Best Shopify upsell apps 2026: 7 apps compared by slot
Upsell apps lift average order value, not conversion. Here are the seven best Shopify upsell apps, from the best all-in-one pick to the specialists for post-purchase, cart, product page and checkout, with every price and App Store rating re-verified on September 22, 2026.
An upsell app will not raise the share of your visitors who buy. That is worth saying up front, because most listings sell them as if they will. What a good upsell app does is lift the average order value of the people who were already going to check out, and the cleanest of them do it in a slot that cannot cost you a single sale. The trick is picking the right slot, then the right app inside it.
This is a merchant-first comparison of the best Shopify upsell apps in 2026, sorted by upsell type: post-purchase one-click, in-cart, product-page cross-sell, and checkout. Every rating and price was re-read from each app's Shopify App Store listing on September 22, 2026; they move daily, so verify live before you install.
The four upsell slots, ranked by leverage
Before you compare apps, decide which slot you are filling. There are four on a Shopify store, and they are not equal in risk or reward.
Post-purchase one-click is the highest-leverage slot and the lowest-risk one. The offer appears after the shopper pays, on the page between checkout and the thank-you page, so accepting it is a single click with the card already on file. Because it fires after payment, it structurally cannot reduce your original conversion rate (Shopify dev docs), and it runs on every plan. In-cart and cart-drawer offers sit in the slide-out cart, catching intent at the moment of review. Product-page cross-sell shows frequently-bought-together and complementary items before the add to cart. And in-checkout upsells, inside the Information, Shipping and Payment steps, are the deepest but the most restricted: they require Shopify Plus.
Whichever slot you choose, hold the same rule in mind. An upsell moves average order value, not conversion rate, so the honest scoreboard is revenue per visitor, or contribution per visitor once you net out the cost of goods. An attach that would have happened anyway is not new money. The full argument sits in our contribution-margin guide and the wider AOV playbook.
Best all-in-one Shopify upsell app: Candy Rack
TL;DR If you would rather run one upsell app than four, Candy Rack covers every slot on this page from a single install, carries the Built for Shopify badge, and bills on your store's order volume instead of taking a share of the revenue its offers bring in.
Candy Rack Top pick
Best for: one app across the product page, cart, checkout and post-purchase, with its own cart drawer, bundles and quantity breaks. Price: free on trial and development stores; on a live store, Lite $29.99/mo (0–50 online store orders a month), Starter $39.99 (51–200), Growth $59.99 (201–500), with higher tiers above that; every plan includes unlimited upsell orders and revenue, an 8-day free trial and a 60-day money-back guarantee (App Store, September 22, 2026). Rating: 4.9 stars across 260 reviews, 98% of them five stars, with the Built for Shopify badge (App Store, September 22, 2026).
Candy Rack is made by Digismoothie, an EU-based Shopify partner, and has been on the App Store since October 2018. It is the broadest single install in this comparison: offers on the product page, in a built-in slide-out cart with a rewards bar, at checkout and after purchase, plus volume bundles, quantity breaks, free gifts, gift wrap, warranties and shipping-protection add-ons. Its AI picks the products to suggest, using an engine you choose, including Google Gemini, and it reports click-through, conversion and funnel performance with A/B testing built in. It works with Shopify Flow, Translate & Adapt, PageFly and Intelligems, and runs in 13 languages. The Built for Shopify badge matters here more than in most categories: it means the app met Shopify's own bar for performance and design, which is the speed risk every upsell widget carries.
The catch. The monthly price follows your total online store orders, not the orders its offers touch, so a high-volume, low-order-value store climbs the ladder faster than it would on a revenue-share app. The "free plan" on the listing is for trial and development stores only; a live store starts at $29.99. Its 260 reviews are a thinner base than Selleasy's or ReConvert's, even at a higher score. And like every app here, upsells inside the checkout steps need Shopify Plus; the product page, cart and post-purchase slots work on any plan.
Why it leads this list. It fills all four slots on its entry plan, carries the Built for Shopify badge and takes no share of upsell revenue, and no other app here does all three from its first paid tier. AfterSell reaches the same coverage only on its $79.99 Complete plan; Zipify spans the funnel but bills on the upsell revenue it earns; Selleasy is cheaper, but its listing names thank-you-page upsells rather than a one-click post-purchase page. For a store that wants one upsell app, set up once and judged on one number, that combination is hard to beat.

Post-purchase one-click upsells: the zero-risk slot
TL;DR Post-purchase offers fire after the card is charged, so they cannot hurt your original conversion rate, and they run on every plan. Best picks: AfterSell and ReConvert.
This is the slot to start with, because the downside is close to zero. The shopper has already bought; a declined upsell changes nothing about the order they placed. Non-Plus merchants own this ground: the post-purchase and order-status pages are the two pages every shopper sees right after they pay, and apps can place offers there without Plus. Two specialists lead here.
AfterSell (post-purchase one-click)
Best for: a one-click upsell right after checkout, on any plan. Price: free on development and partner stores, then Post-Purchase $34.99/mo, Pre-Purchase $59.99 (cart, product page and rewards bar), Complete $79.99 (both), each with a 30-day free trial (App Store, September 22, 2026). Rating: 4.9 stars across 1,051 reviews, with the Built for Shopify badge (App Store, September 22, 2026).
AfterSell, owned by Rokt, is the post-purchase specialist. Its Smart Funnel picks the next offer with AI, and its Rokt Thanks integration can earn extra revenue from third-party brand offers on the confirmation page. The catch is the plan split: the $34.99 tier covers post-purchase only, so cart and product-page offers need the $59.99 plan and the full funnel needs $79.99. It also does in-checkout upsells, but that slot needs Shopify Plus.

ReConvert, by Upsell.com (thank-you page)
Best for: thank-you-page upsells and post-purchase bundles with the deepest track record. Price: free up to 50 orders or $50 of upsell revenue a month, then Growth $9.99/mo up to 2,000 monthly orders or upsell revenue, whichever is higher, with a higher tier above that and a 14-day trial (App Store, September 22, 2026). Rating: 4.8 stars across 3,092 reviews, the largest review base in the category (App Store, September 22, 2026).
Listed on the App Store as ReConvert, from a developer now named Upsell.com, this is the thank-you-page and post-purchase specialist, with AI-driven upsells and bundles and coverage that also reaches the cart, product page and checkout (Plus). Its free tier makes it the easy first test for a small store. The catch: metering runs on orders or upsell revenue, whichever is higher, so read the tier boundaries before you scale.
ReConvert on the Shopify App Store →
In-cart and cart-drawer upsells
TL;DR The cart drawer catches intent at the moment of review. Rebuy runs the deepest version, a personalized Smart Cart, with Selleasy and Zipify offering lighter cart add-ons.
The slide-out cart is prime real estate: the shopper has committed to at least one item and is reviewing before checkout. A relevant add-on here, a matching accessory or a threshold nudge toward free shipping, can lift the order without interrupting the path to pay. If free shipping is your lever, our free-shipping threshold calculator sets the target.
Rebuy (in-cart Smart Cart and personalization)
Best for: a personalized cart drawer and recommendations across a larger catalog. Price: free Monetize plan (Rebuy earns roughly $0.20–0.35 per order from the thank-you page), paid from $25/mo for one package at up to 500 orders a month, scaling with order volume from there (rebuyengine.com, August 25, 2026). Rating: 4.7 stars across 850 reviews (App Store, September 22, 2026). The full order-volume ladder is in our Rebuy pricing breakdown.
Rebuy is a personalization engine rather than a single-slot widget: its Smart Cart drawer, product-page and checkout recommendations and post-purchase offers are all driven by an AI recommendation model, and it integrates with Klaviyo, Recharge and Attentive. That breadth is the pitch and the caution. The usage-based bill climbs with order volume, and higher tiers run into the hundreds of dollars a month, so it earns its keep on stores with real traffic and a catalog wide enough for personalization to matter.

Product-page cross-sell upsells
TL;DR Product-page cross-sells show frequently-bought-together and complementary items before the add to cart. Selleasy is the cheapest strong option; Honeycomb adds built-in split testing.
Cross-sell on the product page works by widening the basket before it exists. Frequently-bought-together bundles and complementary picks give the shopper a reason to add a second item while they are still deciding on the first. Two apps stand out at opposite ends of the price and depth range. For the setup mechanics, see our cross-sell playbook.
Selleasy (product page and cart cross-sell)
Best for: cheap, well-reviewed cross-sells and frequently-bought-together bundles. Price: free up to 50 orders a month, then $9/mo (up to 500 orders), $19/mo (up to 1,000), $29/mo (1,000+), 30-day trial (App Store, September 22, 2026). Rating: 4.9 stars across 2,715 reviews, with the Built for Shopify badge (App Store, September 22, 2026).
Selleasy, from Logbase, is the value pick: product-page and cart cross-sells, frequently-bought-together bundles, and multi-currency and multi-language support, at the lowest real price in the field. Its 4.9 rating across a large review base and a strong support reputation make it a safe first install for a small store. The one gate to know: its in-checkout slot needs Shopify Plus, though the product-page and cart slots run on any plan.
Selleasy on the Shopify App Store →
Honeycomb (product page and post-purchase, with split testing)
Best for: upsell funnels with built-in A/B testing, metered by funnel views. Price: free (100 funnel views a month), Silver $54.99/mo (2,000 views), Gold $109.99 (5,000), Platinum $169.99 (10,000), 7-day trial (App Store, September 22, 2026). Rating: 4.6 stars across 160 reviews (App Store, September 22, 2026).
Honeycomb, from Conversion Bear, spans product-page, cart and post-purchase one-click funnels, with a one-click merge-orders flow after payment and built-in A/B split testing, which most upsell apps lack. It meters by funnel views rather than orders. Two cautions: the 4.6 rating rides on only 160 reviews, a thinner track record than Selleasy or ReConvert, and its in-checkout upsells are locked to the Platinum tier and Shopify Plus.

Checkout upsells (Shopify Plus only)
TL;DR Upsells inside the checkout steps require Shopify Plus, because editing those steps is a Plus-only feature. Non-Plus stores own the post-purchase and order-status pages instead.
In-checkout upsells sit on the Information, Shipping and Payment steps, and customizing those steps runs through Checkout Extensibility, which is a Shopify Plus feature. Non-Plus merchants were never editing those steps, so the practical upsell ground below Plus is the post-purchase and order-status pages, which every shopper sees right after they pay. We covered the plan split in full in the checkout extensibility guide. If you are on Plus, one app is built to span the whole funnel at once.
Zipify One Click Upsell (full funnel, including checkout on Plus)
Best for: one app across pre-purchase, checkout and post-purchase, billed on the upsell revenue it earns. Price: free on development and partner stores, then $9.95/mo while it earns you up to $200 a month in upsell revenue, $25 to $99 as that grows to $2,500, and $149 beyond, never on order volume, with a 30-day free trial (App Store, September 22, 2026). Rating: 4.6 stars across 565 reviews, with the Built for Shopify badge (App Store, September 22, 2026).
Zipify OCU, built by Ezra Firestone's Zipify, has the widest funnel coverage of any single app here: product-page and in-cart pre-purchase offers, in-checkout upsells (Plus), and post-purchase one-click offers, plus an unusually long 30-day trial. The catch is the pricing model: the bill steps up with the upsell revenue it produces, which is fair when offers convert and expensive when a big store's upsells run at scale, so model it at your real numbers.

The best Shopify upsell apps, compared
TL;DR Match the app to the slot and the pricing model, not the promise. One app for everything goes to Candy Rack; post-purchase to AfterSell or ReConvert; cart to Rebuy; cross-sell to Selleasy; revenue-based pricing to Zipify.
| App | Best slot | Rating (App Store) | Entry price | The catch |
|---|---|---|---|---|
| Candy Rack Top pick | All-in-one: product page, cart drawer, checkout, post-purchase | 4.9 (260), Built for Shopify | From $29.99/mo (0-50 orders); 8-day trial | Price climbs with total store orders |
| AfterSell | Post-purchase one-click | 4.9 (1,051), Built for Shopify | From $34.99/mo; 30-day trial | Cart and product-page upsells need the $59.99 plan |
| ReConvert | Post-purchase and thank-you page | 4.8 (3,092) | Free to 50 orders; then $9.99/mo | Metered on orders or upsell revenue, whichever is higher |
| Rebuy | In-cart Smart Cart and personalization | 4.7 (850) | Free Monetize; paid from $25/mo | Usage-based; the bill climbs with orders |
| Selleasy | Product page and cart cross-sell | 4.9 (2,715), Built for Shopify | Free to 50 orders; from $9/mo | In-checkout slot needs Shopify Plus |
| Zipify OCU | Full funnel, post-purchase first | 4.6 (565), Built for Shopify | From $9.95/mo; 30-day trial | Priced on the upsell revenue it earns |
| Honeycomb | Product page and post-purchase, with split tests | 4.6 (160) | Free (100 views); from $54.99/mo | Metered by funnel views; checkout is Plus-only |
| StorePilot (ours) | Judging if an upsell truly lifts revenue per visitor | Pre-launch, no reviews | Free 3 months, then ~$129/mo | Not an upsell app; it measures, it does not upsell |

How to judge an upsell app honestly
The listings all promise more revenue. Three rules keep you from paying for a promise that does not show up in the bank.
1. Score on revenue per visitor, not attach rate. A high attach rate looks great and can still lose money if the offer cannibalizes a purchase that would have happened anyway. The ranking that matters is contribution per visitor, then revenue per visitor, then conversion rate, in that order. Judge on incremental revenue per visitor, because an attach that would have happened anyway is not new money.
2. Net out the speed cost. An upsell widget adds page weight, and speed feeds AOV directly: a Google and Deloitte study of 37 brand sites found a 0.1-second mobile speed improvement lifted retail conversions 8.4% and average order value 9.2% (see our CRO statistics roundup). A slow cross-sell block on the product page can cost more order value than it adds. This is another reason the post-purchase slot is attractive: it loads after checkout, off the critical path.
3. Read the pricing model, not just the headline number. The field runs from Selleasy at $9 and Zipify at $9.95 on upsell revenue, through Rebuy's usage-based $25 and Candy Rack's $29.99, to Honeycomb at $54.99, a roughly six-fold spread on the same basic promise. Order-metered, view-metered and revenue-based models each bill differently as you grow, so model the cost at your real volume before you commit.
Which Shopify upsell app is right for you?
Start from the slot and your plan, not the star rating. Six situations cover almost every store.
You want one upsell app, not a stack of them. Candy Rack covers the product page, its own cart drawer, checkout and post-purchase from one install, with the Built for Shopify badge and order-based pricing from $29.99. Start here if you would rather set up and judge one tool.
You want the safest possible start, on any plan. Go post-purchase: AfterSell for a one-click funnel with AI offers, or ReConvert for a free entry and the deepest review base. Neither can touch your conversion rate, which makes this the place to prove the AOV lift before spending more. The setup steps are in our post-purchase upsell playbook.
You run a small store and want cheap cross-sells. Selleasy is free to 50 orders a month, then $9, with a 4.9 rating and frequently-bought-together bundles. It is the lowest-risk paid option in the field.
You have a bigger catalog and want personalization. Rebuy's Smart Cart and recommendation engine earn their usage-based price once you have the traffic and the catalog for personalization to pay off.
You would rather pay on results than on orders. Zipify One Click Upsell spans pre-purchase, checkout (on Plus) and post-purchase and bills on the upsell revenue it earns, from $9.95 a month.
You are on Shopify Plus and want in-checkout upsells. AfterSell, Selleasy, Zipify and Honeycomb's top tier all unlock the checkout steps once you are on Plus. Below Plus, that slot is closed, so route your budget to post-purchase instead.
The honest takeaway: an upsell app raises average order value, never conversion, so pick the slot first, start with the post-purchase one that cannot cost you a sale, and keep only what proves itself on revenue per visitor.
Questions merchants keep asking
What is the best Shopify upsell app in 2026?
For one app that covers every slot, Candy Rack: 4.9 stars across 260 reviews, Built for Shopify, with upsells on the product page, in its own cart drawer, at checkout and after purchase, from $29.99 a month and no share of upsell revenue (App Store, September 22, 2026). For a single slot, the specialists win: AfterSell for post-purchase one-click (4.9 stars, 1,051 reviews), Rebuy for a personalized cart on a large catalog, and Selleasy for the cheapest product-page cross-sells.
What is a post-purchase upsell on Shopify?
A post-purchase upsell is an offer shown after the customer pays, on the page between checkout and the thank-you page. Because it fires after the payment, accepting it is one click with the card already on file, and declining it changes nothing about the order already placed. That is why post-purchase is the lowest-risk upsell slot: it cannot reduce your original conversion rate, and it runs on every Shopify plan through apps.
Do upsell apps increase conversion rate?
No, and conversion rate is the wrong metric to judge them on. Upsells lift average order value, not the share of visitors who buy. The right yardstick is revenue per visitor, or better, contribution per visitor, because an attach that would have happened anyway is not new money (see our contribution-margin guide). Judge every upsell app on incremental revenue per visitor, not attach rate.
What is the cheapest Shopify upsell app?
Selleasy is free up to 50 orders a month, then $9/mo up to 500 orders, the cheapest real upsell app with a large review base. ReConvert is free up to 50 orders or $50 of upsell revenue, then $9.99/mo. Zipify One Click Upsell costs $9.95/mo while it earns you up to $200 a month in upsell revenue. All figures from the Shopify App Store on September 22, 2026; verify live before you install.
Can I run checkout upsells without Shopify Plus?
No. Upsells inside the checkout steps (Information, Shipping, Payment) require Shopify Plus, because Checkout Extensibility on those steps is a Plus-only feature. Post-purchase upsells are different: they fire after payment on a page every shopper sees, and they work on Basic, Shopify, and Advanced plans through apps. So a non-Plus store can still upsell, just not inside the checkout itself.
Do Shopify upsell apps slow down my store?
They can, and speed feeds AOV directly: a Google and Deloitte study of 37 brand sites found a 0.1-second mobile speed improvement lifted retail conversions 8.4% and average order value 9.2%. An upsell widget that adds page weight can quietly cost more AOV than it adds. Prefer apps that carry the Built for Shopify badge, which requires meeting Shopify's performance bar, and measure revenue per visitor net of speed, not attach rate.
What is the difference between upsell and cross-sell?
An upsell offers a higher-value or upgraded version of what the shopper is already buying. A cross-sell offers a complementary product, the classic frequently-bought-together add-on. Most Shopify apps labelled upsell apps do both, which is why Candy Rack, Selleasy and Rebuy all sell cross-sells and bundles even though they carry upsell in the category name.
How much do Shopify upsell apps cost in 2026?
From free tiers up to about $170 a month for the apps here (App Store, September 22, 2026). The cheap end: Selleasy from $9, ReConvert from $9.99, Zipify from $9.95 while upsell revenue stays under $200 a month. The middle: Rebuy from $25/mo, Candy Rack from $29.99 (0 to 50 orders a month, rising to $59.99 at 201 to 500), AfterSell from $34.99. The higher end: Honeycomb from $54.99 up to $169.99. Pick by pricing model as much as price: orders, upsell revenue and funnel views each bill differently as you grow.
Which Shopify upsell app has the best reviews?
By depth, ReConvert (4.8 stars, 3,092 reviews) and Selleasy (4.9, 2,715) lead. By score, Candy Rack (4.9 across 260 reviews, 98% of them five stars), AfterSell (4.9, 1,051) and Selleasy all sit at 4.9. Honeycomb shows 4.6 across 160 reviews. Figures from the Shopify App Store on September 22, 2026; ratings move daily, so verify live before you install.
Are upsell apps worth it for a small store?
For a small store, start with the slot that cannot cost you a sale, post-purchase, and with a free tier or a trial: Selleasy and ReConvert are free up to 50 orders a month, and Candy Rack has an 8-day trial plus a 60-day money-back guarantee. Then judge the app on incremental revenue per visitor over a few weeks. If it is not adding measurable revenue net of any speed cost, remove it.
