14 Best Shopify Cross-Sell Apps: Free & Paid (Sept 2026)

Best Shopify Cross-Sell Apps

Short answer: There is no single best Shopify cross-sell app, because the right pick depends on where the offer appears. For the cart drawer it is Oxify Cart Drawer & Upsell (4.9, Built for Shopify, from $9.99/mo). For product-page "frequently bought together" it is Selleasy (free to 50 orders/mo) or Frequently Bought Together CBB. For one-click post-purchase offers and Shopify Plus checkout blocks it is AfterSell, and for a dedicated thank-you page it is Upsell.com ‑ ReConvert from $4.99/mo. Every rating, review count and price below was pulled from the Shopify App Store on 2 September 2026.

Key Facts (Verified September 2026)

  • Shopify's free Search & Discovery app lets you hand-pick up to 10 complementary products per product. They render as a block in the product-information section of compatible themes only, and there is no cart, checkout or post-purchase placement.
  • App blocks on the checkout information, shipping and payment pages are Shopify Plus only. Thank-you page, order-status page and post-purchase app extensions work on Basic Shopify or higher.
  • A shopper can accept at most three post-purchase offers per checkout, and the post-purchase page is skipped when they pay with a wallet or installment service (Apple Pay, Google Pay, Amazon Pay, Klarna, Affirm, Afterpay) or a gift card.
  • Nine of the 14 apps carry the Built for Shopify badge as of 2 September 2026; Wiser AI, ReConvert, Honeycomb, Rebuy and LimeSpot do not. The badge requires, among other things, that the app costs your storefront no more than 10 Lighthouse performance points.
  • The "free" cross-sell apps are free with real ceilings: Selleasy and Wiser AI stop at 50 orders/month, Essential at $100 of extra revenue, Honeycomb at 100 funnel views/month, LimeSpot at 10 orders/month, FBT CBB at 3 manual bundles, and BOGOS at 30 orders total. Details in the free-plan section below.

How this list was built

Each app was opened on the Shopify App Store on 2 September 2026 and the rating, review count, plan ladder, trial length and Built for Shopify badge were read from the live listing. Older roundups (including the May 2026 version of this page) quoted review counts that have since changed, and one app in that version, Nosto, now lists as "free to install" with a separately billed Nosto account, so it has been replaced.

Placement is the organising idea here. A cross-sell can sit on the product page, in the cart drawer, on the checkout pages (Plus only), on the post-purchase page between payment and confirmation, or on the thank-you page. Most apps do two or three of those well and the rest badly, which is why the quick table below carries a "best for" column instead of a rank. If you are still deciding between a bundle, a cross-sell and a related-products widget, read FBT vs cross-sell vs related products first.

Best Shopify cross-sell apps at a glance (verified 2 September 2026)

"From price" is the cheapest paid plan on the listing. "Free plan" states the real ceiling, because several apps advertise a free plan that only applies to development stores.

Which placements each app covers

"Checkout" means app blocks on the information, shipping and payment pages, which Shopify only allows on Plus. "Cart" covers a cart drawer or cart page widget; the per-app sections say which. "Post-purchase" means the one-click page between payment and the thank-you page.

The 14 apps, one by one

1. Oxify Cart Drawer & Upsell — best for the cart drawer

Rating: 4.9 (37 reviews) · Built for Shopify: yes · Pricing: $9.99/mo for 0–100 monthly store orders, $19.99 (101–200), $29.99 (201–500), $49.99 (501–1,000), $79.99 (1,001–2,000), $99.99 (2,001–3,000), $149.99 (3,000+), optional $299/mo Enterprise · 14-day free trial

Oxify Cart Drawer & Upsell cross-sell widgets in the cart drawer and post-purchase page

What it does best: cross-sells inside a slide-out cart drawer. The drawer carries an upsell and cross-sell module with frequently-bought-together logic, product add-ons (shipping protection, warranty, gift wrap), an in-cart subscription upgrade, free gift with purchase, BOGO and volume discounts, and a rewards progress bar, so the offer sits next to the checkout button instead of on a separate page.

Placements: product page widgets, cart drawer, checkout upsell (Plus), one-click post-purchase, thank-you page. Pricing gates: none. Every plan has every feature; the ladder is priced purely by monthly store orders.

Honest limitation: 37 reviews is a young listing next to Selleasy's 2,541, and order-based pricing means a store past 3,000 orders a month pays $149.99 where Selleasy charges $29. If the cart drawer is not your main placement, a cheaper single-placement tool may do.

Pick it if: the cart drawer is where you want cross-sells to live and you would rather run one app than four. Setup steps are in how to add upsells to a Shopify cart drawer, and the feature page is at Shopify cart drawer upsell.

2. Upsell & Cross Sell — Selleasy — best cheap all-rounder for product pages

Rating: 4.9 (2,541 reviews) · Built for Shopify: yes · Pricing: free to install up to 50 orders/mo, $9/mo up to 500, $19/mo up to 1,000, $29/mo above 1,000 · 30-day free trial

Selleasy frequently bought together and add-on widgets

What it does best: Amazon-style "frequently bought together" and add-on offers on the product page, shown as a list, grid, carousel or pop-up, with the same offers reusable in the cart drawer and as a pop-up cart funnel.

Placements: product page, cart drawer or cart page, checkout upsell blocks (Plus), post-purchase, thank-you and order-status page. Pricing gates: none by feature. All four tiers list the same features (product and cart upsells, post-purchase and thank-you upsells, 50 free AI recommendations, a free setup call); only the order ceiling changes.

Honest limitation: the ceilings count your store's total orders, not orders that contained an upsell, so a 600-order store is on the $19 plan even if only 40 orders took an offer.

Pick it if: you want product-page cross-sells for free or near-free and can live with manual pairings. If you have outgrown it, Selleasy alternatives compares the usual next steps.

3. Essential Upsell & Cross Sell — best free product-page offers

Rating: 5.0 (2,259 reviews) · Built for Shopify: yes · Pricing: free up to $100 of attributed extra revenue, Starter $9.99/mo (up to $500), Essential $19.99/mo (up to $1,000, adds cart offers), Professional $39.99/mo (unlimited) · 14-day free trial

Essential Upsell & Cross Sell product page widgets

What it does best: quick product-page cross-sells: frequently bought together, related products, one-click add-ons and BOGO-style bundles with automatic discounts, plus a one-click post-purchase offer.

Placements: product page, post-purchase, and cart drawer from the $19.99 plan. No checkout blocks and no thank-you page widget are listed. Pricing gates: the ladder is metered on revenue the app attributes to itself, and cart-drawer offers are held back until the $19.99 tier.

Honest limitation: "free" ends at $100 of attributed revenue, which a store with steady traffic can hit in a week, so treat the free plan as an extended trial.

Pick it if: you are launching and want product-page FBT with zero fixed cost, and you expect to move to the $9.99 or $19.99 tier once offers convert.

4. Frequently Bought Together CBB — best pure FBT widget

Rating: 4.8 (1,049 reviews) · Built for Shopify: yes · Pricing: Starter free (3 manual bundles), Professional I $14.99/mo (up to 50 orders/mo), Professional II $19.99/mo (up to 500), Professional III $39.99/mo (500+) · 14-day free trial

Frequently Bought Together CBB product page bundle widget

What it does best: the Amazon-style "frequently bought together" block, built from your order history with manual overrides and global presets, four discount types (percentage, fixed, free item, free shipping) and review stars pulled from Judge.me, Loox, Yotpo and others.

Placements: product page only. Pricing gates: the free plan is limited to 3 manual bundles with basic widget styling and no automatic recommendations. Every paid tier has the full set (unlimited bundles, automatic and global recommendations, bundle discounts, analytics, translations); only the order ceiling changes.

Honest limitation: nothing outside the product page. No cart, checkout, post-purchase or thank-you placement, so you will pair it with a second app for everything after "add to cart".

Pick it if: you already have a cart drawer and want the strongest single FBT block. More options in the frequently bought together apps roundup.

5. Candy Rack — best one-click pop-up offers

Rating: 4.9 (223 reviews) · Built for Shopify: yes · Pricing: Lite $29.99/mo (0–50 online-store orders), Starter $39.99/mo (51–200), Growth $59.99/mo (201–500); tiers above 500 are not published on the listing · 8-day free trial, 60-day money-back guarantee

Candy Rack one-click upsell pop-up

What it does best: a pop-up of one-click offers the moment a shopper hits "add to cart", with a built-in slide cart carrying offers and rewards. The listing now advertises an AI mode (Candy Rack AI or Google Gemini chooses the offers), tiered volume bundles on the product page, and A/B testing through Intelligems.

Placements: product page, its own slide cart, checkout (Plus), post-purchase, thank-you page. Pricing gates: none by feature; every tier lists unlimited upsell orders and revenue, tailored design and 24/7 chat.

Honest limitation: a $29.99 floor even for a store doing 20 orders a month, no free plan for live stores, and no published price past 500 orders.

Pick it if: the product-page pop-up is the placement you want and design polish matters more than the entry price.

6. Wiser AI ‑ Upsell & Cross Sell — best AI recommendations with a free tier

Rating: 4.9 (513 reviews) · Built for Shopify: no · Pricing: free to install for 0–50 monthly orders, Basic $9/mo (51–100), Growth $19/mo (101–300), Premium $49/mo (301–500); above 500 not published on the listing · 14-day free trial

What it does best: recommendation widgets driven by order data: AI frequently-bought-together with bundle discounts, "also bought", related products by tags and metafields, best sellers and new arrivals that update themselves, plus a cart drawer with tiered discounts and a rewards bar.

Placements: product page, cart drawer, checkout upsell (Plus), post-purchase, thank-you and order-status page. Pricing gates: none; all four tiers list identical features and differ only by order ceiling.

Honest limitation: no Built for Shopify badge, and the ladder steepens at the top: $49 for 301–500 orders is five times Selleasy's price for the same volume. There is no published tier for stores above 500 orders.

Pick it if: you have under 50 orders a month and want automatic, data-driven picks instead of hand-built pairings.

7. Upcart — best for cart-drawer design control

Rating: 4.7 (875 reviews) · Built for Shopify: yes · Pricing: $29.99/mo (0–200 orders), $34.99/mo (201–500), $54.99/mo (501–1,000); above 1,000 not published; free for development stores only · 14-day free trial

What it does best: a cart drawer you can rebuild from scratch. Templates accept custom HTML, CSS and JSX, and the modules cover upsells for frequently bought items, add-ons (shipping protection, warranties), a rewards and free-shipping bar, announcements, in-cart discounts and free gifts.

Placements: cart drawer only. Pricing gates: none; all three tiers list the same six modules.

Honest limitation: nothing before or after the cart. No product-page widget, no checkout blocks, no post-purchase or thank-you page, so Upcart is a two-app stack by design (it lists AfterSell, from the same developer, Rokt, as its post-purchase partner).

Pick it if: your developer wants full control over the drawer markup and you are happy to add a post-purchase app. See Upcart alternatives if the floor price is the sticking point.

8. Upsell.com ‑ ReConvert Upsell — best thank-you page builder

Rating: 4.8 (2,810 reviews) · Built for Shopify: no · Pricing: free for development stores only; Upsell Basic $4.99/mo (up to 50 orders or $50 of upsell revenue), Upsell Growth $9.99/mo (100 orders or $100), Upsell Business $19.99/mo (200 orders or $200); higher tiers sit on the developer's full pricing table, not the listing · 14-day free trial

Upsell.com ReConvert thank-you page and post-purchase funnel builder

What it does best: the thank-you and order-status page. The drag-and-drop editor adds one-click cross-sells, surveys, reorder buttons and birthday collectors after payment, and the same app now covers product-page AI recommendations, cart upsells and checkout blocks on Plus.

Placements: product page, cart, checkout (Plus), post-purchase, thank-you and order-status page. Pricing gates: none by feature; every listed tier includes A/B testing, AI recommendations, the full funnel and segmentation. The tier is set by whichever ceiling you hit first, orders or upsell revenue.

Honest limitation: the "free plan" on the listing is for development stores. Because the meter is orders or upsell revenue, a store at 150 orders that earns $300 from offers is already above the $19.99 tier, and the price for that is not on the App Store page. No Built for Shopify badge.

Pick it if: you want the richest post-payment page for the lowest entry price. Compare it with the other options in best Shopify thank-you page apps.

9. Aftersell Post Purchase Upsell — best for post-purchase and Plus checkout

Rating: 4.8 (915 reviews) · Built for Shopify: yes · Pricing: $34.99/mo (0–500 orders), $54.99/mo (501–1,000), $99.99/mo (1,001–2,000); the listing sends 2,000+ stores to "see all pricing"; free for development stores only · 30-day free trial

Aftersell one-click post-purchase upsell offer

What it does best: the one-click page between payment and confirmation. Upsell and downsell chains, Smart Funnel AI to pick the offer, targeting by product, cart value, customer tag, language and UTM, and A/B testing with per-offer revenue. On Plus it adds checkout widgets (upsells, reward bars, testimonials).

Placements: checkout (Plus), post-purchase, thank-you page. Nothing on the product page or in the cart. Pricing gates: none by feature; checkout widgets are gated by Shopify's Plus rule, not by Aftersell's plan.

Honest limitation: a $34.99 floor is the highest entry price of any post-purchase tool here, and it buys nothing before checkout. The listing also promotes "Rokt Thanks", which earns you a fee for showing other brands' offers on your confirmation page; it is optional, but decide whether third-party ads belong on your thank-you page before switching it on.

Pick it if: you run Shopify Plus, or post-purchase is the only placement you care about. Setup notes are in Shopify checkout upsell, and Aftersell alternatives covers cheaper routes.

10. Honeycomb Upsell & Cross Sell — best free post-purchase funnel for tiny stores

Rating: 4.6 (145 reviews) · Built for Shopify: no · Pricing: Free (100 funnel views/mo, Honeycomb branding), Silver $54.99/mo (2,000 views), Gold $109.99/mo (5,000), Platinum $169.99/mo (10,000) · 7-day free trial

Honeycomb upsell funnel builder

What it does best: funnels. Product-page, cart-page, in-checkout (Plus), true one-click post-purchase with order merging, and thank-you page offers, with built-in split testing, an autopilot mode and discount stacking, all without touching theme code.

Placements: product page, cart page, checkout (Plus), post-purchase, thank-you page. Pricing gates: the meter is funnel views (offer impressions), not orders, and the free tier shows Honeycomb branding.

Honest limitation: 100 views a month is a few days of traffic for any live store, and the next step is straight to $54.99. No Built for Shopify badge.

Pick it if: you have a handful of orders a week and want to test a post-purchase funnel free before paying anyone. The mechanics are explained in one-click post-purchase upsells.

11. Rebuy Personalization Engine — best enterprise AI

Rating: 4.7 (748 reviews) · Built for Shopify: no · Pricing: "starts as low as" $25/mo and scales with monthly orders; you assemble packages (Cart & Merchandising, Checkout & Post-Purchase, Search & Collections, Flows & A/B Testing); Rebuy Monetize and development stores are free · 14-day free trial

Rebuy Smart Cart with AI recommendations

What it does best: personalisation across the whole session. Smart Cart is an AI-driven slide-out cart, recommendations reach into checkout and accelerated checkout, and the same data feeds post-purchase offers, re-order landing pages and Smart Flows, with integrations for Klaviyo, Attentive, Recharge, Okendo and Route.

Placements: product page, cart drawer, checkout (Plus), post-purchase, thank-you page. Pricing gates: by package; the cart and the post-purchase tools are separate line items.

Honest limitation: the listing publishes only a floor, so you cannot budget from the App Store page, and the no-code/low-code/custom-code spectrum usually means a developer on the project. The May 2026 version of this article quoted a $99 floor; the listing now says $25, so check the current figure before comparing.

Pick it if: you are on Plus with a development team and want one vendor for cart, search and post-purchase. Otherwise read Rebuy alternatives.

12. LimeSpot AI Bundles & Upsells — best for large catalogs

Rating: 4.6 (391 reviews) · Built for Shopify: no · Pricing: Turbo free up to 10 orders/mo (not compatible with Shopify Plus), Turbo $9.99/mo rising with orders (the listing's example: up to 250 orders = $19.99), Max $50/mo rising with store revenue (example: up to $50k revenue = $150/mo) · 15-day free trial

What it does best: AI recommendations on every page type, from the home page to checkout, with bundle and frequently-bought-together offers. Max adds audience segmentation, journey funnels, personalised bundle discounts, smart collections, email and SMS personalisation, A/B/n testing and 70+ integrations.

Placements: product, collection and home pages, cart, checkout extension (Plus), post-purchase, thank-you page. Pricing gates: segmentation, email/SMS personalisation, A/B/n testing and advanced targeting are Max-only.

Honest limitation: Turbo is flagged "not compatible with Shopify Plus", the listing gives worked examples rather than a full ladder, and Max meters on your store's revenue, so the fee grows with the whole business rather than with what the app produced. No Built for Shopify badge.

Pick it if: you have hundreds of SKUs and manual pairings cannot keep up.

13. Bold AI Upsell & Cross‑Sell — best commission-only pricing

Rating: 4.4 (529 reviews) · Built for Shopify: yes · Pricing: Standard free to install plus 3.5% of upsell revenue; Advanced $10/mo plus 2.5% of upsell revenue (adds free-gift offers and in-checkout offers on Plus) · no trial listed

What it does best: AI-selected offers across product pages, cart page and drawer, checkout, post-purchase and email, with chained funnels where each accepted offer triggers the next, plus true upsells, order bumps, Buy X Get Y and subscribe-to-save through Bold Subscriptions.

Placements: product page, cart, checkout (Plus, Advanced plan), post-purchase, thank-you page. Pricing gates: free-gift offers and checkout offers sit on the $10 plan.

Honest limitation: the commission never stops. At $1,000 of monthly upsell revenue you pay $35 on either plan; at $5,000 it is $175 on Standard or $135 on Advanced, more than any fixed plan in this list.

Pick it if: you want no fixed cost and expect cross-sell revenue to stay modest.

14. BOGOS: Free Gift Bundle Upsell — best incentive-led cross-sells

Rating: 5.0 (4,122 reviews) · Built for Shopify: yes · Pricing: Free (30 orders in total), Basic $29.99/mo (Shopify Basic stores only, 300 offer orders included then $0.05 each), Grow $49.99/mo (Grow, Shopify and Professional stores, 600 offer orders then $0.05 each; $69.99 for Advanced and Unlimited plans with 1,000), Plus $109.99/mo (Plus stores only, 2,000 offer orders, adds checkout upsell and the Headless/Hydrogen API) · 7-day free trial, 20% off yearly

BOGOS free gift and BOGO offer widgets

What it does best: cross-sells with a reason attached. Buy one get one, buy X get Y, gift with purchase (auto-add or pop-up), fixed bundles, build-a-box, mix-and-match, volume and tiered discounts, promoted through a progress bar, announcement bar and an offers page. It works from your first order because it needs no purchase history.

Placements: product page and cart widgets, checkout upsell via discount code (Plus plan), thank-you page. No one-click post-purchase page. Pricing gates: the plan you may buy is tied to your Shopify plan; the AI assistant, bundle builder, POS support and offer combining start at Basic; checkout upsell and the headless API are Plus-only.

Honest limitation: 30 free orders in total makes the free tier a trial, and gifts cost margin on orders that would have converted anyway, so set thresholds above your current average order value and read the per-offer report after a week.

Pick it if: your cross-sells are planned promotions rather than automated suggestions. See best Shopify BOGO apps and how to add a free gift with purchase.

Also checked on 2 September 2026, but not in the 14

  • Also Bought CBB — 4.8 (314 reviews), Built for Shopify, one flat $19.99/mo plan with unlimited products, orders and traffic, 14-day trial. A "customers also bought" widget for the product page and cart page only. Worth it if you want one flat price and nothing else.
  • Upsell, Cross sell & Bundles (Aheadworks) — 4.7 (454 reviews), Built for Shopify. Free plan with 2 locations and 50 recommendation clicks a month (branded), then $29.99 (3 locations, 2,500 clicks), $49.99 (8 locations, 5,000 clicks) and $59.99 (8 locations plus custom pages, 10,000 clicks).
  • Glood Product Recommendations — 4.8 (110 reviews), no badge. Free-forever tier for recently viewed, trending and bestseller widgets; Basic $19.99/mo (10,000 widget displays, adds personalised, similar, bought-together and mini-cart recommendations), Pro $69.99 (100,000 displays), Plus $299.99 (500,000 displays, A/B testing, checkout upsell, API).
  • Nosto — 4.8 (51 reviews), no badge on the App Store listing. "Free to install", but the listing states a paid Nosto account is required and billed outside Shopify, so it is an enterprise contract rather than an app plan.
  • Shopify Search & Discovery — 2.7 (465 reviews), free, built by Shopify. Covered in the FAQ; it is the baseline every store should set up before paying for an app.

Best free Shopify cross-sell apps (with the real limits)

"Free plan available" on the App Store means three different things. Some plans are free up to a volume ceiling, some are metered on results, and some only apply to development stores. Here is what each free tier in this list actually allows, read from the listings on 2 September 2026.

  • Selleasy — free to install up to 50 total store orders a month, with every placement (product page, cart, checkout on Plus, post-purchase, thank-you) and 50 AI recommendations. The most complete free tier here.
  • Wiser AI — free for stores with 0–50 monthly orders, same features as the paid tiers, including AI frequently-bought-together, the cart drawer, post-purchase and thank-you offers.
  • Essential Upsell & Cross Sell — free until the app has attributed $100 of extra revenue to itself; product-page and post-purchase offers only, no cart drawer until $19.99/mo.
  • Frequently Bought Together CBB — free for 3 manual bundles with basic styling and no automatic recommendations.
  • Honeycomb — free for 100 funnel views a month with Honeycomb branding; every placement is included.
  • LimeSpot Turbo — free up to 10 orders a month, and not available on Shopify Plus.
  • BOGOS — free for 30 orders in total, then a paid plan.
  • Bold AI Upsell — free to install with no ceiling, but 3.5% of every dollar of upsell revenue is charged.
  • Upsell, Cross sell & Bundles (Aheadworks) — free for 2 locations and 50 recommendation clicks a month, with the app's branding.
  • Shopify Search & Discovery — free with no ceiling: up to 10 hand-picked complementary products per product on the product page, in themes that include the block.

Development-store-only "free plans" (ReConvert, Aftersell, Rebuy, Upcart, Candy Rack) are not free for a live store; the trial is the free period. If you are under 50 orders a month, Selleasy or Wiser AI gives you every placement at no cost. If you only want a product-page block, Search & Discovery plus FBT CBB's three bundles costs nothing. If you want a post-purchase funnel free, Honeycomb's 100 views is the only option and it runs out quickly.

How to choose a cross-sell app by store stage

Pre-launch to 50 orders a month. Set up complementary products in Search & Discovery first (it is free and needs no app), then add Selleasy or Wiser AI on their free tiers. You do not have enough order history for any recommendation engine to beat your own pairings yet, so hand-pick them.

50 to 500 orders a month. Decide on the primary placement. If shoppers add one item and leave, the cart drawer is where the offer belongs, so pick from the drawer-first rows in the placement table. If your problem is low items per order on the product page, Selleasy at $9 or FBT CBB at $19.99 is the cheapest fix. Add a thank-you page tool (ReConvert from $4.99) only after the first placement is converting.

500 to 2,000 orders a month. Watch the ladders. Selleasy is still $19–$29, FBT CBB is $39.99, Aftersell is $54.99–$99.99, and Candy Rack, Wiser AI and Upcart stop publishing prices at 500 or 1,000 orders, so ask before installing. This is also the point where automatic recommendations start to outperform manual pairings, which is why Wiser AI, LimeSpot and Rebuy appear in shortlists at this size.

2,000+ orders or Shopify Plus. Checkout blocks unlock, so Aftersell, ReConvert, Rebuy, Candy Rack and Honeycomb can put an offer on the payment page. Budget for a quote rather than a listed price with Rebuy and the higher Aftersell tiers. If you also need true upsells (bigger size, premium version), best Shopify upsell apps is the companion list.

How to cross-sell on Shopify in 5 steps

  1. Turn on the free baseline. In Shopify admin open the Search & Discovery app, go to Product recommendations, pick a product and add up to 10 complementary products. They need to be active and in stock, and your theme must include the complementary-products block in the product-information section.
  2. Pick one placement. Product page if shoppers buy one item and never see the accessories; cart drawer if they add one item and head to checkout; post-purchase if you sell consumables that are easy to reorder. Start with one, measure, then add the next. Product page upsells and in-cart recommendations walk through the first two.
  3. Pair complements, not substitutes. Shopify's own definition is the useful test: a related product is a similar item the shopper might buy instead, a complementary product is one they buy in addition. A cross-sell is always the second kind. Pull your last few hundred orders, note which SKUs appear together, and build offers from those pairs.
  4. Price the offer so it is an easy yes. Keep the add-on well below the price of the item it attaches to, and only discount it when margin allows. If you use Shopify's native discounts for the incentive, remember the platform caps active automatic discounts at 25 per store.
  5. Measure and prune weekly. Track attach rate (orders that took the offer divided by orders that saw it), AOV before and after, and checkout conversion, then swap out the offers nobody takes. Measuring cart upsell performance lists the exact metrics.

5 cross-selling mistakes that cost sales

  1. Showing too many offers. Six recommendations under the add-to-cart button turn a decision into a catalog. Two or three on the product page, one or two in the cart drawer, and one on the post-purchase page is plenty; Shopify itself caps accepted post-purchase offers at three per checkout.
  2. Cross-selling substitutes. A second pair of running shoes next to the pair in the cart is a related product, not a cross-sell, and it invites the shopper to reconsider rather than add. Socks, insoles and a bag are the cross-sells.
  3. Repeating the same offer at every placement. If the product page, the drawer and the post-purchase page all push the same SKU, the second and third impressions are wasted. Assign different offers to different placements.
  4. Putting the only cross-sell on the post-purchase page. That page is skipped for shoppers paying with Apple Pay, Google Pay, Amazon Pay, Klarna, Affirm, Afterpay or a gift card, so a share of your orders will never see it. Keep at least one pre-checkout placement.
  5. Adding friction to the cart. The cart is already where 70.22% of carts are abandoned on Baymard Institute's average. Pop-ups that block the checkout button, redirects to a bundle page and widgets that shift the layout while loading all make that worse. Prefer one-click adds inside the drawer, and check the Built for Shopify badge or run a before-and-after Lighthouse test before you commit.

Two patterns stand out. Flat or order-based ladders (Selleasy, FBT CBB, Oxify, Aftersell) are the only ones you can budget from the listing at every volume. Result-metered pricing (Essential, ReConvert, Bold, Honeycomb, LimeSpot Max) gets more expensive precisely when the app is working, which is fine at small volumes and worth re-checking every quarter as you grow.

Frequently Asked Questions

What is the difference between an upsell and a cross-sell?

An upsell replaces the item with a better or bigger version of the same thing (a 1 kg bag instead of 500 g). A cross-sell adds a different, complementary item to the same order (filters with the coffee). Upsells raise the price of one line; cross-sells raise the number of lines.

What is the best free cross-sell app for Shopify?

For a store under 50 orders a month, Selleasy or Wiser AI: both are free to install at that volume and cover product page, cart, post-purchase and thank-you placements. For a product-page-only block, Shopify's free Search & Discovery app plus Frequently Bought Together CBB's three free manual bundles costs nothing. Essential is free until it has attributed $100 of revenue, and Honeycomb is free for 100 funnel views a month.

Does Shopify have a built-in cross-sell feature?

Yes. The free Shopify Search & Discovery app lets you choose up to 10 complementary products per product, and compatible themes show them as a block in the product-information section. The items must be active and in stock. It has no cart drawer, checkout, post-purchase or thank-you placement, no discounts and no order-history logic, which is what the paid apps add.

Which cross-sell app is best for the cart drawer?

Oxify Cart Drawer & Upsell (4.9 from 37 reviews, Built for Shopify, from $9.99/mo) puts cross-sells, add-ons, free gifts and a rewards bar inside the drawer and covers the other placements on the same plan. Upcart (4.7, from $29.99/mo) is the pick if a developer wants full control of the drawer markup, and Rebuy's Smart Cart suits Plus stores with a budget for AI personalisation.

Which cross-sell app is best for Shopify Plus checkout?

Aftersell (4.8, from $34.99/mo) for checkout widgets plus one-click post-purchase, ReConvert (from $4.99/mo) if you also want the thank-you page builder, and Rebuy for AI recommendations in checkout and accelerated checkout. App blocks on the information, shipping and payment pages are Plus-only; thank-you, order-status and post-purchase extensions work on Basic Shopify and above.

How many cross-sell products should I show?

Two or three on the product page, one or two in the cart drawer, and one at a time on the post-purchase page, where Shopify caps accepted offers at three per checkout. Search & Discovery allows up to 10 complementary products, but that is a ceiling, not a target. Fewer, better-matched offers get taken more often than a long row of loosely related items.

Do cross-sells hurt conversion rate?

They can when they add friction: a pop-up that hides the checkout button, a redirect to a bundle page, or a widget that shifts the layout as it loads. One-click adds inside the drawer or on the post-purchase page do not interrupt checkout. Test one placement at a time and watch checkout conversion alongside AOV; do upsells hurt conversion rate covers how to run that test.

How do I measure whether cross-selling is working?

Track four numbers: attach rate (orders that took an offer divided by orders that saw one), average order value before and after, cross-sell revenue per session, and checkout conversion rate. Most apps here report the first three in their own analytics; checkout conversion comes from Shopify's analytics. If AOV rises and checkout conversion falls, the offer is costing more than it earns.

If the cart drawer is where you want cross-sells to live, Oxify Cart Drawer & Upsell (4.9, Built for Shopify) covers the drawer, product page, checkout, post-purchase and thank-you page on one plan from $9.99/mo, with every feature on every tier. Details on the cart drawer upsell page, and the 14-day free trial is enough to see the attach rate on your own orders.
