As a retailer or a D2C brand, you may have considered creating product bundles as a marketing strategy or to improve your sales. And you are right to consider that option! However, have you also considered the next steps you need to take when it comes to logistics and fulfillment for product bundles? In this blog, we share with you the main reasons and challenges that you can face, and some expert tips to successfully sell and fulfill your product bundles.

What is a product bundle?

Instead of selling products one by one, retailers choose to group them and sell them as a combined package with adjusted prices.

Usually, product bundles are made of different items, whether they are complementary or similar. The prime example of using product bundles is the beauty industry, more specifically, the skincare routine products.

In some cases, when retailers sell multiples of the same product, a pack of cans, for example, it’s called a multipack bundle.

Therefore, product bundling is a very popular method for e-commerce merchants and retailers to:

  • Increase sales and profits
  • Move out stock and excess inventory
  • Improve customer experience by fitting their needs better

Seasonal product bundles

A great example of product bundles, that we probably all know, is the seasonal bundles. Usually, brands and retailers use special occasions (Christmas, Easter, Summer, etc.) to assemble their products according to a certain theme. It’s a good idea to increase sales and customer loyalty.

For online retailers, seasonal product bundles are the typical use case and the easiest way to offer such sales. But since it’s usually linked to a peak season, the logistics and fulfillment topics are even harder to manage.

Top reasons why retailers should start to bundle their products

There are several reasons why retailers should start product bundling and how it could help them in their business. 

Before diving into those, let us look at Amazon for a brief second. We have all experienced the cluttered Amazon product pages full of text, pictures, descriptions, reviews, etc. But what made Amazon so popular and successful is its “recommendation” feature. Not all of them can be qualified as “bundles”, but it’s interesting to note (even if the data is already 8+ years old) that after launching this feature, McKinsey estimated that 35% of Amazon sales came through it.

Therefore, product bundles can be a huge leverage for sales. However, there is more behind this strategy. Let’s take a look at three additional benefits of product bundling.

Move stock and sell slower-selling products

First of all, product bundling can help you with your inventory management, especially for products that you are having trouble selling.

As a retailer, you know that stocks may cost you a lot of money (storage, facilities, manpower, etc.). Whether these are fixed or variable costs, you want your products to move as fast as possible. 

By bundling slower-selling products (that you identify beforehand) together with your best-sellers, you might increase the overall perceived value of the package, and in the end, clear the shelves. At the same time, you can generate sales offers and sell your products in multipacks. This is especially interesting for perishable goods, during peak season, and after.

It is also a good strategy to clear out your unwanted and old inventory and make place for new items.

But be careful. You need to take into consideration the following:

  • Be consistent with the products that you are bundling together; ergo, do not mix apples and oranges
  • Keep track of stock levels of all items that you are bundling together, as you need to be able to fulfill the order entirely.


Use it as upselling and cross-selling tactics


Another reason to start a product bundling strategy is to boost your average cart size, and so increase your sales.

One of the main marketing strategies that you can try employing, is to add on your product page, cart page, or during the checkout process, a “Frequently bought together” feature to incentivize your customers to add your recommendations to their basket. This is what we call cross-selling.

You can then recommend add-ons and essentials products to bundle with your most popular products. Don’t forget to use discounts to maximize the impact.

One of the best use case examples is creating recommendations when people are buying electronics. For example, people that browse for a camera, would probably also need an SD card or a travel case, so recommending these products to the customers will facilitate high conversion rates.

Amazon cross-selling


Upselling is a different thing. It consists of selling a product or service with more added value, and therefore at a higher price than the customer was willing to pay initially.

However, in the e-commerce sphere, upselling is sometimes seen as a very aggressive tactic. You have to consider the customer needs and the right products. 

In practice, a lot of retailers use that strategy, especially in the cosmetics field and the food industry. Instead of selling your products one by one, create product bundles with several items, such as a skincare routine set or a diet plan, and sell them for a higher price. In return, you can offer free delivery.

It is also worth mentioning that upselling and cross-selling are not the only product bundles strategies available to you. There are also: 

  • Personalized product bundles
  • Discount packages
  • Assembled products

All these marketing strategies can help you create meaningful bundles, improve your conversions and sales, and move your stocks fast.

They [online retailers] also use the pre-sell, which is bundling or reducing the price of higher-priced products if you buy multiple products. The shipping cost might even be reduced or eliminated with a bundle.

Introduce new products to customers

Ultimately, product bundles are a good strategy to introduce new products to your customers. 

As a well-established e-merchant, launching new products can be stressful and challenging. Depending on the complexity and relevancy of the new products compared to your current ones, you can launch product bundles based on the use and the needs of pairing these new ones with your existing ones. This allows you to introduce new products seamlessly to your customers.

One of the typical examples of this approach is subscription-based products such as cosmetics or food. Subscription-based products are when customers order (or automatically receive) their package periodically; and here you can include your new product.

Overall, introducing product bundles into your business plan will help you increase your sales and move your stock fast. But doing this comes with a price; how to successfully fulfill those to your end customers? 

7 Fulfillment Tips for Your Success in E-Commerce

The main challenges of product bundling

Both on sales and marketing levels, product bundling seems like a really good opportunity to scale up your business. However, it comes with challenges.

On a pure branding/business side, product bundles (and products in a bundle) can suffer from a negative image. It may diminish the perceived value especially if there’s an associated discount. As a customer, I may be interested in this discounted bundle. But what if you start selling one of the products at a regular price simultaneously? Always keep in mind the pricing issue and the perceived value of the bundle and the products bundled.

Logistics of product bundles

If logistics of “regular” products is already hard to handle, logistics of product bundles won’t be easier… In the upcoming lines, you will discover the main challenges that mostly appear during the storage and pick & pack phases, and how byrd can solve them with our all-in-one tool for inventory management.

The wrong product in your bundle

It goes without saying that if you sell product bundles, you have to bundle the right products together.

This sentence has two senses. First, on the operational level, this implies a good logistics setup and tracking. You have to communicate internally (with your different teams) and externally (with your customers and your logistics partners) the products that you are bundling. This will help you to avoid misunderstandings in the ordering process and customer dissatisfaction at the delivery. Second, the strategic sense that implies research to bundle the right products together and generate sales. If your bundles are not consistent, you won’t benefit from the original idea which is: increasing sales.

Running out of stock one or several items

This may be the most difficult challenge when it comes to product bundles. Depending on your logistics and fulfillment setup, you have to keep track of every item’s stock level to successfully fulfill your bundle. If you run out of stock of one or several items that are included in the bundle, you should cease selling your product bundle anymore, or you will have to face dissatisfied customers due to orders not being delivered in time or at all.

This is especially relevant for seasonal product bundles. Take for example those Christmas boxes that are very popular. In addition to picking and packing the right product to assemble your bundle, you face the pressure of peak season with high demand and order volumes. Make sure you are prepared in advance (enough stock) and you can follow the stock level of each item.

The same goes for multi-pack bundles. If you sell canned food or beverages, for example, by unit or in packs, you have to make sure that, at every moment, you can sell both. To do that, your logistics setup and your inventory management are key to avoid backorders. 

If you manage your logistics and fulfillment internally, e-commerce platforms such as Shopify or WooCommerce have integrated add-ons for product bundles. If you go with outsourced logistics, we also have the solution for you.

Once you have created the bundle you can go to the “Inventory tab” in the dashboard where it will be displayed as a “Bundle” product, which helps you to find product bundles immediately. Moreover, you can see the availability of the stock right away for the bundle. byrd will always check for the lowest stock availability of the included products in order to ensure that you’re not overselling.

  • Lowest stock level: 512 
  • Numbers of products per bundle: 3 
  • 512/3 = 170
