Upselling is a type of promotion that encourages shoppers to buy more by adding relevant items to their initial order. A suitable Shopify upsell app will help merchants create and monitor upsell offers with smart, automated, built-in tools.
There are many smart strategies you can use to sell more. You can offer product bundles, set up volume discounts, or add a “gift with purchase” offer. You can even show relevant products on the checkout page or the thank-you page. However, trying to code this yourself is difficult and time-consuming. This is why using a dedicated Shopify upsell app is essential. It handles the hard work for you and automates the process.
But with hundreds of options available, which one is right for you? We have done the research. We tested the most popular upsell app on Shopify to see what truly works. In this guide, we list the 10 best Shopify upsell apps in 2026 to help you boost your sales today.
Finding the right upsell app can be tricky because there are so many options to choose from. To help you decide, we installed and tested these upsell apps to see how they actually work. We focused on:
Because every store is different, one single app might not be the best for everyone. Below, we have categorized the best Shopify upsell apps based on specific features so you can find the perfect match for your business.
This strategy is about encouraging customers to buy more units of the same product (Volume Discount) or a group of related products (Bundle) to save money. It is the fastest way to increase your Average Order Value.
These upsells appear right on the product page while the customer is browsing. They usually look like “Frequently Bought Together” widgets or “You might also like” sections.
Suggest relevant products when customers view their cart drawer.
This method interrupts the shopping journey with a special offer, usually immediately after a customer clicks “Add to Cart.”
A post-purchase upsell happens after the customer has paid. This is widely considered the highest-converting upsell method because the trust is already established.
A funnel is smarter than a standard upsell. It uses logic: If a customer accepts Offer A, show them Offer B (a higher-priced item). If they reject Offer A, show them Offer C (a cheaper downsell).
People love free things. Using a “Free Gift” or “Free Shipping” bar motivates customers to spend just a little bit more to reach a goal (e.g., “Spend $10 more to get a free t-shirt”).
If you have a large catalog of products, you don’t have time to manually pair every item. AI recommendations do the work for you by analyzing sales data & customer behaviour.
BOGOS is a Shopify upsell and promotion platform we built for merchants who want to raise AOV without turning the storefront into an interruptive sales machine. The goal is to make upsells feel like a natural next step in the buying flow.
That means showing the right add-on at the right moment, such as on the product page, immediately after adding to cart, inside checkout, or on the thank-you page. We also keep the design consistent with your theme, so it feels native, not an afterthought. BOGOS also supports AI-powered recommendations, so you are not stuck manually mapping every pairing when your catalog grows.
Upsell capabilities:
Strengths: We built BOGOS to keep upsells clean and brand safe. You get flexible layouts and styling controls, so widgets look native and stay readable on mobile. The rules are built for real promo stacks too, so when you want to layer upsells with bundles, volume discounts, or gift campaigns, you can run them from one system instead of patching together multiple apps during peak traffic.
Selleasy is a straightforward upsell tool built around Frequently Bought Together offers. We see it as a reliable choice for merchants with large catalogs, like fashion or electronics, who want to lift AOV through simple, logical pairings instead of attention-grabbing popups. It works best when your add-ons are obvious, so the offer feels helpful, not forced, right on the product page.
Upsell capabilities:
Strengths and limitations: Selleasy’s biggest strength is how clean it feels. It fits into most themes without distracting shoppers, and it tends to add less friction than pop-up heavy setups. The limitation is customization depth. Design controls can feel basic if you want a very branded look, and it does not lean into reward style mechanics like progress bars or tiered gift journeys.
Essential Upsell & Cross Sell is a practical toolkit for merchants who want to cover the core upsell placements without installing multiple apps. We recommend it for growing stores that need quick wins across the product page, cart, and post-purchase, while keeping setup simple.
Upsell capabilities:
Strengths and limitations: The biggest strength is coverage. You can launch several common upsell mechanics from one dashboard and keep your storefront consistent. The interface is easy to follow, so you can ship offers quickly and measure AOV lift without a long build cycle. The limitation is testing depth. If you want advanced sequencing, heavy experimentation, or multi-step offer logic, a dedicated funnel-focused tool will give you more control.
UpCart is a slide cart builder that upgrades the cart drawer at the moment shoppers decide to buy. It’s a great fit for brands that already convert well but want a stronger “last step,” like encouraging customers to add one more item, reach a spend goal, and check out without going back to browse. On mobile, this counts even more because every extra tap is another chance to lose the sale.
Upsell capabilities:
Strengths and limitations: UpCart feels polished and keeps the checkout flow moving, which can lift AOV without hurting conversion rate. The main limitation is scope: it’s built specifically for the cart drawer, so if you also want product page bundles or post-purchase offers, you’ll likely need another app for that.
Opus is a strong competitor in the cart drawer space, focusing on mobile optimization and speed. We find it a great low-maintenance solution for merchants needing a fast, reliable cart that gently incentivizes spending. It is designed to stay lightweight, which is important for high-traffic stores where any extra load can hurt conversion rate.
Upsell capabilities:
Strengths & Limitations: Opus shines in simplicity and performance, with a smooth mobile experience and an intuitive drag-and-drop editor. The reporting is useful for day-to-day tracking, but it can feel more streamlined than enterprise funnel tools, so it is better for quick cart wins than deep, multi-step funnel analysis.
Monk is a powerful combo app that merges cart upsells with gift-with-purchase logic. We see it as a strong contender for brands that want to create a tiered reward experience, like unlocking a free gift or another perk as cart value increases, inside a smooth, customizable interface.
Upsell capabilities:
Strengths & Limitations: Monk’s standout feature is its flexibility in handling complex gift logic without breaking your store design. It can feel very branded, with widgets that look native rather than tacked on. However, the analytics dashboard can feel dense at first. It also takes time to master trigger combinations, so it fits merchants who are comfortable configuring detailed rules rather than wanting a one-click install.
AfterSell is widely considered the gold standard for post purchase upselling. We recommend it for merchants who do not want to interrupt the initial sale, but still want to capture extra revenue right after the customer has committed to buying. It works by showing relevant offers after checkout, when the purchase decision is already locked in.
Upsell capabilities:
Strengths and limitations: AfterSell’s biggest advantage is its low-friction approach for post purchase upsells. Because the order is already placed before the offer appears, you are not putting the original checkout at risk. The limitation is placement focus. If your main goal is to drive AOV before checkout through product page bundles or a cart drawer builder, you will likely pair AfterSell with a separate pre-purchase upsell app.
Zipify OneClickUpsell (OCU) is a veteran funnel builder for brands that treat their store like a sales system, not just a catalog. We like it for DTC teams who want pre-purchase and post-purchase offers tied together in one funnel and improved through testing.
Upsell capabilities:
Strengths and limitations: The biggest strength is control, where the app lets you shape the upsell journey step by step, so customers are not shown random add-ons. You can test offer price, discount type, and copy, then keep only what lifts revenue per visitor without hurting the refund rate. Reporting also makes it easy to spot which step leaks, like a weak first upsell or a downsell that never gets accepted. The limitation is workload. Setup takes time, and the interface assumes you will test and iterate.
Qikify is best for merchants who want value-driven incentives that lift AOV without rebuilding pages quickly. We like it for stores running clear mechanics such as BOGO, Buy X Get Y, bundles, and free gifts, where the offer should feel consistent from the product page to the cart.
Upsell capabilities:
Strengths and limitations: Qikify covers many core promo types in one app and offers a free plan to test before scaling. The tradeoff is sequencing depth. If you need multi-step accept decline funnels and heavy testing, a dedicated funnel tool gives tighter control.
Glood.ai is an AI-driven product recommendation app for Shopify stores that want smarter merchandising across product pages, cart, and checkout. We like it most for catalogs with enough traffic to learn from real browsing and purchase patterns, so recommendations feel relevant and lift AOV without relying on aggressive popups.
Upsell capabilities:
Strengths and limitations: The big advantage is saved time and better relevance. You set placements once, then review performance to see which widgets lift revenue per visitor. The downside is data dependence. New stores may see more generic suggestions until enough sessions accumulate.
There’s no single best Shopify upsell app for every store, only the best fit for your products, traffic, and growth stage. We recommend focusing on one upsell mechanic first, proving impact, then expanding across cart, checkout, or post-purchase. That approach keeps upsells effective instead of overwhelming.
A Shopify upsell app integrates with your Shopify to offer customers additional items based on their in-cart products or shopping behavior.
These offers can be triggered throughout the customer journey and across your web pages (at checkout, product pages, post-purchase, etc.). The app uses collected data to suggest products that entice your buyers.
The most common types of upsell you can offer your customers include:
– Cross-sells: Recommend complementary products that enhance the initial purchase.
– Product bundles: Offer a set of related items at a discounted price.
– Upgrades: Offer a more advanced, higher-cost version of the product.
– Limited-time offers: Create a sense of urgency with soon-to-expire bonuses or discounts.
Most Shopify upsell apps allow sellers to customize the promotions based on various criteria. These setup conditions often include the trigger product, minimum cart value, other discount requirements, etc.
Also, many apps enable you to personalize the content and appearance of these offers to match the brand guidelines.
