivered as SaaS or on private cloud, and it works with operators including AT&T, Telefonica, and Globe.

Ericsson's business and operations support system sits inside a portfolio that also builds the network it runs on, which is the distinguishing consideration. An operator buying OSS/BSS from Ericsson can source radio, core, transport and the systems that monetise them from one vendor. The company frames the stakes bluntly for operators: 5G changes everything, or nothing, and it is up to your OSS/BSS. The supporting phrase, sell, deliver, get paid, is a fair summary of what these systems are for.

The named product areas are specific. Service orchestration handles the automated delivery of services across the network, which is what makes complex 5G offerings deliverable without manual provisioning. Charging and billing covers monetisation, and this is where 5G differs from previous generations, since network slicing and differentiated connectivity only generate revenue if the charging system can price and bill them. Data and analytics, network management and automation, cognitive network solutions and rApps cover the operations side, alongside Cloud Core and cloud infrastructure.

Ericsson also sells the services around the software, reflecting that OSS/BSS transformation is a programme rather than a purchase. OSS/BSS services sit alongside network deployment, network optimisation, Open RAN services, managed network services, consulting, training, data and analytics services and Intelligent Support. Related topics the company publishes on include 5G monetization, autonomous networks, network APIs, network slicing and differentiated connectivity, and it publishes substantial research including the Ericsson Mobility Report and Ericsson Technology Review. The wider portfolio extends to enterprises through private 5G, wireless WAN, mission critical communications and network cybersecurity. Pricing is not published.
