what is a back order

what is a back order is a common logistics term describing a situation where a customer orders an item that is temporarily out of stock. The order is accepted and fulfilled once inventory is replenished. Backordering helps maintain sales continuity but requires accurate inventory forecasting. Fulfillment providers managing backorders must coordinate with suppliers and keep customers updated on expected timelines. Efficient backorder handling minimizes cancellations and preserves long-term customer trust.
