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.
When it fires: A supplier's order management system finishes validating an inbound purchase order against its item master, pricing, and available inventory.
- Acknowledgments sent after the buyer's required response window, commonly 24 to 48 hours, exposing the supplier to compliance penalties.
- PO number or line references that do not match the original 850, so the buyer's system cannot tie the acknowledgment back to the order.
- Inaccurate product identifiers or prices echoed back on the acknowledgment, creating discrepancies that persist into the ship notice and invoice.
- Missing or inconsistent acknowledgment status codes, leaving the buyer unsure whether changed quantities, dates, or backorders were actually committed.
