Many small to medium businesses that carry high inventory costs are seeking an inventory management solutions that can reduce inventory carrying costs: Just in time (JIT) is one of the systems that has a strong appeal to these companies.
Does the just-in-time method actually work for small and medium businesses? Sure, some businesses make it work, but inventory and supply chain experts caution against rigidly adopting an inventory system that doesn’t match the company’s business model.
The just-in-time inventory system was developed in Japan in the 1970s when Toyota, over the course of several years of trial and error, standardized the system at its automobile manufacturing plants. Toyota sought to reduce inventory levels to the absolute minimum by receiving items from suppliers just as the last of those items were being pulled from Toyota’s warehouse shelves.
Supply-management consultant Ian Johnson argues that few small and medium businesses have the purchasing power and strong economies of scale necessary to successfully adopt just-in-time inventory management: “Ultimately, large companies can make JIT work because they have guaranteed contractual supply agreements in place. Small businesses typically have infrequent demand patterns and low volumes and are almost never their suppliers’ number one priority. In essence, small businesses are typically at the end of the line in terms of priorities—regardless of what their suppliers say.”
Small and medium businesses have other challenges, Johnson notes, when trying to adopt just-in-time processes: Small businesses simply don’t have the constant and linear demand necessary to make lean-inventory methods work like they do for large companies: “Companies that are successful running this inventory management approach are required to ship product daily, weekly and monthly. In some cases such as Dell, they ship product on the hour. This is the essence of linear demand. It’s constant and almost never seems to end.”
JIT inventory management makes small businesses vulnerable to a supply shock. Sudden changes in supply or demand can prevent a small business from meeting customer demand. Moreover, JIT systems work on the assumption prices remain constant.
So, if just in time is off the table for most small and medium businesses, what are the options for a business looking to reduce the costs of retaining inventory and insuring its ability to avoid stockouts and missed sales opportunities?
Businesses shouldn’t emulate an inventory management system just because another business is running it or because a system has been valorized in the business media. “Focus on one simple rule to supply chain optimization,” Johnson advises. “Match your inventory strategies to your customers’ needs, your markets business cycles and your product’s sales cycles. If that means running Min-Max, or a demand-driven derivative, then so be it. Just don’t run something you can’t merely because someone else is.”
All inventory needs to be tracked. Small and medium businesses can make this simpler with the right inventory management system. The costs of holding inventory, shortages, and orders are balanced through continuous review. This allows you to establish par levels for a product and as inventory falls below a specific quantity, orders can be automatically initiated.
Regardless of the inventory management system your small or medium business uses, the right technology can help you cut inventory costs by eliminating errors and automating purchasing orders.
Software can create inventory profitability reports to show you which items are selling and profit margins. For manufacturers, software can help you create assemblies that define exactly how many parts, components, or materials are needed to complete a product.
Technology will increase productivity and efficiency for any small or medium business by automating purchase orders, which replenish inventory when it reaches a predetermined level.
Holding excess inventory increases overhead costs and reduces liquidity. Having insufficient inventory prevents you from satisfying customer needs. Inventory solutions offer easy, accurate means of closely tracking these factors as they fluctuate.
Businesses need to regularly audit their stock with some specific procedure, but the appropriate technique will vary from one organization to the next. Here are some general ways businesses can audit their stock:
The right inventory management tool is the one that best helps a business meet customer needs. Different businesses have different needs with respect to warehouse management, product management, order management, inventory management, and general inventory management. Having the appropriate tool can help integrate stock information into a more cohesive picture, make better projections about the future, and more easily manage the scale of a business.
