Essential Upsell & Cross Sell is our top pick for 2026. It holds a 5.0 rating across 2,171 reviews, carries the Built for Shopify badge, and has a free entry tier. It covers frequently bought together, post-purchase offers, cart-drawer upsells, and BOGO bundles. Just know the free plan only covers your first $100 of upsell-generated revenue, so most stores will graduate to a paid tier fast.

Best Shopify upsell & cross-sell apps in 2026, ranked
We tested 3 Shopify upsell & cross-sell apps across pricing, features, and App Store ratings. Top picks below — each card shows what it does, rating, pricing, and the one-click install link.
The upsell category on Shopify is crowded, and most of these apps promise the same five things: frequently bought together blocks, cart add-ons, post-purchase offers, and bundles. The real decision isn't whether an app can show a recommendation. It's where those offers appear and how the pricing scales as you grow. Both of the metered apps here get more expensive as you do more volume, they just measure it differently, and that detail matters more to your margin than any single feature checkbox.
All three picks carry the Built for Shopify badge, so theme integration and performance aren't a concern with any of them. What changes is the billing model and where offers show up. Selleasy bills by your monthly order count. Essential Upsell bills by how much extra revenue its upsells generate. Koala uses flat monthly tiers with no permanent free plan, only a 14-day trial. Pick based on your volume and the offer surfaces you actually want, not the feature list.

Essential Upsell & Cross Sell
Best for stores that want the main upsell surfaces and prefer billing tied to the revenue the app actually generates. It runs frequently bought together, post-purchase offers, cart-drawer upsells, one-click upsells, and BOGO bundles. The free tier lets you try it, but it only covers your first $100 of upsell revenue, so you'll move to a paid plan quickly. Pricing climbs with generated revenue up to $39.99/mo for unlimited, and it doesn't advertise behavior- or location-based targeting.
What it does
- Frequently bought together, related products, and recommendations on product pages
- Post-purchase upsell and cross-sell with add-ons and bought-together bundles
- Automatic discount promotions you can attach to upsell and 'also bought' products
- Product page one-click upsell, cross-sell, and BOGO bundles
- Cart upsell with cross-sell and add-ons inside the cart drawer
Upsell & Cross Sell — Selleasy
Best when you want offers at checkout and on the thank-you page, not just the cart. It shows Amazon-style frequently bought together bundles and lets you display cross-sells as a list, grid, carousel, or popup. Pricing is order-based, so it's cheap at low volume and climbs as you grow. The caveat: once you clear 1,000 orders a month you're at the top $29/mo tier, and high-volume stores should price that against rivals.
What it does
- Amazon-style frequently bought together upsell bundles
- Product-page cross-sell add-ons as list, grid, carousel, or popup
- In-cart upsell funnel via popup or directly in the cart drawer and theme
- Checkout upsells plus one-click post-purchase page upsell
- Thank-you-page and order-status-page cross-sells after the sale
Koala Free Gift BOGO Upsell
Best if your strategy centers on free gifts and targeted pop-ups. Koala can auto-add a gift when specific items hit the cart, and it's the only pick here that triggers offers based on a customer's past behavior or location. The caveat: there's no permanent free plan, just a 14-day trial, and its 361-review sample is far smaller than the others, so the 4.9 rating rests on less data.
What it does
- Upsell pop-ups, product add-ons, and free gift offers from templates
- Automatically adds gifts to the cart when specific items are added
- Custom upsell offers applied to the items being added to the cart
- Rules that offer upsells based on a customer's previous behavior
- Rules that offer upsells based on a customer's location
Which Shopify upsell & cross-sell app should you choose?
Pick the one that maps to your current bottleneck. Install on a duplicate theme first, test for a week, then commit.
- Check how each app meters you before anything else. Selleasy charges by monthly order count (free up to 50 orders, then $9/$19/$29 tiers). Essential Upsell charges by the additional revenue its upsells generate (free up to $100, then $9.99/$19.99/$39.99). Koala uses flat monthly tiers regardless of volume. None of these is truly a fixed flat fee until you reach Essential's top plan or Koala's chosen tier.
- Confirm there's a free entry tier if budget matters. Essential Upsell is free up to $100 of generated revenue, and Selleasy is free up to 50 orders a month. Both are thin starter tiers you'll likely outgrow. Koala has no permanent free plan, just a 14-day trial, then starts at $9.99/mo.
- Match the offer surfaces to your store. If you specifically want checkout and thank-you-page cross-sells, Selleasy lists those clearly. Essential Upsell covers product page, cart drawer, post-purchase, and one-click upsells. Koala leans into pop-ups, free gifts, and rules-based targeting.
- Decide if you need rules-based targeting. Koala is the only one here that lists offers triggered by a customer's previous behavior and location. The other two don't advertise that.
- Look at how the offers display. Selleasy lets you show cross-sells as a list, grid, carousel, or popup. If presentation flexibility matters, that's worth weighing.
- Weigh the review sample size. Essential Upsell (2,171 reviews) and Selleasy (2,407 reviews) have deep track records. Koala's 361 reviews is a smaller sample, so treat its 4.9 rating as less settled.

Frequently asked questions
Which of these apps is actually free, and which just have a trial?
Two have permanent free entry tiers, but both are thin. Essential Upsell is free until its upsells generate $100 in revenue, and Selleasy is free up to 50 orders a month. Koala has no permanent free tier, only a 14-day trial, after which the cheapest plan is Basic at $9.99/mo.
How does the pricing actually scale on each app?
Selleasy bills by monthly order count: free up to 50, $9/mo up to 500, $19/mo up to 1,000, and $29/mo past 1,000. Essential Upsell bills by additional revenue its upsells generate: free up to $100, $9.99 up to $500, $19.99 up to $1,000, and $39.99/mo for unlimited. Koala charges a flat monthly tier you choose, from $9.99 to $99.99/mo, no matter your volume.
I want upsells at checkout and on the thank-you page. Which app does that?
Selleasy is the one that clearly lists checkout upsells, one-click post-purchase upsell, and cross-sells on the thank-you and order-status pages. Essential Upsell covers post-purchase, cart, and one-click upsells. Koala focuses on pop-ups and free gifts rather than checkout-stage offers.
Can I target upsells based on customer behavior or location?
Only Koala lists that. Its listing spells out rules to offer upsells based on a customer's previous behavior and based on their location. Essential Upsell and Selleasy don't advertise behavior or location targeting, so Koala is the pick if rules-based targeting is central to your plan.
Will running two of these at once cause conflicts?
All three are Built for Shopify, so each integrates cleanly on its own. Running two upsell apps that both inject offers into the cart drawer or product page can create duplicate or competing offers, though. Pick one and configure its surfaces fully rather than stacking apps for the same job.
Is 4.9 across 361 reviews trustworthy for Koala?
Treat it as promising but less settled. Koala's 4.9 comes from 361 reviews, a much smaller sample than Essential Upsell (5.0 across 2,171) or Selleasy (4.9 across 2,407). A smaller sample can shift more with each new review, so the two larger-sample apps give you a steadier read.
