Reorder Point

Reorder points

Safety stock is the amount of inventory a business holds to mitigate the risk of shortages or stockouts. The safety stock calculation is the difference between the maximum daily sales/usage and lead time, and the average daily usage and lead time. The reorder point represents the inventory level at which it’s most efficient for you to submit an inventory order to your supplier. The safety stock level is the minimum number of units a company needs to have in stock to fill sales orders or meet production targets. Once inventory dips below the calculated reorder point, replenishment is triggered through a new purchase order. Inventory management software from Finale Inventory makes reordering your stock fast and stress-free.

The situation can be complicated if the same order can be passed to multiple suppliers delivering the same SKUs with different lead times (and typically different pricing as well). In such a situation, a backorder made to a local supplier can be delivered before an older backorder made to an distant supplier. Early works on the question date from the late 1970s, but for recent materials see Koenker, Roger (2005) Quantile Regression, Cambridge University Press. Working with dozens or hundreds of spreadsheets can be time-consuming and error-prone for growing retailers, manufacturers, or wholesalers. If your business falls into this category, consider the benefits of inventory management software.

What is the ideal reorder point?

Understanding how to manage your stock levels, calculate reorder points, and when to replenish your inventory ensures your business maintains a competitive edge. When your inventory reaches a reorder point, it’s time to replenish that stock. By reordering before you’ve run out of inventory, you ensure you don’t have a gap in the products and services you can offer customers. According to our example, we have a daily sales velocity of 5 chairs per day, a lead time of 35 days, and 15 chairs of safety stock. If you wait until you’ve run out of inventory to reorder, you’ll have a stockout until the shipment arrives and miss out on sales opportunities. Knowing how quickly your products sell and how long it takes for a new shipment to reach you can help you set reorder points and avoid stockouts.

  • Over time, the incidents account for a large portion of wasted budget.
  • Your lead time is the amount of time it takes a supplier to send the keyboards from the moment they receive a purchase order.
  • It connects to the database, fetches the data, processes it, and updates the reorder levels.
  • Reorder point (ROP) is a supply chain management technique that businesses can use to guide this delicate balancing act to improve inventory operations, avoid stockouts, and maintain ideal inventory levels.

Recalculate your ROP whenever you experience major changes to maintain optimal stock levels. When the reorder point is reached, a new order of product is necessary to avoid stockouts, depending on seasonality and forecast demand. Storing more inventory than what can be sold in a timely fashion is not a productive use of capital. Reorder points provide businesses with greater financial flexibility by allowing them to keep a minimum amount of inventory on hand without running out of products.

However, it takes one day to get approval for the order and another day for the manufacturer to process the order. Smaller businesses often sidestep using the formula and get by without a clear product ordering plan. But if you want to scale, you’ll find the process difficult without a means of identifying the right time to order. Suppose we have a supplier that has been delivering this item to us, on average, in 14 days. However, over the last year, there have been deliveries of this item that have taken as much as 25 days to reach us. In the scenario on the screen, this company starts with 10 weeks of inventory and as the weeks go by, the inventory is slowly depleted.

And let’s assume that the average daily use is 1.5 units, and the average lead time is 12 days. Average delivery lead time is the average amount of time it takes for a shipment to arrive from the time the order was placed. Average delivery lead time changes with fluctuations in seasonal demand, the quantity ordered, and distance from the up-chain supplier. For a reasonable measure, take an average of the past three months of POs for the SKU item you want to set a reorder point for. Average daily sales is the average number of units sold or used per day over a defined time period. A retailer would measure the average number of units sold, while a manufacturer would calculate the average number of components used per day.

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. Unlike spreadsheets, inFlow was designed specifically for working with inventory. The reorder point for replenishment of stock occurs when the level of inventory drops down to zero. In view of instantaneous replenishment of stock the level of inventory jumps to the original level from zero level. A reorder point is a fairly straightforward concept, but successful implementation requires paying attention to nuance and details about the business, suppliers and customers.

Minimize costs

In such cases, your reorder point can be calculated by multiplying your daily average sales by your lead time. Typically, when you don’t have safety stock, your reorder level and the frequency of your orders tend to be higher. But let’s say there were a couple of days in the three-month calculation period where you sold up to seven cards. Lead time demand refers to how long it typically takes your supplier to receive, process, fulfill and transport the order to your store. Calculate lead time by looking at previous sales records for the current month, season and year, and determine the average wait time in days.

Standard Deviation of Lead Time

Inventory levels below optimal are highlighted in red, indicating that you should create a new Purchase order or Manufacturing order.

In many cases, a broader view beyond an inconsistent set of numbers will get your product moving again.

Reorder points

Businesses with a limited number of products can start with excel spreadsheets and format cells to turn red when inventory levels reach the reorder point. Average delivery lead time is the average time it takes for a shipment to arrive from when the order was placed. The reorder point varies from product to product and is primarily influenced by two critical factors – daily sales velocity and lead time. Once you have your safety stock number, you can then plug it into the reorder point formula for insight in your reorder levels. If you sell 5 chairs each day, for example, your daily sales velocity is 5. So now you know the reorder point formula, but what about demand during lead time?

For consistency of the analysis, the input settings (reorder points, service levels and lead times) need to be extracted at the same time. Based on the conventions we follow in this sheet, this time can be either at the very end of Day 0 or just before the beginning of Day 1. Then, those settings are validated against sales data that happen afterward.

The formula allows businesses to have enough inventory to meet customer demand and ensure orders are received in a timely manner. It also helps businesses avoid having too much inventory on hand, which can result in extra storage costs that cut into profit margins. In the above graph, the maximum level is the sum of the safety stock and the order quantity, or 3400 bottles. Once the stock left in your inventory reaches the reorder level of 2400 bottles units, you should place a new purchase order with your vendor.

Whether you’ve just started a new business or sold products for years, anyone can benefit from using the reorder point formula. This post will show you what that is, why it’s useful, and which numbers you’ll need to generate a reorder point. ROP stands for reorder point, which tells a business when to place an order (where the “when” is given in terms of current inventory levels). EOQ stands for economic order quantity, which determines how much to buy when placing those orders. Reorder points come from a wide range of stock and purchase factors – think daily average sales. But there’s not a direct relationship in the formula to customer service and customer satisfaction.

Here are a few strategies that will help you turn theory into practice. All inventory control practices are designed to satisfy orders as quickly as possible. But it’s up to you to go above and beyond with additional service factors for total customer satisfaction. This includes following up on sales and sending Reorder points out customer surveys to enhance your fulfilment process. Using the variable from this section and the previous section, let’s put everything together from the original formula for our safety stock calculation. Returning to our example, let’s say it takes one week for a birthday card order to arrive.
