Please note we buy most of our new domain names under PDR registrar at the moment of writing this helpdesk article. They provide one domain name panel where all your orders are processed thus individual domain name basis control panel is not possible, as your email id is your username, and whatever domains you have with us under PDR registrar will be under that specific one panel only.
We have a separate domain name reseller program, and suggested in case you want to have a domain name reseller ac where you can offer a separate control panel to your clients.
