cPanel is the most widespread Control Panel tool on the website hosting market. It's feature-rich and has an easy-to-use interface that will give you full control over your web sites. It is simple to take care of files, emails and databases, view usage statistics, install script-driven apps, etcetera. The software is preferred by many website hosting companies, since it also has a reseller counterpart called WebHost Manager (WHM). This software tool will provide you with a web-based graphical interface, through which you'll be able to control lots of server-side settings, create hosting plans or new client accounts and adjust their features with only a couple of clicks. You may also install different modules and apps, change DNS records, brand all the cPanel accounts that your clients will get, add and remove features from their Control Panels, etcetera. cPanel and WHM are supported by almost all billing applications out there, so this is among the best platforms if you want to become a reseller.
