Just in time inventory is a practice that allows businesses to place orders of goods for immediate delivery. It conserves space, money, and time. It addresses the important question: What is just in time inventory? It is a clever approach to product handling and avoiding waste. Companies use it so they don’t have to hold excess inventory. It helps companies to become lean and efficient. This model can help with smooth operation and can save a lot of money if planned right. In this article we define what just in time inventory means, how it works, its management style, examples, and benefits.
What is Just in Time Inventory?
The just in time inventory system is a method of inventory control whereby a company receives goods only as they are needed in the production process. That means the company does not hold excess inventory. The system holds the supply chain short and live. Process helps optimize space and minimize storage costs.
How does it Works?
In these inventories, plans and purchase orders are based on in-the-moment demand. When an order comes in, the business gets in touch with the supplier. The vendor only brings in what’s needed for the moment. This helps keep inventory lean.
Key Elements
- They forecast demand accurately.
- It helps to have strong relationships with suppliers.
- Deliveries happen quickly.
- All stock is fresh, none of it is past its date.
Why It Needed?
In conventional inventory systems, more is stored than needed. This results in increased storage and handling expenses. Plus, items can become damaged or go missing over the years. These problems are avoided in a just in time inventory system. It works well for rapidly moving industries, such as tech, food and fashion.
Benefits of Just in Time Inventory
Just in time inventory are not just for large enterprises. Even small shops can use JIT.
