Cerillion

What Cerillion does

Cerillion is a UK-headquartered, publicly listed (LSE AIM: CER) software company founded in 1999 via management buyout of Logica's Customer Care and Billing division. It provides a pre-integrated BSS/OSS (Business Support Systems/Operations Support Systems) Suite for communications service providers, structured as a platform-plus-modules architecture. The five flagship products — Convergent Charging System (3GPP-compliant), Enterprise Product Catalogue (AI-powered), CRM Plus, Revenue Manager, and Service Catalogue — are complemented by eleven additional modules including Self Service, Mobile App, Service Manager, Business Insights, Output Streamer, Dealer Portal, Interconnect Manager, Network Inventory, Mediator Plus, and Integration Layer. The company serves approximately 70 customer installations across ~45 countries, with named enterprise customers including Three (UK 5G launch), Virgin Media Ireland, Omantel (£42.5M contract), Sure by Beyon, Norlys, Telesur, C&W Communications, MVNX, and Ucom.

The technology foundation is an API-first architecture built natively on TM Forum Open APIs and Open Digital Architecture (ODA), with Diamond-level Open API conformance (50+ certifications, 32 Real World — the highest among BSS/OSS vendors). Recent product releases have layered in AI capabilities: GenAI image recognition and natural language interfaces for product catalogue (v23.2 / v24.1), an MCP Server plus five AI Agents — Billing, Sales, Workflow, Catalogue, Promotions (v25.2, October 2025) — and a proprietary Agent2Agent (A2A) protocol enabling multi-agent coordination across systems (v26.1, April 2026). The platform supports public cloud, private cloud, and on-premises deployment, with deployment options including sovereign hosting at partner data centres such as Oman Data Park.

Cerillion operates a subscription/SaaS revenue model with multi-year enterprise contracts complemented by managed services, implementation, and support. Pricing is quote-based and not publicly disclosed, with the product-based model (all customers on the same core platform with configuration rather than customisation) intended to lower total cost of ownership. The company employs 376 staff globally — concentrated in the UK (115), India (222 at the Pune Global Solutions Centre), and Bulgaria (34 at the Sofia centre of excellence) — with additional presence in the US, Singapore, Oman, Portugal, Belgium, and Malta. Distribution is direct enterprise field sales with no apparent channel partner model.

Direct peers

• Amdocs: The largest independent provider of BSS/OSS software to communications and media companies globally. Competes head-to-head with Cerillion for telecom transformation deals; significantly larger but more fragmented suite offering.
• Netcracker Technology (NEC): Provides end-to-end BSS/OSS digital transformation solutions to Tier-1 CSPs, with a similar pre-integrated Suite pitch. Competes with Cerillion in convergent charging, CRM, and order management for large operators.
• Optiva: Public BSS/OSS vendor focused on telecom charging, billing, and policy management. Closest direct comparable in scale and product scope to Cerillion's convergent charging and revenue management portfolio.
• MATRIXX Software: Cloud-native, 5G-ready charging and monetization platform built for CSPs. Competes with Cerillion's Convergent Charging System and is a benchmark for next-generation, real-time charging architectures.

Broad incumbents

• Ericsson: Telecom equipment giant with a significant OSS/BSS and digital services portfolio. Competes indirectly through its network-adjacent OSS offerings; a much broader incumbent with far greater resources.

• CSG Systems International: Provides BSS solutions including billing, customer care, and digital services management to CSPs globally. Competes with Cerillion across convergent billing and CRM for Tier-1 and mid-tier operators.

Emerging players
