cPanel is the most widely used Control Panel instrument on the web hosting market. It's feature-rich and has an easy-to-use interface which will give you full control over your sites. It is easy to manage files, e-mails and databases, take a look at usage statistics, set up script-driven apps, and the like. This software is preferred by many website hosting companies, as it also has a reseller counterpart called WebHost Manager (WHM). The aforementioned instrument will offer you a web-based graphical interface, via which you are able to manage lots of server-side settings, create website hosting packages or new client accounts and modify their features with just a couple of clicks. You may also set up different modules and applications, modify DNS records, brand all the cPanel accounts that your customers will get, add and remove features from their Control Panels, and so on. cPanel and WHM are compatible with the vast majority of billing applications out there, so this is one of the top platforms if you want to become a reseller.
