What is Lead Time?

Lead time refers to the duration from when a customer initiates an order until the moment it is dispatched and ultimately reaches the customer’s destination.

To be more precise, lead time includes the time allocated for the processing and management of goods, all the way through to their delivery to the customer’s location.

In the following section, we will delve into various lead time types and their significance, providing you with a more comprehensive comprehension of the concept.


Types of Lead Time in Shipping

To help better understand what lead time is, it is important to know that there are different types of it. Here are the different categories:

1. Customer Lead Time

It pertains to the duration a company requires from the receipt of an order confirmation to its complete fulfillment.

2. Material Lead Time

This category is directed at both the company and the supplier. It encompasses the duration required to initiate an order for necessary supplies and the time it takes for those supplies to be delivered.

3. Production or Manufacturing Lead Time

This denotes the timeframe during which a company manufactures and delivers products using the raw materials that are at its disposal.

4. Cumulative Lead Time

This represents a blend of the previously mentioned types. The total delivery time encompasses the entire duration that a company requires, starting from the receipt of an order confirmation to the delivery of the product to the customer.

How to Calculate Lead Time

Understanding how to compute the shipping lead time is both straightforward and crucial, particularly in the realm of project management.

To begin, we’ll introduce the key terms involved in the calculation, enabling you to effectively oversee delivery schedules.

1. Supply Delay: This denotes the duration it takes for a supplier to meet a customer’s order once the order has been placed.

2. Reordering Delay: This signifies the time interval between the fulfillment of one order and the placement of the subsequent order.

Now, armed with these definitions, we can proceed to compute the shipping delivery time. Below, you’ll find the lead time formula that provides a comprehensive understanding of the entire concept of lead time.

Lead time formula (LT) = Order Delivery Date  – Order Request Date

Nonetheless, the concept shifts when we consider inventory management.

In the realm of inventory management, lead time encompasses the duration needed to ready an item for shipment, transport it, initiate an order for a replacement item, and subsequently incorporate the new item into the inventory.

This calculation also accommodates the reordering delay.

Consequently, within the scope of inventory management, the lead time formula is as follows:

Lead time formula (LT) = Supply Delay (SD) + Reordering Delay (RD)

How Do You Reduce Shipping Lead Time?

Customers have high expectations for quick processing and shipping when they shop online. But how can online merchants meet these expectations? In this article, we will provide tips to help you shorten the lead time for shipping in your eCommerce business.

1. Consider Dropshipping

Dropshipping is a strategy that allows products to be shipped directly from the manufacturer to the retailer or customer. By adopting drop shipping, merchants can free up more time to concentrate on marketing and lead generation.

This streamlined order fulfillment process often leads to faster shipping times.

2. Use a Reliable Shipping Platform

No matter how diligently you manage and optimize your estimated delivery times, the choice of shipping platform plays a critical role. Opting for a dependable shipping platform ensures that your goods are delivered punctually and reliably.

3. Simplify the Supply Chain

Delays in delivery often occur because supplies are not available when needed. Merchants sometimes source products from multiple suppliers, making it challenging to keep track of shipments.

To address this issue, consider simplifying your supply chain. You can achieve this by consolidating your supply vendors, making it easier to monitor shipments efficiently.

Choose suppliers with efficient operational processes to save time and enhance your supply chain management.

By implementing these strategies, you can work towards meeting customer expectations for faster shipping and improved overall efficiency in your eCommerce business.
