EDI 855 - Purchase Order Acknowledgment

The EDI 855 allows sellers to communicate the status of an order to a buyer. The seller can confirm, reject, or report any changes or issues with the order to the buyer.

The EDI 855 has several functions, including:
– Acknowledges receipt of a purchase order from a buyer
– Communicates seller’s intent to fulfill the order
– Reports any errors on the order, such as inaccurate pricing or part numbers
– Communicates issues with fulfilling the order, such as insufficient quantities
– For drop-ship orders, provides retailers with delivery status information to share with consumers
