What is the difference between a stockout and a backorder?

• A. Stockout occurs when no inventory is available; a backorder occurs when demand cannot be fulfilled immediately but will be filled later.
• B. Stockout means demand is met later; backorder means no inventory.
• C. Stockout occurs due to supplier issues; backorder occurs due to internal delays.
• D. Stockout occurs with finished goods; backorder with raw materials.

Answer: (A)

Understanding inventory status at the moment of demand: whether stock is on hand to satisfy the order. A stockout happens when there is no inventory available to fulfill the order immediately. A backorder occurs when the demand can’t be filled right away but will be fulfilled later once more stock arrives or is produced. This distinction matters for planning and customer expectations: a stockout usually means lost sales or the need to offer substitutions, while a backorder keeps the sale but requires clear communication about delivery timelines and how the backlog will be cleared. The other descriptions mix up the timing, the type of inventory, or the cause, rather than focusing on whether fulfillment can happen now or must wait.
