How 855 Works
EDI 855 P.O. Acknowledgement
The 855 Purchase Order Acknowledgement is used by the supplier to indicate to the buyer that their purchase order will be filled as requested. Specific details such as items, price, and quantities delivered will be represented in the document. The buyer then knows you will be filling the order and shipping the goods as requested, by the date requested, or that you will be unable to do so for some reason, such as being out of stock, or not agreeing to the terms of the purchase order.

What makes up the EDI 855?
Elements could include vendor number, purchase order number, address information (street, city, state etc.), and an acknowledge/reject indication, identical to a paper or faxed Purchase Order Acknowledgement.
How EDI 855 is used?
An 855 Purchase order acknowledgement is sent by the supplier after receiving the 850 Purchase Order from the buyer.
