cPanel is the most popular Control Panel tool on the hosting market. It is feature-rich and has an easy-to-use interface which will provide you with full control of your Internet sites. You can easily handle files, e-mail addresses and databases, take a look at usage statistics, set up script-driven apps, and many others. The software is preferred by many website hosting companies, because it also has a reseller counterpart named WebHost Manager (WHM). The aforementioned software instrument will supply you with a web-based graphical interface, via which you'll be able to handle numerous server-side settings, generate web hosting packages or new customer accounts and adjust their features with only a couple of clicks. You may also install different modules and apps, customize DNS records, brand all of the cPanel accounts that your clients will get, create and remove features from their Control Panels, and so on. cPanel and WHM are supported by the vast majority of billing applications out there, so this is among the best platforms if you would like to become a reseller.
