cPanel is the most popular Control Panel tool on the hosting market. It is feature-rich and it comes with an easy-to-use interface which will supply you with full control over your Internet sites. It is simple to control files, email addresses and databases, view usage statistics, install script-driven applications, and the like. This software is preferred by many web hosting companies, since it also has a reseller counterpart named WebHost Manager (WHM). This instrument will supply you with a web-based graphical interface, through which you're able to take care of a number of server-side settings, set up web hosting packages or new client accounts and adjust their features with just a couple of clicks. You can also install different modules and applications, modify DNS records, brand the cPanel accounts that your customers will get, add and remove features from their Control Panels, etc. cPanel and WHM are supported by the vast majority of billing apps out there, so this is one of the best platforms when you would like to become a reseller.
