The Top 8 Shopify Upsell Apps

Amazon has trained consumers to expect seamless upsell experiences like “frequently bought together” recommendations.

Shopify brands need to follow suit to stay competitive. 

The best time to upsell? Right when customers are already in buying mode—whether it's before checkout, in the cart, or immediately after purchase.

Done right, upsells convert between 10-20% of the time, increasing AOV by 9.74% on average.

The good news? Shopify has a stack of powerful upsell apps that automate this process and optimize for maximum conversions. 

Below is a curated list of some of the top-rated upsell apps (including free and paid options), along with key features, pricing, and what makes each stand out.

Final Thoughts: Boost AOV and LTV on Your Shopify Site (and Mobile App)

Each of these apps can help you boost sales, but the best choice depends on your store’s needs (pre-purchase vs post-purchase upsells, desired features, and budget). 

All the above are highly rated by Shopify merchants, so you can be confident in their effectiveness and support.

One important part to note: if you’re selling across your website and a mobile app, you need to keep in mind that not all these upsell apps will work in your mobile app.

Many Shopify mobile app builders have a limited number of integrations available, meaning that your mobile app may not be compatible with your choice of upsell app.

However, if you use MobiLoud to build your mobile app, you don’t have to worry about this.

MobiLoud doesn’t have the restrictions of other Shopify mobile app builders. We guarantee that all your site’s apps and features will work the same in your mobile app.

The upsell app you rely on to drive 10-20% more AOV? It’ll do the same in your mobile app.

WIth other app builders, it’s not possible to carry over all your site’s features to your mobile app, without extensive (and costly) custom development.

So, make your pick from the best upsell apps for Shopify listed above; and if you want to ensure that everything works smoothly in your mobile app, build it with MobiLoud.
