i would like to become a domain&hosting reseller at resellerzoom with modernbill or clientexec but there are a few obscurities.

Kindly tell me..
1.If i signup at resellerzoom with my domain, how it works when the webspace/traffic which i sell comes to the end?(no more upgrade available)
Must i signup with another domain and register a new account ? How that works with modernbill/clinetexec ? and how i sell this webspace under my root domain?

Where is my error in reasoning ??

Thank you very much and excuse my bad english

Not sure how it works at ResellerZoom, but sometimes if you work your way up to that point, your provider will work with you to customize a package for you. You don't need another domain. Your other solution at that point might be to look at your own servers. My suggestion would be to contact ResellerZoom sales and ask them.

Hope I've been of some help ;).

Thank you for your quick response!!
unfortunately i dont have the experience to setup my own server but maybe one day my dream come true...;-)
But is that possible to sell webspace/traffic from another server under my root server? So that the clients are register & buy under server1 and become there webspace from server2 ?

hmm very likely i fail to understand myself :-)
for me in english is was hard to explain
