Distributor Inventory Planning: Reorder Points and Safety Stock

For a medical equipment distributor, inventory is a balancing act. Too little stock means lost sales and an unhappy hospital; too much ties up cash in equipment that sits in a warehouse. The tools that solve this are the reorder point and the safety stock. Here is how to use them to plan a medical equipment inventory that works.

The two numbers that control inventory

A reorder point is the stock level at which you place a new order. When your inventory drops to that level, you reorder so you do not run out before the new stock arrives. A safety stock is the extra buffer you hold to cover a delay or a spike in demand. Together they set your minimum inventory level, and they keep you from both a stockout and a costly excess.

How to set a reorder point

The reorder point is the demand during the lead time plus the safety stock. If it takes, say, 30 days to get a reorder and you sell a set number each month, the reorder point is the amount you expect to sell in those 30 days, plus your buffer. The supplier’s lead time drives this, so a reliable lead time makes planning easier. See our medical equipment distributor guide for the sourcing side.

How to set a safety stock

The safety stock covers the uncertainty: a late shipment, a seasonal spike or a slower lead time than expected. A common method is to hold enough for a set number of days of demand beyond the reorder point. The more variable your demand and the less reliable the lead time, the more safety stock you need. For a mission-critical medical item, the safety stock should be generous, because a stockout means a hospital cannot provide care.

Match the plan to the product tier

Not every item needs the same plan. A high-value, slow-moving item, like a surgical light, should be planned to avoid a big capital tie-up, while a high-turnover item, like a consumable or a spare, should be stocked more generously to avoid a stockout. Tier your inventory by value and turnover, and set a plan for each tier. This prevents the two mistakes at once.

Use the supplier’s lead time

The supplier’s lead time is the biggest input to a reorder point. A supplier with a reliable, short lead time lets you hold less stock, which frees cash. This is why a factory like Sanyang, with a standard 3-7 day lead time on standard products and a long-term spare-parts plan, makes a distributor’s planning easier. A dependable lead time is worth more than a low price if it lets you carry less inventory. See our spare parts inventory planning kami.

Review and adjust

Inventory planning is not a one-time task. Demand changes, lead times shift and seasons pass, so review the reorder point and the safety stock regularly and adjust them. A plan that is never reviewed becomes stale. Quality management principles, such as those promoted by the American Society for Quality, underline that a controlled process is a reviewed process. Our distributor case study shows the plan in practice.

A reorder point and a safety stock are the two numbers that keep a medical distributor’s inventory healthy. Set the reorder point from the demand over the lead time, hold a safety stock for the uncertainty, and tier the plan by product value. Review it regularly, and you avoid both a stockout and an excess. Sanyang Medical supports distributors with a reliable supply of medical equipment.
