Inventory management has a huge impact on the profitability of an e-commerce business - especially when you operate a business with a fairly sizeable inventory. When inventory levels are too high, cash is tied and space is inefficiently utilized.

A common reason for inventory levels being too high or low is inaccurate counts. Here are tips for making sure your inventory accounting is accurate at all times.
