10 Best Shopify Upsell and Cross-Sell Apps for 2026 (Free & Paid)

10 Best Shopify Upsell and Cross-Sell Apps

The cheapest sale you will ever make is the second item in a cart that is already open.

I’m Anurag Pandey, founder of ControlF5. After several years of building Shopify stores, I have seen that growing Shopify stores earn more from shoppers who are already buying. That is exactly what Shopify upsell apps and cross-sell apps do. For the strategy behind it, see our guide on Shopify upsell techniques.

I checked 10 Shopify apps on the Shopify App Store in September 2026 and ranked them by rating to help you pick the best upsell app for Shopify.

This list covers upsells and cross-sells only. For bundles, see our Shopify bundle apps roundup.

Market Insights: Where Shopify Upselling Stands in 2026

Insight What it means for your Shopify store
Shopify merchants generated a record $14.6 billion in global BFCM 2025 sales, up 27% from 2024 (Shopify) More ready-to-buy shoppers means more chances to add a second item. Set up upsells before peak season.

What Is a Shopify Upsell App?

A Shopify upsell app shows shoppers a relevant extra offer while they buy, so each order ends up a little bigger.

Think of a good Shopify store assistant. You pick up a camera, and they mention the memory card you will need tonight. That is the whole idea, just automated.

These Shopify apps do two jobs:

  • Upselling: nudging a shopper toward a better or bigger version, like the 1 kg pack instead of 500 g.
  • Cross-selling: suggesting something that pairs well, like a case with a phone.

Native Shopify can show basic related products. A dedicated Shopify app adds control over where offers appear, which products get suggested, what discount applies, and how each offer performs.

That control matters most when your orders are coming in smaller than they should, and I have broken down why average order value stays low on a Shopify store and how to fix it in a separate guide.

Types of Shopify Upsells and Cross-Sells

Every Shopify upsell lives at one of five moments in the buying journey. Decide where your offer should appear, then pick a Shopify app that is strong there.

Upsell type Where it appears What works best Shopify plan needed
Product page upsells and cross-sells Next to the Add to Cart button Low-cost add-ons, frequently bought together, quantity breaks Any plan
Cart drawer upsells Inside the slide-out cart Free shipping bar, gift wrap toggle, paired items Any plan
Checkout upsells Order summary during checkout A Shopify checkout upsell for small, relevant extras Shopify Plus for information, shipping and payment steps
One-click post-purchase upsells After payment, before the thank-you page A one-click upsell Shopify offer with no card re-entry Any plan, through apps
Thank-you page upsells Thank-you and order status pages Discounted reorder items and cross-sells Basic plan or higher

How to Choose the Best Upsell and Cross-Sell App for Shopify

The best upsell and cross-sell app for Shopify is the one that fits your plan, your order volume and the moment your shoppers hesitate. Run through this checklist before you install anything.

  • Upsell placement: Decide where the offer should appear first: product page, cart drawer, checkout, post-purchase, or thank-you page. Pick a Shopify app that is strong in that spot.
  • Shopify Store speed: Every widget adds code. Test your pages before and after install, and read our guide on upsell apps and store speed.
  • Shopify Plus requirement: In-checkout offers on the information, shipping and payment steps need Plus. On Basic, Shopify or Advanced, focus on product page, cart, post-purchase and thank-you offers.
  • Analytics: You should see views, clicks, conversions and revenue per offer. A/B testing is a bonus worth paying for once traffic grows.
  • Pricing model: Check whether the Shopify app charges by total store orders, orders it touches or revenue it creates. Model the cost at your current and next-year volume.
  • Recommendation quality: Manual rules give control, AI saves time. If you want deeper product matching, see our list of Shopify product recommendation apps.
  • Support: Look for live chat and setup help. Most top Shopify apps on this list offer both.

Shopify Upsell and Cross-Sell Best Practices

A good Shopify app with a bad offer still fails. These rules keep every Shopify upsell helpful instead of pushy.

  1. Keep offers relevant. Suggest items that genuinely go with what is in the cart. A charger with a phone works. A random bestseller does not.
  2. Price the add-on right. Keep the suggested item under 20 to 30 percent of the main product’s price, so saying yes feels easy.
  3. Show one strong offer at a time. Three popups in a row train shoppers to click “no”.
  4. Test the placement. The same offer can win in the cart and lose on the product page. Run a split test before you decide.
  5. Watch your speed. A slow page costs more sales than any upsell earns back. Check your scores after every new app.
  6. Plan seasonal offers early. Sale periods bring the most ready-to-buy traffic. Our playbook on Black Friday upsell offers covers what to set up in advance.

For more tactics, see our full guide to Shopify upsell techniques.

Which Shopify Upsell and Cross-Sell App Should You Choose?

Start with the moment your shoppers hesitate, then pick the Shopify app built for it.

  • Starting with zero budget: Selleasy, the best Shopify upsell app for covering every placement for free.
  • Cart is your weak spot: Kaching CartDrawer or AOV.ai.
  • Want post-purchase revenue cheaply: Kaching Post Purchase Upsell.
  • Thank-you page feels empty: ReConvert.
  • High volume and ready to test everything: Zipify OCU.
  • Personalization across the store: Wiser AI.

Whichever Shopify upsell app you choose, install one, measure it for a few weeks, and only then add another. Stacking apps too fast is the quickest way to slow a store down.

At ControlF5, we have shipped 500+ Shopify stores and set up, customize and speed-test upsell flows every week. If you want a second pair of eyes on yours, talk to our team.

Shopify Upsell and Cross-Sell App FAQs

Question: What is the best upsell app for Shopify?

Answer: It depends on where you want offers to appear. Selleasy is the strongest all-rounder with a free plan. Kaching CartDrawer and AOV.ai lead for cart upsells, and ReConvert leads for thank-you pages.

Question: Is there a free Shopify upsell app?

Answer: Yes. Selleasy is free up to 50 orders a month, Essential Upsell has a free plan up to $100 in extra revenue, AOV.ai is free up to 30 app orders a month, and Fly offers one free upsell offer.

Question: Do upsell apps slow down my Shopify store?

Answer: They can, because each widget loads extra code. Apps with the Built for Shopify badge meet Shopify’s performance standards, but you should still test page speed before and after installing.

Question: Can I add upsells to Shopify checkout?

Answer: Yes, with limits. A Shopify checkout upsell on the information, shipping or payment steps needs Shopify Plus. Thank-you and order status page offers work on the Basic plan or higher.

Question: What’s the difference between upselling and cross-selling?

Answer: Upselling offers a better or bigger version of the same item. Cross-selling suggests a related item, which is what a Shopify cross-sell app like Essential or Wiser focuses on.

Question: Do upsell apps work with Shopify Plus?

Answer: Yes. Every Shopify app on this list works on Plus, and Plus stores get the extra option of placing offers inside the checkout steps themselves.
