What does "backorder" mean in logistics?

A backorder refers to an order for a product that cannot be filled at the current time due to lack of inventory. This situation arises when demand exceeds supply, and the item is temporarily out of stock. When a product is on backorder, the customer agrees to wait until the product is available again, at which point the order will be fulfilled and shipped. This is a common occurrence in logistics and supply chain management, especially for high-demand items or during supply chain disruptions.

The term encapsulates the fact that while the item is not available immediately, there is an expectation that the inventory will be replenished, allowing the order to be completed in the future. This understanding is crucial for managing customer relationships and expectations, as it influences how logistics operations prioritize and communicate about pending orders.
