Checkout Upsell Widget
Show customers their saved wishlist items at checkout and let them add more to their order before they pay. Good uptake, and no negative impact on checkout completion rates.
How to enable
The checkout upsell widget is added via the Shopify Checkout Customiser — not the theme editor.
- Go to Shopify Admin > Settings > Checkout
- Click Customise on your checkout
- In the left panel, go to Apps
- Find and enable Wishlist Checkout Upsell
- Drag it to your preferred position — we recommend placing it below the cart summary
- Save
What customers see
Logged-in customers will see a section showing items from their wishlist that aren't already in their cart. They can add any item directly from the checkout without leaving the page.
Tips
- Placement below the cart summary performs well — it's visible without distracting from the order summary
- You can move it higher in the checkout if you want more prominence
- Works with all Shopify checkout layouts that support checkout extensibility
