18 Best Shopify Upsell Apps: Free & Paid (Verified Sep 2026)

Short answer: For the cart drawer, Oxify Cart Drawer & Upsell (4.9, 37 reviews, from $9.99/mo, Built for Shopify) is the pick, because it replaces the slide cart and runs product page, post-purchase and thank-you offers from the same install. For the product page and Frequently Bought Together, Essential Upsell & Cross Sell (5.0, 2,259 reviews, free until $100 of upsell revenue) wins. For post-purchase and Shopify Plus checkout offers, AfterSell (4.8, 915 reviews, from $34.99/mo) is the specialist. The best free start is Selleasy (4.9, 2,541 reviews, free under 50 orders a month), and large catalogs with a CRO team should look at Rebuy.

Quick answer: the best app for each placement

How we ranked these apps

We do not publish a single “#1 best” ranking, because the four upsell placements solve different problems and are won by different apps. Ranking a cart drawer app against a post-purchase app produces a number that is not useful to anyone.

For every app we opened the live Shopify App Store listing on 2 September 2026 and recorded the rating, review count, plan ladder and free-plan limits, whether the Built for Shopify badge appears on the app’s own header (not on the “more apps like this” cards lower down), and which placements the listing itself claims. Where higher tiers sit behind “see all pricing options”, we say so rather than guess.

Disclosure: Oxify builds two of the apps on this list — the cart drawer app and the quantity breaks app. Both have small review counts next to the established players, and we say so in their entries. They are placed as category picks on placement coverage and pricing structure, which are verifiable, not on popularity, which they have not yet earned.

The 4 upsell placements (and what each is for)

Most lists cover three. There are four, and each reaches a different shopper at a different moment.

1. Product page upsell (before add to cart)

Shown before the shopper commits. Best for Frequently Bought Together bundles, multi-packs, premium tiers, and add-ons like gift wrap or warranty. It reaches the most people and is the easiest to overdo. Full setup guide: Product page upsell on Shopify.

2. Cart drawer upsell (inside the slide cart)

Reaches every shopper who adds to cart. Free-shipping progress bars and free-gift thresholds are the natural offers here, because extra costs are the top stated reason for abandonment. See the cart upsell strategy guide and how to add upsells to your cart drawer.

3. Post-purchase upsell (one click after checkout)

Shown after payment is captured, before the thank-you page. The customer accepts with one tap and no re-entry of card details, so it cannot hurt checkout conversion. It works on every Shopify plan, but Shopify does not display it for wallet, installment or gift-card payments, so a store with heavy Shop Pay or Apple Pay usage will see fewer impressions than its order count suggests. See one-click post-purchase upsell setup and the post-purchase app roundup.

4. Thank-you page upsell

The order status page, shown after the post-purchase offer. Best for reorder prompts, subscription upgrades, referrals and review requests. Apps can customise it on Basic and higher. See how to add a thank-you page upsell.

These placements stack rather than compete, which is why placement coverage is the first thing to read in the table below.

Quick comparison: 18 best Shopify upsell apps

Placement columns reflect what each listing claims. “Dev stores only” means the free plan is restricted to development stores, so a live store pays after the trial.

Which apps cover all four placements in one install?

Eight of the 18 apps claim all four placements from a single install — double what earlier versions of this article said. Full coverage is no longer rare, so the tie-breakers are price at your order volume, the Built for Shopify badge, and how good the cart drawer itself is.

The short version: Selleasy is the cheapest way to get offers in all four spots. Oxify Cart Drawer and Candy Rack also replace the cart drawer, which matters if the reward bar, add-ons and free gift are the offers you will lead with. Rebuy is the only one with enterprise recommendation logic; Zipify and Honeycomb are the funnel-testing picks.

Best cart drawer upsell apps

Oxify Cart Drawer & Upsell

Rating: 4.9 (37 reviews) · Built for Shopify: yes · Where it shows: product page, cart drawer, post-purchase, thank-you page

What it does differently: A slide-cart replacement first — multi-tier rewards bar, free gift with auto-applied discount, add-ons such as shipping protection and gift wrap, in-cart subscription upgrade, BOGO and quantity breaks — that also runs product page, one-click post-purchase and thank-you offers from the same install.

Pricing: By monthly store orders, every feature on every plan, 14-day free trial, no revenue share: $9.99 (0–100 orders), $19.99 (101–200), $29.99 (201–500), $49.99 (501–1,000), then $79.99, $99.99 and $149.99 at 3,000+ orders, plus an optional $299/mo Enterprise plan with 24/7 support and 1:1 onboarding. A high-AOV store pays the same as a low-AOV store at the same order count.

Cons: 37 reviews is a small sample · no free tier, only a trial · shorter track record

Who should avoid it: Stores under about 50 orders a month, where Selleasy or Essential Upsell will prove the concept free. Skip it too if you need enterprise AI recommendation logic across a 10,000-SKU catalog — that is Rebuy’s job.

UpCart

Rating: 4.7 (875 reviews, App Store) · Built for Shopify: yes · Where it shows: cart drawer only

What it does differently: A cart drawer specialist. Its strength is design control and the rewards bar (“spend $10 more for free shipping”), plus announcement, upsell and add-on modules and custom HTML/CSS.

Pricing: $29.99/mo (0–200 orders), $34.99 (201–500), $54.99 (501–1,000), 14-day trial. The listing’s free plan is for development stores only.

Cons: Cart drawer only — no product page, post-purchase or thank-you offers · three times iCart’s entry price at the same order band

Who should avoid it: Anyone who wants post-purchase upsells; budget for a second app.

iCart Cart Drawer Cart Upsell

Rating: 4.7 (435 reviews, App Store) · Built for Shopify: no · Where it shows: cart drawer, cart popup, cart page

What it does differently: The cheapest way into cart drawer upselling: the first 100 orders are free for life, then $9/mo (0–100 orders), $19 (101–200) and $29 (201–500) with every feature included — sticky cart, multi-tier progress bar, AI cart upsells, bundles and volume discounts.

Cons: No Built for Shopify badge on the listing · cart placement only · design polish trails UpCart

Who should avoid it: Brands where the cart drawer is part of the brand experience, and anyone who wants post-purchase coverage. See our iCart alternative comparison.

Best product page and Frequently Bought Together apps

Essential Upsell & Cross Sell

Rating: 5.0 (2,259 reviews, App Store) · Built for Shopify: yes · Where it shows: product page, cart, post-purchase

What it does differently: Frequently Bought Together, related products and add-ons on the product page plus one-click post-purchase offers, priced by the extra revenue it generates rather than your order count — so it pays for itself before it charges you.

Pricing: Free until $100 of additional revenue (product page and post-purchase offers only), Starter $9.99/mo to $500, Essential $19.99/mo to $1,000 (adds cart page offers), Professional $39.99/mo unlimited. 14-day trial on paid plans.

Cons: No thank-you page offers on the listing · cart offers only from the $19.99 plan · no cart drawer design control

Upsell & Cross Sell — Selleasy (by Logbase)

Rating: 4.9 (2,541 reviews, App Store) · Built for Shopify: yes · Where it shows: product page, cart, checkout (Plus), post-purchase, thank-you page

What it does differently: The app most often recommended to merchants who have never run an upsell, and on today’s pricing also the cheapest app that covers all four placements. Paid tiers are counted on total store orders, not upsell revenue.

Pricing: Free to install up to 50 orders/mo, then $9/mo to 500 orders, $19/mo to 1,000, $29/mo above 1,000. 30-day trial on paid tiers, and a free setup call is included.

Cons: Widgets live inside your theme’s cart rather than replacing it · fewer design controls · analytics are basic

Who should avoid it: Brands that want a designed slide cart with rewards bar and add-ons; pair it with a cart drawer app or pick one that does both. See our Selleasy alternative guide.

Frequently Bought Together CBB

Rating: 4.8 (1,049 reviews, App Store) · Built for Shopify: yes · Where it shows: product page

What it does differently: Replicates the Amazon-style FBT module from purchase-history data, with manual and automatic bundles and bundle discounts. If your only gap is the product page, this is the cleanest fix. Compare approaches in manual vs AI FBT and the FBT app roundup.

Pricing: Free Starter plan (max 3 manual bundles, basic widget), then $14.99/mo to 50 orders, $19.99/mo to 500 orders, $39.99/mo above 500. 14-day trial.

Cons: Product page only · the free plan is a 3-bundle demo

Who should avoid it: Anyone who needs more than one placement.

Best post-purchase and thank-you page upsell apps

AfterSell (by Rokt)

Rating: 4.8 (915 reviews, App Store) · Built for Shopify: yes · Where it shows: post-purchase, checkout (Plus), thank-you page

What it does differently: The most established name for one-click upsell and downsell funnels after payment, with checkout blocks for Plus stores, AI offer recommendations and built-in A/B testing. It does not touch the product page or the cart.

Pricing: $34.99/mo (0–500 orders), $54.99 (501–1,000), $99.99 (1,001–2,000), higher tiers on request. 30-day trial; free plan is for development stores only.

Cons: No product page or cart offers · checkout blocks need Plus · highest entry price of the post-purchase specialists

Who should avoid it: Stores that need product page or cart coverage, and stores under about 200 orders a month where $34.99 is hard to earn back. See the AfterSell alternative guide.

Upsell.com (formerly ReConvert)

Rating: 4.8 (2,810 reviews, App Store) · Built for Shopify: no · Where it shows: product page, cart, checkout (Plus), post-purchase, thank-you page

What it does differently: Still the most flexible thank-you page builder on Shopify — drag-and-drop upsells, surveys, reorder prompts and referrals — now grown into a full funnel with product page, cart and one-click post-purchase offers plus A/B testing.

Pricing: $4.99/mo up to 50 orders or $50 of upsell revenue, $9.99/mo to 100 orders or $100, $19.99/mo to 200 orders or $200. Each tier is capped by both numbers, and the listing says charges rise with either. 14-day trial; free plan is for development stores only.

Cons: No Built for Shopify badge today · published tiers stop at 200 orders, so check the full pricing table first · learning curve

Who should avoid it: Stores that want a predictable flat fee at 500+ orders. See the ReConvert alternative guide.

Zipify OneClickUpsell (OCU)

Rating: 4.5 (503 reviews, App Store) · Built for Shopify: yes · Where it shows: product page, slide cart, checkout (Plus), post-purchase, thank-you page

What it does differently: The original one-click post-purchase app, now a full funnel with split-testing across every placement. The listing now shows a single Unlimited plan at $8/mo that “scales with generated upsell revenue”; the older $35 + 1% structure is gone.

Pricing: From $8/mo, scaling with upsell revenue on an unpublished ladder; 30-day trial; a flat-fee Zipify Plus tier is quoted on request.

Cons: 4.5 rating, second-lowest on this list · cost depends on an unpublished revenue scale · overkill for small stores

Who should avoid it: Stores that want a fixed monthly bill.

SMART Checkout Rules & Upsells

Rating: 5.0 (668 reviews, App Store) · Built for Shopify: yes · Where it shows: checkout (Plus), post-purchase, thank-you page

What it does differently: Checkout validation and payment/shipping rules plus checkout blocks and one-click post-purchase upsells and downsells, and the listing price is simply “Free”.

Cons: Checkout blocks need Shopify Plus · no product page or cart offers

Who should avoid it: Non-Plus stores that only want upsells; the post-purchase part works, but the rules half does not.

Best bundle and quantity break apps

Kaching Bundles App & Upsells

Rating: 5.0 (5,437 reviews, App Store) · Built for Shopify: yes · Where it shows: product page

What it does differently: The most-reviewed bundle app on Shopify: a quantity-break and bundle widget that is fast to set up and includes A/B testing. Earlier versions of this article cited a 1% revenue share; today’s listing shows none — tiers are capped by the extra revenue the app generates instead.

Pricing: Starter $14.99/mo (up to $1,000 of additional revenue), Scale $29.99 (to $5,000), Pro $59.99 (to $10,000), annual discounts of about 25%, 7-day trial. The free plan is for development stores only.

Cons: Product page only · the $59.99 tier ends at $10k of bundle revenue and the next step is not published

Who should avoid it: Stores that want the quantity break to live in the cart drawer as well. See our Kaching alternative comparison.

Oxify Quantity Breaks & BYOB

Rating: 4.8 (13 reviews, App Store) · Built for Shopify: yes · Where it shows: product page

What it does differently: Tiered quantity pricing, build-your-own-box, mix-and-match and fixed bundles in one app, listed at “Free” with no revenue cap. It is a separate app from the cart drawer above. Background reading: how many discount tiers to use and the bundle app roundup.

Cons: 13 reviews is the smallest sample on this list · product page only

Amplify (formerly PickyStory)

Rating: 4.5 (520 reviews, App Store) · Built for Shopify: no · Where it shows: product page, cart, thank-you page

What it does differently: The deepest bundle logic available — bundle as product, bundle builder, mix-and-match, shop the look, quantity breaks and AI offers. It handles bundle scenarios other apps cannot express.

Pricing: One “Pay as You Grow” plan from $99.50/mo for stores up to $30k in monthly revenue, volume-priced above that; 30-day trial, no free plan.

Cons: $99.50 entry · no post-purchase offers on the listing · no Built for Shopify badge

BOGOS: Free Gift Bundle Upsell

Rating: 5.0 (4,122 reviews, App Store) · Built for Shopify: yes · Where it shows: product page, cart, thank-you page

What it does differently: Specialises in Buy X Get Y, gift-with-purchase and threshold gifts with progress bars, plus bundles and volume discounts. See how to add a free gift with purchase.

Pricing: Free for the first 30 orders (lifetime), then plans tied to your Shopify plan: Basic $29.99/mo (300 BOGOS orders, Shopify Basic stores only), Grow $49.99 (600 orders), Plus $109.99 (2,000 orders, adds checkout upsell), each at $0.05 per extra order. 7-day trial.

Cons: No post-purchase offers · plan eligibility is tied to your Shopify plan, so a Grow store cannot buy the $29.99 tier

Best all-in-one and enterprise apps

Rebuy Personalization Engine

Rating: 4.7 (748 reviews, App Store) · Built for Shopify: no · Where it shows: product page, Smart Cart, checkout (Plus), post-purchase, thank-you page, search and collections

What it does differently: The deepest AI personalisation on Shopify across every surface, with A/B testing and a free “Monetize” option that pays you per order for third-party thank-you page offers. Powerful, and demanding.

Pricing: Build-your-own packages from $25/mo, priced by monthly orders, 14-day trial; the full Platform One plan is $534/mo on Rebuy’s own pricing page.

Cons: No Built for Shopify badge on the listing · needs someone to own it · cost climbs steeply with order volume

Who should avoid it: Any store without a person whose job includes conversion optimisation. See our Rebuy alternative comparison.

Candy Rack (Digismoothie)

Rating: 4.9 (223 reviews, App Store) · Built for Shopify: yes · Where it shows: product page, built-in cart drawer, checkout (Plus), post-purchase, thank-you page

What it does differently: The cleanest visual execution of upsell offers, with a built-in slide cart, Gemini-powered AI suggestions, quantity breaks, and an EU-hosted, GDPR-first stance.

Pricing: Lite $29.99/mo (0–50 orders), Starter $39.99 (51–200), Growth $59.99 (201–500), higher tiers on request; 8-day trial and a 60-day money-back guarantee. No revenue share.

Cons: $29.99 buys only the 0–50 order band · smaller review base · fewer targeting rules than the funnel apps

Honeycomb Upsell & Cross Sell (Conversion Bear)

Rating: 4.6 (145 reviews, App Store) · Built for Shopify: no · Where it shows: product page, cart page, checkout (Plus), post-purchase, thank-you page

What it does differently: Multi-step upsell and downsell funnels with split testing, and a free tier that includes every placement. Pricing is by funnel views rather than orders, so model it before you install.

Pricing: Free (100 funnel views/mo), Silver $54.99/mo (2,000 views, removes branding), Gold $109.99 (5,000), Platinum $169.99 (10,000); 7-day trial.

Cons: First paid tier is $54.99 · view-based pricing punishes high-traffic, low-conversion stores · no Built for Shopify badge

Bold AI Upsell & Cross-Sell

Rating: 4.4 (529 reviews, App Store) · Built for Shopify: yes · Where it shows: product page, cart, checkout (Plus, Advanced plan), post-purchase, thank-you page

What it does differently: AI-driven true upsells (swap for the better version) and cross-sells that integrate with Bold’s subscription and pricing tools. The integration is the reason to pick it.

Pricing: Standard is free to install plus 3.5% of upsell revenue; Advanced is $10/mo plus 2.5%, adding free-gift offers and in-checkout offers for Plus. This is the only revenue-share pricing left on the list.

Cons: Lowest rating on this list · a revenue share grows with your success · weaker standalone value

Who should avoid it: Stores not already using Bold.

Best free Shopify upsell apps (real limits)

“Free plan available” often means development stores only. These are the plans a live store can run at $0, and the limit that ends them:

• Selleasy — free to install up to 50 store orders a month, all four placements included. The best free upsell app for a new store.
• Essential Upsell & Cross Sell — free until the app has generated $100 of additional revenue; product page and post-purchase offers only.
• SMART Checkout Rules & Upsells — fully free; the post-purchase offers work on any plan, the checkout blocks need Plus.
• Oxify Quantity Breaks & BYOB — fully free for quantity breaks and build-your-own-box bundles.
• Honeycomb — free for 100 funnel views a month across every placement, with Honeycomb branding on the offer.
• iCart — the first 100 orders are free for life, then $9/mo.
• BOGOS — the first 30 orders are free for life, then $29.99/mo.
• Frequently Bought Together CBB — free Starter plan limited to 3 manual bundles.
• Bold AI Upsell — no monthly fee, but 3.5% of upsell revenue.

Not free for a live store, despite the label: UpCart, AfterSell, Upsell.com, Kaching, Zipify, Rebuy and Candy Rack restrict their free plan to development or partner stores.

Best upsell app for DTC brands on Shopify

Direct answer: for a DTC brand doing roughly 200–2,000 orders a month, pick a flat-fee app that owns the cart drawer and also runs post-purchase: Oxify Cart Drawer & Upsell ($19.99–$79.99/mo across that range) is the value pick and Candy Rack ($39.99–$59.99/mo to 500 orders, higher on request) is the design-led pick. Add AfterSell when post-purchase becomes your main lever and you want dedicated funnel testing, and move to Rebuy once you have a CRO owner and several thousand orders a month.

Why the cart drawer leads for DTC: checkouts are wallet-heavy (Shop Pay, Apple Pay) and Shopify does not show post-purchase offers on wallet payments, so the drawer sees far more shoppers; DTC AOV rests on multi-packs, subscriptions and gift-with-purchase, which are drawer mechanics; and theme speed is a brand asset, so the Built for Shopify badge is worth filtering on.

Best Shopify Plus and checkout upsell apps

Offers on the information, shipping and payment steps run through checkout UI extensions, which are Plus only. AfterSell and SMART Checkout Rules are the specialists; Selleasy, Upsell.com, Zipify, Candy Rack, Honeycomb, Bold (Advanced plan) and Rebuy also list checkout offers for Plus stores. Not on Plus? Post-purchase and thank-you page offers work on every plan — see checkout upsell on Shopify.

What each app costs at your order volume

Read the published tier for the order band you are actually in; where a listing stops publishing tiers we say “on request”. Figures from today’s listings.

Revenue-capped apps behave differently: Essential moves from free to $39.99 as upsell revenue passes $100, $500 and $1,000; Kaching steps $14.99 to $59.99 as bundle revenue passes $1k, $5k and $10k; Bold takes 2.5–3.5% of upsell revenue. If upsells add $3,000 a month, Bold’s Standard plan costs $105 — more than Oxify, UpCart, AfterSell or Selleasy charge at 500 orders. Model your own numbers with the AOV calculator and how to measure cart upsell performance.

How to choose, then set up, in one afternoon

1. Count your placements first. One app covering the spots you need beats three specialists; stacking means duplicate cart scripts and bills. Keep a specialist only where it is best-in-class for your single gap.
2. Pick the pricing model for your volume using the table above, not the “from” price.
3. Start with one placement and one hero offer — your best complementary product, priced well below the main item — and add a cheaper downsell for declines. See how to write offers that convert.
4. Install on a duplicate theme, check mobile, measure for 14 days, then add the next placement; launching all four at once hides which one worked. Worried about conversion? Read do upsells hurt conversion rate.

Frequently Asked Questions

Sources and changelog

Ratings, review counts, plan ladders and Built for Shopify badges were read from each live Shopify App Store listing on 2 September 2026 (links on every entry). Plan rules come from shopify.dev and help.shopify.com; abandonment data from Baymard.

2 September 2026: removed In Cart Upsell (listing “not currently available”); corrected Kaching (no revenue share), Zipify, Rebuy, Honeycomb and Frequently Bought Together pricing or ratings and the Built for Shopify status of five apps; deleted conversion percentages we could not source; added the DTC, free-plan and cost-at-volume sections.

Pick the placement before you pick the app. If you can only run one, run the cart drawer for reach or post-purchase for intent; if you want the full lift, cover all four with a flat-fee app so the cost does not scale with your success. For broader tactics, see Shopify upselling strategies.
