Usage breakdown

Who trades X12 855 Purchase Order Acknowledgment

855 is used most heavily in grocery & food, retail and building & hardware.

The 855 is the seller's formal response to an 850 purchase order: accept as submitted, accept with changes to price, quantity, dates, or items, or reject. Buyers require it to confirm the order is committed before shipment and to surface availability, pricing, and item discrepancies while there is still time to correct them. Many retail compliance programs mandate it within a defined window, commonly 24 to 48 hours of PO receipt, and failure to send required response documents on time can result in financial penalties under vendor compliance programs. Sent by the supplier or vendor to the buyer that issued the purchase order. A supplier's order management system finishes validating an inbound purchase order against its item master, pricing, and available inventory.
