What is a good stock turn rate?

For example, if you have a high stock turn but also a low customer service level, it could mean that you’re not holding enough stock to cover your demand. In this case, it would be better to invest in more SKUs to bring your stock turn down and boost your customer service level.

One way your stock turnover can be increased is by adjusting your reorder points or reorder quantities.
