The best Shopify cross-sell app in 2026 is Oxify Cart Drawer & Upsells. It holds a 5.0 rating with the Built for Shopify badge and runs cross-sells in the cart drawer, frequently bought together on the product page, and one-click post-purchase offers, all in one app from $19.99/month with a 14-day free trial.
Every rating, review count, and price below was reviews live from the Shopify App Store in May 2026. Full breakdown follows.
What is a Shopify cross-sell app?
A Shopify cross-sell app suggests related products to shoppers while they buy. The goal is simple: lift your average order value (AOV) without paying for more traffic.
A cross-sell offer can appear in four spots:
- Product page (“Frequently bought together”)
- Cart drawer (“Add to your order”)
- Thank-you page (one-click, after payment)
- Checkout (Shopify Plus only)
Good apps cover three or more of these. Weak apps cover one, so you end up stacking tools to fill the gaps.
Cross-sell vs upsell vs bundle (the 30-second version)
These three get mixed up constantly:
- Cross-sell = a related product (shoes + socks)
- Upsell = a better version of the same product (small to large)
- Frequently bought together (FBT) = a 2-3 product mini-bundle built from real order data
- Bundle = items packaged as one purchase, usually discounted
Most top apps handle two or three. Only a few handle all four.

Notice how few apps carry the Built for Shopify badge. Shopify only awards it to apps that meet strict performance, design, and integration standards. Most “top 15” lists never mention it, and it’s one of the fastest ways to filter quality from noise.
1. Oxify Cart Drawer & Upsells — Best Overall

Why it’s #1: No other app on the Shopify App Store combines cart-drawer cross-sells, FBT bundles, free gifts, BOGO, volume discounts, and one-click post-purchase offers into a single Built for Shopify app at this price. Most stores need three to five separate tools to do what Oxify does in one.

Cons:
- Newer to the App Store, so the review count (30+) is smaller than 5-year-old tools like Bold or Rebuy
Best for: Any Shopify store, new or Plus, that wants one clean tool instead of a stack.

Code Black Belt built one of the first Amazon-style “frequently bought together” widgets for Shopify back in 2017. Its engine has been learning from order data for years, which keeps the suggestions sharp.

A separate Post-purchase + Checkout track starts at $133.99/mo.

Where to place cross-sells for the most AOV
This is the part most lists skip. Where you show a cross-sell matters as much as which app you pick.
Touchpoint 1: Cart drawer (highest intent)
The shopper already said yes and added something. This is your hottest moment. Show: one or two related picks, a free shipping progress bar, a free gift at a spend threshold. Best apps: Oxify, Rebuy.
Touchpoint 2: Product page (still deciding)
Shoppers are weighing it up. Show what others buy together. Show: “Frequently bought together” with 1-click add, product add-ons (gift wrap, warranty). Best apps: Oxify, Frequently Bought Together by CBB.
Touchpoint 3: Thank-you page (lowest friction)
Already paid. One-click adds with no payment re-entry. Pure incremental revenue. Show: a single high-margin add-on, a subscription opt-in if it fits. Best apps: Oxify, ReConvert, AfterSell.
Touchpoint 4: Checkout (Shopify Plus only)
Branded checkout blocks. Hardest to set up, biggest reach on Plus. Best apps: Oxify Cart Drawer & Upsell, Rebuy.
How to choose a cross-sell app (by store stage)
Brand new (under 100 orders/month): Start free. Try Selleasy’s free plan or Oxify’s 14-day trial. Test which converts before committing.
Scaling (100-1,000 orders/month): Install one all-in-one. Oxify at $19.99/mo covers cart drawer, product page, and post-purchase, so you skip stacking three tools.
Shopify Plus (1,000+ orders/month): Pair an all-in-one Oxify or Rebuy for checkout-level offers.
6 things to check before you install
- AI vs manual: Do you want automatic pairings or hand-built control?
- Touchpoint coverage: Product page, cart, checkout, post-purchase, or all four?
- Built for Shopify badge: A fast filter for performance and quality.
- Integration depth: Does it sync your catalog and respect inventory in real time?
- Analytics: Can you see attach rate, AOV lift, and A/B results?
- Pricing model fit: Flat, order-based, session-based, or revenue-share? Make sure it won’t spiral as you grow.
5 cross-selling mistakes that kill conversions
- Too many offers. Cap it at one or two per touchpoint. More just gets ignored.
- Random picks. A yoga mat next to a phone case kills trust. Use AI or clear rules.
- Same offer for everyone. Use rules based on cart value, products in cart, or customer tag.
- No mobile testing. Most Shopify traffic is mobile. Test on a real phone, not a preview.
- Stacking four apps. It slows your store and triggers widget conflicts. One all-in-one wins.
Set up your first cross-sell in 5 steps
- Pick your main touchpoint. Cart drawer is the highest ROI for most stores.
- Install one all-in-one app. Oxify covers cart, product page, and post-purchase out of the box.
- Create your first offer. Use three to five top sellers as cross-sell anchors.
- Set rules. Cart under $50 → low-priced add-on. Cart over $100 → free gift.
- Track weekly. Watch cross-sell revenue and swap out weak performers.
A clean setup takes about 30 minutes. Full optimization takes about 30 days of testing.
Frequently asked questions
What is the best cross-sell app for Shopify in 2026?
Oxify Cart Drawer & Upsells. It holds a 5.0 rating with the Built for Shopify badge and combines cross-sells, frequently bought together, free gifts, BOGO, volume discounts, and one-click post-purchase upsells in one app from $19.99/month with a 14-day free trial.
Which cross-sell app integrates with email marketing?
LimeSpot is the strongest pick if email and SMS recommendation widgets matter, since it extends cross-sells into both channels. ReConvert and Rebuy also sync with Klaviyo, and Oxify works alongside your existing Klaviyo or Omnisend flows.
Are there affordable cross-sell apps for Shopify that actually work?
Yes. ReConvert starts at $4.99/month and Selleasy is free up to 50 orders/month. For a stack that scales, Oxify at $19.99/month replaces three or four separate apps, which usually costs less overall than running them side by side.
Which cross-sell app has the best customization?
Oxify offers deep design control (custom CSS, drag-and-drop, rules) across cart drawer, product page, and post-purchase. Candy Rack and AfterSell offer strong design control on their specific touchpoints.
What’s the difference between cross-selling and upselling?
A cross-sell offers a related product (socks with shoes). An upsell offers a better version of the same product (a larger or premium tier). Cross-sells grow basket count; upsells grow basket size. Strong apps handle both.
Where should I show cross-sell offers on my store?
In four spots, ranked by conversion strength: cart drawer (highest intent), product page, thank-you page, and checkout (Plus only). The cart drawer converts best because the shopper has already added an item.
Do cross-sell apps slow down my store?
Poorly built ones can. Apps with the Built for Shopify badge (like Oxify, Selleasy, and AfterSell) meet Shopify’s strict performance standards, so check for the badge first. Stacking three or four apps will slow your site even if each one is well built.
Is there a free Shopify cross-sell app?
Yes. Selleasy has a free plan up to 50 orders/month across product page, cart, checkout, and post-purchase. Frequently Bought Together by CBB has a free plan for product-page bundles. Oxify runs a 14-day free trial on every plan plus a free plan.
How much does a Shopify cross-sell app cost in 2026?
From free (Selleasy, FBT) up to $749/month (Rebuy’s top tier). Most mid-tier apps land between $20 and $80/month. Oxify starts at $19.99/month, Rebuy at $99/month, and AfterSell at $34.99/month (post-purchase) or $133.99/month (with checkout).
Can I run multiple cross-sell apps at once?
You can, but it’s rarely worth it. Stacking three or four apps slows your store, fights for the same widget space, and adds $60-$150 to your monthly bill. Pick one all-in-one (Oxify) for cart drawer, product page, and post-purchase, then only add a second app for Shopify Plus checkout extensions.
Does Shopify have a built-in cross-sell tool?
Online Store 2.0 themes include basic product recommendation blocks, but they’re limited: no cart drawer offers, no post-purchase, no FBT logic, no free gifts, no spend thresholds. For real AOV lift you need a dedicated app.
Final pick: which one should you install?
- Want one app to handle everything? → Oxify Cart Drawer & Upsells
- Want a free plan to start? → Selleasy
- Want only product-page FBT? → Frequently Bought Together by CBB
- Want thank-you page only? → ReConvert / Upsell.com
- Running Shopify Plus? → Pair Oxify with AfterSell
For the vast majority of Shopify stores, one all-in-one beats stacking five tools. That’s exactly what Oxify Cart Drawer & Upsells is built for, and why it ranks #1 here.
