Where an invoice is created via API and the customer uses the Contact Merchant button and Ask a Question form found in the online invoice emailed to them, no user in the organisation is notified by email (as the creator user is 'System Generated').

There needs to be a way either to disable or remove the button, or specify an existing user or email address to be notified in these instances.

At present, a note is created attached to the invoice but users in the organisation are not made aware of its presence, leaving the customer frustrated their message has not been picked up or responded to.
