Putwall for efficient order fulfillment in ecommerce warehouses
A putwall (or put wall) is a solution for companies that process a large number of orders a day. It’s ideal for e-commerce warehouses, where goods need to be shipped as fast as possible.
What is the put wall system?
A putwall is an order processing solution for businesses with high daily workloads. It consists of a wall with individual compartments, each assigned to a customer order.
To work with the putwall system, associates travel through the warehouse, picking products for several orders at once (i.e. batch picking). They then place the goods in the slots for subsequent packing and shipping. This work method streamlines order sorting and fulfillment, improving logistics management efficiency.
Advantages of using put-to-wall in the warehouse
Facilities that operate using a putwall system benefit from greater agility and accuracy when sorting products:
- Picking productivity. For companies with high daily workloads, processing orders one by one can be inefficient. The warehouse is more productive when multiple orders are managed quickly and accurately.
- Error reduction. With this system, merchandise is organized into specific compartments for each order, reducing sorting errors.
- Scalability. The number of putwall locations can be expanded as warehouse operations grow.
- Space optimization. Sorting products in a single space makes better use of the logistics facility.
- Compatibility with other technologies. Put-to-light devices can be integrated to assist associates in placing the correct unit quantities in the right locations.
- Improved resource utilization. This method requires shorter goods handling times and fewer associates to handle large orders, lowering operational costs.

Differences between put-to-wall and put-to-light
The concepts of putwall and put-to-light are often confused since both are solutions designed to streamline order fulfillment and sorting.
- Put-to-wall. This solution focuses on sorting multiple orders at a centralized station following batch picking.
- Put-to-light. This order fulfillment technology consists of an electronic display that shows associates the correct location and quantity for each item.
While the putwall optimizes the sorting of goods ready for packaging, the put-to-light system facilitates the task to speed up order fulfillment.
In both cases, using a warehouse management system like Interlake Mecalux’s Easy WMS improves picking efficiency and minimizes errors. Put-to-light devices, for example, are controlled by this software, which sends detailed instructions to associates.
Order fulfillment process with the put-to-wall system
Batch picking requires sorting the picked merchandise into compartments. There, the items for each order are gathered before being packed and shipped to customers. While the process is flexible and can vary by facility, the typical sequence is as follows:
- Order receipt. When a company receives an order, the logistics software selects the necessary products and sends instructions to associates to locate them in the warehouse.
- Product picking. Operators move through the warehouse with a cart, grouping items for multiple orders at once.
- Sorting in the putwall. Pickers place the merchandise for different orders into designated slots, with each location corresponding to a single order.
- Order verification. Associates check that orders are complete and error-free, usually with the help of a WMS.
- Packing and labeling. Once verified, items are removed from the putwall and transferred to the packing and labeling area. There, they are placed in the appropriate unit load for streamlined distribution to customers.
Specialized software like Mecalux’s Multi-Carrier Shipping Software can optimize the packing and shipping process. This additional Easy WMS module organizes and automates operations in the final stage of the supply chain. The system guides associates by indicating which items to pack and whether to consolidate them into a single unit load or multiple ones. At the same time, it transmits essential shipping information to carriers, (e.g., the number of packages, their volume, and weight).

Putwall in the warehouse for order picking productivity
With the rise of e-commerce, logistics centers need solutions for processing growing numbers of orders in the shortest possible time. A putwall is a solution for handling customer orders more efficiently for fast, on-time delivery. It works in tandem with the WMS, which organizes operations and minimizes errors.
