cPanel is the most widely used Control Panel instrument on the web hosting market. It's feature-rich and it comes with an easy-to-use interface which will supply you with full control over your sites. It is simple to manage files, e-mails and databases, view usage statistics, install script-driven applications, and so on. This software is preferred by many hosting companies, because it also has a reseller counterpart named WebHost Manager (WHM). The aforementioned software tool will offer you a web-based graphical interface, via which you'll be able to manage a number of server-side settings, generate website hosting packages or new client accounts and adjust their features with only a few clicks. You can also install different modules and apps, modify DNS records, brand the cPanel accounts that your customers will get, create and remove features from their Control Panels, and many others. cPanel and WHM are compatible with nearly all billing applications out there, so this is one of the best platforms in case you want to become a reseller.
