A Control Panel is a web-based interface using which you can manage various aspects of your world-wide web presence. For example, you can set up or change website files, create and check email messages, handle databases, check visitor statistics and so on. These things are done through buttons and menus inside an internet browser and the Control Panel could also be called ‘back office’, i.e. the admin area associated with your hosting account. Most Control Panels out there will allow you to control all hosting-related matters, but you'll usually need a different system to handle payments or to get a new domain name in case 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 an issue also, or you may need to use a third system.
