SolidState is a Web-based billing and customer management solution for Web hosting providers. It is written in PHP, uses MySQL, is fully templated with Smarty templates, and is built on-top of a modular framework with support for third-party payment gateways and domain registrars. There are two interfaces: an order/signup interface for new and existing customers to place orders for hosting services and domains, and a manager interface for administering customers, services, and orders.
