Shopify Cart Upsell: Boost AOV & Sales Easily 2025

Introduction

Are you looking for a proven way to increase revenue without driving more traffic?

You need to start using Shopify cart upsells.

Cart upselling is one of the smartest ways to increase your Average Order Value (AOV). It works by recommending relevant products right before the customer checks out — when buying intent is highest.

In this guide, you’ll learn:

• What cart upsell is and why it matters
• How to set up cart upsell in Shopify
• Use cases for Shopify custom cart upsell
• How to enable upsell at checkout
• The best apps to automate upsells

Let’s convert those carts into bigger profits.

What Is Shopify Cart Upsell?

Cart upsell in Shopify is a strategy where you recommend additional products in the cart page or just before checkout.

This tactic encourages customers to add complementary or higher-priced items before completing their purchase.

Why Cart Upsell Works:

• High buying intent = high conversion rate
• It’s non-intrusive and helpful when done right
• You increase revenue per customer without extra ad costs

Example:

If someone adds a camera to their cart, upsell a memory card or camera case before checkout.

How to Set Up Cart Upsell on Shopify

There are multiple ways to implement cart upsells on Shopify — depending on your theme, budget, and goals.

Option 1: Use Shopify Built-In Features

Some Shopify 2.0 themes support upsell blocks on the cart page.

Steps:

1. Go to Online Store > Themes > Customize
2. Navigate to the Cart Page
3. Add a “Product Recommendations” block
4. Choose “You may also like” or “Frequently Bought Together”

Tip: These are based on purchase history and collection logic.

Option 2: Use Shopify Cart Upsell Apps

Using apps is the fastest and most flexible way to implement cart upsells.

Here are some top-rated apps for 2025:

App	Features	Free Plan
ReConvert	Smart cart upsell, thank-you page upsells	Yes
Zipify OCU	One-click upsell at checkout & cart	Yes
Frequently Bought Together	Cart & product page upsells	Yes
Honeycomb Upsell Funnels	Custom upsell funnels	Yes

These apps support both cart page and upsell at checkout placement.

Shopify Custom Cart Upsell (Advanced)

Want more control over what’s shown in the cart? You can build custom cart upsells using Shopify Scripts, Liquid, or Checkout Extensibility (for Shopify Plus).

Custom Cart Upsell Using Liquid:

In your cart-template.liquid or cart.liquid, insert this snippet:

liquid

CopyEdit

{% for product in collections.upsell.products %}

  <div class="upsell-item">

    <h4>{{ product.title }}</h4>

    <img src="{{ product.featured_image | img_url: 'small' }}">

    <form method="post" action="/cart/add">

      <input type="hidden" name="id" value="{{ product.variants.first.id }}">

      <button type="submit">Add to Cart</button>

    </form>

  </div>

{% endfor %}

This displays a set of upsell products pulled from a specific collection (upsell).

Upsell Logic Tips:

• Base upsells on cart contents (e.g., if cart has shoes, upsell socks)
• Use product tags or types to trigger relevant offers
• Keep the upsell UX clean and distraction-free

Shopify Upsell at Checkout

Upselling at checkout is a powerful strategy — especially with Shopify Plus or Checkout Extensibility.

You can recommend upgrades or add-ons after the cart page but before payment.

How to Enable:

For Shopify Plus:

1. Use Shopify Scripts in the Script Editor
2. Target upsells by cart content or price
3. Show dynamic offers in checkout

For Non-Plus Merchants:

Use apps like:

• Zipify OneClickUpsell (OCU)
• Cart Lock
• ReConvert

These apps work with the Shopify Checkout API to show upsells and cross-sells during checkout or post-purchase.

Real Examples of High-Converting Cart Upsells

Industry	Cart Upsell Strategy	Example

Electronics	Suggest warranty or accessories	Upsell a laptop sleeve or insurance
Beauty	Add travel-sized versions	Upsell mini versions at 50% off

Tips to Maximize Upsell Conversion Rates

Here’s how to make your cart upsells convert better:

Tip	Result
Show upsell after they add something to cart	Less intrusive
Limit to 1-2 relevant offers	Avoid choice overload
Use discounts or bundles	Add urgency
Display star ratings or reviews	Build trust
Make the Add to Cart button visible	Faster decision-making

Optimize Cart Upsell for Mobile

More than 70% of traffic on Shopify is mobile. Your upsells must work seamlessly on small screens.

Mobile Optimization Tips:

• Use vertical stacking for upsell products
• Buttons should be large and thumb-friendly
• Avoid popups that block cart buttons
• Use sticky bar upsells or slide-ins

Track Your Upsell Performance

Use these tools to track how your upsells are performing:

1. Shopify Analytics

• Go to Analytics > Reports > Conversion Funnel
• Track added upsell items and cart conversion

2. Google Analytics 4 (GA4)

• Set custom events like add_to_cart and upsell_click
• Create funnels to see where upsell drop-offs occur

3. App Analytics

Most upsell apps like ReConvert and Zipify show:

• Conversion rate per upsell
• Revenue from each offer
• A/B test results
