Is it possible to run multiple reseller plans on 1 domain. For example if I buy reseller plans from 2 different Companies and want to resell to my Clients. Can both the group of my clients have separate billing URLs (in my domain)? Most Reseller Hosting Companies provide "http://mysite.com/whm" as the URL for managing my clients. If I have 2 reseller plans on 1 domain how would this work?
That sounds like it would be unecessarily complicated. Why would you need multiple reseller accounts anyway? If you outgrow a reseller plan, then move on to VPS or dedicated.
The source I am planning to buy reseller package offers 4 different reseller plans. However the first plan offers best deal on bandwidth compared to other higher plans. So I was thinking to buy the first plan itself once I resell all the space on the 1st server/package. Your suggestion makes sense when I get more no. of customers that would be more aptful to run on VPS/dedicated server. However I found the solution... My Hosting Company said that I could access additional WHMs directly thru the temporary URL (that is via the IP address). Also I found the billing software WHMCS could handle multiple servers.
