One-Click Upsell on Shopify After Checkout: Setup & Best Practices

Step-by-step overview of Shopify one-click post-purchase upsells for DTC brands — setup, templates, and measurement.

A one-click upsell lets buyers add a product after paying without re-entering card details. On Shopify, this is powered by post-purchase extensions from apps like RefillPost.

Setup checklist

Install the app from the Shopify App Store
Create a funnel: template → product → launch
Enable post-purchase in Shopify checkout settings
Place a test order and confirm the offer appears

Measure what matters

Track acceptance rate, revenue per impression, and incremental AOV. One converting upsell per day often pays for a flat $29/mo app fee on mid-size DTC stores.
