What happens when products run out? In a store, the product is simply no longer displayed. On the internet, customers not only continue to see products that are no longer in stock but they are likely to pay for them in advance and expect immediate delivery! Some products have longer lead times than others or perhaps some are kept in stock in limited numbers.

Inventory Management tools are helpful in managing orders and in tracking what is in stock and when additional purchases should be made (based upon statistical purchasing patterns).
