cPanel is the most widely used Control Panel tool on the website hosting market. It is feature-rich and it has an easy-to-use interface that will provide you with full control over your Internet sites. You can easily control files, email addresses and databases, view usage statistics, set up script-driven apps, and so on. The software is preferred by many web hosting companies, because it also has a reseller counterpart called WebHost Manager (WHM). This software instrument will offer you a web-based graphical interface, via which you're able to handle a number of server-side settings, generate web hosting packages or new customer accounts and change their features with just a couple of clicks. You can also install different modules and applications, customize DNS records, brand all the cPanel accounts that your clients will get, create and remove features from their Control Panels, etcetera. cPanel and WHM are supported by the vast majority of billing applications out there, so this is among the best platforms in case you would like to become a reseller.
