cPanel is the most widely used Control Panel instrument on the web hosting market. It's feature-rich and it comes with an easy-to-use interface which will provide you with full control of your sites. It is easy to handle files, email addresses and databases, view usage statistics, set up script-driven applications, and many others. The software is preferred by many web hosting companies, due to the fact that it also has a reseller counterpart called WebHost Manager (WHM). This tool will offer you a web-based graphical interface, through which you can control lots of server-side settings, set up hosting plans or new client accounts and adjust their features with only a couple of clicks. You may also install different modules and apps, update DNS records, brand the cPanel accounts that your customers will get, add and remove features from their Control Panels, and so on. cPanel and WHM are supported by nearly all billing applications out there, so this is one of the top platforms when you want to become a reseller.
