Backorder
A backorder is an order, or part of an order, that cannot be filled now because the item is out of stock, but the buyer still wants it shipped when inventory returns. It is recorded against the original order and fulfilled later. High backorder rates signal demand outrunning supply or forecasting gaps.
How backorders are handled
The available quantity ships, the shortfall is flagged as backordered, and a second shipment follows when stock arrives. The order system tracks the open quantity so it is not lost or double-shipped. Buyers often set rules on whether to backorder or cancel the shortfall.
Backorders and order accuracy
A backorder is legitimate, but a short shipment that should have been flagged as a backorder and was not looks like an error and can trigger a chargeback. Capturing the backorder status in the acknowledgment and ASN keeps the buyer and supplier aligned.
