Expedient can interface with transport companies using Cargo Office so they can send a PDF of the Proof of Delivery and Expedient will store the PDF to the Job Documents folder.
The Administration > Customer Masterfile, Carrier tab stores the interface details with each Carrier. These details can only be updated if you are a Superuser.
On receipt of the email from the Carrier attached the PDF Expedient will check the reference number provided by the Carrier is correct and can be linked to an Import Job. If the job number can be found Expedient will store the POD in the Job Documents folder (if your site uses Expedient to store Documents).
