You can access a domain’s transfer token at https://admin.google.com/TransferToken. Once you authenticate with a valid admin username and password, this page contains a token URL which allows you to transfer the management of your Google Apps account to a new Google Apps Authorized Reseller.
After generating a new token, give the token’s alphanumeric code to your reseller who then completes the transfer for you. Remember, transfer tokens expire 5 days after being generated.
Once the transfer is completed, your transferred account will be managed and billed through the reseller. For Google Apps for Business accounts purchased directly online from Google, no future charges will accrue on the direct billing account. For Google Apps for Business accounts not purchased online from Google, contact Support.
