cPanel is the most popular Control Panel instrument on the web hosting market. It's feature-rich and has an easy-to-use interface which will offer you full control of your websites. It is simple to take care of files, email addresses and databases, take a look at usage statistics, install script-driven applications, and many others. The software is preferred by many hosting companies, because it also has a reseller counterpart named WebHost Manager (WHM). The aforementioned software tool will provide you with a web-based graphical interface, through which you'll be able to handle lots of server-side settings, create hosting packages or new customer accounts and modify their features with only a few clicks. You can also install different modules and applications, change DNS records, brand all of the cPanel accounts that your clients will get, create and remove features from their Control Panels, etc. 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.
