cPanel is the most popular Control Panel instrument on the website hosting market. It's feature-rich and it has an easy-to-use interface that will give you full control of your sites. It's easy to handle files, email 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). This software instrument will offer you a web-based graphical interface, through which you are able to manage lots of server-side settings, generate web hosting packages or new customer accounts and adjust their features with only a few clicks. You may also install different modules and applications, change DNS records, brand the cPanel accounts that your clients will get, add and remove features from their Control Panels, and many others. cPanel and WHM are supported by nearly all billing applications out there, so this is among the best platforms if you would like to become a reseller.
