Gartner defines store inventory management (SIM) as the efficient and effective management of stock across all in-store processes, down to the granularity of SKU/item level, in a retail store. SIM is done on the basis of the quantity of stock, as well as its value. Retailers are now using store inventory to support online order fulfillment, and a SIM application must be capable of enabling store associates to easily manage daily stock operations across a number of key functional processes within the store. The application must also be an integral part of the retailer’s overall enterprise inventory management for unified commerce execution.
