The Shared Web Hosting plans are for a single owner; we provide one control panel for all of your domains. We do not support reselling on the Shared plans.
The Reseller Hosting plans are intended for an owner who wants to sell hosting; we provide an unlimited number of control panels, one for each domain. If you need multiple SSL certificates or multiple IP addresses, you must choose a Reseller account. If you want WHM and control over DNS zones, you must choose a Reseller account.
