cPanel is the most widespread Control Panel tool on the web hosting market. It is feature-rich and it has an easy-to-use interface that will give you full control of your sites. You can easily control files, e-mails and databases, view usage statistics, set up script-driven apps, and many others. The software is preferred by many website hosting companies, as it also has a reseller counterpart named WebHost Manager (WHM). This instrument will offer you a web-based graphical interface, via which you'll be able to handle a lot of server-side settings, set up website hosting plans or new customer accounts and change their features with only a few clicks. You may also set up different modules and applications, modify DNS records, brand all of the cPanel accounts that your customers will get, create and remove features from their Control Panels, and so on. cPanel and WHM are supported by almost all billing applications out there, so this is among the top platforms when you want to become a reseller.
