I work in the billing department and I do not have a Zendesk login. I need to update our account's payment method or other billing details. How do I do this?
Only the Zendesk account owner can update the payment method and manage billing details on a Zendesk account. If you do not know who the account owner is for your Zendesk account, follow this tutorial to find out: Who is the owner of my account?
Once you've found the account owner, they can follow these guides to update billing information: Billing FAQ and resources.
