Batch Picking: A Comprehensive Guide with 7 Best-Practices

Discover the 7 best practices of batch picking in warehouses, including its process, comparisons, pros and cons, and integration with AutoStore technology.


Picking is a crucial stage in the order fulfillment journey. However, a significant challenge to warehouse efficiency arises when workers spend excessive time picking items for a single order.

There are several approaches to the picking process, including pick-to-order, zone, wave, cluster, and notably, batch picking, which stands out for its efficiency.

Batch picking is particularly beneficial when there are multiple identical orders to fulfill at the same time, for example during peak seasons.

This article delves into the intricacies of batch picking, comparing it with other picking methods, exploring its suitability for different business models, and examining the challenges and best practices associated with its implementation. Additionally, we explain how automated goods-to-person systems such as AutoStore enhance batch picking processes even further, showcasing how modern solutions are revolutionizing warehouse operations.

What is batch picking?

Batch picking is a process used in warehouses and distribution centers where a worker collects multiple orders simultaneously. In this method, the worker follows a picking list that includes items from several orders. The items are gathered in a batch and then sorted later into individual orders. This approach differs from picking one complete order at a time, and it aims to increase efficiency. In a manual warehouse, batch picking can reduce the amount of trips a worker needs to make around the warehouse. In an automated warehouse, batch picking can reduce the amount of times the system needs to deliver products to the picker.

Let’s have a look at how batch picking works in practice.

Batch picking in practice: The online bookstore example  

Here’s an example of how batch picking works through the lens of an online bookstore.

  • Order aggregation and list creation: The warehouse receives several orders from different customers. Each order contains various different books. The warehouse management system (WMS) combines these orders into batch lists for each book. For instance, 10 customers ordered "Harry Potter and the Philosopher's Stone" and 5 customers ordered "Star Wars: The Return of the Jedi".
  • Picking: The warehouse worker uses the lists and picks 10 copies of the Harry Potter book and places it in separate containers for each customer. They then pick 5 copies of the Star wars book and places them in each container accordingly. This means they can pick several products in batches, saving time. If the warehouse operates with an AutoStore, the worker will pick these books from inventory Bins presented at the workstation and place them in containers as depicted above. If the warehouse is manual, the warehouse worker will walk around the warehouse, and pick the various books in batches from different aisles in the warehouse.
  • Sorting: If you don't want to sort orders immediately as described above, you can first complete the picking, then do sortation as a separate step. After picking all the required books from the batch picking lists, the worker would bring them to a sorting station. There, the batch of books will be divided into individual containers for each order. This is more often the case in a manual warehouse.
    Another point to be aware of is that if the order picking is automated, it is also possible to automate sortation, enhancing efficiency even further. Upon picking the products e.g. from the AutoStore workstation, instead of placing them in individual containers, the warehouse worker can place them on a conveyor or individual mobile robots that will be integrated with the WMS and automatically sort the orders into separate containers.
  • Order accuracy check: A quality check is conducted to ensure each order is complete and accurate. This step is crucial to avoid errors like missing titles or incorrect quantities. Automating the picking and sortation process should reduce errors significantly.
  • Packaging and dispatch: Once sorted and checked, each order is packaged. The orders are then dispatched to the respective customers, completing the batch picking process.

To fully understand the concept of batch picking, comparing it to its counterparts - other picking methods - is crucial to get the full picture.

Batch picking compared to other picking methods

In warehouse operations, selecting the right picking method is essential for efficiency and productivity. Batch picking, individual order picking, wave picking, zone picking, and case picking each have unique characteristics that suit different operational needs. Let’s dive into each of the picking methods and how they compare to the batch picking method.  

How does batch picking differ from individual order picking?

As introduced above, batch picking consolidates order lines from multiple orders, improving picks per storage location. This method enhances efficiency, for example in systems like AutoStore, by increasing picks per Bin presentation. Batch picking necessitates later sorting of items, using systems like put-walls or sorters. This method is more efficient than individual order picking, where each Bin presentation represents a single order line. However, it should be noted that batch picking requires sophisticated software for managing the flow of batches.

The AutoStore system, especially with its FusionPort feature, significantly streamlines the batch picking process in warehouses.

How does batch picking differ from wave and zone picking?  

Wave Picking: Wave picking schedules picking activities into distinct waves based on criteria like shipping times. Unlike batch picking, which groups similar items, wave picking doesn't inherently group order lines.

Zone Picking: Zone picking divides the warehouse into zones, with pickers responsible for specific areas. They pick items within their zone for multiple orders, in contrast to batch picking, where pickers may travel throughout the warehouse.  

How does batch picking compare to case picking?

Case picking involves selecting entire cases or boxes of products, often used for larger orders or when products are pre-packaged. Unlike batch picking, which might involve collecting varied individual items, case picking is typically less complex in terms of sorting post-pick. Batch picking can be more time-consuming due to the need to gather various individual items and later sort them, whereas case picking generally involves handling larger, pre-sorted units.

Through these comparisons, we see that batch picking's strength lies in its ability to group orders for efficiency, though it requires additional steps for sorting. In contrast, individual order picking is simpler but less efficient, while wave and zone picking focus on scheduling and area-specific tasks, respectively. Case picking stands out for its handling of larger, pre-packaged units, offering a different efficiency in certain operational contexts.  

So, when is it relevant to consider batch picking over other picking methods, and for what industries is batch picking a wise choice?

Case picking involves selecting entire cases or boxes of products, often used for larger orders or when products are pre-packaged.

When to consider batch picking (industries)

Batch picking is particularly effective for businesses that align with certain operational profiles:

  • E-commerce platforms: Ideal for e-commerce businesses due to the high volume of orders and variety of products, batch picking facilitates the efficient handling of multiple items per order.  
  • High volume of similar SKUs: Businesses with many orders containing similar SKUs, especially those with a significant portion of high-demand items, can benefit greatly from batch picking. This is often seen in industries with strong 'A' category items in their inventory.
  • High throughput requirements: Operations that need to process a large number of orders quickly, such as fast-paced retail or distribution centers, find batch picking advantageous for its efficiency in reducing travel time within the warehouse.  

In summary, batch picking is best suited for environments with diverse product ranges and high order volumes, particularly in e-commerce and situations where reducing picker travel time is crucial.

Pros and cons of batch picking  

Batch picking offers several benefits but also presents unique challenges. Understanding these can help your business evaluate its suitability for your specific needs.

Pros of batch picking

  • Increased efficiency: By collecting items for multiple orders simultaneously, batch picking reduces the number of trips a picker must make, enhancing overall operational efficiency.  
  • Reduced picker travel time: This method significantly cuts down on the distance that pickers need to traverse within the warehouse, saving time and energy.
  • Optimized for high-volume operations: As mentioned, especially beneficial for businesses with high order volumes, such as e-commerce platforms, where orders often contain a variety of items.  

Cons of batch picking

  • Decreased performance later in shifts: A notable challenge is the potential depletion of batch potential as a shift progresses. Early in the shift, high batches allow for efficient grouping, but later waves may have less grouping potential, leading to a notable performance decrease.  
  • Increased workforce requirements for sorting: Although batch picking might reduce movement in item collection, it could increase movement if a putwall or similar sorting system is used. This additional movement isn't necessarily negative but depends on the nature and extent of the movements required.
  • Complexity in planning and software requirements: Effective batch picking requires sophisticated software to manage order profiles and batch flows, adding complexity to the planning and operational processes.  
  • Necessity for sorting post-picking: Unlike methods where items are directly picked into their final shipping container, batch picking requires an additional sorting step, adding time and complexity to the process.  

To sum up, batch picking offers efficiency and reduced travel time, making it ideal for high-volume operations. However, it also brings challenges like decreased performance over time and complex sorting requirements. Weighing these pros and cons is obviously essential for deciding if batch picking is the right fit for your specific warehouse environment.

7 Best practices for implementing successful batch picking

Implementing batch picking in a warehouse environment requires careful planning and understanding of your operations. Here are some best practices to ensure effective batch picking:  

  1. Understand your assortment and order profile: A deep understanding of your product assortment and order profile is crucial. Be aware of how changes in the order profile, possibly due to sales or marketing campaigns or new assortments, can impact the efficiency of your batch picking strategy. If the order profile no longer supports batch picking, efficiency can be compromised.
  2. Regularly review order profile: Regularly analyze your order profile to understand how it affects the batches you are building. This involves tracking changes over time and adjusting your strategies accordingly.  
  3. Communicate with key departments: Maintain open communication with departments that influence the assortment, such as sales, marketing, and inventory management. Their decisions can directly impact the order profile, and hence, the efficiency of your batch picking process.
