cPanel is the most widely used Control Panel tool on the web hosting market. It's feature-rich and it comes with an easy-to-use interface which will give you full control over your web sites. It is simple to take care of files, e-mails and databases, take a look at usage statistics, set up script-driven apps, and many others. The software is preferred by many hosting companies, as it also has a reseller counterpart named WebHost Manager (WHM). This software instrument will offer you a web-based graphical interface, via which you can manage many server-side settings, generate website hosting packages or new customer accounts and adjust their features with just a couple of clicks. You may also install different modules and apps, modify DNS records, brand all the cPanel accounts that your customers will get, add and remove features from their Control Panels, and many others. cPanel and WHM are supported by almost all billing applications out there, so this is one of the best platforms when you would like to become a reseller.
