cPanel is the most widely used Control Panel tool on the hosting market. It is feature-rich and has an easy-to-use interface that will offer you full control over your websites. You can easily handle files, e-mails and databases, view usage statistics, set up script-driven apps, and many others. This software is preferred by many hosting companies, since it also has a reseller counterpart named WebHost Manager (WHM). This instrument will provide you with a web-based graphical interface, through which you'll be able to control lots of server-side settings, generate website hosting plans or new client accounts and change their features with only a couple of clicks. You may also install different modules and applications, change DNS records, brand all of the cPanel accounts that your customers will get, create and remove features from their Control Panels, etc. cPanel and WHM are compatible with almost all billing applications out there, so this is among the best platforms if you wish to become a reseller.
