What is the EDI 855?
The EDI 855 acknowledges a received 850. The supplier uses it to confirm the order, accept or reject line items, note backorders, or propose changes (price, quantity, dates). It gives the buyer early visibility into whether the order will be filled as requested.
How EndlessEDI handles the 855
Endless can generate 855s automatically from order status, flagging exceptions before they become chargebacks.
