4 Reasons Why Retailers Love Just In Time Inventory Systems

Overall, inventory management is an excellent strategy for any business that sells physical goods. Therefore, just in time saves you a lot of costs which would otherwise be tied up as inventory holding cost. At the same time just in time should be executed carefully so that your business does not face loss in times of unpredictable events. JIT inventory management relies heavily on precise forecasting and strong relationships with key suppliers. When something goes wrong with either of those, that’s a problem because there are no backup options in place.

This method is also calleda pull inventory system because manufacturers and distributors wait for customer demand to “pull” inventory through the supply chain. They make new purchases just days before they’re needed for resale or distribution, meaning inventory spends very little time in storage. It comes with the inherent risk of stockouts or delays because a supplier lead time delay can result in inventory arriving late. If one part of your supply chain goes down, it could potentially disrupt your entire production line. By refusing to carry safety stock as a contingency, you’re placing a lot of faith on the reliability of your manufacturers, shippers, and fulfillers. This doesn’t necessarily make JIT any better or worse than other inventory management strategies, but it does mean that you have to be careful in how you implement JIT.

MRP thus plays the role of planning adviser to the cell, setting the budget level in terms of the number of cards but not specifying the “expenditure” or release of the cards. The simple fact is that there is no need to choose between push or pull. These methods are not mutually exclusive, and each has its pros and cons. The best solution is often a hybrid that uses the strengths of both approaches. Since the system is reactive, changes in demand level percolate slowly from stage to stage. Even if it is perfectly obvious that demand is rising, there is no standard way to prepare for the situation.

In this common situation, push and pull systems can simply be juxtaposed—MRP II to ensure parts availability based on end-item schedules and kanban for actual subassembly and assembly releases. MRP can be run only as frequently as necessary for parts purchasing and planning. Since the floor schedules can change quickly, the MRP database will always be playing catch-up with actual part withdrawals.

Steps in Cycle of Continuous Improvement for JIT Inventory

It should be noted that a JIT inventory management system is not easy to implement and carries the potential risk of production shutdown leading to losses. However, if executed meticulously, the benefits that can be realized outweighs the impending risks involved. The JIT inventory model exposes enterprises to the potential of spikes in raw material costs which in turn lead to a surge in profit as the final products are usually preordered. This system typically relies on long-standing contracts within the local supply chain to deliver the different parts it needs to assemble an automobile.


In order to optimize time, which is your main resource of action, you must be able to incorporate certain guidelines and procedures for your employees. According to an article by the QuickBooks Canada Team, “an employee must know exactly what to do prior to the receipt of an order. Once an order has been placed, it is the responsibility of the well-trained employees to know exactly what needs to be done”. Our mission is to empower readers with the most factual and reliable financial information possible to help them make informed decisions for their individual needs.

If there are points at which small inventories are accumulated for quality control or accounting purposes, they can be replenished in a pull manner. Indeed, MRP has become so much the standard for materials management that it has led to the professionalization of the task, as exemplified by the American Production and Inventory Control Society. At the same time, owing to the heavy computer demands of MRP, systems managers and MIS departments have taken over a good deal of manufacturing management. It underscores the importance of lead-time management in all aspects of manufacturing.

A firm also no longer needs to spend large amounts of money on raw materials for production, because it only orders exactly what it needs, which frees up cash flow for other uses. The just in time inventory control model allows a business to quickly respond to shifts in customer needs and reduces the number of unsold or outdated products. This model is best used for businesses that have shorter demand spikes.

Let’s delve a little deeper into the important factors that helped these companies effectively implement a just-in-time inventory system and how they reaped the benefits of their implementation.

What’s The Reasoning Behind Using JIT Inventory ?

This can be a challenge, particularly for businesses expanding their operations or adding new products. JIT offers advantages such as allowing manufacturers to keep production runs short and move on to new products quickly and easily if needed. Companies using JIT no longer need to maintain a huge expanse of warehouse space to store inventory.

To ensure that things keep flowing, they keep small quantities of raw materials at every production station. The benefits of following a JIT inventory management are numerous, considering that storing and waiting for materials can increase costs. However, a poor handling of such strategy may result in potential risks in the supply chain. For example, if a certain supplier fails to deliver the goods on time, it may cause a disruption in the entire production process.

Verticals that Use JIT Inventory Management

Maintain healthy cashflow by ordering small stocks only when necessary. JIT, on the other hand, can be implemented on its own or adopted as one of the several steps in lean manufacturing. Many reasons have been advanced as to the actual motivation behind the development and application of JIT by Toyota and generally many Japanese manufacturing firms. There are warehousing and storage fees and the opportunity cost of not investing that money elsewhere. Thousands of manufacturers use Katana to get a live look at their just-in-time inventory.


You can assess if just in time inventory management is right for your business by considering the benefits and costs and whether it aligns with your business goals. Overall, just in time inventory management can be a very effective way to manage inventory and keep costs down. However, some potential drawbacks should be considered before implementing them.

In contrast, JIT people seem especially drawn to such computerless, “pull” techniques as kanban, the system used extensively in Japan’s auto and electronics industries. For JIT, presumably, human pull is good, computer push is bad. Just in time, inventory management can be a very effective way to manage inventory and keep costs down. However, some potential drawbacks to using this type of inventory management should be considered before implementing it. Despite the benefits of JIT inventory systems, there are also a few challenges that should be considered.

What is Just in Time Inventory?

Example of JIT 13 Famous for its JIT inventory system, Toyota Motor Corporation orders parts only when it receives new car orders. Although the company installed this method in the 1970s, it took 20 years to perfect it. Because Aisin is the sole supplier of this part, its weeks-long shutdown caused Toyota to halt production for several days. This caused a ripple effect, where other Toyota parts suppliers likewise had to temporarily shut down because the automaker had no need for their parts during that time period. Consequently, this fire cost Toyota 160 billion yen in revenue. A JIT inventory management system means you’re not putting down large amounts of cash on stock that you may or may not need down the line.

These unsalable products turn into inventory dead stock, which increases waste and consumes inventory space. In a just-in-time system you order only what you need, so there’s no risk of accumulating unusable inventory. For example, a single supplier that can’t deliver for any period of time can disrupt the entire supply chain and halt your operations. In addition, companies practicing strict JIT inventory management probably won’t have extra stock to satisfy unexpected orders. The just-in-time, or JIT, inventory system is a strategy in which orders of raw materials for manufacturing are aligned closely with production schedules.

  • Here is a closer look at these two types of inventory management.
  • If a raw-materials supplier has a breakdown and cannot deliver the goods promptly, this could conceivably stall the entire production line.
  • Establishing a strong relationship with reliable and efficient suppliers with the ability to source and deliver small batches of raw materials on time.

You can also receive and store deliveries in the smallest possible quantities, virtually eliminating excess raw material inventories. Local sourcing ensures that your suppliers are located near your company’s production facilities, enabling timely deliveries and reducing the need for safety stock. Inventory management ensures that the right amount of supply is available to meet customer demand. With the right inventory management systems and processes, the business can accurately predict and meet customer demand. The goal is to generate the maximum profits from minimum investment in inventory without impacting the customer experience. Inventory management can help avoid problems, such as stock-outs or overstocking.

Just in Time Inventory Management: A Brief Overview

SAP S/4HANA is an integrated ERP solution that has embedded analytics, industry best practices, artificial intelligence , robotic process automation capabilities and much more. It offers financial management, asset management, supply chain management, production planning, contract management and procurement capabilities. Katana provides a wide range of features that are important for the successful implementation of a JIT inventory management system in an organization. With production based in the cloud, this solution is ideal for handling inventory management in small and mid-sized manufacturing businesses. This watchmaker was the pioneer in adopting lean manufacturing strategies within the industry.

In a JIT system, there’s little to no room for errors like missed shipping windows and slower-than-usual production. Just-in-time parts inventory management is a management system that orders parts and products from suppliers only as required to meet the immediate customer demand. These items arrive from suppliers “just in time” to be immediately processed and shipped to fulfill customer orders. If you chose to work with this type of inventory management, and when it is working perfectly, you would have very little or no inventory on hand.

  • Less capital tied up with carrying inventory allowed these businesses to be more flexible.
  • A JIT strategy can not only lower your inventory storage expenses but also allow you to spend less at a time on your inventory—freeing up valuable capital to spend on other business expenses.
  • There are more advantages than disadvantages to practicing JIT if you have a proven, reliable supply chain and accurate demand planning.
  • Many of the disadvantages of just-in-time inventory management can be tempered with finesse and careful planning.

For a continuous-flow process, ongoing materials planning is not essential and JIT supply techniques work well. Order releases do not change from week to week, so a rate-based approach can be used. At the shop floor level, JIT materials-flow discipline combined with pull release—kanban, for example—is effective. JIT inventory systems work by closely linking production with demand. In a JIT system, inventory is only ordered and replenished as needed to meet customer demand. This means that there is no inventory on hand that is not needed, which reduces waste and frees up storage space.

It is often used by the foodservice industry, technology manufacturers, and book publishing. These industries need to make product quickly to keep up with demand and avoid excess inventory when that demand falls. JIT, or just in time, is an inventory model where the raw materials you use or products you sell are delivered to your warehouse only as you need them. This involves staying in constant contact with your suppliers to ensure goods arrive at the optimal time. Many manufacturers choose this model to streamline their processes and save valuable resources. Let’s say you’re running a manufacturing business, and you’ve currently got so much raw material on hand that it’s taking up space on your shop floor and slowing down the production process.

Defective products result in wasted time, materials and effort and can impact the company’s reputation. With a smaller warehouse, you’ll save time managing inventory. You’ll also reduce movement waste among warehouse staff who do not have to travel long distances to collect, count or move inventory. Saving space and movement can also improve worker satisfaction and reduce the chances of muscle strains and other injuries.
