Since sending invoices to customers is mandatory, I understand there’s an option to email invoices directly to the customer’s encrypted email ID.

@Noor_Amazon_

Would Amazon acknowledge this action and automatically update the order status to reflect that the invoice has been sent?

I have tried with one order but still the order shows need to upload an invoice.

Does anyone have a more efficient solution besides using an API or manually uploading each invoice?
