Back Order

Also known as: Backorder

A back order is an order for goods that cannot be fulfilled immediately because they are out of stock, to be delivered when stock is replenished.

When demand outstrips available stock, a supplier may accept the order and place it on back order rather than cancel it, committing to deliver once inventory returns. For buyers, back orders mean waiting — which can disrupt operations if the item is critical and the lead time is uncertain.

A high level of back orders signals demand-planning or supply problems and can point to inadequate safety stock. Buyers manage the risk by tracking supplier fill rates, holding buffer stock for critical items and, where possible, multi-sourcing to reduce reliance on a single stock position.
