We have move our accounts payable to evernote. As we are in construction we receive thousands of invoices each year and we have found evernote to save many hours in retrieving invoices and processing payments. We would like to have a duplicate remover feature that is able to identify the same note image or an identical pdf. This would help us immensely as it reduces the chance of a duplicate invoice payment. Many suppliers and invoicers sometimes resend the same invoice. I have attached an image of the invoice work flow process to show the evernote developers how we have adopted our invoice processing into evernote.
