You can set a Reorder point for each product and material directly on the Stock screen.

If you keep too much stock, there may be additional costs related to renting additional warehouse space, paying salaries to those handling the stock, risk of stock expiring or becoming outdated, and more. Every manufacturer needs to find a good balance between having enough stock to weather the storm but not too much that it breaks the bank. Each point-of-sale, or POS, system uses reorder points in a different way. For example, some will calculate reorder points for you automatically, while others use the reorder points you enter to help automate the reordering process.

How to Calculate Safety Stock

In the early days of your business, you probably used your instincts. Once every two weeks, you’d eyeball your stock, guess what you’d run out of in the next few days, and put in an order. The inventory quantity to be compared to the reorder point is usually the sum of the stock on hand plus the stock on order. Indeed, when making an order, one has to anticipate the stock already on its way. Reorder points are used to ensure you always have sufficient stock to protect the business against spikes in demand or shortages in supply. While implementing a reorder point strategy may not address the whole puzzle, it provides a more exact basis for your stock replenishment schedule.

Katana automatically flags the product and material variants that have dipped below their reorder point, allowing you to identify the areas that require action. When calculating reorder point levels, pay attention to changes in the underlying metrics. You get a perfect balance, safe in knowing you can deal with anything, and keep going. Read on to find out how to use a reorder point formula to set your reorder point. If you don’t, your safety stock will eventually deplete to nothing, and since more orders cost more money, you should try to avoid this. So, producing too many finished goods could end up evaporating your profit margin.

The process might appear a bit puzzling because we apply the term accuracy in a context where no forecasts may exist (if the company does not have any forecasting process in place for example). The trick is that target inventory levels by themselves represent implicit quantile demand forecasts. The pinball loss function let you evaluate the quality of those implicit forecasts.

Optimal inventory levels

You should place a new order with Supplier B once your stock hits 1,451 workout shirt units. She is also the CEO of BLOOM Digital Marketing, a creative marketing agency that helps the hospitality and tourism industries reach millennials online. Use POS data and empirical evidence to determine when to reevaluate your ROP. A grocery store, for example, would likely have higher reorder points for quick-selling produce than a furniture store would for slow-selling mattresses.

Reorder points

To accurately calculate a product’s reorder point, it’s important to understand these factors and how they might impact your sales velocity. It’s the number of units of a particular item that you hold in to avoid a stockout (completely running out of the product). Lead time is how long it takes for you to get the inventory from your suppliers when you order it. The longer it takes for you to receive new stock, the higher the reorder point would be and thus the longer your lead time would be. Reorder point formula is the mathematical equation used by businesses to calculate the minimum amount of inventory needed to order more products, to avoid running out of inventory.

You and staff will be better prepared for in-demand events, like sales and promotions, and have an exact inventory count to fulfill bulk orders if necessary. It’s also easier to troubleshoot potential problems, like late shipment arrivals, or notice when items go missing from the sales floor. When you pair this information with top-notch customer service, you can set yourself apart from the competition. If you operate multiple different in-person and e-commerce sales channels, work with dozens of separate vendors, stock thousands of inventory pieces or oversee numerous warehouses, your plate is full enough. Automated reordering based on your established reorder level and max inventory management system can help you stay organized and eliminate the more repetitive nature of your work. It also means you’re less likely to oversee important reorder dates and remain productive without costly pauses or stockouts.

Try Katana for free with a 14-day trial and see for yourself why thousands of manufacturers use it daily to manage their business. For example, Katana lets you set reorder points and highlights when you need to order more materials to keep ideal inventory levels. If reorder points don’t automatically trigger a purchase order, warehouses can no longer take advantage of this cost-saving strategy since the warehouse closest to a customer may be out of stock. The service level represents the cost of missing out on a sale versus the cost of purchasing more inventory.

However, using a very high service level in the formula does not yield an equivalent service level in practice either. In short, you may enter 99.9% in your software, but in reality, your observed service level will not raise above 98%. This situation is caused by the assumption that the demand is normally distributed. This assumption, used in the classical safety stock formula, is incorrect and leads to a false sense of security. Quantiles, however, respond much more aggressively to high service levels (i.e. bigger stocks). Yet, quantiles are merely reflecting the reality in a more accurate manner.

Neglected inventory management leads to a decrease in customer loyalty, in addition to lost sales. Negative reviews can quickly erode any positive online presence you’ve built. You source the shirt from Supplier B, who has a typical lead time of 7 days.

If the supplier delivers on-time, i.e. in 10 weeks, that means the new inventory should arrive just as we are reaching an inventory level of 4 weeks worth of stock. Additionally, let’s say that we typically use about 10 of these items per day in our production line, but we also have days where we’ve used as many as 14 in a day. Putting these 4 values into the Safety Stock formula, we get a value of 210 for our safety stock level. Therefore, a good reorder point also needs to consider the number of ordered items left in your warehouse by the time the materials arrive.

Accuracy of reorder points through the pinball loss function

If your lead times are long and can be expressed in weeks rather than days, then, yes, you can use historical data aggregated in weeks, the approximation should be good. However, if your lead times are shorter on average than 3 weeks, then the discrepancy introduced by the weekly rounding can be very significant. Reorder points In those situations, you really should consider daily aggregated data. Daily data might complicate a bit the data handling within the Excel sheet, because of data verbosity. However, in practice, the pinball loss is not intended to be computed within an Excel sheet except for Proof-of-Concept purposes.

In your Retail account, you can maintain consistent stock levels and avoid over ordering by using reorder points and desired inventory levels. Average daily sales is the average number of units sold or used per day over a defined period. Inventory carrying costs typically account for 15-30% of total inventory costs. To protect profits, businesses can use the most optimal reorder levels to keep storage and warehousing costs low. However, while deciding when to make or purchase more items, lead times need to be taken into account. Reorder points account for lead times and are typically a little higher than the Safety Stock level.

For Supplier B, your reorder point will be higher because you need to account for more days of stock between your order and when new stock arrives. Going back to our athletic apparel example, let’s assume your most popular product is a unisex workout shirt. For example, you could keep 15 extra chairs, 3 days’ worth of products, in stock in case the shipment arrives late. InFlow Cloud has a Recommended Reorder Point report that examines your sales data and recommends reorder points for your products. It also factors in goods in transit (GIT), which are products that have been ordered from a vendor but haven’t been received yet. If you’re a spreadsheet user, you can use conditional formatting for the quantity value of specific cells.

The longest time the supplier would take to deliver this component is 15 days. And let’s assume that the average daily use is 1.5 units and the average lead time is 12 days. To accurately calculate reorder points, you’ll need strong sales volume records and trends over a certain period. As you build this body of data, you can improve forecasting to meet customer demand better. Calculating your inventory fill rate will also help you forecast the rate at which your business can fulfill orders to meet supply and demand. There are several benefits to using the reorder point formula, such as saving on inventory costs and improving customer satisfaction.

The standard deviation helps you express how reliable your suppliers actually are, so you can better calculate your buffer stock. To find your standard deviation of lead time, you need access to historical data. The more data the better since you want your standard deviation of lead time to be an accurate reflection of reality. For most companies, service levels float somewhere between 90 and 100 percent. For instance, if your service level is 92 percent, you’re saying you want to fulfill orders for this product at least 92 percent of the time. When it comes to preventing stockouts, safety stock is the last line of defense.

The minimum level, which is 1400 bottles, will help you fulfill your orders until your ordered stock reaches the warehouse. Once the new order is received in your warehouse, the stock level returns to the maximum level of 3400 bottles units. If you’re a business owner, knowing when to order more stock is important.

Which POS systems allow you to set reorder points for inventory?

In this scenario, the 14 weeks of inventory level is our reorder point. This means that when we reach the point of having 14 weeks of inventory in-house, we place an order with the supplier. Our example company likes to order 13 weeks of inventory at a time because of certain production considerations.

There’s no doubt that the best way to track your inventory accurately is through an automated system using inventory management software. It connects to the database, fetches the data, processes it, and updates the reorder levels. The system can also send out notifications and even save the results to specific folders, making it easy for stakeholders to access and act on the information. Accurate reorder points play a crucial role in your daily operations. When implemented correctly, you can leverage them to make smarter financial decisions and build stronger relationships with your customers.
