Inventory software programs now on the market let you track usage, monitor changes in unit dollar costs, calculate when you need to reorder, and analyze inventory levels on an item-by-item basis. You can even control inventory right at the cash register with point-of-sale (POS) software systems. POS software records each sale when it happens, so your inventory records are always up-to-date. Better still, you get much more information about the sale than you could gather with a manual system. By running reports based on this information, you can make better decisions about ordering and merchandising.d
