How do I access an invoice from someone else's account?
Only the account owner or a billing admin can access and download invoices, but they can edit the list of users who receive invoices for every billing cycle. For more information, see the article: Adding or removing invoice recipients.
Reach out to either the account owner or a billing admin of the Zendesk account to be added to this list. For more information, see the article: Finding the account owner.
