Best Shopify Upsell Apps for Increasing Average Order Value

Upsell apps help Shopify merchants recommend complementary products or offer bundle deals at key moments in the customer journey. A well-chosen upsell strategy can increase average order value without harming the customer experience.

Below we review ten established upsell apps across different approaches: bundle builders, post-purchase offers, cart-level recommendations, and AI-powered suggestions. Each has distinct strengths depending on whether you prioritize ease of setup, specific use cases, or advanced targeting.

How we evaluated these apps

We evaluated each app based on the core functions its name and documentation indicate: bundle-building capability, timing of offers (checkout, post-purchase, cart), customization depth, and the types of merchants it serves best.

We looked for apps that fit different business models and merchant preferences. The apps appear in an order that reflects general versatility first, followed by more specialized use cases.

Frequently asked questions

What is the difference between an upsell and a cross-sell?

An upsell suggests a more expensive or upgraded version of what the customer is buying. A cross-sell recommends a complementary or related product. Some apps specialize in one or the other; others handle both.

When should I use post-purchase upsells versus checkout upsells?

Post-purchase upsells appear after the order is confirmed and tend to convert well because purchase intent is highest. Checkout upsells occur during the buying process and may introduce friction. Both work depending on your product and audience.

Do I need a bundle app or can a regular upsell app handle bundles?

Regular upsell apps can suggest bundles, but apps built specifically for bundling offer more control over pricing, customization, and display. Choose a bundle-focused app if bundling is your main strategy.

How do I choose between these apps if I want both bundles and upsells?

Some apps like Kaching Bundles and Appstle handle both. Alternatively, you can use a bundle app for product grouping and a separate upsell app for recommendations at checkout or post-purchase.

Will multiple upsell apps conflict with each other?

Apps that target different moments in the checkout flow (cart drawer, checkout page, post-purchase) typically coexist without issues. Apps targeting the same location may conflict or duplicate offers, so test before enabling multiple apps at the same step.

How much revenue can I expect from upsell apps?

Results depend on your product type, customer base, offer quality, and implementation. Merchants should test offers and measure results specific to their store rather than relying on general benchmarks.
