11 Shopify Upsell and Cross-Sell Apps 2026

Kaching Bundles is the top-rated bundle and quantity-break app, and a different route to a bigger order than a classic upsell popup. Rather than offer a single add-on, it builds buy-more-save tiers and product bundles right on the product page, so shoppers choose to spend more up front. It is the most detected bundle app in our data, with a top rating across thousands of reviews. Our Kaching Bundles review covers setup, and the adoption data shows where it sits among Shopify stores.

Because the discount sits on the product page rather than in a popup, shoppers see the saving while they are still deciding, which tends to feel less pushy than an interruptive prompt. It fits stores with clear complements or multipacks, where a two-for or a tiered break gives a real reason to add one more. The pairing rules and analytics also let you test which bundle actually moves, so you keep what earns and drop what does not.

Highlights:

• Quantity breaks and volume discounts
• Product and mix-and-match bundles
• Discounts apply automatically at checkout
• A/B testing and revenue analytics

ReConvert focuses on the thank you page, the moment right after a customer buys. It shows one click post purchase upsells, order tracking, and surveys, so you add revenue without touching the checkout. For stores that want the easiest upsell to add first, the post purchase slot is low risk and converts well.

Setup runs through a drag and drop editor, so you can rebuild the confirmation page without touching theme code, and the offers read the order that just completed to decide what to show. Because the shopper has already paid, accepting an add on takes a single tap with no second checkout, which is why the post purchase slot converts better than most in cart prompts. For a store adding its first upsell, it is a low risk place to start.

Highlights:

• One click post-purchase offers
• Thank you page funnels
• Order tracking and surveys
• Drag and drop editor

ReConvert is now listed as Upsell.com; see its full usage data across our dataset.

Cross Sell Pro adds related product recommendations to product, cart, and checkout pages, with control over which items pair with which. It is a focused cross-sell tool rather than a full suite, which keeps it quick to configure for stores that just want relevant add ons.

You decide which products pair with which, so recommendations stay relevant instead of pulling in whatever is popular, and the same offers can run on the product page, in the cart, and at checkout. That focus keeps it quick to set up and easy to keep tidy, which suits a store that wants dependable cross sells without learning a full recommendations platform. It carries a high user rating for doing that one job well.

Highlights:

• Recommendations on product, cart, and checkout
• Manual and automatic pairing
• Clean, quick setup
• High user rating

Rebuy is a personalization engine that powers upsell and cross-sell offers from your store’s own purchase data. It places smart product suggestions in the cart, on product pages, at checkout, and after purchase, with a rules engine that controls exactly what shows where. Our Rebuy review walks through the setup, and the Rebuy adoption data shows where it sits among Shopify stores we track. For a store with enough order history to train recommendations, it is one of the stronger picks here.

The rules engine is the part that sets it apart: you control exactly which products surface in each slot, so suggestions reflect real merchandising rather than a generic feed. That depth needs order history to work from, which is why it fits established stores more than brand new ones. Built in testing then shows which recommendations lift order value, so the engine keeps improving as it runs.

Highlights:

• Recommendations trained on your purchase data
• Cart, product page, checkout, and post-purchase widgets
• Rules engine for merchandising control
• Built-in A/B testing

Upsell Now triggers upsell and cross-sell popups at the cart and checkout stages, prompting an add on before the shopper commits. Popups are more visible than inline blocks, so this suits stores that want the offer to be hard to miss.

Because the prompt appears as the shopper moves toward checkout, it catches the offer at the point of decision, and a single tap adds the item without leaving the cart. The free plan makes it easy to trial the format before committing, so a smaller store can see whether visible popups lift its order value. It suits catalogs where one clear add on works better than a wall of suggestions.

Highlights:

• Upsell and cross-sell popups
• Cart and checkout triggers
• One click add to cart
• Free plan available

PickyStory is built around bundles and product kits: buy the look, build a box, or grab a discounted set. Bundling is one of the most natural cross-sells, since it pairs items that genuinely go together. For catalogs where products complement each other, it lifts average order value cleanly.

Beyond simple pairs, it can group a full outfit or a starter set into one add to cart action, turning several related products into a single decision for the shopper. Volume and combo discounts give a reason to take the whole set rather than one item, and the bundles can appear across the storefront rather than on a single page. For catalogs built around collections or kits, it is a natural fit.

Highlights:

• Product bundles and kits
• Buy the look and build a box
• Volume and combo discounts
• Works across the storefront

Cross Sell Ace by Zooomy places upsell and cross-sell offers across the funnel with a strong user rating and a generous free tier. For a smaller store that wants a capable cross-sell tool without an early monthly cost, it is an easy one to trial.

Offers can run on the product page, in the cart, and after purchase, so one app covers the main moments a shopper might add more. The free tier is generous enough to prove the idea before any monthly cost, which is the main reason a newer store would start here. Its rating suggests merchants get reliable results without a heavy setup.

Highlights:

• Upsell and cross-sell placements
• Free tier to start
• Top user rating
• Straightforward configuration

This BeeApp tool adds a related products section to your product pages, surfacing items shoppers are likely to add. It is a lightweight way to cross-sell on the product page itself, where a shopper is already deciding what to buy.

Recommendations can be set automatically or chosen by hand, so you can trust the algorithm on a large catalog or curate exact pairings on a smaller one. Because it targets the product page, it reaches the shopper while they are still weighing the main item, a natural spot to suggest a companion. It stays light on load, so it adds the section without slowing the page.

Highlights:

• Related products on product pages
• Automatic and manual selection
• Lightweight and fast
• Top user rating

Revy’s Unlimited Smart UpSell runs in cart and post purchase offers with no cap on the number of offers you create. It leans on smart triggers to show the right add on at the right step, which suits stores that want to test many offers without a per offer charge.

The uncapped offer count is the point: you can build a separate offer for each product or collection without watching a limit or paying per offer, which makes broad testing affordable. Smart triggers then decide which add on fits the current cart, so the shopper sees something relevant rather than a fixed pitch. That suits a store with a wide range that wants to tailor offers product by product.

Highlights:

• Unlimited upsell and cross-sell offers
• In cart and post-purchase placements
• Smart offer triggers
• Simple setup

Discounted Upsells pairs an offer with an incentive: add this item and take a discount. Tying the upsell to a small saving can tip a hesitant shopper, which makes it a good fit for stores whose add ons are price sensitive.

Tying the offer to a small saving gives a hesitant shopper a concrete reason to say yes, and the discount can apply to a single add on or a quantity deal. Offers run in the cart and on the product page, so the incentive shows up where the shopper is already deciding. For catalogs where price nudges buying, the built in discount does more work than a plain suggestion.

Highlights:

• Upsells with a built-in discount
• In cart and product page offers
• Quantity and combo deals
• Simple to configure

This upsell and cross-sell app covers the main placements, cart, product page, and post purchase, in one tool. For a store that wants a single app to handle both jobs rather than stacking several, it keeps the setup tidy.

Running both jobs from one app keeps setup simple and avoids the conflicts that can happen when two separate tools fire offers on the same page. Custom rules decide what shows where, and the reporting tells you which offers actually earn, so you can prune the rest. For a store that wants one tidy tool rather than a stack, it covers the essentials in a single place.

Highlights:

• Upsell and cross-sell in one app
• Cart, product, and post-purchase offers
• Custom offer rules
• Reporting on offer performance
