Best Shopify Upsell and Cross-Sell Apps in 2026
Last verified: October 23, 2026
All three apps here sell on the same promise, more revenue per order, but they meter and place that revenue differently: Frequently Bought Together charges a flat fee by order count for product-page bundles only, Candy Rack charges a flat fee by order count across 8 placements from product page to post-purchase, and Zipify OneClickUpsell charges by the upsell revenue it generates and is built around a one-click post-purchase recharge. Five other well-known apps in this category, ReConvert, AfterSell, UpCart, Rebuy, and Selleasy, are not currently installable on the Shopify App Store, which is why none of them made this list.
ToolsGavel's top pick: Frequently Bought Together (4.5/5, from $9.99/mo) — Frequently Bought Together has the deepest review base in this category by a wide margin, 1,212 reviews at 4.9 out of 5 on the Shopify App Store, backed by a free Starter plan that never expires and a $9.99/mo entry price for the cheapest paid tier. It only places offers on the product page, not in the cart or at checkout, and recurring low-rated reviews point to manual bundles being confusing to set up. The developer, Code Black Belt, is owned by Shop Circle, a Shopify-app portfolio company, worth knowing if an independent indie app matters to you. The vendor's own site lists a conflicting '$19.99/mo' starting price with no breakdown, almost double the App Store's $9.99, so go by the App Store number when budgeting.

Frequently Bought Together Best overall ★★★★★ ★★★★★ 4.5

Best for: Stores that want product-page bundles and cross-sell widgets with a genuine free tier, and don't mind buying from a Shop Circle-owned brand instead of an independent indie app · from $9.99/mo
2
Candy Rack Best all-in-one cart and checkout upsells ★★★★★ ★★★★★ 4.4
Candy Rack covers 8 upsell placements in one app, including the product page, a slide cart drawer, a cart-page pop-up, checkout (Shopify Plus only), post-purchase and thank-you pages, on a flat monthly fee tied to order volume with an explicit no-revenue-share policy. It ties Frequently Bought Together's 4.9-star rating on a smaller review base of 265, and backs every plan with a 60-day money-back guarantee. The catch: there's no permanent free plan for a live store, pricing starts at $29.99/mo once the 8-day trial ends, the shortest trial of the three apps here. A/B testing also isn't native; it needs a separate Intelligems integration for pre-checkout offers.
Best for: Stores that want upsells covering product page, cart, checkout, and post-purchase in one app, and that are fine paying a flat fee from day one with no permanent free tier · from $29.99/mo
3
Zipify OneClickUpsell Best for one-click post-purchase upsells ★★★★★ ★★★★★ 4.1
Zipify OneClickUpsell is built around one-click post-purchase upsells, recharging a customer's already-used payment method with no card re-entry, and it is the only app here with native A/B testing and Shopify Plus checkout-extensibility upsells. Pricing starts at $9.95/mo and scales automatically with the upsell revenue it generates, capping at $999/mo, with a 30-day free trial, the longest of the three. The catch is rating and reliability: at 4.6 out of 5 from 569 reviews, it's the lowest-rated app here, and a real cluster of 1-star reviews describes upsell payments not being captured, duplicate orders, and a promotion activated without merchant consent. Cost complaints also turn up once a store scales past the entry tier, since the revenue-linked pricing has no flat-fee ceiling until $999/mo.
Best for: Shopify Plus stores that specifically want checkout-extensibility upsells and a true one-click post-purchase recharge, and that are comfortable with revenue-linked pricing that can climb toward $999/mo · from $9.95/mo
What each app meters, and where it places offers
Frequently Bought Together and Candy Rack both charge a flat monthly fee by order count, climbing through fixed tiers as a store’s monthly order volume grows, with neither one taking a cut of the extra revenue an upsell actually generates. Zipify OneClickUpsell works differently: it runs one “Unlimited” plan whose price scales automatically with the upsell revenue the app generates for a store, from $9.95/mo up to a $999/mo cap, so a bigger upsell month means a bigger bill even if order count stays flat.
Where each app places its offers matters just as much as how it charges for them. Frequently Bought Together is a product-page specialist only, bundle and cross-sell widgets in up to 4 preset locations plus a custom slot, with no cart, checkout, or post-purchase placement at all. Candy Rack covers the most ground, 8 placements from the product page through a built-in slide cart drawer, a cart-page pop-up, a Shopify Plus-only checkout embedded offer, and on to post-purchase and thank-you pages. Zipify OneClickUpsell covers product page, cart, and thank-you placements too, but its signature move is a one-click post-purchase upsell that recharges a customer’s already-used payment method with no card re-entry, plus its own Shopify Plus-only in-checkout upsells.
| App | Meters | Cheapest paid entry | Free plan / trial | Where it places offers |
|---|
| Frequently Bought Together | Monthly order count, flat fee | $9.99/mo (≤50 orders/mo) | Free Starter plan forever; 14-day trial on paid | Product page only |
| Candy Rack | Monthly order count, flat fee, no revenue share | $29.99/mo (0-50 orders/mo) | Dev/trial stores only; 8-day trial on paid | Product page, cart drawer, cart pop-up, checkout (Plus only), post-purchase, thank-you |
| Zipify OneClickUpsell | Upsell revenue generated, scales automatically | $9.95/mo (up to $200/mo in upsell earnings, per the App Store) | Dev/partner stores only; 30-day trial | Product page, cart, in-checkout (Plus only), one-click post-purchase, thank-you |
A dated note on apps that aren’t rankable right now
As of October 23, 2026, several other well-known Shopify upsell apps are not available to new stores. ReConvert, AfterSell, and UpCart all show “This app is not currently available on the Shopify App Store” on their listing pages, and the Rebuy Personalization Engine and Selleasy listings are also not currently installable. We found no published reason from Shopify or the developers for the ReConvert, AfterSell, UpCart or Rebuy delistings. Because a store can’t act on a recommendation it can’t install, none of these five apps made this guide, no matter how they rated in the past.
Which one to pick
A store that just wants “customers also bought” widgets on product pages, and wants to start free while testing whether bundling moves average order value, gets the most mileage out of Frequently Bought Together. A store that wants upsells running through the whole funnel, cart drawer, checkout, and post-purchase, in one app with a predictable flat fee should start with Candy Rack, especially if Shopify Plus’s checkout-extensibility isn’t a requirement yet. A store that specifically wants a one-click post-purchase recharge, or native A/B testing without a third-party add-on, fits Zipify OneClickUpsell better, as long as the revenue-linked pricing is budgeted against the store’s actual upsell earnings rather than assumed to stay near the $9.95 entry price.
How we picked
Every price, rating, and review quote in this guide came from the live Shopify App Store listing for each app, checked directly on October 23, 2026, cross-referenced against each developer’s own pricing page where one exists. Where the App Store listing and a vendor’s own site disagreed on a number, both versions are disclosed in the individual app reviews rather than silently picking one. Ranking is editorial: ToolsGavel may earn a commission if you sign up through a link on this page, and that never changes which app ranks where.

Frequently asked questions
What's the best Shopify upsell app overall?
Frequently Bought Together, for most stores. It has the deepest review base of any app in this category, 1,212 reviews at 4.9 out of 5 on the Shopify App Store, a free Starter plan that never expires, and the cheapest confirmed paid entry price at $9.99/mo. It only covers the product page, though, so a store that wants cart, checkout, or post-purchase offers needs Candy Rack or Zipify OneClickUpsell alongside it, or instead.
Do Shopify upsell apps charge by order volume or by revenue?
Both models exist in this category, and they produce very different bills as a store grows. Frequently Bought Together and Candy Rack both charge a flat monthly fee tied to order count, with no revenue share, so a strong upsell month doesn't push the bill up on its own. Zipify OneClickUpsell instead scales its single plan automatically with the upsell revenue it generates, starting at $9.95/mo and capping at $999/mo, the pricing model behind several of its own reviewers' complaints about cost once a store scales past the entry tier.
Which Shopify upsell app works at checkout on Shopify Plus?
Two of the three. Candy Rack offers a checkout embedded offer that requires Shopify Plus, while every other placement works on any plan. Zipify OneClickUpsell requires Shopify Plus specifically for its in-checkout upsells, on top of a true one-click post-purchase recharge that doesn't need Plus at all. Frequently Bought Together doesn't place offers at checkout; it's a product-page specialist only.
Why isn't ReConvert, AfterSell, Rebuy, UpCart, or Selleasy on this list?
None of the five can be installed by a new store right now. ReConvert, AfterSell, and UpCart all show 'This app is not currently available on the Shopify App Store' on their listing pages, as of October 23, 2026, and Rebuy Personalization Engine and Selleasy are also not currently installable. We found no published reason from Shopify or the developers for the ReConvert, AfterSell, UpCart or Rebuy delistings. Recommending an app a reader can't actually install would be misleading, so this guide only ranks apps confirmed live on the Shopify App Store.
