Pick modules are an essential part of a warehouse or distribution center where order picking takes place. Order picking is a crucial operation that involves selecting products from storage locations to fulfill customer orders accurately and efficiently. Pick modules are designed to optimize this process by providing a highly organized and efficient environment for order picking. Get orders together faster with less errors and organize and move items more quickly throughout the warehouse.

What is a Pick Module?

A pick module is a component of a warehouse management system that is designed to optimize order picking efficiency. It is a multi-level system that consists of racking, conveyors, and other material handling equipment to help warehouse workers efficiently
pick and pack orders. In a pick module, each level is designed to optimize the flow of product through the system, reducing the amount of time it takes for workers to pick orders.


Pick modules are commonly used in e-commerce, retail, and distribution centers where there are high volumes of small to medium-sized orders. The goal of a pick module is to reduce the amount of time it takes for a worker to pick an order, while also reducing the number of errors in the picking process.

How Pick Modules Work

There are several different methods and technologies that can be used in a pick module. One common method is the "pick and pass" system, in which workers pick items from one level of the module and pass them down to the next level, where they are consolidated with other items to complete an order. This system is often used in conjunction with conveyor systems that move items from one level to the next.

Another common method used in pick modules is the "goods-to-person" system, in which items are stored in bins or totes that are delivered directly to the worker at a picking station. This eliminates the need for workers to travel to different areas of the warehouse to pick items, reducing the amount of time it takes to complete an order.

One example of a pick module in action can be seen in the Amazon Fulfillment Centers. Amazon uses a complex pick module system that includes conveyors, robotic arms, and a goods-to-person system to efficiently pick and pack orders. Items are stored in bins or totes and are delivered directly to workers at picking stations. Workers use handheld devices to scan barcodes and confirm that they have picked the correct item, reducing the number of errors in the picking process.

Another example of a pick module in action can be seen in the distribution centers of clothing retailer Zara. Zara uses a "pick and pass" system in which workers pick items from one level of the module and pass them down to the next level, where they are consolidated with other items to complete an order. Zara's pick module system is designed to handle high volumes of small orders, allowing the retailer to quickly fulfill online orders and keep up with changing fashion trends.
