Short on time? Here’s the quick breakdown
Shopify in cart upsell helps you make the most of every sale by suggesting extra or related products right in your customer’s cart.
It’s simple, effective, and a smart way to boost your average order value.
I am sure you would have gone shopping for one thing and ended up buying a little more than you planned.
Maybe you walked in to buy a phone but left with a higher-end model, or you added a pair of shorts or trousers to your cart when you only meant to buy a T-shirt.
That’s exactly how an upsell works.
In this article, we’ll look at the best apps for Shopify in cart upsell. Pick the app that suits you best, install it, and watch your average order value grow.
The 7 best Shopify in cart upsell apps are:
When it comes to Shopify in cart upsell apps, there isn’t a one-size-fits-all solution. There are two ways in which you can achieve this.
- Shopify in cart upsell apps
- Cart drawer apps
Shopify in-cart upsell apps works smoothly with your theme’s existing cart drawer and allow you to show relevant upsell products directly to your customers.
This is one of the simplest and most effective ways to increase your store’s average order value without changing how your cart behaves.
Cart drawer apps, on the other hand, are slightly more expensive but come with advanced features like progress bars, rewards, and other gamified upsells.
These apps usually replace your theme’s cart drawer entirely, which means they may not be compatible with every theme.
If you’re happy with your current theme and want to show upsells based on product recommendations, bundles, or AI-driven suggestions, then an in-cart upsell app is the better choice.
But if you’re not satisfied with your theme’s default cart drawer and want a completely upgraded, feature-rich slide cart experience, then a dedicated cart drawer app will be a better fit.
Every store is different, and so are its needs. That’s why I tested these apps myself - to help you understand what each one does well and to make it easier for you to choose the app that fits your store perfectly.

NEW - Selleasy AI (powered by ChatGPT)
This is the feature that truly sets Selleasy apart now.
The app doesn’t just recommend products - it also writes high-converting upsell pitches for you using AI.

Cart progress bar for gamified upsells
The progress bar is one of my favorite features. As customers add more items, the bar keeps moving toward rewards like free shipping or discounts. It feels like a game and naturally motivates shoppers to increase their cart value.
Volume discount nudges that convert
The volume discount message on the cart is a small touch, but it’s powerful. It reminds customers that adding just one more item unlocks a better deal - and that nudge often results in a bigger order.

If you want to pick the best Shopify in cart upsell app, here are the top features you should look for:

Look for an app that lets you customize fonts, colors, styles, and layout so the upsell offer looks like a natural part of your store.

AI-powered upsell suggestions can make a huge difference.
Pick an app that can automatically recommend products based on the customer’s cart, behavior, or purchase history. It saves time and increases conversions.

A good upsell app should let you set conditions such as cart value, cart total, or specific product triggers.
This ensures your upsells are relevant and don’t feel random to the customer.
