Yes. cPanel & WHM supports root users that can create and modify any domain and have access to all features of the cPanel & WHM interfaces.
We also support resellers, which are used for web hosting resellers to manage their own customer's accounts. However, you can easily tweak reseller access so they only have privileges to suspend or unsuspend domains. Resellers have access to the cPanel interface and a limited subset of the functionality of the WHM interface.
Lastly, there is the hosting account owner, who has an account in the cPanel interface and can manage most aspects of a website by themselves (within boundaries that the reseller or root user sets).
