When looking for ideas to increase sales in E-commerce, we often focus on promotions, new products, or better advertising. Looking for more, less obvious ways to attract customers and increase the value of their shopping cart, we turn to product sets. This solution not only sells items, but also shows customers ready-made shopping ideas: sets of cosmetics, multi-packs of pet food, or sets of supplements. For many people, it’s convenient because they can buy more in one step and get the package at a better price than if they purchase separately.

Introducing kits gives customers choice and ease of purchase, while promoting products that may not always be at the top of their shopping list. As a result, your store increases revenue and builds loyalty among customers eager to return for more complete solutions.

Selling kits in E-commerce brings several benefits that can clearly affect your store’s performance and customer satisfaction. Here’s how sets can change the way your store operates:

The introduction of product kits can take different forms depending on the industry. Each sector has its own specific needs, and properly selected kits can effectively address these expectations, attracting customers and increasing sales. 

From pet accessories and cosmetics to supplements, kits allow you to create consistent, attractive offers that simplify the shopping process and increase the value of the shopping cart. Here’s a look at how different industries are using kits and which approaches yield the best results.

In the pet industry, kits are a great idea because they allow customers to buy everything they need in one transaction. Puppy starter kits, for example, work well, containing a cross-section of the products needed to get started, such as a collar, sleepers, the first food in various flavors to be tested, and treats, tailored to the age of the pet. 

At our client BazarPupila.pl, the canned food sets, packaged 12 pieces each, have proven to be excellent; thanks to their use, the average basket containing canned food has increased by 32%. This did not require any changes to the warehouse, thanks to our proprietary solution for Shopware 6 for kits, the inventory integrates with the product contained in the kit, and in the order they appear as single products, thanks to which no modifications were required in the integration with Baselinker and ERP.

In the beauty industry, kits can be particularly attractive because they allow customers to purchase several products at once, often at a favorable price. An example is Kylie Cosmetics, where you’ll find a wide range of kits in a dedicated section called “Bundles & Sets.” Customers can choose bundles for multi-step care or sets of several colors of the same cosmetic. 

Similarly, our client Yope.me, known for its natural products, offers kitchen cleaning kits and bath care sets, among other products. Yope customers will find bundles that address a variety of needs, from cleanliness to grooming, and in addition, the products appear in the “Bargains” section, giving them greater visibility and highlighting the benefit of purchasing the sets. As a brand, Yope is available in many chains, and the use of online-only kits helps attract customers to shop at the manufacturer’s store.

In the health and supplement industry, sets are also gaining popularity. In stores for supplements and natural products, there is a “Frequently Bought Together” section that shows popular product combinations. This makes it easy for a customer to match a supplement ordered with a complementary product, such as a vitamin or natural formula. This feature, based on data from other users’ previous purchases, makes shopping more intuitive and responsive to real customer needs.

On platforms such as Allegro and Amazon, product bundles are emerging as an attractive option, especially for repeat purchases. On Amazon, the “Frequently bought together” feature recommends products that fit into a selected category or form a useful whole, such as shoes bundled with a grooming product. 

Such a model not only inspires customers to buy, but also speeds up their decision. Thanks to the algorithms, the sets are matched to users’ previous purchases, allowing them to choose the right products without having to search for them themselves.

Introducing kits to your offer is just the beginning – the key lies in preparing and promoting them properly, so that customers see their value and are eager to reach for them. A well-thought-out strategy, based on market analysis and gradual building of the offer, will help create kits that really attract attention. 

It is also important to ensure their visibility and ease of access on the store’s website, which increases the chances of conversion. In addition to the technical part itself, it is also very important to prepare appropriate graphics that attract attention and communicate the benefits of buying a kit, such as speed of purchase or lower price.

Before you introduce kits, it’s a good idea to start by understanding what’s already working in the market. Analyze which kits are popular in your industry – you can use market analysis tools or look at what competitors are offering. 

This will help you avoid blind experimentation and build an offering that addresses real customer needs faster. It’s also a good idea to keep an eye on reviews and customer feedback, which will indicate what is particularly appreciated and what is missing from the products already available. Of course, you can also contact us, and we will help you build a strategy and implement it from the technical side.

It’s a good idea to introduce packages gradually. At first, you can offer a few basic packages – choose top products or products that are most often bought together or complement each other. This will make it easy for customers to see the value of the sets, and give you time to test their popularity. 

Once you see which combinations work best, you can start to expand the offer by adding more packages and tailoring them to different customer needs. This gradual construction of the offer will allow you to better manage your inventory and develop a consistent brand image.

Kits should be easy to find. One way to promote them is to add information on product cards – for example, through a “product also available in a set” section. This is a simple procedure that reminds the customer of the sets and encourages them to buy more products.

You can also include selected sets in product listings or create dedicated categories where the customer can find all available bundles. This makes the sets more visible and easier to search, which positively affects sales.

A landing page dedicated to kits is a great way to promote them. Such a page gathers all available packages in one place, so customers can browse the entire range of kits without having to search for them on different subpages of the store. You can also link it in promotional campaigns, newsletters, and social media to direct traffic to the full offer. Such a page is navigation-friendly and creates an impression of consistency, showing that kits are an important part of your offer.

E-commerce kit management is a challenge that requires thoughtful technical solutions. It is crucial that inventory, invoicing, and integration with ERP systems work smoothly and seamlessly. Here’s how to approach these issues to make kit sales efficient and easy to use.

When setting up kits on an E-commerce platform, one of the challenges is inventory management. The inventory of a kit must be automatically updated based on the availability of its component products. 

For example, if a kit contains several different products, the number of available kits should be dynamically calculated based on the lowest inventory of one of the component products. This avoids a situation where a customer orders a kit, and after placing the order, it turns out that one of its components is missing.

Of course, many companies work around technical shortages by giving separate codes, e.g., SKUs for the kit itself, but by having to separate inventory for the kit, this is a highly unscalable solution.

Invoicing of product bundles can be done using two different techniques that affect how they are managed in E-commerce and ERP systems:

Approach 1: Kit as a separate product with an independent SKU.

The first approach assumes that a kit is treated as a separate product with its own unique SKU. Its inventory is managed through the ERP system, which facilitates invoicing – the kit appears as a single item on the invoice. While this is simple to implement on the technical side, it can lead to problems with offer flexibility and make it difficult to manage the excess products in the catalog and their prices.

Approach 2: Kit without an independent SKU.

The second approach assumes that a kit is treated as a collection of products that appear as separate items on the invoice after an order is placed. In practice, this means that the kit does not have an independent SKU. As a result, the customer sees the component products on the invoice, which simplifies integration with the ERP system and eliminates the need to create a new SKU. This approach, however, requires a suitable E-commerce solution to automatically manage this form of sales. In most cases, this is our preferred solution.

Integration with ERP systems is key to keeping inventory management and invoicing running smoothly. With such integration, orders containing kits are interpreted by the ERP as purchases of individual products, making it easier to post and monitor inventory. It’s also beneficial for returns, as they can be billed as separate items, giving you greater flexibility.

As part of the development of the Shopware platform, we created a plug-in that allows full flexibility when creating sets. You can freely configure sets from existing products in different configurations and quantities, and inventory is automatically updated. In addition, the plug-in calculates the benefit to the customer of buying a set, which is visible as a discount in the shopping cart.

Our solution also introduces advanced logic – in the shopping cart, the customer sees the set as one product, but after placing the order, the order details show the individual items. This facilitates integration with an ERP because the system interprets the order as a purchase of standard items, which streamlines invoicing and subsequent returns. This allows stores to create elaborate kit offers without having to manage additional SKUs in the ERP system.

Bazar Pupila is an online store that offers dog and cat food and products with a focus on the needs of pet owners. The platform was based on Shopware 6 and integrated with Baselinker and ERP Optima systems, enabling easy management of orders and inventory. 

One significant improvement was the introduction of product bundles that better meet customer expectations. For example, kits of different treats allow pet owners to purchase more products at a favorable price, allowing them to test different flavors and choose their pets’ favorite treats. These types of solutions have contributed not only to an increase in the value of the shopping cart but also to greater customer satisfaction, which is evident in the positive feedback about the store. 

Introducing kits to sales is an easy way to increase basket value and boost sales. Customers are eager for product bundles because they see them as convenient and beneficial, and for the store, it’s an opportunity to promote less popular products and make additional profits. Thus, kits are becoming a strategy that combines customers’ needs with the store’s business goals.
