cPanel is the most popular Control Panel instrument on the hosting market. It's feature-rich and it features an easy-to-use interface which will give you full control over your web sites. It's easy to take care of files, e-mail addresses and databases, view usage statistics, install script-driven applications, and many others. This software is preferred by many hosting companies, due to the fact that it also has a reseller counterpart named WebHost Manager (WHM). The aforementioned software tool will give you a web-based graphical interface, via which you'll be able to handle a lot of server-side settings, create website hosting plans or new customer accounts and modify their features with only a few clicks. You can also install different modules and apps, update DNS records, brand all of the cPanel accounts that your clients will get, add and remove features from their Control Panels, etc. cPanel and WHM are supported by nearly all billing applications out there, so this is among the top platforms in case you wish to become a reseller.
