Invoice and Tax Invoice
These are the current operating document types.
From order to uploaded invoice
The Windows app connects to Seller Central, reads order details, prepares the correct document, saves the PDF, then uploads it through the verified workflow.
Credit notes are local-only for now
The app supports Credit Note and Tax Credit Note locally; they are not currently available through the public website workflow.
PDF files stay local
Amazon invoice PDFs generated by the app are saved on the customer's device.
