Reseller hosting allows anyone to operate a "white label" web hosting business and is used by web professionals to offer web hosting, domain registration, and email services to clients. Most reseller hosting is based on WHMCS, Enom, & ClientExec although ResellerClub has also become extremely popular and has a different approach to domain product services. Resellers normally share hosting space for an unlimited number of domains with fixed bandwidth and storage limits.
One of the most important aspects to look for in reseller hosting plans is the inclusion of free licenses for all of the required software as otherwise WHMCS, Enom, & ClientExec can be expensive to purchase individually. Other web hosting majors provide wholesale credits for resale or their own storefronts that can be deployed with a full range of web hosting products and TLDs for registration. Web hosting reseller accounts are a good place to gain experience and learn more about the industry.
