Knowing how to manage inventory levels, determine precise reorder points, and refill inventories will give your company a competitive advantage. 


Keep in mind that, although the terms of reorder point and safety stock are often used interchangeably, there is a clear difference that you should consider. 



Reorder Point


The reorder point (ROP) is the minimal number of units a company must have in stock to avoid stock-outs and assure order fulfillment. When inventory levels approach the reorder point, the replenishment procedure is triggered to restock that item. The primary objective of reorder point is to ensure that your company can maintain inventory at a level that can consistently meet consumer demand. 


The reorder point is generally based on prior sales to help you anticipate the item’s future sales. Reordering point strategies cannot fully prepare you for all sorts of challenges and delays that may arise in your inventory management. However, they can give you a dependable means to guarantee your warehouse remains supplied.


It is essential to calculate and consider every detail of the reorder point. This will help you avoid significant lag periods and reduce the possibility of back-ordered popular products.



Safety Stock


It is essentially an extra inventory that a firm keeps on hand to avoid running out of stock. Safety stock is crucial, especially if you’ve overestimated the reorder threshold or there is a supply chain failure. It will help you satisfy customer demand and deliver orders according to the deadlines, keeping your customers satisfied. 


Safety stocks are exceptionally efficient for items and products that are popular and demanded. Having an excess supply of the most popular things on hand in the warehouse will ensure that requests for such products are filled as soon as possible. On the other hand, it is also essential to keep balance. You should avoid over-purchasing products that are rather unpopular or a product that isn’t ready for market. It can result in unnecessary financial expenses on storage and marketing of excess units.



Critical factors essential for the reorder level


It is essential to understand that the reorder point varies for each product and is heavily impacted by two crucial factors: daily sales velocity and lead time.

Daily Sales Velocity


Daily sales velocity, or in other words, the average number of units sold each day, varies depending on what you sell. It is essential to understand that each item or product in your has a distinct sales velocity. You may have a product that constantly sells, necessitating you to supply it more frequently and in larger quantities than other goods. Moreover, specific goods may sell quicker during certain seasons, leading your sales velocity to increase momentarily. In order to determine a product’s reorder point effectively, you must first understand the abovementioned factors and how they may affect your sales velocity.



Lead Time


Another major factor for understanding reorder points is lead time. It is the length of time it takes for an ordered supply to arrive from your supplier. Supplier delays can cause issues with inventory management, resulting in a shortage of your goods. Delays can have drastic effects, especially when it comes to popular items. Not being able to deliver demanded products on time can have a negative influence on your company’s general image. It can also negatively affect customer reviews. Moreover, if the client service starts to deteriorate because of delays, your customer base might choose your competitors with more dependable and constant inventories.
