What is the best upsell app for ecommerce in 2026?

ReConvert, built by Upsell.com in New York since 2018, is the most reviewed app in this list with 3,128 reviews on the Shopify App Store. It covers the product page, the cart, the one-click post-purchase offer, the thank-you page and the order status page. AI recommendations, frequently-bought-together bundles and A/B tests come with every plan.

Pricing needs care, because two official grids coexist. The Shopify App Store listing, which is what bills you, shows a free plan up to 50 orders or $50 of upsell revenue, then $9.99 up to 100 orders, $19.99 up to 200 and $39.99 up to 500. The vendor's own site shows Growth free up to 2,000 orders, then Scale from $299. Check the plan offered at install: that is the one you will pay. Either way, the basis is the higher of two numbers, your orders or your upsell revenue. Plenty of roundups still show the old $4.99 plus 0.75% plan, which no longer exists.

One-star reviews describe charges after uninstalling or after the trial, automatic moves to a higher tier, and refused refunds. One merchant says the app made $40 while costing $150. Others report offers from other brands showing up without consent.

Candy Rack, from Digismoothie in Prague, bets on the moment a shopper clicks add to cart. A pop-up offers the accessory, the extended warranty or the upgrade. It covers eight placements in total across product page, cart, checkout and post-purchase. The cart drawer is included, so are quantity discounts, and the storefront runs in 13 languages.

Pricing follows online orders: $29.99 up to 50, $39.99 up to 200, $59.99 up to 500. There is no free plan for a live store. Upsell revenue is never billed, though, and Digismoothie refunds within 60 days: the longest guarantee in this ranking. AI mode, powered by Gemini, picks products, and A/B tests run through Intelligems.

The catch: Digismoothie also publishes one of the best-ranked upsell roundups, which puts Candy Rack first. Nothing wrong with that, but read it knowing who wrote it. Negative reviews mostly target the free plan terms, which only apply to development stores.

Zipify OneClickUpsell, or OCU, comes from Zipify, the US maker of Shopify sales pages. Its home turf is the one-click offer right after checkout, with funnels: if the buyer says no, a cheaper downsell steps in. It also covers the cart, product page, cart drawer, thank-you page and, on Shopify Plus, the checkout itself.

Its grid is the fairest here on one point: order volume is never billed. You pay $9.95 a month while upsells bring in under $200, $25 up to $2,500, then $149 rising with revenue, never above $999. If nobody accepts your offers, you pay the minimum. It plugs into Klaviyo, Omnisend, Recharge and Skio.

One-star reviews report offers that never fire, upsell payments not captured, duplicate orders, and a free-shipping promo switched on without warning. Larger stores call it too expensive once revenue climbs. One merchant says they paid for three years with zero revenue: uninstall what you no longer use.

Frequently Bought Together, by Code Black Belt, uses a recipe every shopper knows: under the product, two or three items others bought with it, a checkbox and a discount. The app's AI learns pairings from your sales, and you can override them by hand. It has been around since 2017 and has 1,214 reviews.

Pricing is low and easy to read: free for three manual bundles, then $9.99 a month up to 50 orders, $24.99 up to 500 and $39.99 above. Four discount types are available: percentage, fixed amount, free item or free shipping. Ratings from Judge.me, Loox or Yotpo show inside the bundle, which builds trust.

The limit is clear: no post-purchase offer and no checkout placement. It is a product page and cart tool. If you want post-purchase too, you need a second app and a second bill.

Selleasy, by Logbase, is the most generous app on paper: its free plan allows unlimited orders and five campaigns. Paid plans never count orders either. Starter at $9 unlocks unlimited campaigns, Pro at $29 adds in-checkout offers for Shopify Plus, and Max at $59 adds a rules engine. Paying yearly saves around 15%.

It covers the product page (add-ons and frequently bought together), cart and cart drawer, the one-click post-purchase offer and the thank-you page. It has 2,765 reviews.

A security incident hit the app in 2026. Someone gained access to an internal vendor tool and injected a script that sent shoppers to a fake payment page. Logbase says it removed the script and locked the custom JavaScript setting. The app can be installed again. Some merchants left over how the incident was handled.

On WordPress, FunnelKit is the most complete upsell plugin. It swaps WooCommerce's checkout for its own, adds an order bump right before payment, then the one-click post-purchase offer. Rules decide which shopper sees which offer. More than fifteen gateways support the single click, including Stripe, PayPal, Mollie and Braintree.

You pay yearly with no percentage on sales. Watch the entry plan: Basic, at $99.50 a year on sale, does not include one-click upsells. You need Plus, $149.50 a year on sale ($299 full price), about $12.50 a month. Professional and Elite add email automation and more sites.

The catch: you now own your checkout. A WooCommerce, theme or gateway update can break the funnel, and someone has to watch it. The sale prices on the page do not state the renewal rate: ask before you pay.

AfterSell launched in 2019 in Vancouver and has belonged to Rokt since 2024. It is the reference for one-click post-purchase offers: smart funnels with a downsell, a custom thank-you page, multivariate tests. The Pre-Purchase plan adds a cart drawer, product page offers and a free-shipping progress bar. Merchants rate it 4.9 across 1,113 reviews.

The price takes some math. Post-Purchase is $34.99 a month, then $0.05 per order past 500. That is $109.99 at 2,000 orders. And every order in your store counts, not just those that saw an offer. Rokt Thanks shows other brands' offers on your thank-you page: on the Earn & Save plan, what it earns comes off your AfterSell bill.

One-star reviews talk money: a $267.05 bill in one month from a per-order fee the merchant had not understood, years paid without use, a price hike without notice. They also talk payments: Apple Pay and Google Pay buyers never see the offer, and neither do multi-currency stores.

UpCart, from the same Rokt group as AfterSell, does one thing: it replaces the Shopify cart with a slide-out drawer. Inside: cross-sells picked by AI or rules, a rewards bar with up to four tiers (free shipping, discount, gift), one-click add-ons like shipping protection, and an automatic free gift. The design module goes all the way to custom code.

Every feature is on every plan. Only order count changes the price: $29.99 up to 200, $34.99 up to 500, $89.99 from 1,001 to 2,000, and up to $199.99 past 5,000. Here too, every store order counts.

Negative reviews mention charges after uninstalling, an annoying cart zoom on iPhone, duplicated gifts, add-to-cart events not reaching Klaviyo, and a clash with Shopify's latest default theme. Support starts with a bot.

PrestaShop has no one-click post-purchase offer like Shopify. HiPresta's Upsell & Cross Selling PRO module covers the rest: recommended product lists per product, cart blocks, a pop-up after add to cart, a cart drawer and, most useful, an offer page shown right before payment.

You pay €97.99 once and that is it: no subscription, no per-order fee. Percentage or fixed discounts are built in. It runs on PrestaShop 1.7, 8 and 9. The vendor site does not say whether the price includes VAT, so ask first.

Two limits. The pre-payment offer page shows once per cart, tracked by a browser cookie: a buyer who declines will not see it again. And there is no AI: you set the pairings yourself.
