Demand may be seasonal or unpredictable
Need to manage working capital
Holding stocks ties up cash in working capital
There is an opportunity cost associated with stockholding
Risk of stock losing
The longer stocks are held, the greater the risk that they cannot be used or sold
What are costs of holding stocks?
Cost of storage: More stocks require large storage space and possibly extra employees and equipment to control and handle them
Interest costs: Holding stocks means tying up capital (cash) on which the business may be paying interest
Obsolescence risk: The longer stocks are held, the greater the risk that they will become obsolete ( not capable of being sold)
Stock out costs: A stock out happens if a business runs out of stock. This can result in:
Lost sales and customer goodwill
Cost of production stoppages or delays
Extra costs of urgent, replacement orders
