Why is Inventory Control ImportantWhy is Inventory Control Important? Inventory is a significant asset and for many
companies the largest asset. Inventory is central to the main activity of
merchandising and manufacturing companies. Mistakes in determining inventory cost can
cause critical errors in financial statements. Inventory must be protected from external
risks ( such as fire and theft) and internal fraud by employees.
