A Control Panel is a web-based interface where you can control different aspects of your web presence. For instance, you can set up or change site files, create and check email messages, manage databases, check visitor stats and so forth. Those things are done via buttons and menus in a browser and the Control Panel could also be called ‘back office’, i.e. the admin area associated with your Internet hosting account. Most Control Panels these days will enable you to handle all hosting-related matters, but you will normally require a different system to control payments or to get a new domain if the company offers domain registrations. With respect to the platform they utilize, you could be able to use the billing account to open a support ticket to ask a question or to resolve a problem as well, or you might have to employ a third system.
