backordered refers to items that are temporarily out of stock but are expected to be restocked and shipped at a later date. In e-commerce, backorders occur when demand exceeds supply, and a product is unavailable for immediate shipment. While waiting for the item to be restocked, customers are typically notified of the delay, and they may have the option to cancel or change their order. Businesses often offer backordering as a way to prevent lost sales and ensure that customers can still purchase popular items.
