Most common alongside 850

The 850 is the electronic purchase order a buyer sends to formally request goods or services, carrying items, quantities, prices, ship-to locations, and requested dates. It initiates the order-to-cash cycle and is the reference document that the acknowledgment (855), ship notice (856), and invoice (810) must reconcile against. Trading partners require it because a machine-readable PO removes manual re-keying and the wrong-item, wrong-quantity errors that come with it. Sent by the buyer (retailer, distributor, or manufacturer procurement) to the supplier or vendor fulfilling the order.

When it fires: A buyer's procurement or replenishment system releases an approved order for goods to a specific supplier.

Common 850 rejection causes
  • Ship-to addresses or location codes that do not exist in the seller's system, causing the order to fail validation or ship to the wrong warehouse.
  • Item identifiers referencing discontinued SKUs or UPCs that do not match the seller's catalog, forcing manual intervention.
  • PO line prices that do not match the agreed contract price in the seller's system, triggering business-level rejection on the 855.
  • Missing or malformed mandatory segments or data elements, rejected on receipt via the 997, and duplicate PO numbers that confuse order processing.
