Raising your average order value is one of the most profitable ways to grow, because every extra euro per order comes in without paying for more advertising to win that customer. That is why upselling and cross-selling are among the first levers we work on when a store wants to improve its profitability without relying solely on more traffic.
Upselling means offering a better or bigger version of the product the customer already wants, and cross-selling means suggesting complementary products. You can apply them on the product page, in the cart, at checkout and after purchase, and each point has its ideal app. Shopify doesn't offer these features out of the box beyond the basics, so you need an app that does it well without slowing the store down or annoying the customer.
In this article we look at the three best upsell and cross-sell apps for Shopify in 2026, with their approximate pricing and the type of store each one suits.
Why use an upsell and cross-sell app?
A good upsell app lets you show the right offer at the right moment without touching code. Post-purchase offers, the ones that appear on the thank-you page right after payment, are among the most profitable, because the customer has already bought and accepting doesn't require them to enter their payment details again. Cross-selling in the cart and on the product page raises order value before payment, and checkout upsells make the most of the final moment of decision.
The key is relevance rather than volume: offers should fit and stay out of the way, because an aggressive upsell annoys people and lowers conversion. Each of these three apps stands out at a different point in the funnel.
1. ReConvert, the best for post-purchase upsells
ReConvert specialises in making the most of the moment after purchase. It lets you build custom thank-you pages with one-click upsells, recommendations and time-limited discounts, just when the customer has paid and is most receptive. It is one of the most widely used apps for this, and its block-based setup is simple, with no need to touch code.
There is a free plan to get started, and paid plans start at around $15.99 a month, scaling with orders. It is the most sensible option if you want quick results with a low investment and your priority is the post-purchase upsell, which usually delivers the best return. For most stores, this is where we would start.
2. Rebuy, the best premium option with AI
Rebuy is the most powerful option for personalising recommendations with data. Its AI engine suggests cross-sell and upsell products across the whole store, product page, cart, checkout and post-purchase, learning from buying behaviour to refine what it offers each customer. It gets the most out of a large catalogue where product combinations matter.
Pricing starts at around $99 a month and scales with your volume, so it is a bigger investment than ReConvert. It makes sense for growing brands or Shopify Plus stores that want genuine personalisation and have enough catalogue and traffic for the AI to work with. If you are looking for the premium option, this is it.
3. AfterSell, the best for checkout
AfterSell stands out for upsells inside checkout and on the thank-you page, an area that has become very powerful on Shopify Plus thanks to checkout extensions. It lets you add offers within the payment process itself and after purchase, with A/B testing to measure what works and a quick setup.
It has a free plan for low volumes, and paid plans start at around $34.99 a month depending on orders. It is a particularly good fit if you are on Shopify Plus and want to make the most of checkout upsells, one of the highest-converting points because the customer has already decided to pay.
Which one should you choose for your store?
To sum up, each one wins in a different area. ReConvert is the default option for most stores, thanks to its results-to-price ratio for post-purchase upsells. Rebuy is the premium choice if you want AI-driven personalisation across the whole funnel. And AfterSell gets the most out of checkout, especially on Shopify Plus.
| App | Approximate price | Strongest at | Best for |
|---|---|---|---|
| ReConvert | Free or from ~$15.99/mo | Post-purchase upsells | Most stores starting with upselling |
| Rebuy | From ~$99/mo | AI personalisation across the funnel | Growing brands and Shopify Plus |
| AfterSell | Free or from ~$34.99/mo | Checkout upsells | Shopify Plus stores focused on checkout |
Whichever you choose, keep one thing in mind: every upsell app adds elements and scripts to your store, so it pays to integrate it carefully so that it raises average order value without slowing the store down or annoying the customer.
Frequently asked questions
What is the best upsell app for Shopify? It depends on where you want to apply the upsell. For most stores, ReConvert, thanks to its results-to-price ratio for post-purchase offers. If you want AI-driven personalisation across the whole funnel, Rebuy. And if your focus is checkout on Shopify Plus, AfterSell. It is better to choose based on your situation than on a general ranking.
What is the difference between upselling and cross-selling? Upselling offers a better or bigger version of the product the customer already wants, for example a larger pack or a higher range. Cross-selling suggests complementary products, such as an accessory for what they are buying. Both techniques raise order value, and most apps support both.
Where should upsells go? Post-purchase upsells on the thank-you page usually deliver the best return because the customer has already paid. Cross-selling in the cart and on the product page raises the order before payment, and checkout upsells make the most of the final moment of decision. Ideally, combine several points without overloading any of them.
Do upsells annoy customers? Only when they are done badly. A relevant, well-placed upsell usually improves the experience, because it shows customers something that genuinely suits them. The mistake is placing aggressive offers everywhere, which annoys people and lowers conversion. Relevance matters more than quantity.
Do I need Shopify Plus to use these apps? Not for all of them. ReConvert and Rebuy work on Shopify's standard plans. Upsells inside checkout, where AfterSell shines, rely on checkout extensions that are more powerful on Shopify Plus, although some of its features also work outside Plus.
How much can upselling raise average order value? It varies a lot depending on the product, the offer and how well the app is integrated, so be wary of fixed figures. The sensible approach is to start with relevant post-purchase upsells, measure the extra value per order and the conversion rate of the offers, and adjust based on your own data.
Raising average order value with upselling and cross-selling is one of the most profitable ways to grow, because it makes the most of the traffic you already pay for instead of requiring more. ReConvert, Rebuy and AfterSell cover different points of the funnel, from post-purchase to checkout. The right choice depends on where your biggest opportunity lies and which Shopify plan you are on.
