Upselling and cross-selling are the highest-ROI growth tactics available to Shopify merchants — you are selling to someone who has already decided to buy. The right upsell app can increase your average order value by 15 to 30 percent without increasing your ad spend. But different apps specialise in different placements (product page, cart, checkout, post-purchase), and the best choice depends on where in the funnel you want to focus. Here is a comparison of the best Shopify upsell apps in 2026.
ReConvert: Best for Post-Purchase Thank-You Page Upsells
ReConvert specialises in turning the post-purchase thank-you page into a revenue-generating asset. After a customer completes payment, ReConvert shows targeted offers — a one-click upsell, a bundle offer, or a discount for a second purchase — on the order confirmation page. Because the customer has already committed to buying, acceptance rates on post-purchase offers are significantly higher than on pre-checkout pages (typically 8 to 15 percent). ReConvert is free for stores with up to 49 orders per month, then starts at $4.99/month. Best for stores wanting to maximise post-purchase revenue without disrupting the checkout flow.
Frequently Bought Together: Best for Product Page Bundles
Frequently Bought Together adds an Amazon-style “customers also bought” bundle widget to your product pages. Customers can add all items in the bundle with one click. The app uses purchase history data from your store to recommend genuinely relevant pairings, which drives higher acceptance than manual recommendations. Free plan available; paid plan at $9.99/month. Best for stores with a catalogue that has natural product pairings — tech accessories, skincare routines, cooking kits, and similar complementary products.
Bold Upsell: Best for Full-Funnel Coverage
Bold Upsell covers every placement: product page, cart, checkout (requires Shopify Plus or Checkout Extensibility), and post-purchase. You can set rules for when offers appear (if customer adds Product A, show offer for Product B). Bold is more complex to set up than ReConvert but gives you greater control over the entire upsell funnel. Pricing starts at $9.99/month. Best for established stores wanting a single app to manage upsells across all touchpoints. For strategic advice on upsell architecture for your store, OneOnic’s CRO service covers offer design and A/B testing.

Frequently Asked Questions
Will upsell pop-ups on the product page hurt my conversion rate?
They can if they are poorly timed or irrelevant. An upsell offer that appears before the customer has decided to buy the main product can distract and reduce add-to-cart rate. Post-purchase upsells (ReConvert, AfterSell) are the safest — the sale is already complete, so showing an offer cannot reduce your main conversion rate. If you add product-page upsells, monitor your add-to-cart rate closely before and after to measure any negative impact.
What is a realistic AOV increase from upsell apps?
Well-implemented upsell strategies typically deliver a 10 to 25 percent AOV lift. Post-purchase upsells see 8 to 15 percent acceptance rates; cart-page cross-sells see 4 to 8 percent. The lift depends heavily on offer relevance (the upsell must make sense given what the customer is buying) and price anchoring (post-purchase upsells priced at 20 to 40 percent of the original order value convert best). Do not expect double-digit AOV lift from just installing an app — the offer strategy is what drives results.
