cPanel is the most popular Control Panel tool on the hosting market. It is feature-rich and it features an easy-to-use interface that will supply you with full control of your Internet sites. It is easy to control files, e-mails and databases, view usage statistics, install script-driven apps, and the like. The software is preferred by many website hosting companies, because it also has a reseller counterpart named WebHost Manager (WHM). This instrument will provide you with a web-based graphical interface, through which you are able to control a lot of server-side settings, create web hosting plans or new customer accounts and modify their features with only a few clicks. You can also set up different modules and applications, update DNS records, brand the cPanel accounts that your clients will get, add and remove features from their Control Panels, etcetera. cPanel and WHM are supported by nearly all billing apps out there, so this is among the best platforms if you want to become a reseller.
