Best Shopify Checkout & Post-Purchase Upsell Apps (16 Compared, 2026)

Do you need Shopify Plus for a checkout upsell app? Only for offers on the payment page. On every other plan you can show the offer in the cart or right after payment, and most stores should start there.

A checkout upsell is a small offer a shopper sees while buying, like "Add a travel pouch for $6." One tap and it joins the order. It can show in the cart, on the payment page, or right after payment.

This list covers 16 checkout and post-purchase upsell apps. It sorts them by where the offer shows, which Shopify plan you need, and what you really pay. It also shows which apps say they handle subscriptions and A/B tests.

Ratings, review counts and prices: live App Store listings, November 8, 2026 (SMART's price: November 1). Shopify rules: Shopify.dev, November 8. Oxify is our app. It is listed first in its group, and we say where it is weaker.

Do You Need Shopify Plus? What Each Plan Can Show

Apps use "checkout upsell" for three different places. Pick the wrong one and the app shows nothing.

• "Not on Plus" means Basic, Grow or Advanced. Starter is out for after-payment offers.
• The payment page is the only Plus-only place. Shopify: those extensions are "available only to stores on a Shopify Plus plan."

Sources: Shopify's product offers guide and checkout technologies page, read November 8, 2026. The Shopify checkout upsell guide covers the Plus question in full.

The same facts as a table. "Not listed" means the listing does not name that place.

All 16 show offers after payment. Twelve list payment-page offers (Plus). Eight also show offers in the cart. Want only the cart or thank-you page? See our cart drawer apps and thank-you page apps.

How We Picked These 16 Apps

• Where we looked: the App Store search for "checkout upsell" on November 1, 2026 (below), Shopify's checkout-upsell collection, and apps in top search results. The listing had to say the app shows offers at checkout or right after it.
• At least 50 reviews: ours has 44. We list it anyway because this is our site, and we mark it as ours.
• Why these 16: the most reviews or a clear niche (free, flat price, Plus-only). The rest are in Also Checked.
• What we copied: rating, review count, Built for Shopify badge (Shopify's quality badge) and plans, from each live listing on November 8. Subscription and A/B claims also come from the app makers' sites.
• What we did not do: install the other 15 apps. This tells you what each app says it does and costs, not how well it works.
• Rebuy: see our Rebuy alternatives guide.

All-in-One Apps: Cart, After Payment and the Payment Page

These apps cover more than one place. The payment-page part needs Plus.

1. Oxify Cart Drawer & Upsells (our app)

Best for: stores under about 300 orders a month that want cart, after-payment and (on Plus) payment-page offers in one app.

• Rating: 4.9 from 44 reviews. Built for Shopify.
• Price: from $9.99 a month for up to 100 orders. $49.99 at 501 to 1,000 orders. $79.99 at 1,001 to 2,000 (the App Store shows the first four tiers; the rest are on our pricing page). 14-day free trial.
• Also in the app: product page and thank-you page offers, reward bar, free-shipping bar, free gifts, quantity breaks, gift wrap and subscription-app upgrades in the cart.
• Where it is weaker: 44 reviews (far fewer than ReConvert or Selleasy), no free plan, and a price that rises with orders. The listing names A/B testing under analytics, with less detail than ReConvert or Zipify OCU.

2. Selleasy

Best for: the best free plan that covers several places.

• Rating: 4.9 from 2,778 reviews. No Built for Shopify badge.
• Price: free plan with unlimited orders, up to 5 campaigns and 18 upsell strategies. Starter $9 a month. Pro $29. Max $59. 30-day trial on paid plans.
• Good: no order limit on the free plan, and the Plus checkout upsell comes with the $29 Pro plan. It also shows offers on thank-you and order status pages.
• Watch out: no Built for Shopify badge, and the free plan stops at 5 campaigns. See our Selleasy alternatives.

3. ReConvert (Upsell.com)

Best for: the biggest review base and a drag-and-drop editor.

• Rating: 4.8 from 3,135 reviews. No Built for Shopify badge.
• Price: free up to 50 orders or $50 of upsell sales. $9.99 a month for 51 to 100 orders. $19.99 for 101 to 200. $39.99 for 201 to 500. 14-day trial on paid plans.
• Good: the free plan lists A/B testing and funnels. The listing says it is easy to switch from Rebuy, AfterSell, Selleasy or UpCart.
• Watch out: prices above 500 orders are not on the listing, and 50 free orders is small. See our ReConvert alternatives.

4. UpsellPlus Checkout Upsell

Best for: stores that want A/B tests and subscription upgrades in every place, with a plan built for Plus checkout.

• Rating: 5.0 from 151 reviews. Built for Shopify.
• Price: building offers is free. To publish them you start a 14-day trial, then pay. Launch $49 a month (up to $500 of upsell sales). Plus $119 (up to $2,000). Scale $199 (up to $5,000).
• Good: it reaches customer accounts and Shopify POS. Its site names subscription upgrades for Appstle, Recharge and Seal subscribers, and A/B tests with holdouts.
• Watch out: the price rises as upsell sales rise. Checkout upsells show up in the $119 Plus plan.

5. Zipify OneClickUpsell (OCU)

Best for: stores that want to pay by upsell sales, not by order count.

• Rating: 4.6 from 578 reviews. Built for Shopify.
• Price: $9.95 a month up to $200 of upsell sales. $25 to $99 from $200 to $2,500. $149 above $2,500, never more than $999. 30-day trial. Every tier gets every placement.
• Good: AI upsells and A/B/C/D split tests on every tier. Its FAQ says it can upsell subscriptions in the cart, before checkout and after payment.
• Watch out: a lower rating than most (4.6). Your bill grows when upsells work. That is fair, but plan for it.

6. AfterSell (Rokt)

Best for: after-payment funnels with downsells, plus Plus checkout offers.

• Rating: 4.9 from 1,121 reviews. No Built for Shopify badge.
• Price: Post-Purchase $34.99 a month plus $0.05 per order above 500 (capped at $999.99). Pre-Purchase $59.99 plus $0.03 above 500 (cap $599.99). Complete $79.99 plus $0.07 above 500 (cap $1,359.99). 30-day trial. Source: AfterSell's billing doc.
• Good: the $34.99 plan lists smart funnels, thank-you offers, Plus checkout upsells and subscription upgrades. The $59.99 plan lists free gifts, reward bars and A/B testing.
• Watch out: it costs more than most to start, and the cart sits in a separate plan. See our AfterSell alternatives.
• Also on the listing: Rokt Thanks shows other brands' offers (it names Disney+ and Nike) and pays you up to $0.80 an order, for stores over 1,000 orders a month. That is not selling your own products.

7. Candy Rack

Best for: stores that want a slide cart with offers, plus after-payment and checkout offers.

• Rating: 4.9 from 269 reviews. Built for Shopify. Made by Digismoothie.
• Price: $29.99 a month for 0 to 50 orders. $39.99 for 51 to 200. $59.99 for 201 to 500. 60-day money-back promise.
• Good: unlimited upsell orders and revenue on every plan. Its site says you can A/B test through Intelligems, for offers shown before checkout.
• Watch out: a short 8-day trial, and no free plan for live stores.

Payment-Page Apps (Shopify Plus)

These apps focus on the checkout itself. Shopify only allows payment-page offers on Plus, so plan for Plus.

8. Checkout Plus

Best for: Plus stores that want a block builder for the payment page.

• Rating: 5.0 from 130 reviews. Built for Shopify. Made by Plus Apps.
• Price: Basic $19 a month (thank-you page, order status page and post-purchase offers). Plus $49 (checkout changes, Plus only). Advanced $99 (checkout upsells and auto-added gifts, Plus only). 7-day trial.
• Watch out: the checkout upsell is in the $99 plan only. The "free" plan is for development and staging stores.

9. Wiz: Checkout Upsell

Best for: stores that want different plans for non-Plus and Plus checkouts.

• Rating: 4.9 from 59 reviews. Built for Shopify. Made by Skai Lama.
• Price: Essential $49 a month (after-payment, thank-you and order status offers; the listing says it is not for Plus stores). Plus Growth $99 (checkout upsells, subscription upgrades, banners, reviews, trust badges, free gifts). Checkout concierge $199. 14-day trial.
• Good: a clear split by Shopify plan. Its site also lists A/B testing.
• Watch out: a Plus store cannot use the $49 plan. Only 59 reviews so far.

10. Checkout Components

Best for: stores that want to show different checkout offers to different customer groups.

• Rating: 5.0 from 69 reviews. Built for Shopify.
• Price: Starter $49.99 a month (one manual checkout upsell, plus post-purchase offers). Growth $99.99 (unlimited checkout upsells). Pro $199.99 (A/B tests and reports by customer segment). Enterprise $299.99 (for businesses upselling $100k+). 14-day trial. Flat prices, no commission.
• Good: it targets offers by Shopify customer segment and can add gift-message and delivery-note fields.
• Watch out: Starter has one manual checkout upsell, and A/B tests start at $199.99.

11. Qikify Checkout Customizer

Best for: stores that want free checkout rules first, and upsells later on Plus.

• Rating: 4.9 from 73 reviews. Built for Shopify. Made by Qikify Plus.
• Price: free on every plan for payment-method rules, custom delivery methods and checkout checks. Checkout Premium $99 a month adds product offers, custom fields, badges and post-purchase extensions. 14-day trial.
• Watch out: the free plan is useful on any Shopify plan, but it is for rules, not upsells. Upsells start at $99.

12. CartHook Upsell

Best for: stores that prefer to pay per order.

• Rating: 4.1 from 93 reviews. No Built for Shopify badge.
• Price: free to install. 20 orders a month are free, then $0.12 an order plus 1% of upsell sales. Growth $49 a month (1,000 orders included, then $0.14 an order, no share of upsell sales). Scale $149. 14-day trial.
• Good: up to 12 products in one offer, accept and decline funnels, and subscriptions with Recharge or Seal. Its site lists A/B testing.
• Watch out: the lowest rating of the 16 (4.1). Per-order fees add up fast on the pay-as-you-go plan.

After-Payment Apps (Every Plan Except Starter)

These four work after the shopper pays, and one also covers the cart. That makes them the safest start for a store that is not on Plus. Our post-purchase app list goes deeper on this group.

13. Essential Upsell & Cross Sell

Best for: a free start that also covers the product page and cart.

• Rating: 5.0 from 2,484 reviews. Built for Shopify. Made by Essential Bundles & Upsells.
• Price: free up to $100 of extra sales a month. Starter $9.99 (up to $500). Essential $19.99 (up to $1,000, adds cart page offers). Growth $39.99 (up to $2,500). 14-day trial on paid plans.
• Good: the free plan already includes product page and after-payment offers. It sits in Shopify's own checkout-upsell collection.
• Watch out: no payment-page offers, and the free plan stops at $100 of extra sales.

14. Kaching Post Purchase Upsell

Best for: the cheapest fixed monthly plan.

• Rating: 5.0 from 438 reviews. Built for Shopify. Made by Kaching Bundles & Upsells.
• Price: $4.99 a month for up to 99 orders. $7.99 for up to 199. $19.99 for up to 499. 14-day trial. Free only for development stores.
• Good: unlimited funnels, one-click upsells and downsells, and targeting by order value or UTM tag. Its site lists switch-to-subscription offers and A/B tests.
• Watch out: after payment only. No cart or payment-page offers.

15. AOV.ai Post Purchase Upsell

Best for: a free start with a clear cap.

• Rating: 4.9 from 171 reviews. Built for Shopify. On the App Store since January 2025.
• Price: free up to $200 of upsell sales in each 30 days. Paid plans run $19 to $59 a month, set by your Shopify plan. 7-day trial.
• Good: offers show after payment, on the thank-you page and on the order status page, in the shopper's language.
• Watch out: the free plan stops at $200 of upsell sales per 30 days. It is a newer app.

16. SMART Checkout Upsells & Rules

Best for: stores that want checkout rules and a free after-payment offer in one app.

• Rating: 5.0 from 849 reviews. Built for Shopify.
• Price: free (as read on November 1).
• Good: one-click post-purchase upsells and downsells, checkout banners and discount codes. It can also hide, sort or rename payment and shipping methods, and block risky orders.
• Watch out: a rules app first. Its upsells show after payment, not on the payment page. On the App Store since September 2024.

Also Checked

All 16 Apps Side by Side

• Twelve of the 16 carry the Built for Shopify badge. The four without it are ReConvert, Selleasy, AfterSell and CartHook. Three of the four apps with the most reviews (ReConvert, Selleasy and AfterSell) are in that group.
• Ratings are close. Fourteen of 16 sit between 4.8 and 5.0. Review counts say more about how proven an app is than the star score does.

What You Pay, and How the Bill Grows

Apps charge in four ways. This matters more than the starting price, so we did the math.

• By orders a month: Oxify, ReConvert, Candy Rack, Kaching Post Purchase, CartHook and AfterSell. Cheap when small, higher as you grow.
• By upsell sales: Zipify OCU, UpsellPlus, AOV.ai and Essential. The bill grows only when upsells earn. ReConvert's tiers read "store orders / upsell revenue," so check which it counts.
• By Shopify plan: AOV.ai's paid plans and Bold. Plus costs the most.
• Flat price, no order limit on the listing: Checkout Plus, Wiz, Checkout Components, Qikify and Selleasy. Better value at thousands of orders.

Price by orders a month

• Listed monthly prices, November 8, 2026. Payment-page rows show the plan that includes the offer, so they need Plus.
• "Not on the listing" means the App Store shows no plan for that many orders. Oxify's 1,500-order price is from our pricing page.
• CartHook is our math: 20 free orders, then $0.12 an order. At 1,500 orders it is the $49 plan plus $0.14 for each order over 1,000.
• AfterSell is our math from its billing doc: $34.99, plus $0.05 for each order above 500. At 1,500 orders that is $34.99 + 1,000 × $0.05 = $84.99. "Orders" means every store order in the last 30 days.

Price if you pay by upsell sales

These apps count the upsell sales they earn you. If your upsells earn $500 a month, none of the four costs more than $99.

Which Upsell Apps Work With Subscriptions and Checkout?

Seven of the 16 say they handle subscription offers. Six of those seven also list payment-page offers, which need Plus. Kaching Post Purchase is after payment only.

The table says "yes" only when the listing or the app maker's own page does. "Not stated" means we did not see it, not that the app lacks it.

Sources: the App Store plan cards and the app makers' own sites (upsellplus.com, zipify.com, aftersell.com, carthook.com, kachingappz.com, skailama.com, checkoutcomponents.com, digismoothie.com, upsell.com), read November 8, 2026. Oxify's own listing names A/B testing under analytics, with less detail than ReConvert or Zipify OCU.

What to check before you pick

• Match your subscription app. UpsellPlus names Appstle, Recharge and Seal. Zipify lists Recharge, Skio, Appstle and Loop. CartHook names Recharge and Seal. Bold Upsell works with Bold's own app.
• After payment, Shopify asks for a consent box. The shopper must agree that their payment method is saved for later orders. See Shopify's post-purchase subscription guide.
• Subscription upgrades on the payment page need Plus. Wiz lists them in its $99 Plus Growth plan.

Replacing Rebuy or UpCart on Plus? Cart Upsells, Free Gifts and A/B Tests

Say you run a Plus store and use Rebuy for cart upsells and free gifts. You want to A/B test them. These apps list the most of that, going only by what their pages state:

• AfterSell Pre-Purchase ($59.99) or Complete ($79.99): a cart with reward bars, free gifts, conditional upsells and A/B tests. Plus checkout upsells come with Post-Purchase and Complete.
• Zipify OCU (from $9.95): slide cart upsells, Plus checkout upsells, after-payment offers and A/B/C/D split tests in one plan. Free gifts are not stated.
• UpsellPlus ($119 Plus plan): cart rewards with free gifts, cart and checkout offers, and A/B tests with holdouts.
• ReConvert (free up to 50 orders): cart and checkout offers and built-in A/B testing. Free gifts are not stated.
• Oxify (ours, from $9.99): cart upsells, free gifts, reward bars and a checkout block on Plus. The listing names A/B testing under analytics, with less detail than ReConvert or Zipify OCU.

On profit: none of these pages say an A/B test picks the winner by profit. They talk about sales or conversion. Ask the app maker before you switch.

For a side-by-side, read our Rebuy alternatives guide. Moving off UpCart? See the UpCart alternatives.

"Free Plan" Can Mean "Free for Test Stores Only"

In the App Store search, many of these apps show "Free plan available" on their card. For five of them, the plan card says it only means development stores.

Free for development or staging stores only (what a live store pays):

• Checkout Plus: $19 a month to start.
• AfterSell: $34.99 a month.
• Kaching Post Purchase: $4.99 a month.
• Candy Rack: $29.99 a month.
• Zipify OCU: $9.95 a month.

Really free for a live store (with limits):

• SMART: free. Selleasy: unlimited orders, 5 campaigns.
• AOV.ai: up to $200 of upsell sales in each 30 days. Essential: up to $100 of extra sales a month.
• ReConvert: up to 50 orders or $50 of upsell sales. CartHook: 20 free orders a month.
• Qikify: free, but for checkout rules, not upsells.
• UpsellPlus is free to build, not to run. Going live starts with a trial, then $49 a month.

Free apps are still worth a test. Most paid apps above are free on a development store, so you can build a real offer before you pay.

Rules Every App Must Follow

These come from Shopify, not the app. Read them before you blame an app for a missing offer.

• The payment page needs Plus. Those extensions are "available only to stores on a Shopify Plus plan."
• After-payment offers work on every plan except Starter. Shopify still labels this feature beta.
• Only one app can run the after-payment page (you pick it in your checkout settings). A shopper can accept up to three offers per checkout.
• Some shoppers never see an after-payment offer:
  • Wallet and installment payments: Apple Pay, Google Pay, Amazon Pay, Klarna, Affirm and Afterpay.
  • Orders paid with a gift card, or with anything other than a credit card.
  • Local delivery orders, and orders under $0.50.
  • Orders with duties in more than one currency.
  • Orders that do not come from your Online Store channel.
• Some payment providers are out too: those that keep the card's security code, like Braintree, Payflow Pro, PayPal Payments Pro and Eway. See our payment methods guide.
• Shipping waits until the shopper reaches the order status page, or one hour after checkout.
• Payment-page offers: show two at most, with a button less bold than Pay now. Shopify says to place an offer outside the order summary.
• On phones, the order summary can hide an offer. In the usual multi-page checkout it starts folded, so an offer inside it stays hidden. In one-page checkout, Shopify's ORDER_SUMMARY4 spot sits below the Pay button on mobile instead.
• Some plans are locked. Since October 28, 2026, an app can require a store feature for a plan, such as checkout extensions on every step. A greyed-out Select button may mean your store does not meet it.
• Old code is gone. checkout.liquid no longer works on the information, shipping and payment steps. Script tags on thank-you and order status pages ended on August 28, 2025 for Plus and August 26, 2026 for other stores. Skip any app that asks you to paste code into checkout.

How to Add an After-Payment Offer Without Plus

This is the setup for any store on Basic, Grow or Advanced. The Shopify checkout upsell guide has the full walk-through.

1. Pick one app from the after-payment or all-in-one groups. Start on a development store if the app offers one free.
2. Build one offer: one product, a discount, and one short line of text.
3. Turn the app on in Shopify: Settings, then Checkout. If two apps are installed, choose one there.
4. Place a test order with a card. The offer should show, and accepting it should add the item to the same order.
5. Place a second test order with a wallet like Apple Pay. The offer should not show. That is how Shopify works, not a bug.

How to Write an After-Payment Offer

Shopify's UX guide for after-payment offers says to name the product and the discount, match your store's title and price, and skip exclamation points. It lists "Wait! Before time runs out!" as a thing not to write. Do not make the shopper doubt the order they just placed.

Sources: Shopify's UX guides for post-purchase and pre-purchase offers, read November 8, 2026. For examples, see how to write post-purchase offers that convert.

What to offer, by place:

• Payment page: a small add-on that fits the order, like gift wrap or shipping protection.
• Right after payment: a bigger extra, like a second unit, a refill or a related product at a small discount.
• Cart: a cheap add-on, or a nudge toward free shipping.

How to Pick in 4 Questions

1. Are you on Shopify Plus? Yes: look at apps 8 to 12, or an all-in-one app with a Plus plan. No: skip the payment-page apps and use the cart and the after-payment spot.
2. How many orders a month? Up to 100: Kaching Post Purchase ($4.99) or a free plan. From 101 to 500: order-based apps run $7.99 to $59.99. At 1,000 or more: one-price apps get cheaper for each order. See what you pay.
3. Do you sell subscriptions, or need A/B tests? Start with the subscriptions table. Then pick from Zipify OCU, AfterSell, UpsellPlus or Wiz.
4. Do you already use an after-payment app? Only one can run. Pick it first, then add a cart app that does not clash. Never sell the same product in two places.

Where Upsell Money Comes From

The only public comparison by place we found is from Growth Suite, an upsell app. It covers January to June 2026 and is the vendor's own data, so treat it as a rough guide.

• Offers accepted: cart 12% (250 stores), payment page on Plus 9% (28 stores), product page 7% (250 stores), after payment 6% (200 stores).
• Range: individual stores went from under 2% to over 20%.
• So: start with the cart, add the after-payment offer second, and treat the payment page as the last step.

A note from me. I'm Aditya, co-founder of Oxify. Our app reports upsell revenue by place, so here is what two of our stores show.

At Replenhair, the app earned £15,451 since install (read July 31, 2026): £8,742 from the cart drawer, £4,136 from the product page and £2,573 after payment. A UK merchant earned £1,200.34 in 30 days, all from product-page offers.

At these two stores, the payment page was not where the money came from. That is two stores and our own attribution, so treat it as an example, not a rule. Read the Replenhair case study.

Your First 7 Days With a Checkout Upsell

1. Day 1: pick the place and the app. Use the four questions above. Start a free plan or a trial.
2. Day 2: build one offer. One product, one short line, one button.
3. Day 3: test it like a shopper. Check your phone. Pay once with a card and once with a wallet. Wallets skip the after-payment page, so that is normal.
4. Days 4 to 6: leave it alone. Do not change the offer every day.
5. Day 7: read your numbers. How many said yes, how much extra each order earned, and whether checkout conversion, refunds or support tickets got worse than the week before.
6. Keep or cut. If the first two are up and the third is flat, keep it and add a second offer in a different place. If conversion fell, turn it off.

Check your last 50 orders for wallet and gift-card payments. Those shoppers will never see an after-payment offer, however good the app is.

Frequently Asked Questions

What to Do Next

• On Plus: add one small offer on the payment page, and remove the same product from your cart offer.
• Not on Plus: skip the payment page. Put a small add-on in the cart, and a bigger extra after payment.

From Oxify: Oxify Cart Drawer & Upsells covers the cart, product page, after-payment and thank-you offers, plus the checkout block on Plus. Start a 14-day free trial on the Shopify App Store. There is a 30-day refund if it does not pay for itself. See pricing.

• Who: published by Oxify, which makes Shopify upsell apps. We say so wherever our own app or data appears.
• Ratings and prices: on November 1, 2026 we copied each live App Store listing. On November 8 a script re-read them, and we updated every rating, review count and price that changed.
• Features: where an app shows offers comes from the November 1 reads, with plan cards re-read on November 8. Subscription and A/B claims come from listings and the app makers' own sites, read November 8.
• Other sources: Shopify rules come from Shopify.dev. Take rates are Growth Suite's. Store figures come from Oxify dashboards.
• What we did not do: install the other 15 apps. Our data held only the first lines of each plan card, so a feature lower down can be missed. "Not stated" means we did not see it.
