cPanel is the most widespread Control Panel instrument on the web hosting market. It is feature-rich and it has an easy-to-use interface that will offer you full control of your web sites. It is easy to control files, emails and databases, view usage statistics, set up script-driven applications, etcetera. This software is preferred by many hosting companies, since it also has a reseller counterpart called WebHost Manager (WHM). This instrument will supply you with a web-based graphical interface, through which you'll be able to control lots of server-side settings, generate hosting plans or new client accounts and adjust their features with just a few clicks. You may also install different modules and apps, update DNS records, brand all the cPanel accounts that your customers will get, create and remove features from their Control Panels, etcetera. cPanel and WHM are supported by almost all billing apps out there, so this is one of the top platforms when you want to become a reseller.
