2 best cross-sell apps for Shopify in 2025

Propel the profits of your ecommerce store with cross sell offers your customers can't resist. For most online stores, 70-95% of revenue comes from cross sell funnels. Being able to upsell and cross-sell are sales tactics that help increase average order value.

There is a multitude of ways to cross sell products on your Shopify store successfully. Popular methods include adding an on-brand frequently bought section to your product page and making smart cross sell suggestions with add-ons at the cart.

In this article, you'll learn about Shopify cross-selling, and we'll share with you the two best Shopify cross sell apps we recommend.

What is a Shopify cross-sell app?

A cross-sell app is a plug-in that entices your customer to add more to their order. A great perk of having a Shopify store is that Shopify store owners have many cross sell apps to choose from that can be installed.

The key benefits of using a Shopify cross-sell app:

‍‍

• ‍Saves time: having a third-party app host your cross selling offers allows you to focus on other areas of your Shopify store without manually creating, updating and rotating cross sell offers‍
• Maximize sales: Cross selling apps allow consumers to add items to their backset with just a few clicks making the overall process seamless‍
• Customer satisfaction: cross sell apps can propel sales with offer campaigns that improve the customer journey, like offering them add-ons or product upgrades with cleverly placed frequently bought sections

So, now that you know our reasoning for our cross sell recommendations, let's explore the two types of cross sells: pre-purchase and post-purchase cross sell funnels.

What is the difference between pre-purchase and post-purchase cross-sells?

You can cross-sell to a customer on your Shopify store in two ways: pre-purchase and post-purchase. Both of these strategies can help cross sell products, and they both achieve similar results. The only difference is where in the buyer's journey these marketing features are used.

Pre-purchase cross selling

This strategy aims to increase the average order value before customers check out on your store. Some customers respond better to offers before they make a purchase. Offering discounted cross sells can help build loyal customer relationships and increase the number of products in their cart.

On an ecommerce store, there is plenty of opportunity to cross sell via:

‍

• ‍Product page: by showcasing your products in the best light with clear images and relevant messaging, you'll improve the product page conversion rate and entice customers to buy your products on their first visit to your Shopify store‍
• Frequently bought sections: you can show customers other items that shoppers usually buy that relate to the items in their baskets. Frequently bought and product recommendation sections are great for displaying complementary products‍
• One click cross sell offers on the cart page: using banners, pop-ups and notifications, you can encourage customers to increase the number of items in their basket. Cart upsell offers are an excellent opportunity to promote related frequently bought products

Post-purchase cross selling

This cross selling strategy runs immediately after the customer has placed and completed their order.

Post purchase upsell and cross-sells use the already obtained customer data to provide an additional offer. The key idea is to create personalized customer recommendations using data like purchase history to suggest well-matched products.

So, now that you're all clued up on Shopify cross-sellling let us introduce you to the two top cross sell apps that will propel your ecommerce business.
