By default, invoices are sent to the primary account holder, but if the primary account holder would like to override this and have invoices sent to someone else instead, they can do so by changing the email address listed in the Billing and Payments section of their Vonage API account dashboard.

Note: You can only receive invoices at one email address. You can not add multiple email addresses. As an alternative, you could use an email alias or group email address that has multiple recipients.
