Free tool — 15 upsell apps detected

Upsell & Cross-sell App Checker

Detect which upsell and cross-sell apps any Shopify or ecommerce store uses. Identify post-purchase upsells, frequently bought together widgets, cart addons, and bundle builders.

Why upsells matter

Average order value (AOV) is one of the three levers of ecommerce growth (alongside traffic and conversion rate). Upsell and cross-sell apps directly move that lever — post-purchase offers typically convert at 5–15% with zero friction because the customer has already committed to buying.

Post-purchase vs in-cart upsells

Post-purchase upsells (ReConvert, AfterSell) fire on the order confirmation page — the payment is already captured, so a one-click add doesn't interrupt checkout. In-cart upsells (Candy Rack, UpCart) appear before checkout and work best for complementary accessories or service add-ons.

What makes an upsell convert

  • Relevance — recommend products related to what was just purchased
  • Urgency — "Add to your order in one click" framing
  • Discount — even 10% off a complementary item drives acceptance
  • Single offer — multiple offers reduce conversion
  • Mobile-optimized layout — 60%+ of upsell views are on mobile
