CSG Systems

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.
