By taking advantage of kitting in warehousing, shippers can meet consumer demands, drive profits, and reduce overall business expenses. To make the most of kitting, it’s important to understand how it impacts warehousing and shipping.

Key Takeaways

  • Kitting is the process of combining multiple products into a single unit for sale to customers.
  • Items in a kit should work toward a common goal, such as lifting a vehicle above its stock suspension height. This contrasts with bundles and fully assembled products.
  • By kitting items together, shippers can move through them at a faster rate and increase revenue while making room for new goods at their warehouse.
  • A third-party logistics (3PL) warehouse can offer storage, kitting, and shipping services to businesses looking for knowledgeable logistics professionals. 

In the guide below, we’ll take a look at the basics of warehouse kitting and the advantages it offers to businesses.

How Kitting in Warehousing Works

When you build a kit, multiple related products with individual stock-keeping unit numbers (SKUs) are packaged together as single . 

In practice, you can break kitting down into three steps:

  • Using sales and marketing data to decide if certain items you sell could work in tandem to address customer demands
  • Packaging those products together for sale as one unit
  • Distributing the kit to retailers or end users

This service is performed for a wide variety of industries including consumer electronics, auto parts,  and even fresh food. 

Consider these more specific examples of how kitting is used in warehousing: 

  • Book collections and anthologies 
  • Kitchen utensil sets
  • Performance upgrade packages for cars and trucks

Given that some goods could be applied to multiple overall kits, SKUs should be tracked separately for inventory and revenue purposes.

 
When discussing kitting, it’s important to remember the items included must be related to each other, which means they complement one another in some way. There are similar processes called bundling and assembly, but they differ from kitting in significant ways.

Differences Between Bundling, Kitting, and Assembly

Before we get much further into kitting, let’s distinguish these three processes.

  • Bundling: Bundled items don’t necessarily have to be complementary. This includes gift baskets containing a variety of goods like artisanal chocolates, hand soaps, and scented candles.
  • Kitting: In a kit, multiple items under one SKU work together toward a common purpose. A good example that will clarify the distinction between kitting and assembly is a kit car, which contains the parts required to build a vehicle from the ground up.
  • Assembly: If the car is put together before it’s shipped to you, it has undergone assembly and is no longer considered a kit. 

Now we can examine why businesses might choose to kit their goods and the benefits kitting can provide to everyone involved in the transaction.  

Why to Use Kitting in a Warehouse

Not every business will want (or need) to use a kitting service, so knowing when it’s useful is important. Below, I’ve listed some common reasons that businesses choose to kit their goods. 

  1. Lowering Distribution Costs

Sometimes, kitting reduces the costs of warehousing and shipping. Consider the following scenario.

An online retailer that sells office supplies notices that customers frequently purchase a pack of pens, a legal pad, and a padfolio together. By creating a kit of these items, the retailer can reduce pick and pack costs from their distribution partners. 

Companies can also reduce shipping costs by using custom packaging that reduces the size and weight of the shipments compared to if they had been shipped individually. 

  1. Providing More Choices for Customers

Offering pre-built options for customers to choose from can put them in the driver’s seat of their purchase. 

For instance, the video game company Nintendo offers pre-packaged console sets that include a game, controller, and all necessary cords. By offering multiple sets with different games, consumers feel empowered to choose the one that they like. This also spares the disappointment of receiving a console without a game to play immediately. 

  1. Offloading Slow-Selling Inventory

After analyzing sales data, a company might discover some related items aren’t selling well. This creates excess inventory. Kitting can sometimes solve this issue by increasing the value proposition of the items in question. 

Let’s say a book company publishes a 10-volume children’s series, but two of them aren’t selling well. 

By kitting those two books together and discounting the final product, they increase their chances of moving the products and turning a profit. You can see how this plays out in the tables below.

The first of two infographics presenting a hypothetical scenario in which a business may choose to kit related products together for sale. The graphic is labeled “Book Title”, “Cost Per Unit”, Units Sold Per Month at $20 MSRP”, and “Monthly Profits With 50% Margin”. The information presented reads as follows:

Children’s Book 1: $10.00 cost per unit, 20 units sold per month at $20.00 MSRP, $200.00 monthly profits with 50% margin

Children’s Book 2: $10.00 cost per unit, 10 units sold per month at $20.00 MSRP, $100.00 monthly profits with 50% margin

This gives us a total of $300.00 profit between both titles. Let’s see if we can do better.

Since the titles aren’t selling as well as others, the shipper decides to sell them in a kit at a discounted price with a lower profit margin, which achieves the following results.

The second of two infographics presenting a hypothetical scenario in which a business may choose to kit related products together for sale. The graphic is labeled “Book Title”, “Cost Per Unit”, Units Sold Per Month at $20 MSRP”, and “Monthly Profits With 42.8% Margin”. The information presented reads as follows:

Children’s Book Anthology: $20.00 cost per unit, 50 units sold per month at $35.00 MSRP, $750.00 monthly profits with 42.8% margin

As an anthology, the books are boxed under one SKU at the shipper’s 3PL and sold as a kit. Buyers are incentivized by getting a deal on previously higher-priced merchandise, and shippers can move their slower-selling inventory.  

With those advantages in mind, mistakes can occur during the kitting process. Businesses who aren’t familiar with the logistics aspect of this process can easily find their hard work ruined by customer complaints and shipping difficulties.

TThe Importance of Accuracy and Packaging

Several issues can arise from inaccurate packaging, and kitting does open up more opportunities for mistakes, simply due to the multiple components involved compared to a single item. 

These errors can include: 

  • Incorrect components
  • Kits missing pieces
  • Individual parts shipping from different warehouses due to inventory shortages
  • Damaged or improper packaging, leading to loss of goods

For instance, an inexperienced warehouse worker might use packing tape to secure a box of hardware to an otherwise complete kit and neglect to print a separate shipping label for the hardware. 

This can easily lead to the hardware box coming loose in transit. , with no separate tracking number, there would be no way to trace it. Everyone from the shipper to the customer ends up losing money and/or time. 

This is just another reason to leave kitting in the capable hands of a 3PL with an expert staff who understands the ins and outs of storage, packing, and shipping.
