COS Systems delivers a cloud-based BSS/OSS platform purpose-built for broadband operators. Operators choose COS Business Engine to run full retail ISP operations — subscriber management, billing, provisioning, and field service — or COS Wholesale Engine to orchestrate multi-provider Open Access networks. COS FSM and COS Prospector extend the platform with automated field service management and door-to-door demand aggregation, so operators can sell faster, scale better, and automate everything.
