If you run a Shopify store, you already know that acquiring new customers is expensive. What if the easiest revenue you could earn is sitting right inside your existing checkout flow? That is exactly what cross-selling unlocks. Studies across e-commerce consistently show that merchants who actively implement cross-sell strategies see their average order value (AOV) increase by 10 to 30 percent — without spending an extra dollar on ads. In this guide, we’ll review the top 7 best Shopify cross sell apps in detail to help you find the most suitable one for your store. Let’s get into it.
What to look for in Shopify cross sell apps
Before diving into the best Shopify cross sell apps available today, let’s quickly clarify two terms that often get confused:
- Cross-selling means suggesting complementary products alongside what a customer is already buying. If someone adds a camera to their cart, recommending a memory card or a carrying case is cross-selling.
- Upselling means encouraging the customer to buy a more premium or higher-priced version of the product they’re already considering.
Not every cross sell Shopify app is built the same. Before installing the first one you come across, here are the criteria that separate a great app from a mediocre one:
Placement flexibility. The best Shopify cross sell app lets you display offers across multiple touchpoints — the product page, the cart drawer, the checkout page, and post-purchase pages. Each stage of the funnel has different conversion rates, and having the flexibility to test all of them matters.
AI-powered recommendations vs. manual rules. Some apps use machine learning to automatically suggest products based on purchase history and browsing behavior. Others let you manually define which products are recommended alongside which. Ideally, you want both options. AI handles scale; manual rules give you control for hero products or seasonal promotions.
Pricing model. Options range from fully free tiers to flat monthly subscriptions and to commission-based models that take a cut of the revenue generated. For small stores, free or flat-rate plans are safest. Commission models can eat into margins at scale.
Ease of setup. If you need a developer to configure the app, it adds friction and cost. No-code visual editors are standard among the top apps today — you should be able to go live in under 30 minutes.
