A shared web hosting plan offers everything you need to create and maintain a website. Shared hosting plan subscribers are provided with one cPanel control panel through which they can manage all of their domains. While you can operate a number of domains and/or subdomains on a single shared hosting plan, the plan does not support reselling.
Reseller hosting is a plan designed to let you sell web hosting packages to your own clients. You, in effect, become the owner of a web hosting business. A HostPapa reseller hosting package includes cPanel control panels for your customers. As the reseller host, you may use WHM control panel to manage all your accounts.
