What is Order Picking in E-commerce?

Order picking is the process of retrieving products from warehouse inventory to fulfill customer-requested orders. It is the first and most critical step in the order fulfillment process. It directly influences both the delivery speed and accuracy in ecommerce.

Traditionally, warehouses depend on manual labor. In this workers that are also known as pickers retrieved those products from shelves. The quality of these pickers affected the success of the entire supply chain process. However, with advancements in technology, ecommerce businesses have transformed order-picking solutions. Now they use technology automation to improve the delivery speed and precision.

At present modern warehouses now integrate robotics, RF scanners, and AI-driven software to manage their business operations. These technologies have completely changed the complete order-picking process. However traditional methods continue to be widely used due to their effectiveness in all sorts of warehouse setups.

Why is Order Picking Important?

An efficient order-picking system provides different types of advantages to e-commerce companies. These are listed below:

1. Cost Reduction: Automation helps reduce warehouse operational expenses after properly minimizing labor-intensive tasks.

2. Faster Order Fulfillment: Automated picking lists optimize order grouping & assign tasks efficiently. It cuts down the order processing time.

3. Improved Order Accuracy: Accurate picking reduces errors. It further improves customer satisfaction and long-term loyalty.

4. Optimized Workforce Productivity: A well-structured picking system enables pickers to work efficiently. It further reduces errors and improves the overall warehouse performance.

Due to the above benefits, modern e-commerce stores continuously refine their order-picking strategies in order to increase business efficiency. Now, let’s explore some of the best order-picking methods used in eCommerce to manage order fulfillment operations.

Top Order Picking Methods for eCommerce

1. Single Order Picking

You will relate to this method, in case you have ever done grocery shopping with a list. Single-order picking is the simplest picking strategy of all the options. A warehouse worker also known as a picker usually retrieves items for one order at a time from warehouse shelves. After that, he brings them for packing. This technique is ideal for small warehouses that handle a low order volume.

Pros:

1. Simple and easy to implement.

2. Reduces errors by focusing on one order at a time.

Cons:

1. Inefficient for large-scale operations due to increased travel time.

2. Can slow down the fulfillment process. 

2. Batch Picking

Imagine running a grocery store and picking items for multiple customers at once instead of making separate trips. That’s batch-picking in a nutshell. Instead of handling one order at a time, a picker retrieves similar SKUs for multiple orders simultaneously, reducing travel time.

It is ideal for warehouses that have frequent orders of the same items.

Pros:

1. Saves time by reducing repeated trips.

2. Enhances efficiency for small items and frequent orders.

Cons:

1. Not ideal for large or heavy items.

2. Requires an organized inventory and efficient sorting process.

3. Multi-Batch Order Picking

This is an advanced step in the earlier batch-picking method. Multi-batch order picking allows workers to collect multiple SKUs for different orders in a single trip. In this technique, instead of making several runs, pickers use multi-tier picking carts to gather products for multiple orders at once.

It is ideal for large warehouses that handle high-volume orders.

Pros:

1. Drastically reduces travel time.

2. Improves overall efficiency.

Cons:

1. Requires careful sorting and organization.

2. Workers may need additional training.

4. Zone Picking

For example- imagine a relay race in which each runner passes the baton to the next teammate. In the zone-picking method- warehouses are divided into specific zones. And each worker is responsible for picking items within their designated zone. Once items from one zone are picked, the order moves to the next zone.

It is an ideal option for large fulfillment centers that handle different types of inventories.

Pros:

1. Reduces congestion and improves workflow.

2. Improved organization by assigning workers to specific areas.

Cons:

1. Requires a well-structured warehouse layout.

2. Can be slower than batch picking for smaller warehouses.

5. Wave Picking

Think of wave picking as an airport departure schedule. In this technique, orders are grouped into waves based on different parameters. These are priority, location, and shipping deadlines. It provides a warehouse option to optimize picking schedules.

Pros:

1. Helps coordinate picking with shipping schedules.

2. It is best for businesses to have multiple delivery deadlines.

Cons:

1. It requires a Warehouse Management System for proper scheduling.

2. Can be costly to implement.

6. Cluster Picking

Cluster picking utilizes technology-driven picking systems. It allows workers to pick multiple orders simultaneously and place them in separate bins. It eliminates the need for sorting later and speeds up the process.

This technique is best for those warehouses that use barcode scanners and automation.

Pros:

1. It reduces errors by making sure of an accurate item placement.

2. Saves time and improves order accuracy.

Cons:

1. Requires investment in scanning technology.

2. Workers need training to handle scanning equipment efficiently.

7. Pick-To-Light Systems

This advanced system guides pickers using LED lights that illuminate the exact location of an item and further reduce the guesswork. After properly following the lights, pickers can not retrieve the items faster and with greater accuracy.

This technique is ideal for those types of warehouses looking to improve picking speed and reduce human error.

Pros:

1. Increases picking accuracy.

2. Easy to integrate with existing WMS.

Cons:

1. Initial setup costs can be high.

2. Not as effective in dynamic warehouse layouts.

8. Voice Picking

Pickers receive verbal instructions from an Order Management System (OMS) using the help of wireless headsets. This hands-free approach is beneficial while handling bulky or hazardous items.

It is an ideal technique for Warehouses that deal with large, heavy, or hazardous materials.

Pros:

1. It reduces the related picking errors.

2. Improves efficiency by keeping workers’ hands-free.

Cons:

1. Requires investment in voice technology.

2. Training is needed for new employees.

9. Mobile Scanner-Based Picking

Pickers use mobile barcode scanners to scan items. This ensures proper accuracy before adding them to an order. The system helps identify mistakes in real time and optimizes picking routes.

Best For: Warehouses aiming for high accuracy in order fulfillment.

Pros:

1. Reduces human errors significantly.

2. Enhances order tracking.

Cons:

1. Requires a digital inventory management system.

2. Pickers need to be trained to use scanners effectively.

10. Collaborative Mobile Robots

In 2025 and further, Robots are going to change warehouse operations by assisting workers in transporting picked items. These robots autonomously look for the warehouse and further eliminate unnecessary travel for human workers.

Best For: Large eCommerce warehouses investing in automation.

Pros:

1. Increases efficiency and reduces travel time.

2. Works alongside existing order-picking methods.

Cons:

1. High initial investment.

2. Requires warehouse infrastructure adjustments.
