Excess stock is part of running any business that carries inventory. Demands can change quickly, bulk pricing is tempting, supplier minimums can be tricky and there is room for human error when
How to identify excess stock? And what you should do with it?
First consider non-stocked items. Any item that is not stocked is in excess when it sits in your inventory (minus backorders). These items are typically easy to identify since they should not be in your inventory at all.
Excess inventory gets a little trickier when looking at stocked items. With these items, you do not want your stock exceeding the maximum stock level. Your maximum stock level is the safety stock plus the replenishment cycle stock. Based on the assumptions that a) your forecasts are precise, b) the lead time for this item is accurate and c) the
Before deciding to dispose of excess inventory, evaluate the excess in days of supply. If the days of supply falls within an acceptable range of excess, e.g., 30 days, allow sales to bring inventory in line with maximum stock level. It is almost impossible to maintain perfect inventory levels. Give your teams guidelines for deciding when extraordinary measures are taken. Establishing an acceptable range of excess inventory, expressed in days of supply, provides leniency before efforts are expended on disposing of inventory.
One important consideration is the impact of lead time in the replenishment cycle. For example, assume an item in my inventory is over your maximum stock level by 1,000 units and that you have no purchase orders in your pipeline. If you get rid of those 1,000 units and your customer places an order, that order would arrive one lead time later. Therefore, a known short lead time would not threaten your customer fill rate or service level, but a long lead time might.

Excess stock is inevitable. Improving the processes around excess stock involve both people and tools. Create a dedicated team to monitor, manage, and dispose of excess inventory. A formal team will give the time and attention needed to prevent excessive stock and provide constant steps toward improvement. You will also want to consistently review purchasing lead times, minimums, and multiples your top suppliers.
