Why should your business know your reorder points?

The optimal inventory level is the balanced level between demand and supply that minimizes the total cost of inventory including purchase, warehouse space rents, carrying, operational costs. Businesses can manage their cash flow better by preventing stockouts and overstocking by balancing inventory levels using reorder points. If you sell 5 chairs each day, for example, your daily sales velocity is 5. Reorder point is the lowest inventory level at which new items must be purchased to avoid stockouts.

So, a company must have a good balance between safety stock and overstock. Now we use historical data to determine the standard deviation of lead time. Safety stock is the number of materials or products stocked in the warehouse during unexpected emergencies. The reorder point is the quantity of units in inventory at which time an order should be placed to purchase additional units. You require about 100 units of safety stock in your inventory to guard against the unexpected.

  • Analyzing your reorder point in your inventory management process can help you align with the sales trends and maintain the inventory needed for desired customer experience.
  • Therefore, a reorder point can be used with or without a specific supply planning method.
  • Now all you need to do is subtract the maximum value from the average value.
  • Your maximum daily orders are the highest number of a certain item you can reasonably expect to sell in a day.
  • In other words, it’s a minimum inventory threshold that triggers a new order of additional inventory.

It also depends on several other factors, such as discounts, the item’s delivery time, safety stock, and so on. Some companies also include safety stock in their calculations to ensure they never run out of product. There are many benefits to using this system, including increased efficiency and reduced costs for over-ordering or under-ordering products. It’s not enough to know the average demand for a product, as that demand can increase suddenly or problems with a supplier can prevent you from restocking inventory as quickly as you expected. Safety stock, as the name suggests, is the extra “just in case” inventory you keep on hand to anticipate variability in demand or supply.

The reorder point tells you when to reorder inventory, so that you won’t run out of stock. It usually triggers the purchase of a predetermined amount of replenishment inventory. If the purchasing process and supplier fulfillment work as planned, the reorder point should result in the replenishment inventory arriving just as the last of the on-hand inventory is used up. The result is no interruption in production and fulfillment activities, while minimizing the total amount of inventory on hand. The Economic Order Quantity(EOQ) is the number of items that a business should add to inventory with each order to minimize inventory carrying costs. While ROP determines the lowest stock level, EOQ is used to determine the size of the order.
