10 Best Shopify Upsell Apps

Driving more traffic is expensive. Getting more from the customers already on your site is not. That's the appeal of upsell apps: one well-placed offer after a customer has already decided to buy can lift your average order value (AOV) without spending an extra dollar on ads.

The numbers are real. One Shopify merchant documented $8,873.16 in additional sales from upsell funnels over a few months, with AOV growing from $176.40 to $203 (roughly 15%) after a 2-4 day setup. Post-purchase upsells, where the offer appears after checkout rather than interrupting the buying flow, tend to get take rates around 6% for a matching product offer.

The challenge is picking the right tool. Some apps focus purely on post-purchase thank-you pages, others on cart drawers or product-page popups, and a few try to cover everything. Below are ten worth considering, with notes on where each one fits.

Here are our top 10 Shopify upsell apps.

1. Frequently Bought Together

Frequently Bought Together shows customers a bundle of related products on the product page, pulled from purchase history across your store. The idea is the same as Amazon's "customers also bought" section, applied directly to your Shopify storefront.

• Developer: Code Black Belt
• Price: Free plan available; unlimited plan at $19.99/month.
• App Type: Upsell/bundling
• Rating: 4.9 (2,400+ reviews)

App Features

• Product recommendations built from your store's actual purchase history.
• Flexible display positions: product pages, cart, or checkout.
• One-click bundle discounts with configurable pricing rules.

Pros

• Quick to set up: The interface is straightforward and the defaults work well for most stores.
• Relevant suggestions: Because recommendations come from real purchase data, they tend to be more useful than manually configured ones.
• Free plan: Workable for smaller stores testing the concept.

Cons

• Free plan limits advanced features: Discount types and customization depth require the paid plan.
• Reporting is basic: No granular tracking of which bundle combinations actually convert.

Who Is This App For?

Stores selling complementary products (accessories with clothing, add-ons with tech, consumables with equipment) where customers often buy two or three things at once. If your catalog is mostly standalone items, the recommendations won't be as sharp.

2. Candy Rack

Candy Rack surfaces upsell and cross-sell offers in a popup or inline widget, at add-to-cart or on the cart page. You define which products get offered with which, and how the widget looks.

• Developer: Digismoothie
• Price: Free plan available; paid plans start at $14.99/month.
• App Type: Upsell/cross-sell
• Rating: 4.9 (200+ reviews)

App Features

• Customizable upsell popups and inline widgets.
• Product-specific offer rules (different upsell for each product).
• Works on both product pages and the cart.

Pros

• Design flexibility: You can match the popup style closely to your brand without touching code.
• Targeted offers: Setting product-level rules means you're not showing the same upsell to everyone.
• Accessible for beginners: No technical background needed to configure offers.

Cons

• Free tier is limited: The most useful targeting and design features need a paid plan.
• Popup timing matters: Showing an offer too early or too often frustrates customers; you'll need to tune the settings.

Who Is This App For?

Stores with a wide catalog (fashion, beauty, electronics) where different products warrant different upsell offers. The per-product rule setup pays off if you have the time to configure it.

3. ReConvert Upsell & Cross Sell

ReConvert Upsell & Cross Sell focuses on the post-purchase window: the thank-you page a customer sees after completing checkout. At that point the customer's card is already charged and there's no risk of losing the original sale, so a discount offer (typically 15-20% off a related item) converts at a higher rate than pre-purchase interruptions.

• Developer: ReConvert
• Price: Free plan with basic functionality; paid plans from $7.99/month.
• App Type: Upsell/post-purchase
• Rating: 4.9 (5,000+ reviews)

App Features

• Post-purchase upsell offers on a customizable thank-you page.
• Offer personalization based on what the customer just bought.
• A/B testing to compare offer types and discounts.

Pros

• No checkout interference: The offer comes after the sale is done, so declining it costs you nothing.
• A/B testing included: You can run proper experiments to find what converts rather than guessing.
• Wide adoption: 5,000+ reviews is a meaningful signal for an app this specialized.

Cons

• Free plan is restricted: Post-purchase upsells with full functionality require upgrading.
• Integration gaps: Some third-party tools (subscriptions, loyalty programs) may not connect cleanly.

Who Is This App For?

Any store that wants post-purchase upsells but hasn't set them up yet. This is the most-reviewed app in this category on the Shopify App Store, which makes it the default starting point for most merchants.

4. Bold Upsell

Bold Upsell lets you create upsell and cross-sell offers that appear in a popup on product pages, the cart, or at checkout. You set the rules: when a customer adds product A, show them product B (or an upgrade version of A) at a specified price or discount.

• Developer: Bold Commerce
• Price: Basic plan at $9.99/month; advanced plan at $29.99/month.
• App Type: Upsell, Cross-sell
• Rating: 4.6 (1,500+ reviews)

App Features

• Trigger-based upsell offers across product pages, cart, and checkout.
• Flexible offer types: percentage discount, fixed price, product swap.
• Built-in integration with Shopify checkout.

Pros

• Multiple upsell types: You can offer a product upgrade, a complementary add-on, or a discount on the same item.
• Straightforward setup: The rule builder is clear enough that most merchants configure it without support.
• Customizable offer display: Good control over what the popup looks like.

Cons

• No free plan: You're paying from day one, which is harder to justify before you've proven upsells work in your store.
• Reporting is thin: Tracking which offers actually drive incremental revenue is limited.

Who Is This App For?

Stores that want pre-purchase upsells across multiple touchpoints and are ready to pay for a reliable, well-supported option. Not the best fit if you're still testing whether upsells work for your catalog.

5. iCart Cart Drawer Cart Upsell

iCart Cart Drawer Cart Upsell turns the cart drawer into the upsell surface. Instead of a popup interrupting browsing, offers appear inside the cart itself: related products, progress bars toward a free shipping threshold, time-limited discounts.

• Developer: Identixweb Limited
• Price: Free plan on first 100 orders; paid plans from $9/month.
• App Type: Upsell/Cross-sell/Cart customization
• Rating: 4.8 (390+ reviews)

App Features

• Customizable cart drawer with upsell and cross-sell widgets built in.
• Progress bars for free shipping thresholds or gift qualification.
• Product bundles and add-on recommendations within the cart.
• Smart targeting: show different offers based on cart value, products, or customer tags.
• Analytics dashboard for tracking offer performance.

Pros

• Everything in the cart: Upsells, progress bars, and bundle offers all appear in one place rather than spread across multiple popups.
• No-code customization: Drag-and-drop builder for widget layout.
• Free shipping bar: The threshold progress bar alone has been shown to lift AOV, independent of product upsells.

Cons

• Configuration takes time: New users need to read the docs to understand targeting conditions and widget stacking.
• Cart-stage only: Offers don't show on product pages unless you set up additional integrations.

Who Is This App For?

Merchants who want upsells without adding popup friction to the browsing experience. If your customers frequently abandon at checkout rather than during browsing, in-cart offers are worth testing.

6. Honeycomb Upsell & Cross Sell

Honeycomb Upsell & Cross Sell builds upsell funnels with conditional logic: if a customer declines the first offer, show a different (typically cheaper) downsell rather than just dropping the interaction. You can set offers for product pages, cart pages, and after checkout.

• Developer: Conversion Bear
• Price: Free plan available; paid plans from $19.99/month.
• App Type: Upsell, Cross-sell
• Rating: 4.9 (500+ reviews)

App Features

• Multi-step upsell funnels with decline/accept branching.
• Offers across product pages, cart, and post-purchase.
• Customizable widget layouts with design controls.

Pros

• Funnel logic: A decline doesn't end the sequence; you can present a second offer at a lower price point.
• Targeting by behavior: Show different funnels depending on what the customer added to cart.
• Clean interface: The dashboard is well-organized for managing multiple funnel paths.

Cons

• Price: At $19.99/month for the base paid plan, it's more expensive than simpler alternatives.
• Reporting gaps: Some merchants find the built-in analytics don't break down performance by funnel step.

Who Is This App For?

Stores that want more than a single offer, specifically a structured sequence where a "no" becomes another opportunity. More setup work than the simpler apps, but the funnel logic can recover revenue that a single-offer approach misses.

7. Also Bought

Also Bought displays a "customers also bought" widget on product pages, drawing on purchase history to suggest related items. It's a focused, single-function tool: no popups, no post-purchase pages, just a product recommendation block.

• Developer: Code Black Belt
• Price: $9.99/month (no free plan, but a free trial is available).
• App Type: Product recommendations/upsell
• Rating: 4.9 (500+ reviews)

App Features

• Purchase-history-based recommendations shown on product pages.
• Theme-compatible widget that adapts to your store's styling.
• Straightforward setup with no complex configuration.

Pros

• Automatic recommendations: Once installed, it pulls real purchase data without manual curation.
• Minimal friction: No popups or interruptions; the widget sits on the page without disrupting browsing.
• Affordable at scale: Flat $9.99/month regardless of order volume.

Cons

• No free plan: Requires a paid commitment, unlike some alternatives.
• Single placement: Works only on product pages, not the cart or post-purchase.
• Limited customization: Less design control than widget-based upsell apps.

Who Is This App For?

Stores that want an Amazon-style "also bought" section without managing a complex app. Works best when your catalog has enough transaction history for the recommendations to be relevant (thin catalogs or new stores won't see good suggestions early on).

8. Ultimate Special Offers

Ultimate Special Offers covers a range of promotion types beyond basic upsells: BOGO deals, bundle pricing, quantity discounts, and limited-time offers. It's closer to a promotions platform than a pure upsell tool.

• Developer: Pixel Union
• Price: Free plan with limited features; paid plans from $19/month.
• App Type: Upsell/promotions
• Rating: 4.6 (600+ reviews)

App Features

• Bundle offers, BOGO deals, and quantity-based discounts.
• Display across product pages, cart, and collections.
• Reporting on which promotions drive the most revenue.

Pros

• Versatile offer types: BOGO and volume discounts address scenarios that pure upsell apps don't cover.
• Decent reporting: More visibility into promotion performance than most apps at this price.
• Fits existing branding: The display is customizable enough to look like a natural part of your store.

Cons

• Free plan is basic: Most of the useful offer types are behind the paid plans.
• Can feel cluttered: Running multiple promotion types at once requires careful planning to avoid confusing customers.

Who Is This App For?

Merchants who run multiple promotion types and want to manage them from one app. If you only need a straightforward product upsell, a simpler option is a better fit.

9. Rebolt - Bundle Products

Rebolt - Bundle Products lets you create fixed or "build your own" product bundles that customers can purchase together at a discount. The core use case is encouraging customers to buy a set of related products rather than a single item.

• Developer: Thimatic
• Price: From $9.99/month.
• App Type: Bundling/upsell
• Rating: 4.8 (800+ reviews)

App Features

• Fixed bundles and customer-configurable bundle options.
• Automatic discount application when bundle conditions are met.
• Customizable bundle display designs.

Pros

• Fast setup: Bundles can be live within minutes; no technical skills needed.
• Works for volume discounts: Bundle pricing (1 unit -10%, 2 units -20%, 3 units -30%) has been shown to lift AOV in stores doing multi-unit sales.
• Flexible discount types: Percentage, fixed amount, or free product when threshold is met.

Cons

• Bundles only: There are no popup upsells or post-purchase offers; this is strictly a bundling tool.
• Paid from the start: No meaningful free plan for testing.

Who Is This App For?

Stores where customers naturally buy in multiples or where bundling complementary products makes sense: skincare sets, food/beverage packs, accessory kits. Less useful for stores selling high-ticket, single-purchase items.

10. Bundles & Upsell | PickyStory

Bundles & Upsell | PickyStory covers both product bundles and upsell kits, letting you combine related products into sets that customers can purchase together. It handles both pre-configured bundles and "build your own kit" flows.

• Developer: PickyStory
• Price: Free plan available; paid plans from $14.99/month.
• App Type: Upsell/bundling
• Rating: 4.8 (800+ reviews)

App Features

• Pre-built bundles and configurable kit-building flows.
• Integrated upsell offers alongside bundle creation.
• Customizable bundle display to match store branding.

Pros

• Covers bundles and upsells together: One app for merchants who want both, rather than running separate tools.
• Customizable kits: Customers can choose components within a kit, which can increase perceived value.
• Free plan available: You can test it before committing to a paid tier.

Cons

• Pricing: Pricier than dedicated bundle-only apps for what you get.
• Focused on bundling: If you primarily need standalone product upsells (not kits), simpler apps are a better fit.

Who Is This App For?

Stores that want both bundles and basic upsells without installing multiple apps, and who sell products that customers naturally configure into sets (e.g. gift boxes, component-based products, accessories paired with a main item).
