Warehouse Kitting 101: Process, Benefits & More
Warehouse kitting is the process of packing individual products that complement each other into a single package, then selling the pack together as a “kit”.
This inventory technique offers several benefits in the warehousing industry, from reduced shipping and packing costs to space optimization and more.
We’ll share all you need to know about kitting in a warehouse, including the step-by-step process and how our automated solutions can help further streamline warehouse operations.
What is Kitting in a Warehouse?
Kitting in a warehouse, also known as warehouse kitting, is the process of packing individual yet related stock-keeping units (SKUs) into a single package and shipping them as a kit.
Kitting in a warehouse allows you to improve picking efficiency, cut picking costs, save warehouse space and more.
Kitting vs. Bundling
While the terms kitting and bundling are often used interchangeably, there’s a stark difference between the two.
Kitted items are individual yet complementary goods that are packed into a single kit and are sold as one unit.
Examples of kitting include:
- A box of several books
- A phone charger, case, screen protector, and earbuds packed into one box
- A gaming console, controllers, and other freebies such as discs and headphones packed into one box
On the other hand, bundling is a broad term used to describe the process of packing several SKUs together, regardless of whether they complement each other.

Benefits of Kitting in a Warehouse
From maximizing existing warehouse space to preventing overstock, here are five reasons why kitting in a warehouse is paramount to streamlining warehouse operations.
The Kitting Process in a Warehouse
So how does kitting in a warehouse work exactly?
1. Determine Which SKUs Go Into the Kit
First, identify your goals to determine which individual items will be kitted.
- Do you want to improve sales revenue or meet seasonal demands? Kit products that are typically purchased together.
- Do you want to increase your customer’s average order value? Kit new products together with fast-moving items.
- Do you want to prevent overstock? Offload slow-moving items by kitting them with more popular, fast-moving products.
2. Identify Who Will Assemble the Kit
Your warehouse operators can either pre-assemble the kits, or you can outsource the assembly and kitting services to a 3PL provider that will ship and label the final SKU.
3. Assign a New SKU
Next, your warehouse operators assign a new SKU number to the kit to monitor sales and inventory. Instead of tracking each individual product SKU, you’ll only track the kit’s SKU number moving forward. This simplifies and streamlines the labeling and tracking process.
4. Pick and Assemble the Kit
Here’s where your warehouse operators locate the SKUs needed to pack the kit.
Picking aids such as barcode readers and picking carts can help them navigate their way around the facility to locate the accurate picking areas. Once the individual goods are picked, operators can pre-assemble the kits, which will then be ready for storage.
If your warehouse is automated, operators can utilize automated storage and retrieval systems to help store and batch-pick multiple kits into totes or bins.
5. Ship the Kits to Customers
Once orders are received, your warehouse operators can ship kitted items as a single order to your customers, reducing lead time, cost, and mistakes.
How to Automate the Kitting Process With Modula Solutions
While kitting in a warehouse can help you save valuable space, prevent overstock, and more, warehouse operators must manually navigate multiple storage aisles and pick individual goods to form a kitted order.
This manual approach to warehouse kitting is tedious, labor-intensive, and can be prone to human mistakes — which is where we come in.
At Modula, our cutting-edge automated solutions transform your material handling and streamline your warehouse kitting, thanks to advanced storage, picking, and inventory management systems.
An efficient fulfillment process increases company profit and customer satisfaction.
Let’s dive right into our solutions.
