Seshnova
Seshnova is a cloud-native prepaid billing and session-enforcement platform for operators who can't afford to bill after the fact. It rates usage in real time, tracks entitlements across customers and products, and enforces hard cut-off the moment credit hits zero — no overspend, no reconciliation, no negative balances.
Built on FreeSWITCH, CGRateS, and Kamailio, Seshnova was purpose-built for prepaid telecoms: real-time credit control for prepaid voice, hard enforcement for calling cards, and hands-on migration tooling for operators moving off legacy platforms like Digitalk, PortaOne, and Telinta.
The same rating-and-enforcement loop extends to any metered service — EV charging, parking, API monetisation, IoT connectivity, and SaaS usage billing.
Multi-tenant, carrier-grade, and fully auditable. When entitlement ends, the session ends.
