Checkout Extensions vs AfterSell
AfterSell focuses on post-purchase upsells. Checkout Extensions covers the full checkout journey — from the first page through to the thank-you page.
Feature comparison
Why merchants choose Checkout Extensions
Full checkout coverage, not just post-purchase
Checkout Extensions adds blocks at every stage — checkout pages, thank-you, and order status. AfterSell is primarily a post-purchase funnel tool.
Checkout-native upsells
Show upsells and cross-sells inside the checkout flow itself (before payment), not just after the order is placed.
No funnel builder complexity
Simple block-based editor. No funnel sequences, flow logic, or pop-up configurations to manage.
All-in-one
Replace AfterSell plus several other apps — trust badges, countdown timers, free shipping bars, custom fields — with a single subscription.
If post-purchase upsell funnels are your primary focus and you want advanced funnel sequencing and A/B testing for the thank-you page.
If you want to increase AOV at checkout (before the order is placed) as well as post-purchase, plus branding and trust blocks — in one app.
Common questions
Does Checkout Extensions do post-purchase upsells like AfterSell?
Yes. The Post-Purchase Upsell block shows a one-click offer on the thank-you page immediately after checkout. Payment is already authorised, so customers accept in seconds.
Can Checkout Extensions replace AfterSell entirely?
For most merchants, yes. If your primary use case is thank-you page upsells, Checkout Extensions covers this. If you rely on AfterSell's multi-step funnel builder, the two products differ there.
Is switching from AfterSell difficult?
No. Install Checkout Extensions, set up your Post-Purchase Upsell block, and remove AfterSell. Both apps work through Shopify's native extensibility API.
What about analytics — does Checkout Extensions track upsell revenue?
Yes. Revenue from upsells is tracked through Shopify's native order data, so you can report on it directly from your Shopify admin.
