Add a Transmission Method of 'E-Mail' when creating an invoice. The current options are Paper, Fax, and Electronic. Many vendors now send invoices by E-Mail, not the US Postal Service. Invoices created by EDI transmissions are tagged as 'Electronic' as they should be, even if the vendor emails the invoice to us. What I would like to do is be able to identify an invoice that was emailed to us by a non-EDI vendor. I know it's technically a paper invoice once I print it; but it was received by email and should be identified as such.
