Lead Time is the time interval between placed order and actual delivery or received an order. Lead time is directly related to either a purchase order or a production order which is issued to the company, manufacturing, or shop. 

The Lead time is useful in such a kind of scenario If a supplier (an external firm or an internal department or plant) cannot supply the required goods on demand, then the client company has to keep the Products in Inventory always, as longer lead time then a large number of Products in the company warehouse inventory has to be in stock.

In Some of the Manufacturing vertical in the automobile just in time manufacturing company matters with a lead time and those have an extremely low level of Inventory or some of the companies take delivery of some goods as many as 10 times per day. For example, like to manufacture a Steel Mills, it may take a 4 month lead time. That is a user of the company for Steel Mill Product must place an order at least 4 months in advance to fulfill the requirements.

Purchase Lead Time

Purchase is the process of buying material or product from a vendor. As we are discussing purchase lead time in this blog post we can also bifurcate the customer lead time. 

In Odoo we can control the Purchase and related operations, there is an adoptive option called Purchase lead time.

We can define the purchase lead time while PO (Purchase Order) is created and set the delivery time of the Buyer Product.

For customer satisfaction, we can consider a lead time a signified element even though a purchased lead-time is different from customer lead time or both are interlinked to each other. If a buyer is aware of the purchase lead time so he can set an accurate lead time. If any variation in the purchase lead time will affect the customer lead time directly. It can also cause customer dissatisfaction. The delay will also affect the supply chain.

Why is Purchase Lead time Management Important?

Purchase lead time is a key factor in managing all other operations related to the business. If we can calculate purchase order lead time efficiently, we will be able to plan to manufacture any product using the purchased material or the sale of the purchased product efficiently. 

This operation can be explained here with the help of an example. Suppose we have placed an order for a customizable desk on April 2. The lead time, here, is 10 days. Then the product will be arriving in our inventory on April 12. 

Once we can calculate this lead time, we can plan our manufacturing efficiency and manage the product delivery date to our customers more accurately. Suppose, a furniture manufacturing unit has placed an order on April 1 for wooden panels to manufacture shelves. The lead time he gets is 10 days. Then he can calculate the product manufacturing schedule, and location of his customer and find out the total number of days that will be required for product delivery. This will surely help us to ensure customer satisfaction as the customer will be getting the product within the promised date.
