How can I update a current wireless business account name and billing address?

I have an existing wireless business account with several devices and need to update the business account name and billing address.   There will NOT be changes to the users, account managers, devices, device names etc..  Only reflects the account name and billing address.  I found where I can change the profile name and address online, but I believe this is only how it's viewed online and not how it appears on billing statements???  is that correct?  Thank you.
