Customer moving, can I transfer the service I used for them to their own account?

I have a bunch of services with mxroute, I love it that much. I bought one recently for use by one client, but that client is now moving elsewhere and won’t be using me to manage their email. However, they might be willing and able to stick with mxroute if I can transfer the service I paid for to their account,a nd then they continue with it, paying the renewal , etc.
Is this possible?

Hi Shane, @ssc

Due to the inclement weather in MXRoute’s location it may be a day (or three) before they can respond to you here. Just a heads up!
