To send a purchase order, first navigate to the Purchase Orders tab. Click the Send icon (paper airplane) under Actions in the same row as the PO you would like to send.
A pop-up window will appear. Enter the vendor email address and any other address you would like to copy (CC) in the related field and press the blue Send button.
Please note that you can only send a PO one time from the application. If you would like to resend the PO, you can download it and send it through your email.
