Dear all,

I am wondering if is it possible to use CPanel or Plesk in 5(add a new servers as the business grows) leased dedicated server...And I have one admin/automated billing system/support system etc?

eg: If i have 2 server for shared customers 1 server for vps customers 1 server for resseler customers and 2 server for dedicated...Can I manage all in one place...
Can customer choose from my site which type of account(vps,dedicated,shared etc.) want and automated create/billing the customer??? Such as doing a big companies???

Many thanks

One system that does it all in one place and out-of-the-box is H-sphere. From one Control Panel you can manage customer billing, support tickets, provisioning, shared, reseller, vps, dedicated, cluster/separate servers (db, mail, web), expand as you grow, offer windows, linux, exchange etc.

Otherwise, it depends on your billing/provision system. WHMCS supports many modules and you can achieve creating accounts on separate servers depending on the plan. But of course it does not provide any interface with management of servers (this is what control panels do.)

Where i can find this modules for WHMCS?
Which you prefer?

WHMCS does not have a plugin for H-sphere. I don't know if its planned...

However you could use WHMCS as the central interface which than then crate cPanel & Plesk accounts on the respective servers. Like Tony said you would still have to login to each server's control panel to perform changes etc.
