METHODS AND SYSTEMS FOR UPDATING PERPETUAL INVENTORY AT RETAIL SALES FACILITIES

In some embodiments, methods and systems of updating perpetual inventory at a retail sales facility are described. After products are delivered to a retail sales facility, an electronic inventory management device receives electronic data indicating that a product has been delivered and calculates, based on at least one factor associated with the product, a delay period from a time of delivery of the product to the retail sales facility to a time for updating the perpetual inventory of products at the retail sales facility. After the calculated delay period elapses, the electronic inventory management device updates the perpetual inventory of the products at the retail sales facility in a product inventory database associated with the retail sales facility with information associated with the product delivered to the retail sales facility.
