Is there any other automated affiliate reseller website provider like resellers panel?

Hi! Welcome to WHT! :)

Resellers Panel (http://www.resellerspanel.com) is by far the best automated reseller hosting provider out there, but if you're looking for something different, HostCentric (http://www.hostcentric.com)'s private-label program would be a close runner-up. It operates in the same manner as Resellers Panel, and you can provide Windows, Linux, and Ecommerce hosting plans.

If you are ready to provide support to your customers than there are few more options available.. with the help of softwares you can automate almost everything else.. also this has its own rewards... much higher profits
