PortaOne has been developing billing, business support systems, and cloud telephony software for communication service providers for over two decades. We’ve helped over 500 forward-thinking telcos in 100+ countries be market leaders while keeping the total cost of ownership for their business support system under control. We offer an unlimited lifetime license, and our open-architecture platform lets our customers quickly develop new services in-house. We give access to the source code to our customers to ensure security validation and transparency.
