I highly recommend prioritizing this feature request. Relying on a single email address for critical billing and payment failure notifications presents a significant operational risk. Here is why this functionality is essential:

Eliminates Single Points of Failure: If the primary contact is on leave, leaves the company, or if the notification is inadvertently caught in a spam filter (which we have experienced), the alert goes completely unnoticed.

Prevents Service Disruption: Missed payment failure notifications can directly lead to unintended account suspensions and critical service downtime for our business operations.

Improves Cross-Departmental Visibility: Payment issues often require coordination between Accounts Payable (for funding) and IT/Telecom Administration (for account management). Allowing multiple contacts ensures both teams are alerted simultaneously so the issue can be resolved proactively.

Adding the ability to configure secondary or multiple billing contacts is a standard and necessary safeguard that will help prevent unnecessary downtime and greatly improve overall account management.
