855 Purchase Order Acknowledgment

edi 855 po acknowledgmentAn EDI 855 Purchase Order Acknowledgment is an electronic version of a phone call or fax that tells the buyer who sent you a purchase order (PO) that you will be filling the purchase order as requested. The buyer then knows that you will be filling the order and shipping the goods as requested by the date requested. An X12 855 Purchase Order Acknowledgment is an example of one kind of EDI transactions.

However, if you will not be able to fill the order, then the 855 Purchase Order Acknowledgment is used to tell the buyer that you will not be able to fill the order. You may be out of stock for the items specified or you may not agree with the Purchase Order business terms.
