When it comes to back-room and sales floor inventory, too much is simply too much.
Inventory glut can be a big problem for convenience retailers. Too much inventory means too many damaged products, high levels of shrink, and high amounts of labor devoted to maintaining all that stuff. There's a cost of holding that inventory, and the retailer could use that money for something else.
There is a need for a better system for counting, and more importantly, ordering products.
