How to transfer a google apps domain owner?

[DisgruntledOrangatang]

Hey before any links me Authorization code (domain transfers) - Google Apps Help and Unlock domain (GoDaddy and eNom) - Google Apps Help I found them, but I don't want to switch the registrar. I simply purchased a domain for a client as part of our contract agreement, however now it's time for me to transfer the domain to their webmaster. However, I see no way to freaking do this. Right now the domain has my e-mail as the 'main contact' despite the fact that the only user on the domain has other e-mails listed, so somehow the domain ownership is tied to my account. I don't want to get charged again or receive admin e-mails for this, how the freak can I change this?

I just want to untie the domain to my gmail account so the owner can take over payments and be main contact for it, but I can only find information on changing hosts or registrars, neither of what i want to do.

Helpz.
