cPanel is the most widely used Control Panel tool on the web hosting market. It's feature-rich and it features an easy-to-use interface that will supply you with full control over your web sites. It's easy to take care of files, e-mail addresses and databases, view usage statistics, set up script-driven apps, and so on. The software is preferred by many hosting companies, because it also has a reseller counterpart named WebHost Manager (WHM). The aforementioned tool will supply you with a web-based graphical interface, via which you can take care of a lot of server-side settings, create web hosting packages or new customer accounts and change their features with only a couple of clicks. You can also install different modules and apps, modify 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 apps out there, so this is among the top platforms in case you would like to become a reseller.
