Best Shopify Cross-Sell Apps (2026)
The best Shopify cross-sell app in 2026 is Libautech Bundles & Upsell, our own app, because it covers every cross-sell surface, frequently bought together, product add-ons, cart popup and drawer offers, and post-purchase complements, from one dashboard with per-offer revenue analytics, and the AI builds the offer for you. Selleasy is the strongest free-to-install all-rounder, Essential Upsell & Cross Sell has the highest-rated free plan, Upsell.com (formerly ReConvert) is deepest on post-purchase, Rebuy is the rules engine for Plus-scale stores, and Shopify Search & Discovery is the free native starting point.
Key takeaways
- Cross-selling offers a complementary product (the belt with the trousers). Upselling offers a better version of the same product. Most apps here do both, but the cross-sell is where average order value grows fastest.
- We make Libautech Bundles & Upsell and rank it first, because it runs every cross-sell surface in one app and the AI drafts the offer, not just the product suggestion. Weigh that we have a commercial interest.
- The one number we are behind on is reviews: ours is the newest here at 35, while Essential sits at a 5.0 across 2,000-plus, Selleasy at a 4.9 across 2,478, and Upsell.com at a 4.8 across more than 2,700. We say so, and name the better fit for each job below.
- The highest-converting cross-sell is one click, in place, and complementary. A cross-sell that opens a new product page mostly fails.

What cross-selling is, and how it differs from upselling
A cross-sell offers a complementary product alongside the one the shopper is buying: the belt with the trousers, the filters with the coffee maker. An upsell offers a better or larger version of the same product: the 1kg bag instead of the 250g. Cross-selling grows the order by adding items; upselling grows it by trading up. Most apps on this list do both, but cross-selling is usually where average order value moves fastest, because a good complement joins a decision the shopper has already made.
On the product page a cross-sell takes three main forms: a frequently bought together block with a combined add to cart, individual add-on checkboxes below the buy button, and a related products carousel. The one that matters is whichever the shopper can accept with a single click. A cross-sell that opens a new product page and restarts the decision mostly does not convert.
Who needs a cross-sell app, and who does not
A cross-sell app earns its keep when you have complements to pair. If your catalog is single hero products with nothing that goes with them, it is premature. Match yourself to a row before you install anything.
| Your store | Best first move | Why |
|---|---|---|
| Growing store, no offers yet | AI offer creation | Let the AI build the pairing, discount and placement so you launch in minutes. |
| Tight budget, wants proof first | A free plan or free-to-install app | Prove cross-sells earn before you pay a monthly fee. |
| Hundreds of SKUs, a team | A rules and personalization engine | Manual pairing is impractical; a rules engine ranks per shopper, if someone owns it. |
| Post-purchase is the priority | A thank-you-page specialist | Cross-sells after payment add revenue at zero risk to the original order. |
How we ranked these, and a word on bias
The disclosure first. We make Libautech Bundles & Upsell, and we rank it first, so read this with that in mind. We rank it first because it runs every cross-sell surface, product page, cart and post-purchase, in one app, and because the AI drafts the finished offer rather than only suggesting a product. On the cross-sell features themselves the specialists are strong, and where it is behind is public proof: ours is the newest app here at 35 reviews, while Essential, Selleasy and Upsell.com each have thousands. We name the better fit for each job in the best app for each situation section, and our figures are read from the live App Store listing, same as everyone's.
The five criteria we score on: does it create the offer or only suggest products; how many cross-sell surfaces it covers; is it fast and native on the product page; what it costs at real volume, including any revenue-share fee; and how much setup it demands. Ratings and review counts are from the Shopify App Store as of August 2026.

1. Libautech Bundles & Upsell
Bundles & Upsell (our app, 4.9 across 35 reviews, Built for Shopify) covers every cross-sell surface from one dashboard: frequently bought together pairings with a combined one-click add, product add-ons shown as optional extras below the buy button, cart popup and drawer offers, and post-purchase complements. The AI reads your catalog and order history and produces a finished, editable offer, the pairing, the discount and the placement, so setup is minutes, not hours. Every offer's revenue is tracked separately, and setup is AI-assisted through Claude.
Strengths: one app across every surface means you are not stacking three cross-sell apps that each inject their own scripts, and the AI drafts the offer rather than leaving you to build it.
Watch-outs: we will be straight, it has the smallest review base here at 35, because it is the newest app on this list, so it has less public proof than Essential's or Selleasy's thousands.
Best for: stores that want cross-sells live in under 15 minutes with AI doing the offer construction, and room to expand across the journey without switching apps.
2. Selleasy
Selleasy (4.9 across roughly 2,478 reviews, Built for Shopify) covers frequently bought together, product add-ons and in-cart cross-sells, and it is free to install, so a growing store can run real cross-sells before paying a monthly fee.
Strengths: excellent value and a deep, positive review base, with all the core cross-sell surfaces in one app.
Watch-outs: the AI suggests products but you build the offers, and the interface is functional rather than polished.
Best for: value-focused stores that want a proven all-rounder. Free to install, paid plans from $9 a month.
3. Essential Upsell & Cross Sell
Essential (5.0 across more than 2,199 reviews, Built for Shopify) pairs a genuine free plan with the highest rating on this list, covering product page, cart and post-purchase cross-sells.
Strengths: the best free starting point on this list, with a near-perfect rating and room to grow into paid tiers.
Watch-outs: like the other specialists it recommends and displays, but does not draft the whole offer for you.
Best for: stores that want the strongest free plan and a proven track record. Free plan, then from $9.99 a month.
4. Upsell.com (formerly ReConvert)
Upsell.com (4.8 across more than 2,700 reviews, Built for Shopify) is the most-proven app on this list and the strongest on the thank-you page, where one-click cross-sells and reorders run after payment at zero risk to the original sale.
Strengths: the deepest track record here, and post-purchase cross-sells that cannot cost you the sale.
Watch-outs: its center of gravity is post-purchase, not the on-page cross-sell moment. Some tiers add a fee on generated revenue.
Best for: stores building around the thank-you page. Free plan, then from $4.99 a month.
5. Rebuy
Rebuy (4.7 across 741 reviews) is an AI rules engine that personalizes cross-sells across product pages, cart, checkout and post-purchase, with deep data integrations. The personalization is powerful, but the offers are configured through its rules engine, and that takes real time.
Strengths: strong personalization at scale for catalogs with hundreds of products where manual pairing is impractical.
Watch-outs: it rewards a team member who owns the setup, and it does not carry the Built for Shopify badge. Pricing scales with order volume.
Best for: high-volume and Shopify Plus stores with someone to own the tool. From $25 a month.
6. Shopify Search & Discovery
Shopify's own free app (2.8 across 455 reviews) lets you manually define complementary products that render in your theme's recommendation sections. No AI pairing and no combined add to cart, but the price is zero and the integration is native.
Strengths: free, official and enough for a small catalog where you personally know which products pair.
Watch-outs: manual placement only, no combined add-to-cart, no offer analytics. The modest rating reflects merchants expecting more automation.
Best for: new stores validating whether cross-sells move the needle before paying for automation.
The best app for each situation
Best all-in-one, AI builds the offers: Libautech Bundles & Upsell, our app, for every cross-sell surface in one place.
Best free-to-install all-rounder: Selleasy, for proven cross-sells before you pay.
Best free plan: Essential Upsell & Cross Sell, the highest-rated on this list.

Best free native start: Shopify Search & Discovery, to validate before paying.
Which cross-sell app is right for you?
Pick what matters most and we will point you to the best fit. Often it is not ours, and we say so.
Where cross-sells convert best
Placement decides acceptance as much as the pairing does. Shopify's own product recommendations render complementary items natively, which is a good baseline, but the surfaces below are where a cross-sell earns.
Add-ons go directly below the add to cart button. That is where a shopper looks after deciding on the main item, so an optional complement reads as helpful.
Frequently bought together blocks go below the product description. Close enough to catch the shopper still evaluating, far enough not to fight the buy decision.
Cart offers catch the shopper who skipped the page. A single complementary add in the cart drawer is a second, contextual chance without a hard interruption.
Post-purchase cross-sells add revenue at zero risk. On the thank-you page the sale is already banked, so a relevant complement can only add.
Common cross-sell mistakes
Cross-selling a random bestseller. A complement that ignores the viewed product reads as noise. Pairings should come from order history or a deliberate rule.
Sending the shopper to a new page. A cross-sell that restarts the decision elsewhere mostly fails. Keep the add one click, in place.
Offering too many at once. One to three complements. Acceptance drops as options grow, because choice becomes a comparison task instead of a yes-or-no add.
Ignoring the pricing model. A revenue-share fee looks small at launch and compounds as the cross-sell works. Prefer flat tiers unless the share is genuinely small at your volume.
What your cross-sells are worth
Put in your monthly orders, the share of shoppers who accept a cross-sell, and what an accepted item adds. The calculator shows the extra revenue a cross-sell program adds, monthly and yearly.
Extra revenue a month
$880
Extra revenue a year
$10,560
That is about 40 accepted cross-sells a month at $22 each, spread as an average order value lift of about $2 across every order. It is gross added revenue before any offer discount, and it only holds if the cross-sell created the bigger order rather than discounting one that would have happened anyway. You can run cross-sell offers from Bundles & Upsell.
