What is an EDI 855 Purchase Order Acknowledgement?

This document has many names. It has been known as a Reverse PO and a Purchase Order Change.

How Do You Set UP an 855 EDI and What Does It Do?

Depending on what agreements are in place between the supplier and retailer you are working with, it can be set up in two common ways: In response to the PO sent from the Retailer. This could be for a ‘acceptance’, ‘rejected’, OR ‘changes’ to the PO. Or it could be set up as a Reverse PO, where Seller/Supplier is telling the Buyer/Retailer what is on the Order and it’s not in response to an 850. It is the document that tells the Retailer what is going to be sent, no original PO is needed as this document can serve as the PO. One thing remains the same regardless of setup, it will always be sent from the seller/supplier and received by the seller/buyer. Essentially eliminating the need for a phone call, email, or get this, a fax by the seller to confirm receipt of product by line item.
