Increasing your average order value (AOV) without spending a dime on extra traffic? Yes, please! That’s where cart upsell apps come in. 

In 2025, Shopify's app ecosystem is packed with powerful tools designed to help you strategically nudge customers toward higher-value purchases, right at the cart. From AI-powered product recommendations to personalized discounts and irresistible bundle offers, we’ve rounded up the 10+ best cart upsell apps that can turn your cart page into a conversion goldmine. Let’s dive in.

What is Cart Upsell?

A sales tactic known as "cart upsell" involves offering a consumer extra goods or services at the time of checkout, usually in an online store.  By showcasing items that potentially enhance their existing cart, we hope to entice clients to make larger purchases. As an example, when a person is looking to buy a phone, a cart upsell can suggest choosing a case or screen protector as well.

Since the user is likely to buy, the suggestion shows them personalized items with offers like discounts or free delivery. It is different from cross-selling, where you promote products that are closely connected, and upselling, where you suggest increasing the level of what is being purchased. Suggesting extra products within the upsell only works when it’s relevant to the user’s cart, is well-timed, and feels easy.

Why your store needs a Cart Upsell App

A Cart Upsell App is more than just a sales tool; it’s a strategic asset that can elevate your eCommerce game by increasing revenue, enhancing customer experience, and driving repeat business.

• Boosts Average Order Value (AOV): A well-timed upsell offer can transform a $30 order into a $50 sale. Without requiring extra marketing work, a cart upsell software can encourage users to spend more by recommending related add-ons or complementing products at checkout. 
• Leverages Purchase Intent: At checkout, offer bundles, warranties, or time-limited deals. Smart upsells here can boost order value by convincing customers to add more just before they complete their purchase.
• Improves Customer Experience: Presenting matching accessories, such as a suitable charger for a customer’s new phone, results in better sales and helps shape a positive feeling towards the brand.
• Automates Personalization: Looking for upsell opportunities by hand takes a lot of time and may not be successful. Cart upsell apps look through customer behavior, their shopping carts, and past orders to recommend items that might interest them. 
• Reduces Cart Abandonment: Use upsell apps to offer discounts, free shipping, or limited-time deals at checkout, when customers are most focused, to boost conversions and win over hesitant buyers.
• Seamless Integration: Most cart upsell apps are made to be installed easily on leading eCommerce sites such as Shopify, WooCommerce, and Magento. They feature multiple user-friendly functions that complete your order with ease and do not bother the user during checkout.
• Data-Driven Insights: Being aware of what leads to an upsell and what doesn’t is how you can adapt your strategy. With the help of a cart upsell app, you can analyze how your offers perform and improve them over time.

Types of upsell apps

Upsell apps come in various formats, each serving a distinct purpose in the customer journey. Here are the key types:

• In-Cart Upsells: Apps use this opportunity to display extra related products or upgrades to customers. People buying products are more likely to add on additional items because of this choice.
• Post-Purchase Upsells: After the customer purchases, he or she is shown post-purchase upsells. Often, these offers add free products, briefly available bargains or monthly subscription services.
• Cross-Sell Pop-Ups: Cross-sell pop-ups suggest related products based on the customer’s cart contents or browsing history. These offers can appear during browsing, at checkout, or post-purchase.

Every kind of upsell app plays a special role in helping businesses get more sales during the customer journey. Properly managing merchandising and pricing can make a big difference in store earnings.

What to Look for in a Shopify Upsell App & How to Choose One

What to Look for in a Shopify Upsell App

Choosing the right upsell app can significantly impact sales, conversion rates, and the overall shopping experience. Here are key factors to consider:

• Types of Upsells Offered: Check if the app lets you set up offers before purchase, during checkout, right after, on the thank-you page and for upsells. Every sales force model helps the company grow its earnings in specific ways.
• Customization & Branding: Look for apps that allow customization to align with your store’s branding, ensuring a consistent shopping experience across all touchpoints. 
• Ease of Use & Setup: Pick apps that have clear design and do not require writing codes for fast construction. Technical options allow for advanced tools but developers might need to be involved.
• Targeting & Segmentation Capabilities: A good upsell app helps merchants sort customers by sales history, items left in the cart or the data they have stored, providing appropriate offerings based on that information.
• A/B Testing: A/B testing capabilities enable merchants to test different offers, formats, and placements to identify the most effective upsell strategies.
• Analytics & Reporting: You need to rely on data to find out how well the campaign is doing and how much return it brings. Opt for applications that give detailed reports on upsell performance.
• Integration with Other Shopify Apps: Ensure compatibility with essential apps like email marketing tools, review platforms, and loyalty programs to maximize upsell opportunities.
• Mobile Responsiveness: Because e-commerce is mainly through mobile devices, every aspect of the app should be made for mobile use.
• Pricing & Value for Money: Evaluate pricing plans, free trials, and overall ROI. Some apps offer free tiers or cost-effective plans for small businesses.
• Customer Support: Rapid resolutions depend on having reliable support. Select platforms that aid you at any time with good customer support, a large help center or live chats.

By looking at these factors, retailers may choose an upsell app that best suits their needs in terms of budget, preferences, and plans to boost sales and customer happiness.

Choosing the Right App for YOUR Store

• Step 1 - Assess Your Specific Needs: Determine what type of upsells align with your store’s strategy. Are you focusing on post-purchase funnels, in-cart offers, or product bundles?
• Step 2 - Consider Store Size and Product Range: Larger stores with diverse product catalogs may benefit from apps with advanced segmentation and targeting features.
• Step 3 -  Analyze Compatibility: Check that the app is fully connected to your current tech tools such as your email system, CRM and review platform.
• Step 4 - Compare Pricing Plans and Trials: Explore free plans or trial periods to test app functionality without an upfront commitment.
• Step 5 - Read User Reviews and Case Studies: The opinions and suggestions from users can give important information about the app, support and how much it costs.

By aligning app features with business needs, store size, and budget, merchants can effectively select a Shopify upsell app that maximizes sales potential while maintaining a smooth shopping experience.

Implementing Your Upsell Strategy with Your Choice

To have a successful upsell strategy, you need to choose an app, but you also must strategize where to put the offers, monitor how well they work and improve your tactics based on collected data. You can follow this step-by-step guide with practical strategies, real samples and insights from myself:

1. Identify Strategic Upsell Points

Before Purchase

In-cart upsells can prompt customers to add complementary items before they proceed to checkout. This is effective for increasing average order value without being too intrusive.

• Example: A clothing store using EcomRise: Upsell & Bundles could recommend a matching scarf or belt while the customer is viewing a specific product. This aligns with their current shopping intent and encourages additional spending.

Post-Purchase

Post-purchase upsells tap into the excitement of a completed purchase by offering additional products at a discount or suggesting future purchases. This can increase lifetime value without pressuring the buyer during checkout.

• Example: A skincare brand using ReConvert might offer a 20% discount on a complementary serum right after a moisturizer is purchased. This not only increases order size but also reinforces brand value.

Thank You Page Offers

Utilize the thank you page to suggest exclusive deals or upcoming promotions. This can be especially effective for encouraging repeat purchases.

• Personal Insight: From experience, I’ve seen thank you page offers work exceptionally well for subscription-based products, such as meal kits or beauty boxes. The key is to maintain a tone of appreciation while subtly nudging the customer towards the next purchase.

2. Leverage Personalization and Targeting

Segmentation

If you offer upsell to clients based on their prior purchases or what is in their shopping cart, you may significantly raise your upsell conversion rate.

Dynamic Product Recommendations

Implement AI-driven recommendations based on browsing behavior, previous purchases, or popular items.

3. Optimize Offer Placement and Timing

Strategic Placement

The timing and location of upsell offers matter. While in-cart and post-purchase upsells have proven effective, it’s crucial to avoid overwhelming the customer with too many pop-ups or offers at once.

• Personal Insight: Testing different placements (e.g., slide-out cart vs. popup vs. embedded offer) can reveal which format works best for your audience. In my experience, slide-out carts tend to be less disruptive than pop-ups while still catching the customer’s attention.

4. Monitor Performance and Adjust Strategies

A/B Testing

Utilize A/B testing to determine which offers, products, or discount levels drive the highest conversions.

• Example: A jewelry brand using In Cart Upsell tested a 10% discount versus a $5 flat discount on complementary items. Surprisingly, the flat discount outperformed the percentage discount by 22%, demonstrating that specific monetary values can feel more tangible to customers.

Analyze Data

Regularly review upsell performance through analytics dashboards. Track metrics such as conversion rates, AOV lift, and cart abandonment to refine strategies.

• Personal Insight: From previous projects, I’ve learned that monitoring upsell performance at least biweekly allows for timely adjustments. If a specific offer is underperforming, consider testing new product pairings or adjusting the discount.

5. Integrate with Existing Marketing Efforts

Email Marketing

Sync upsell apps with email marketing platforms to follow up with customers who did not accept the initial upsell offer.

• Example: A beauty brand could send a post-purchase email highlighting the benefits of the product the customer viewed but didn’t buy, coupled with a time-sensitive discount.

SMS and Push Notifications

Send SMS or push notifications to inform customers whenever there are short-term deals or things they might want that are back in stock. Customers are more likely to accept post-purchase upsells because this strategy isn’t too pushy.

• Personal Insight: In my experience, SMS works particularly well for time-sensitive offers (e.g., “Your cart is still waiting—add [Product X] and save 15% now!”). The key is to keep the messaging concise and actionable.

Frequently Asked Questions

1. Are cart upsell apps worth it for small Shopify stores?

Such apps definitely help small Shopify stores grow their sales and AOV without spending extra on marketing. Sometimes a small amount of traffic helps, as customers can be prompted to get similar items and increase your income. A lot of apps have low-cost plans and free trials which makes them reachable for small businesses.

2. Can I use multiple cart upsell apps simultaneously?

Yes, but it’s generally not recommended. Running multiple upsell apps can lead to overlapping offers, a cluttered checkout experience, and potential app conflicts. Instead, choose one comprehensive upsell app that covers multiple strategies, like in-cart, post-purchase, and thank you page upsells.

3. What’s the best way to measure the success of a cart upsell app?

Keep an eye on the average order value (AOV), upsell conversion and the revenue coming from upsells. Use the app’s analytics dashboard to monitor performance, run A/B tests to refine offers, and compare before-and-after sales data to assess impact.

4. Do cart upsell apps slow down my Shopify store?

Some apps can affect load time, especially those with heavy scripts or multiple widgets. To prevent this, choose apps known for optimized performance, use only essential features, and regularly monitor your store’s speed using tools like Shopify’s speed report.

5. Are there any free cart upsell apps for Shopify?

Yes, several cart upsell apps offer free plans or trials, such as Corner Free Gift & Cart Upsell and Monk Free Gift+BOGO+CartUpsell. These options are great for small stores to test upsell strategies without upfront costs.

Final Thoughts

Getting the right upsell app for your Shopify store can boost sales while requiring very little work from you. The right app can improve sales and the way your store runs, all without requiring you to spend on more marketing. Because of this, try each of these approaches, keep experimenting and watch your sales increase automatically!
