Getting a customer to add one more thing to their cart is almost always cheaper than finding a new customer. That's the whole case for upselling on Shopify. A well-placed "frequently bought together" suggestion, a volume discount that nudges someone from one unit to three, or a post-purchase offer that catches a buyer while they're still in spending mode. When it works, it lifts your average order value without adding to your acquisition costs.
The tricky part is that "upsell app" covers a huge range of tools. Some focus on product page recommendations. Others target the cart drawer, the checkout, or the thank-you page. A few try to cover all four. And the pricing models vary just as much, from generous free plans to revenue-based fees that scale with your sales.
We've compared 10 of the most popular options for 2026, covering what each app actually does, where it works in the buying journey, what it costs, and where it falls short. Whether you want a full-funnel upsell engine or just a lightweight way to suggest related products on a product page, there's something here for you.
THE 10 BEST SHOPIFY UPSELL APPS
Selleasy — Best Overall
Selleasy is the best all-round upsell app on Shopify right now. It has a 4.9 rating from over 2,000 reviews, covers product page, cart, checkout, and post-purchase touchpoints, and the free plan includes every feature for stores doing up to 50 orders per month with no revenue share. That's genuinely hard to beat for a store just getting started with upselling.
The app recreates the Amazon-style "frequently bought together" experience, along with cart upsells, post-purchase offers, and related product recommendations. It supports multi-language and multi-currency stores, and the upsell widgets are embedded and unobtrusive rather than popup-based. Setup is straightforward, and the team offers free help via Zoom if you get stuck. For feature depth, ease of use, and pricing fairness, Selleasy sets the standard in this category.
Pricing: Free for up to 50 orders/month (all features included); paid plans from $8.99/month. Touchpoints: Product page, cart, checkout, post-purchase. Best for: Most Shopify stores, especially those wanting a complete upsell solution at a fair price.
Section Store — Best for Lightweight, Customisable Upsells
Section Store takes a different approach to upselling. Instead of an app that injects widgets through scripts, its upsell sections are native .liquid theme files that you install directly into your theme and customise in the Shopify Theme Editor. That means they load with the rest of your page, match your theme's design perfectly, and leave no leftover code if you remove them.
The $10/month Plus subscription includes upsell sections, volume bundles, quantity breaks, add-ons, Conversion Blocks (trust badges, sticky cart, countdown timers, payment icons), priority support, and AI agents. There's also the option to buy individual upsell-related sections as one-time $9 purchases if you'd rather not subscribe. Either way, no revenue commission and no percentage-based fees on your sales.
Section Store isn't trying to be a full-funnel upsell engine. It doesn't have AI product recommendations, post-purchase one-click offers, or checkout-level upsells. What it does well is give you total design control over how upsells look on your product pages and throughout your store, without adding another heavy app to your stack. If you already have a clear idea of which products to pair and you want the upsell to feel like a natural part of your theme rather than a bolted-on widget, this is the way to go.
Pricing: $9/section (one-time) or $10/month Plus for all upsell sections, bundles, and Conversion Blocks. Zero revenue commission. Touchpoints: Product pages, any page via Theme Editor. Best for: Merchants who want lightweight, native upsells with full design control and no recurring per-sale fees.
ReConvert — Best for Post-Purchase Upsells
ReConvert has carved out a strong niche in post-purchase upselling. It has a 4.8 rating from nearly 3,000 reviews and focuses on what happens after the customer clicks "Buy." One-click upsells on the thank-you page, post-purchase funnels, order tracking with embedded offers, and birthday-based re-engagement. The thank-you page builder alone is worth looking at if you're currently leaving that page blank.
The one-click upsell flow is smooth. Customers don't need to re-enter payment details, which removes the friction that kills most post-purchase offers. It's less useful if you need pre-purchase or in-cart upsells, but for stores that want to maximise revenue from completed orders, ReConvert is purpose-built for that job.
Pricing: Free for dev stores; paid plans from $4.99/month (usage-based pricing applies at higher tiers). Touchpoints: Post-purchase, thank-you page. Best for: Stores focused on squeezing more revenue from every completed order.
Essential Upsell & Cross Sell
Essential Upsell holds a perfect 5.0 rating from nearly 2,000 reviews, which is notable at that volume. It covers product page, cart, checkout (for Plus stores), and post-purchase upsells with frequently bought together bundles, BOGO deals, and automatic discount promotions. The setup is quick and beginner-friendly.
One thing to flag: the free plan caps upsell revenue at $100. Once you cross that, you're on a paid plan. The revenue-based pricing at higher tiers means your costs scale with your sales, which is the same model we flagged in our bundle apps comparison. Worth watching as you grow.
Pricing: Free plan (up to $100 upsell revenue); paid plans from $7.99/month with usage tiers. Touchpoints: Product page, cart, checkout, post-purchase. Best for: Beginners who want a polished upsell app with fast setup.
Aftersell — Best for Checkout & Post-Purchase (Shopify Plus)
Aftersell is built for stores that take their post-purchase and checkout upsell strategy seriously. It uses Shopify's native Checkout Extensibility to place upsell blocks directly inside the checkout flow, along with one-click post-purchase offers and thank-you page upsells. The A/B testing is strong, and the analytics attribute revenue per offer so you can see exactly what's working.
The catch is that it's really aimed at higher-volume merchants and Shopify Plus stores. The feature set reflects that, and so does the pricing. For smaller stores, Selleasy or ReConvert will give you more value at the early stages. But once you're doing significant volume and want granular control over checkout upsells with proper testing, Aftersell is hard to beat.
Pricing: From $34.99/month (scales with order volume). Touchpoints: Checkout, post-purchase, thank-you page. Best for: High-volume and Shopify Plus stores that need native checkout upsells with testing and attribution.
iCart — Best Cart Drawer Upsells
iCart replaces your standard Shopify cart with a slide-out drawer that has upsell capabilities built in. You can add product recommendations, progress bars (like "Add $15 more for free shipping"), discount codes, and countdown timers right inside the cart drawer. It has a 4.8 rating and the approach works well because it catches customers at the moment they're reviewing their order.
If your store doesn't already have a cart drawer and you want one with upsell built in, iCart is a two-for-one. If you already have a cart drawer you like, the integration might cause conflicts. Check compatibility with your theme before installing.
Pricing: Free plan available; paid plans from $12.99/month. Touchpoints: Cart drawer. Best for: Stores that want to upgrade their cart experience with embedded upsells and progress bars.
Bold Upsell
Bold has been in the Shopify app game for a long time, and Bold Upsell is one of their flagship products. It offers upsells on product pages, in the cart, at checkout, and post-purchase. You can build upsell funnels with multiple steps and configure upgrade-style offers ("Want the pro version instead?") alongside cross-sell suggestions.
The rating (4.3 stars) is lower than some of the newer competitors on this list, and reviews occasionally mention a dated interface. But the feature set is deep, and Bold's ecosystem of apps (Bold Subscriptions, Bold Memberships, etc.) can be an advantage if you're already using their other tools. For stores with complex upsell needs and a tolerance for a slightly older UI, it still holds up.
Pricing: From $9.99/month. Touchpoints: Product page, cart, checkout, post-purchase. Best for: Stores with complex upsell funnels or those already in the Bold ecosystem.
SellUp — AI-Powered Upsells
SellUp leans into AI-powered recommendations that work across the buying journey. It analyses your product catalogue and customer behaviour to automatically suggest relevant upsells. The app tracks revenue directly attributed to its recommendations (not total order value), so the ROI reporting is more honest than some competitors. Some merchants report ROI figures above 3,000%.
The review count is smaller than the top apps on this list (around 120), which means it's less battle-tested at scale. But if you have a large catalogue and don't want to manually configure every product pairing, the AI automation saves a lot of time.
Pricing: Free plan available; paid plans from $14.99/month. Touchpoints: Product page, cart, post-purchase. Best for: Stores with large catalogues that want AI to handle product pairing.
Fast Bundle
Fast Bundle is primarily a bundle app, but its cross-sell and frequently bought together features put it squarely in the upsell conversation too. It supports seven bundle types, automatic discount syncing, multi-currency, and analytics that track revenue per bundle. The "Built for Shopify" badge confirms it meets performance and integration standards.
Where it's weaker compared to a dedicated upsell app is on post-purchase and checkout offers. If your upsell strategy is mostly about recommending bundles and related products on the product page and in the cart, Fast Bundle handles that well. If you need post-purchase funnels or one-click checkout upsells, pair it with something like ReConvert.
Pricing: Free to install; paid plans from $19.99/month. Touchpoints: Product page, cart, collections. Best for: Stores where bundles are the primary upsell mechanism.
Vitals
Vitals comes up in every Shopify app comparison because it's 40+ marketing tools in a single $29.99/month subscription. Upselling is just one piece: it includes product bundles, volume discounts, recently viewed products, BOGO offers, and frequently bought together suggestions alongside reviews, email capture, currency conversion, and more.
The upsell features aren't as deep as a dedicated tool. You won't get the funnel sophistication of Selleasy or the post-purchase power of ReConvert. But if you're currently paying for four or five separate apps and want to consolidate, Vitals can cut your total app spend while still covering the basics of upselling.
Pricing: $29.99/month. No free plan; 7-day trial. Touchpoints: Product page, cart. Best for: Stores that want to consolidate multiple marketing tools (including basic upsells) into one subscription.

HOW TO THINK ABOUT CHOOSING
The "best" upsell app depends entirely on what part of the buying journey you want to optimise and how much control you want over the design.
If you want the most complete upsell app that covers every touchpoint with strong recommendations and fair pricing, Selleasy is the clear winner. It's the app we'd recommend to most stores as a starting point. The free plan is generous enough to prove out the concept, and the paid plans are reasonable once you're seeing results.
If your priority is keeping your store fast and your upsells looking like they were built into the theme from day one, Section Store is the better fit. Its upsell sections install as native theme files, which means zero external scripts, instant load, and full design control in the Theme Editor. You also get bundles, 730+ other theme sections, and Conversion Blocks for $10/month flat with no revenue cut. It's not a full-funnel upsell tool, but that's not what it's trying to be. It's the best option for merchants who want upsells to feel like a natural part of their theme, not a third-party widget sitting on top of it.
And if post-purchase is where you see the biggest opportunity, ReConvert is purpose-built for that. Plenty of stores run Selleasy or Section Store for pre-purchase upsells and pair it with ReConvert for the thank-you page. That combination covers the full journey without overlap or bloat.
CONCLUSION
Upselling doesn't need to be complicated. The apps on this list range from simple product page suggestions to full-funnel AI-powered engines, and the right choice depends on your store's size, budget, and where your customers are most likely to respond to an offer.
For most stores, Selleasy is the best place to start. It covers every touchpoint, the free plan is generous, and the pricing stays reasonable as you scale. For stores that want native theme integration, full design control, and no per-sale commission, Section Store offers something no other upsell app can match: upsell sections that are truly part of your theme, not bolted on top of it.
Try either one. Both have free options to get started, and you'll know within a week which approach works better for your store.
