cPanel is the most popular Control Panel instrument on the website hosting market. It's feature-rich and it comes with an easy-to-use interface which will offer you full control of your websites. It is simple to handle files, e-mail addresses and databases, view usage statistics, install script-driven applications, etcetera. The software is preferred by many web hosting companies, since it also has a reseller counterpart called WebHost Manager (WHM). This instrument will give you a web-based graphical interface, via which you are able to handle a number of server-side settings, create hosting packages or new customer accounts and modify their features with only a couple of clicks. You may also install different modules and apps, change DNS records, brand the cPanel accounts that your clients will get, create and remove features from their Control Panels, etc. cPanel and WHM are compatible with nearly all billing applications out there, so this is one of the best platforms in case you want to become a reseller.
