Looking for the best Shopify upsell apps to raise your average order value in 2026?

This guide ranks the 8 best Shopify upsell apps for 2026, with honest pricing, real ratings, where each one is strongest, and where it falls short, so you can pick the right one for your store size and goal without wasting money on apps that slow your store down.

Upselling is the cheapest way to lift average order value you will ever find, because you are not paying for an extra click to earn it. The right upsell app asks "want to add this?" for you, automatically, on every single order, without the pushy pop-ups that make shoppers close the tab. The catch is that the App Store has hundreds of apps claiming to do this, and many "top 10" lists are just affiliate link farms. So we tested the ones that actually matter, sorted them by where they work best, and wrote down the real trade-offs. Here are the eight worth your time in 2026.
Quick comparison: 8 Shopify upsell apps at a glance
Scores are editorial, from reviewing each app's listing, plans and features against the same checklist (see how we picked). Ratings and prices are from the Shopify App Store on September 24, 2026.

What is the best Shopify upsell app?
TL;DR: Webrex: Upsell & Cross Sell is our pick for most stores in 2026. It now covers the product page, cart, cart drawer, checkout and the Thank You and Order Status pages from one app, lets you decide exactly which products get recommended where and to whom, and matches your brand instead of dropping in a generic widget, from free up to $49.99 a month. Selleasy is the best value if you do well over 500 orders a month and want the lowest flat price. ReConvert is the best thank-you page tool, and AfterSell is the pick for Shopify Plus checkout upsells with A/B testing. Disclosure: we build Webrex, and the cons on its card are real.

Webrex scores 9.3, ahead of Selleasy at 9.1 and ReConvert at 8.8.
Webrex ranks first for stores that want every touchpoint covered with full control over the offer. Selleasy is the best value at high volume. Five reasons, each with a caveat.
It covers every touchpoint. Product page, cart, cart drawer, popup, sticky bar, checkout, and the Thank You and Order Status pages, all from one app. Caveat: offers inside the checkout steps need Shopify Plus, as they do for every app here.
You control the recommendations. Set rules by collection, vendor, product type or tag and target any page, so a brand's collection page shows only that brand's accessories. Selleasy's listing does not list custom rules.
It targets the right shopper. Customer-based targeting, country-based discount rules, automatic local currency pricing and labels auto-translated into 16+ languages.
It looks like your store. Multiple layouts, 5+ free templates and full CSS, running on your theme's native cart with no page refresh. Caveat: A/B testing is not listed, so if you want to split-test offers, look at ReConvert, AfterSell or Honeycomb.
Merchants rate it highest. A perfect 5.0 from 133 reviews, 96% of them five stars, and the Built for Shopify badge. Caveat: Selleasy has 2,717 reviews, a far longer record.
If you already do 1,000+ orders a month and price matters most, Selleasy. If your thank-you page is blank, ReConvert. If you are on Shopify Plus and want to test checkout offers, AfterSell.
What Shopify upsell apps cost
Four of the eight have a free plan for live stores (Webrex, Selleasy, ReConvert and Honeycomb). Order-based flat tiers run $9 to $80 a month for most stores; ReConvert's top tiers, Honeycomb's view-based pricing and Zipify's revenue-based pricing climb higher as you grow.
The cheapest app is not always the cheapest outcome. An app that slows your store or shows the wrong product costs more in lost conversions than it saves.
First, the three places a Shopify upsell app works
Before you pick an app, it helps to know that upselling happens in three different spots, and most apps are strong in one and weak in the others.
The cart is where a shopper has already committed to something and is open to adding more. Think "frequently bought together" blocks, a slide-out cart drawer with add-ons, or a free-shipping progress bar that nudges them to spend a little more.
The checkout is the highest-intent moment there is. Wallet is out, decision is made. A well-placed one-click add-on here converts better than almost anywhere else, though full checkout upsells built through checkout app extensions are mostly a Shopify Plus feature.
The post-purchase thank-you page is the sneaky-good one. The order is already done, so a one-click offer here carries zero risk of hurting your main conversion rate. If they say no, you have lost nothing. If they say yes, it is pure profit.
The best setup usually blends all three, so the strongest upsell app for Shopify is the one that covers the spot you care about most without slowing the others down.
Where each app upsells
✓ = listed as a feature on the app's Shopify App Store page on September 24, 2026. Not listed = not itemized on the listing.
| App | Product page | Cart / drawer | Checkout | Thank-you page | Custom rules | A/B testing | Free plan |
|---|---|---|---|---|---|---|---|
| Webrex | ✓ | ✓ | ✓ | ✓ | ✓ | Not listed | ✓ |
| Selleasy | ✓ | ✓ | ✓ | ✓ | Not listed | Not listed | ✓ |
| ReConvert | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ |
| AfterSell | ✓ Yes (Pre-Purchase) | ✓ | ✓ | ✓ | ✓ | ✓ | Dev stores |

| Zipify OCU | ✓ | ✓ | ✓ Yes (Plus) | ✓ | ✓ | ✓ | Dev stores |
| Candy Rack | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | Trial only |
Where Webrex wins: it pairs every touchpoint with rule-based, customer and country targeting and full CSS design control, starting on a free plan. Where it does not: apps built around split testing (ReConvert, AfterSell, Honeycomb, Zipify) go further if testing offers is your main job.
How we picked the best Shopify upsell apps
We did not rank by review count alone, because a big number next to five stars tells you an app is popular, not that it fits your store. Instead, we looked at four things: where the app actually works in the funnel, whether it slows your store down (page speed quietly kills conversions), how honest the pricing is once you scale, and how much setup pain you are signing up for.
Each app gets an editorial score out of 10, weighted on touchpoint coverage (x3), control over what is recommended and to whom (x2), speed and design fit (x2), pricing as you scale (x2), and rating and support (x1).
We also kept the list at eight on purpose. A tidy "top 5" or a bloated "top 20" usually means someone is padding for links. Eight is enough to cover every use case and store size without recommending apps we would not install ourselves.
Disclosure: the first app is ours. We build Shopify apps, and this is one we are proud of, so it earns the top spot on merit, and we will tell you exactly where it fits and where it does not. Everything after it is a genuine competitor we would happily recommend.
Webrex: Upsell & Cross Sell
Best overall: every touchpoint, with you in control of what gets recommended
Rating: 5.0 / 5 (133 reviews)
Best for: Stores that want every touchpoint covered and full control over which products get recommended, where, and to whom, in one fast app that matches their brand.
Webrex: Upsell & Cross Sell now covers every place an upsell can happen: the product page, cart, cart drawer, checkout, and the Thank You and Order Status pages. You can build Frequently Bought Together bundles based on what people actually buy together, run Buy X Get Y offers, add popup and sticky upsells, and show AI recommendations with smart filters that stay relevant instead of recommending random junk.
The reason it takes the top spot is control. Most upsell apps auto-pick products and bolt a generic widget onto your theme. Here you set the rules: recommend by collection, vendor, product type, or tag, and target any page, so a brand's collection page can show only that brand's accessories. You can target offers by customer and by country, set country-based discount rules, and prices and discounts convert to the shopper's local currency automatically. Offer labels auto-translate into 16+ languages. And every widget matches your design, with multiple layouts, 5+ free templates, and full CSS control, instead of the plain default styling you end up fighting in other apps.
What we hear most from merchants is that it does not tank page speed. It runs through Shopify's Checkout Extensibility and works with your theme's native cart, with no page refresh, rather than bolting heavy scripts onto every page, so the offers show up without the layout jump that makes some bundle apps feel clunky. You also get a free-shipping spending goal in the cart drawer with discount boosters, and a real-time attribution dashboard so you can see which offers earn their keep.
It carries a perfect 5.0 rating from 133 reviews (96% of them five stars, with merchants singling out the support team for making custom changes to fit their store) and holds Shopify's "Built for Shopify" badge, the platform's own quality bar.
Pricing: Free up to 50 orders per month, then flat tiers from $9.99/mo with a 14-day free trial. No revenue share, and 30% off on yearly billing.
| Plan | Monthly Price | Best For |
|---|---|---|
| Free | Free | New stores up to 50 orders/mo: product, cart and drawer upsells, bundles, BxGy, AI recommendations, rule targeting |
| Starter | $9.99/mo | Small stores up to 100 orders/mo adding Thank You and Order Status page upsells, local currency pricing, onboarding call |
| Growth | $19.99/mo | Growing stores up to 200 orders/mo wanting popup and sticky upsells, customer targeting, auto-translate, free shipping goal |
| Scale | $49.99/mo | Established brands up to 500 orders/mo adding checkout page upsells and a custom design built for them |
Where it is not the pick: It is newer than Selleasy, so it has far fewer reviews, and if you do well over 500 orders a month on a tight budget, Selleasy's flat $29 top tier is cheaper. If your whole strategy is one-click post-purchase funnels with A/B testing, a dedicated tool like ReConvert or Zipify goes deeper there. For most stores that want control over what gets recommended and offers that look like their own brand, though, this is the one we would install first.
Pros
- Rules by collection, vendor, type and tag, on any page
- Customer and country targeting, local currency, 16+ languages
- Brand-matched widgets: layouts, templates and full CSS
- 5.0 rating, 96% of reviews five stars
Cons
- 133 reviews, a much shorter record than Selleasy
- A/B testing is not listed as a feature
- Top plan covers up to 500 orders a month
You can install it for free on Shopify and have your first bundle live in minutes.
Selleasy
Best value: every touchpoint at the lowest flat price
Rating: 4.9 / 5 (2,717 reviews)
Best for: Stores that want every touchpoint covered on a tight budget.
If you want one app that touches the product page, cart, checkout, and post-purchase all at once, Selleasy is the best-value all-rounder on the store. It sits at a 4.9 rating across more than 2,700 reviews, and the reason people love it is the free plan, which includes every feature for stores doing up to around 50 orders a month, with no revenue share skimmed off the top.
The other standout is support. Selleasy will hop on a video call and set the whole thing up for you, which is rare at this price. For a high-volume store that wants coverage everywhere at the lowest flat price, it is hard to beat.
Pricing: Free up to roughly 50 orders per month, then affordable flat tiers. No revenue share.
| Plan | Monthly Price | Best For |
|---|---|---|
| Starter Tier I | Free | New stores up to 50 orders/mo testing every touchpoint, no revenue share |
| Starter Tier II | $9/mo | Small stores up to 500 orders/mo wanting all 18 upsell strategies |
| Starter Tier III | $19/mo | Growing stores up to 1,000 orders/mo scaling upsells |
| Starter Tier IV | $29/mo | Established stores doing 1,000+ orders/mo |
Watch out for: Recommendations are mostly automatic, with less control over exactly which products show on which page or to which customers. The interface tries to do so much that it can feel busy at first, and the default widget styling is a little plain, so plan on some tweaking to match a premium theme.
Pros
- 4.9 from 2,717 reviews, the longest record here
- All 18 strategies on every plan
- $29 flat covers 1,000+ orders a month
Cons
- Custom targeting rules are not listed as a feature
- Default widget styling is plain
- Busy interface at first
Upsell.com (ReConvert)
Best for the thank-you page
Rating: 4.8 / 5 (3,092 reviews)
Best for: Squeezing more from the thank-you page.
ReConvert built its name as the post-purchase and thank-you-page specialist, and it is still the sharpest tool for that job. Sitting near a perfect rating across thousands of reviews, it gives you a drag-and-drop editor to turn the boring default order-confirmation page into a second storefront: one-click upsells, reorder prompts, birthday collectors, and surveys that feed your segmentation.
Because these offers fire after the sale is locked in, there is no downside risk to your conversion rate. That makes ReConvert one of the safest ways to add revenue you are currently leaving on the table.
Pricing: Free up to 50 orders or $50 in upsell revenue, then $9.99 per month up to 2,000 monthly orders or upsell revenue, whichever is higher. Cheap to start, though you will want to do the math once volume climbs.
| Plan | Monthly Price | Best For |
|---|---|---|
| Free | Free | New stores up to 50 orders or $50 upsell revenue |
| Growth | $9.99/mo | Stores up to 2,000 monthly orders or upsell revenue |
| Scale | $199/mo | Higher-volume stores up to 10,000 orders or upsell revenue |
| Elite | $499/mo | Large stores up to 20,000 orders or upsell revenue |
Watch out for: Billing counts your orders or upsell revenue, whichever is higher, and the jump from $9.99 to $199 past 2,000 is steep, at which point a flat-fee app can work out cheaper.
Pros
- Deepest thank-you page editor
- A/B testing and segmentation on every plan
- Free up to 50 orders
Cons
- Billing counts orders or upsell revenue, whichever is higher
- Jumps from $9.99 to $199 past 2,000
- Strongest on the page after checkout, not before it
AfterSell
Best for Shopify Plus checkout upsells
Rating: 4.8 / 5 (1,055 reviews)
Best for: Shopify Plus and higher-volume stores that want true checkout upsells.
AfterSell leans into the checkout itself, which is where Shopify Plus merchants have the most room to play thanks to checkout extensibility. You get one-click post-purchase offers, customizable thank-you pages, and, on Plus, upsells injected right into the checkout flow, plus built-in A/B testing so you can prove what actually lifts average order value instead of guessing.
The pricing model is the real differentiator here. AfterSell charges a flat monthly fee with no revenue share, so once you are doing serious volume, it often works out cheaper than commission-based rivals. It even carries a 30-day ROI guarantee.
If you are cleaning up more than just the upsell, our guide to Shopify checkout customization covers the rest of the settings worth revisiting at the same time.
Pricing: Starts at $34.99 per month with a 30-day free trial, no revenue share.
| Plan | Monthly Price | Best For |
|---|---|---|
| Development Stores | Free | Development and partner stores only |
| Post-Purchase | $34.99/mo | Stores adding one-click post-purchase, checkout and thank-you page offers |
| Pre-Purchase | $59.99/mo | Stores wanting AI cart building, product page upsells, rewards bars and A/B testing |
| Complete | $79.99/mo | Stores wanting both plus the product recommendation engine |
Watch out for: The entry price is steep for a brand-new store, and the strongest checkout features only unlock on Shopify Plus. If you are on a basic plan doing low volume, you are paying for headroom you cannot fully use yet.
Pros
- Flat fee, no revenue share
- A/B testing built in
- Post-purchase, checkout and cart in one Complete plan
Cons
- No free plan for live stores
- Best checkout features need Shopify Plus
- Full coverage costs $79.99
Honeycomb Upsell & Cross Sell
Best for split-tested upsell funnels
Rating: 4.6 / 5 (161 reviews)
Best for: Stores that want data-backed upsell funnels with built-in split testing.
Honeycomb, from the Conversion Bear team, is the closest thing to a personalization engine that a normal store can actually run without a developer. It builds true one-click upsell and downsell funnels across pre-purchase, in-cart, and post-purchase, and its standout feature is native A/B testing, so you are proving which offer lifts average order value instead of guessing. It leans on order and product data to auto-suggest what to show, which keeps offers relevant as your catalog grows.
Sitting at a solid rating, it is the pick for a store that has outgrown simple "add this too" offers and wants to treat upselling like a testable system, without jumping to enterprise pricing.
Pricing: Free plan to start, with paid tiers that scale by upsell revenue and order volume.
| Plan | Monthly Price | Best For |
|---|---|---|
| Free | Free | New stores testing upsell funnels, up to 100 funnel views/mo |
| Silver | $54.99/mo | Small stores up to 2,000 funnel views, branding removed |
| Gold | $109.99/mo | Growing stores up to 5,000 funnel views |
| Platinum | $169.99/mo | Higher-traffic stores up to 10,000 funnel views |
Watch out for: The funnel and testing depth mean a steeper setup than the plug-and-play apps, and once your upsell volume is high, the revenue-based tiers are worth doing the math on against a flat-fee rival.
Pros
- Native A/B testing
- One-click upsell and downsell funnels
- Free plan to start
Cons
- Priced by funnel views
- Checkout upsell is not listed
- Steeper setup than plug-and-play apps
UpCart
Best cart drawer
Rating: 4.7 / 5 (942 reviews)
Best for: Stores whose whole upsell strategy lives in the cart drawer.
UpCart is a cart-focused specialist. It builds a slick slide-out cart drawer and packs it with the things that lift average order value at that exact moment: in-cart upsells, add-on suggestions, a free-shipping progress bar, rewards, and announcement rows. If you have decided the cart is your battleground, this app owns that ground.
Pricing: Paid plans start around $29.99 per month with a 14-day trial.
| Plan | Monthly Price | Best For |
|---|---|---|
| Development Stores | Free | Development and partner stores only |
| 0-200 Orders | $29.99/mo | New stores building a converting cart drawer |
| 201-500 Orders | $34.99/mo | Growing stores scaling in-cart upsells and rewards |
| 501-1000 Orders | $54.99/mo | Mid-volume stores wanting full cart customization |
Watch out for: It is deliberately narrow. There is no post-purchase or deep checkout play here, so if you want coverage beyond the cart, you will be pairing it with something else, and there is no free tier to grow into.
Pros
- Polished slide-out cart drawer
- Progress bar, rewards and sticky cart
- Custom rules and CSS
Cons
- Cart only, no checkout or post-purchase
- No free plan for live stores
- You will pair it with another app for full coverage
One Click Upsell (Zipify OCU)
Best for funnel builders who want to pay on results
Rating: 4.6 / 5 (564 reviews)
Best for: Merchants who want to build proper upsell funnels with A/B testing.
Zipify came out of the Ezra Firestone school of direct-response ecommerce, and OCU reflects that. It is built for pre-purchase and post-purchase one-click funnels, with a real funnel builder, split testing, and an AI autopilot that can pick the best offer for you. If you think in terms of funnels and want to test offers scientifically rather than set-and-forget, this is your app.
Pricing: Starts at $9.95 per month and steps up with the upsell revenue it earns you, never with order volume, capped at $999 per month.
| Plan | Monthly Price | Best For |
|---|---|---|
| Development Stores | Free | Dev and partner stores, includes all paid features |
| Upsell up to $200 | $9.95/mo | Stores earning up to $200/mo in upsell revenue |
| Upsell $200-2,500 | $25-$99/mo | Stores earning $200 to $2,500/mo in upsell revenue |
| Upsell $2,500+ | From $149/mo | High earners, price steps up with revenue to a $999 cap |
Watch out for: The depth is also the downside. There is a learning curve, and the price is hard to justify for a store that just wants a single "add this too" offer rather than a full funnel operation.
Pros
- Priced on upsell revenue, never order volume
- AI upsells and A/B testing
- In-checkout upsells on Shopify Plus
Cons
- Learning curve
- Price climbs with success, up to $999
- No free plan for live stores
Candy Rack
Best for one-click add-ons like warranties and gift wrap
Rating: 4.9 / 5 (261 reviews)
Best for: Clean, one-click add-on offers across the whole journey.
Candy Rack, from the Digismoothie team, is the polished all-in-one that keeps things simple. It shows one-click offers from the product page through cart, checkout, and post-purchase, with ready-made templates for cross-sells, service add-ons (think warranties or gift wrap), and gifts. Its Smart Auto-Upsell mode leans on Shopify's own AI to pick a relevant product so you do not have to build every offer by hand.
Pricing: Free for trial and development stores, with paid tiers from $29.99 per month scaling by orders.
| Plan | Monthly Price | Best For |
|---|---|---|
| Trial & Dev | Free | Trial and development stores only |
| Lite | $29.99/mo | New stores up to 50 orders/mo, one-click offers plus slide cart |
| Starter | $39.99/mo | Small stores 51-200 orders/mo |
| Growth | $59.99/mo | Growing stores 201-500 orders/mo |
Watch out for: The paid tiers climb fairly quickly as your order count grows, so keep an eye on which bracket you land in.
Pros
- Ready-made warranty, gift wrap and gift templates
- Smart Auto-Upsell picks products for you
- 4.9 from 261 reviews
Cons
- No free plan for live stores
- Price climbs by order count
- Less control over targeting than rule-based apps
How to choose the right upsell app for Shopify
Forget the ratings for a second and answer one question: Where do you want to make the offer? That answer, more than any star rating, tells you which upsell app for Shopify is right for you. Shopify's built-in assistant can set up a basic discount, but Sidekick can't build a cross-sell funnel, which is the job these apps do.
If you are a newer store and want coverage everywhere for as close to free as possible, start with our Webrex app, or Selleasy if you already do well over 500 orders a month and budget is the priority, and grow into the paid tiers. If your thank-you page is a wasted blank space right now, add ReConvert, since it carries no risk to your main funnel. If you are on Shopify Plus doing real volume, AfterSell's flat pricing and checkout upsells will likely pay for themselves. And if you have outgrown simple offers and want to prove which upsell actually lifts AOV, Honeycomb's split testing is the graduation.
Whatever you pick, install one app at a time and actually watch the numbers for two weeks before adding another. Stacking three upsell apps at once is the fastest way to slow your store down and confuse your shoppers, which costs you more than the upsells earn.
Frequently asked questions
What is the difference between an upsell and a cross-sell?
An upsell nudges the shopper toward a better or bigger version of what they are buying (the larger size, the premium model). A cross-sell offers a complementary product (the case for the phone, the beans for the coffee maker). Most of the apps above handle upsell & cross-sell together, so you rarely have to choose.
Do upsell apps slow down my Shopify store?
Some do, and it matters, because a slower store converts worse. The lighter apps run through Shopify's checkout extensibility instead of loading heavy scripts on every page. If speed is a concern, test your store's page speed before and after installing, and lean toward a Shopify upsell app built for performance.
How much can upselling actually add to revenue?
It varies by store and offer, but because upsells increase average order value on traffic you already paid for, even a modest lift compounds fast. We have seen it firsthand: €123K in upsell revenue for one B2B solar wholesaler and a 15% attach rate worth $22.5K for a heated-apparel brand, both from the same cart-and-checkout approach. The point is efficiency: you are earning more per visitor without buying a single extra click.
Can I run upsells without a paid app?
You can add basic "you may also like" blocks with some themes, but you will miss the one-click checkout and post-purchase offers where most of the money is. Several apps here, including ours, Selleasy and ReConvert, have genuine free tiers, so there is little reason to go without.
Which upsell app is best for a brand-new store?
Start with a free tier so you are not paying before you are earning. Webrex: Upsell & Cross Sell and Selleasy both let you launch free and only move to paid plans once the extra revenue justifies it.

The bottom line
The best Shopify upsell app is the one that matches where your shoppers are most ready to say yes. Cover the cart and checkout first, since that is where intent is highest, then layer in a post-purchase offer once the basics are earning. Pick one, measure its effect on average order value honestly, and let the results tell you whether to expand.
If you would rather have someone set the whole thing up so it matches your theme and actually moves AOV, that is what we do. Take a look at Webrex: Upsell & Cross Sell, or grab a free store audit, and we will tell you which upsell moves would earn you the most before you install anything.
