Angular/C#
Cerillion had built an end-to-end, composable BSS/OSS platform that bundled rating/charging, convergent billing, customer management, catalog/product configuration, mediation and payment orchestration into a pre-integrated offering. Customers (mobile, fixed, cable, MVNO/MVNE, utilities and subscription businesses) used Cerillion to consolidate legacy stacks, launch new bundles and subscription services, and automate billing and collections. The company offered deployment flexibility (SaaS, private cloud, on-prem) and professional services to accelerate time-to-value and reduce integration risk.
Realtime/near-real-time rating & mediation
Processing high-volume usage events and applying accurate rating/charging in near-real-time placed load on mediation and charging pipelines.
Legacy consolidation & migration risk
Migrating customers from fragmented legacy BSS stacks to a unified platform required careful data migration, reconciliation and cutover safeguards.
Regulatory & billing accuracy demands
Meeting operator SLAs, tax rules, multi-currency invoicing and audit requirements increased operational and testing complexity.
We standardized product and catalogue modeling so operators could launch bundles and subscription offers without bespoke code changes. We implemented a streaming mediation and rating pipeline with idempotent workers and reconciliation so usage-based billing ran accurately at scale. We executed careful migrations using simulation runs and parallel billing to avoid revenue leakage during cutovers. We delivered integration adapters (TM Forum-aligned) and payment automation, and we ran managed operations with monitoring and SLAs so clients achieved predictable performance and compliance.
1. Convergent Billing & Charging
Cerillion supported convergent, subscription and usage-based billing that unified postpaid/prepaid, recurring and one-off charges into a single ledger.
2. Skyline SaaS for Subscriptions
The Skyline product automated subscription billing, payments and renewals for SaaS and subscription businesses, speeding up cash collection cycles.
3. CRM & Customer Management
The platform provided a full CRM with customer lifecycle, order management and entitlement controls to manage subscribers and accounts.
4. Pre-integrated BSS/OSS Suite
Cerillion delivered a pre-integrated stack (billing, charging, mediation, catalogue, product configuration) designed for rapid implementation and standards compliance.
5. Payments & Collections Automation
The product included payment orchestration, invoicing and reconciliation components to automate cash flows and reduce DSO.
The solution improved user engagement, and a pilot adoption rate exceeding expectations.
Implementations reduced billing cycle time and manual reconciliation, which lowered operational overhead and improved cash collection. Migration and reconciliation tooling eliminated many data inconsistencies and decreased billing exceptions and customer disputes. Real-time rating and mediation increased the operator’s ability to launch usage-based and bundled monetization, driving new revenue streams. Overall, the unified BSS/OSS deployments improved operational efficiency, reduced total cost of ownership and accelerated time-to-market for new services.
