Carrying obsolete parts in the parts department can quietly eat away at profits and easily balloon out of control over time. Obsolete parts that sit on the shelves can be a problem when trying to control cash flow since you essentially have cash tied up in inventory that does nothing but takes up space.
Right now, the average parts manager has an obsolescence rate of 30%. No matter how well trained a parts manager is, obsolescence will happen. However, you can make moves to keep it under control, with an ideal goal of less than 5%.
The best way to get rid of obsolete inventory and keep your numbers low is to prevent it from happening in the first place.
