If a user has another point of contact handling their invoices and payments, they may ask to send invoices to an external party. As this external party may not be a 'user' in your organization, you might like to take the approach of designating a non-user invoice contact.
Note: Invoice reminders will only be sent if you have enabled them under
Navigate to the Users screen (click on Teams if you're searching for a team)
Locate the user or team for which you want to add an invoice contact
From the side panel, click in to 'Account'
Scroll down to 'Billing details'
Enter the email address under 'Additional email'
Once this is done, any invoices associated with the relevant user or team will be sent to this email address as well as the user or team admin. In addition these details will show up on the user or team's invoice.
