The best upsell apps for BigCommerce (2026)

Looking for an upsell app on the BigCommerce marketplace? The honest news: it's a small category — about a dozen apps, several of them dormant — so choosing is less about feature checklists and more about which approach fits your store. Here's the current landscape, as of June 2026. (Disclosure: OrderEdit.io is our product; we've kept this factual and you can verify every claim on the marketplace.)

1. OrderEdit.io — Order Editing & Upsell

Best for: post-purchase offers without checkout friction. Instead of a pop-up that interrupts buying, offers appear on the order confirmation page and inside the customer's self-service edit window — after the sale is safely captured. Add-ons join the existing order (no second checkout, no second shipping), and a free-shipping threshold bar nudges the order value up. From $39/mo, 21-day free trial. The upsell engine rides on the order-editing layer, so you also kill your "change my order" tickets with the same app.

2. Easy Upsell

Best for: pre-purchase pop-up offers — with a caveat. The longest-standing dedicated upsell app (launched 2019, 46 marketplace reviews, 4.6★). Trigger-based pop-ups before and after checkout, A/B testing, $19.99–$99.99/mo priced by impressions. The caveat: its most recent public reviews (2025) report unresponsive support and an unmaintained app — check current reviews before committing.

3. Native Upsell (Peasisoft)

Best for: simple targeted pop-ups on a budget. Part of Peasisoft's three-app suite (Native Upsell, Native Recommender, Native Cart Drawer) with solid review scores. Pop-up offers triggered by cart contents.

4. Unlimited Upsell — Buy X Get Y (Spur-i-t)

Best for: free. Now fully free, monetized by ads shown on your thank-you page — which is the trade-off to understand: your post-purchase real estate carries someone else's ads.

5. BigClick Upsell

Best for: post-checkout offer sequences. A smaller player focused on thank-you-page offer funnels with drag-and-drop templates.

How to choose

Ask one question: do you want to sell before the order (pop-ups, higher friction, risks the original conversion) or after it (confirmation page, zero risk to the sale)? Pre-purchase: look at Easy Upsell or Peasisoft. Post-purchase: that's OrderEdit.io's home turf — and you get self-service order editing in the same subscription.
