Open stock
The term "open stock" generally refers to items ordered by customers but not yet available in the warehouse. Like other types of stock, such as safety stock or reorder points, open stock is considered a business component. This refers to a certain number of units of an item that are not yet available in the warehouse or not in sufficient quantities - in relation to the order backlog.
With the help of IT systems, this can be indicated e.g. by means of availability displays in online stores. Estimated delivery times can also be specified based on empirical values.
Unlike safety stock, which is particularly important in the event of bottlenecks or special order peaks, open stock tends to indicate that there may be supply chain problems or that B or C goods are only held in stock in marginal quantities.
