EDI 855 is the electronic option for issuing a purchase order (PO) Acknowledgment. With EDI 855, a seller confirms the receipt of a PO from a buyer. A key function of the EDI 855 is to “accept” or “reject” the buyer’s request for goods or services based on predefined criteria (e.g. pricing or quantity thresholds). Like the paper version, EDI 855 contains:
• Pricing information
• Sales requirements
• Terms of the sale
• Discount details
• Lead time
• Carrier details

The PO1 segment specifies basic and most frequently used line-item data.

EDI 856, known as the Advance Ship Notice, is passed from the seller to the buyer of an outgoing shipment corresponding to an order. While EDI 855 can accept or acknowledge a customer order, EDI 856 verifies the fulfillment of that order or timing of the order shipment. Some 3PLs can send EDI 856 directly to buyers if the buyer’s contact data is passed to them by the seller through a Delivery Notification (EDI 940).
EDI 865 is a Purchase Order Change Acknowledgment/Request. An EDI 865 would only be used if a seller “rejected” a buyer’s purchase order (for say, incorrect pricing or shipping information) through EDI 855 and the seller resubmitted a purchase order with corrected information using EDI 860 (Purchase Order Change Request). The buyer would then send an EDI 865 to “accept” or “reject” the revised purchase order.
