Storage and inventory control processes include the activities related to holding material and the processes of counting and transacting the material as it moved through the warehouse. The layout of a warehouse that supports an adjoining manufacturing facility will have different requirements than a facility supporting product distribution to stores or a facility that supports end-user fulfillment.
Best-practice companies have designed storage systems to meet the needs of the current and planned mix of storage types. By optimizing the storage locations and layouts to fit product without the need to restack it once received.
The WMS will track storage location and properly assign product to the best storage location. As a result, best-practice companies have excellent cube-fill rates. In addition, to optimize the cubic fill of storage locations, best practice is to minimize travel time. If a product is in high demand it should be placed closer to its next point of use.

The difficulty of retrieval should also be considered in travel time. Higher-demand product should be placed on the most easily accessed storage space, typically floor level for racking and between waist and shoulder level in pick racks. Most companies put a lot of effort into the initial layout of the warehouse.
