>For internal tools, it seems to be fine to have more approximate data It's moreso that completely accurate inventory takes an incredible amount of resources and man power to maintain, and you get diminishing returns the closer you try to get to 100%. Retail is a big industry and there are many very talented people working on this problem. Retail orders are done automatically based on inventory, and if the numbers are off, either too little will be ordered (out of stock = lost profit) or too much (backstock = man hours spent dealing with it). So there's a clear profit motive to have tight inventory. This is a much bigger deal to these stores than whether the numbers are internal or customer facing.
