6 Best Upsell Apps for Shopify: Complete Guide for 2026

A customer finally lands on your website. They browse. They add to the cart. They’re this close to checking out. 

And every store owner thinks the same thing:

“What if they bought just a little more?”

That instinct to turn a good order into a great one? That’s upselling.

But the real challenge is knowing when and how to do it without annoying your customers. 

In this blog, we break down everything you need to know about upselling. Why it matters, how it works, and how the right apps can quietly boost your revenue while your customers happily spend more.

Why Upselling Is Critical for Shopify Growth?

Growth on Shopify is about making every visit count, and that happens through upselling. Here’s why upselling is crucial for businesses: 

Boosts Average Order Value

Upselling encourages customers to spend more per purchase by upgrading or adding relevant products to their cart. Instead of working harder to bring in more traffic, you increase revenue from the shoppers you already have. Even a small increase in AOV can make a noticeable difference to your bottom line over time.

Maximizes Marketing ROI

You’ve already invested in ads, SEO, and campaigns to bring visitors to your store. Upselling helps you extract more value from every click by converting buying intent into higher-value orders. It’s one of the smartest ways to grow without constantly increasing your ad budget.

Enhances Customer Experience

When done right, upselling feels like guidance. Showing customers better versions, useful add-ons, or smart bundles improves their shopping journey and helps them feel confident about their purchase.

Builds Brand Trust

Relevant recommendations show that your store understands your customers. That builds credibility, loyalty, and repeat purchases over time.

Best Places to Add Upsells in a Shopify Store

Upsells don’t work because you show more products. They work because you show the right product at the right moment. Each placement in your Shopify store taps into a different customer mindset. Here are some of the best places to place the upsells, along with their benefits:

Product pages: Influence buying decisions early

This is where customers are still comparing, exploring, and imagining using the product. Adding upgrades, bundles, or “frequently bought together” items here helps shape what they think is normal to buy. It increases perceived value and reduces hesitation by making choices feel easier and more complete.

Cart drawer/cart page: Increase order value right before checkout

At this stage, shoppers have already committed mentally. Showing relevant add-ons here works because they’re already in purchase mode. A well-placed upsell in the cart feels like a helpful reminder of “Oh right, I might need that too.” This is one of the highest-performing spots for boosting AOV.

Checkout (pre-purchase): Capture quick, low-friction add-ons

Customers here want to finish fast. If you keep offers simple and relevant, you can add last-minute value without slowing them down. This placement works best for small, no-brainer extras that don’t require thinking, like accessories, protection, or digital add-ons.

Thank-you page: Convert when trust is highest

At this stage, the payment has been made, and satisfaction is high. That’s why post-purchase upsells convert so well. Customers are more open to saying “yes” because there’s no risk left. One-click upsells here feel effortless and natural.

Email and WhatsApp follow-ups: Recover missed upsell opportunities

Not everyone says yes on the site. Follow-ups let you reintroduce products in a calmer, more personal environment. With WhatsApp, especially, it feels like a recommendation. This is perfect for restocks, refills, or products that make more sense after using the first purchase.

Customer account pages: Personalize repeat purchases

Here, you already know what the customer likes. Showing upgrades, refills, or complementary items based on past orders feels helpful. This placement builds long-term value by increasing LTV, not just AOV.

Order tracking pages: Upsell when attention is still high

Customers revisit this page multiple times. That repeated engagement makes it a powerful, underused upsell location. Offers here feel contextual: “While your order is on the way, you might like this too.”

How to Choose the Right Upsell App for Your Shopify Store

Not every upsell app is built the same. The right one should fit your store’s goals, your customers’ behavior, and how you want to grow revenue. Here are some factors to consider to pick the one best suited for you:

• Define your growth goal: Decide whether you want to increase average order value, improve product discovery, or boost post-purchase revenue. Your goal determines whether you need cart, checkout, or post-purchase upsells.
• Map your customer journey: Identify where shoppers hesitate or drop off most often. Some apps work best before checkout, while others shine after the order is placed.
• Evaluate customization flexibility: Look for apps that let you control design, placement, and targeting rules so upsells feel natural.
• Assess setup and usability: If you don’t have a dev team, go for an app with drag-and-drop builders and no-code workflows that are easy to manage day to day.
• Match the app to store size: Some tools are better for new stores, while others are built for high-volume brands with complex funnels. Choose what scales with you.
• Look for smart targeting features: AI-powered recommendations based on cart value, behavior, or product type drive higher acceptance rates.
• Test before you commit: Use free trials or lower-priced plans first, and track AOV, conversion rate, and the impact on upsell revenue.

How Flowcart Uses WhatsApp to Turn Conversations into Conversions

Upselling doesn’t always have to happen on your website. In fact, some of the highest-converting upsells happen inside conversations, when customers are already talking to your brand. That’s where WhatsApp becomes a powerful upsell channel.

With over 2 billion users globally, WhatsApp is where customers naturally ask questions, seek recommendations, and clarify doubts before making a purchase. Instead of pushing products through pop-ups and banners, WhatsApp lets you guide customers just like a good in-store salesperson would. 

This is the core idea behind WhatsApp conversational marketing: using real-time, two-way chats to recommend the right products at the right moment, in a way that feels personal, helpful, and human.

And this is exactly where Flowcart comes in.

Flowcart helps you run upsells, cross-sells, and follow-ups directly inside WhatsApp conversations. Instead of losing customers after checkout or through cart abandonment, Flowcart turns every message into an opportunity to increase AOV and build trust.

Here are some of its most useful features for upselling: 

• Smart Upsells Driven by Real Conversations: Flowcart doesn’t push random offers. Using AI-led segmentation and intelligent broadcast logic, it suggests relevant upgrades based on what customers are asking about, clicking on, or adding to their cart, so every recommendation feels timely and useful.
• ‍Buy Bigger, Without Leaving WhatsApp: With Flowcart’s built-in WhatsApp checkout, customers can complete purchases right inside the conversation. Fewer steps mean less drop-off and a higher chance they’ll say yes to bundles, add-ons, and premium versions.‍
• After-Sale Offers in the Same Chat Thread: Once an order is confirmed, Flowcart helps you continue the conversation with follow-up recommendations. You can suggest accessories, refills, or upgrades while the customer is still engaged and happy with their purchase.

By blending Shopify’s product system with the ease of WhatsApp messaging, Flowcart makes upselling feel natural instead of forced and turns conversations into consistent revenue.

Here’s what Purity Waweru, CEO of Tanj Curtains, shares about their experience working with Flowcart:

“Working with Flowcart completely transformed how we sell. Our transactions became faster, our engagement improved, and we built genuine relationships with customers. In just a few months, sales jumped by 40%, and every lead coming through Flowcart converted. It’s been a total game-changer.”
