cPanel is the most widespread Control Panel tool on the hosting market. It is feature-rich and it has an easy-to-use interface that will offer you full control over your Internet sites. It's easy to manage files, emails and databases, take a look at usage statistics, set up script-driven applications, and many others. The software is preferred by many hosting companies, since it also has a reseller counterpart named WebHost Manager (WHM). The aforementioned tool will offer you a web-based graphical interface, through which you are able to control a lot of server-side settings, set up web hosting packages or new customer accounts and adjust their features with just a few clicks. You may also set up different modules and apps, adjust DNS records, brand all the cPanel accounts that your customers 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 one of the top platforms when you would like to become a reseller.
