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 90 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.
