EDI 945 - Warehouse Shipping Advice 

The EDI 945 warehouse shipping advice is a type of electronic data interchange transaction set that is used to confirm the completion of a shipment. The 945 is usually sent from a third-party logistics provider (3PL) or remote warehouse, to their client, letting them know that a shipment has taken place. 

What is EDI 945

The EDI 945 - Warehouse Shipping Advice is usually sent by a third-party warehouse or third-party logistics firm to notify a supplier that a shipment has been made. It provides the information needed for the supplier to reconcile the quantity shipped against the quantity ordered, create an invoice and generate an 856 Advance Ship Notice (ASN).

This electronic document complies with the ANSI X12 EDI specification.
