Do I need Shopify Plus to use Aftersell post-purchase upsells?

No. Post-purchase upsells are available on all Shopify plans — Basic, Shopify, Advanced, and Plus. This is a key difference from checkout upsells, which are a Shopify Plus-only feature. Any Shopify merchant can install Aftersell and launch post-purchase offers today.

What is a one-click post-purchase upsell and how does it work?

A one-click post-purchase upsell is an offer shown to a customer on the page immediately after they complete their order. Because their payment details are already authorized, they can accept the offer with a single click — no re-entering card information, no new checkout flow, no friction. The upsell item is added directly to their original order. Aftersell places these offers natively within Shopify's post-purchase extension, so they load fast and feel seamless.

What is Smart Funnels and how is it different from A/B testing?

Smart Funnels is Aftersell's AI-powered offer optimization engine. Where A/B testing requires you to define two variants and manually analyze results, Smart Funnels automatically generates, tests, and rotates up to 6,000+ offer variations — across products, pricing, discounts, and page layouts — and continuously learns which performs best for each customer segment in real time. You set the parameters once; Smart Funnels handles the optimization without ongoing manual input. No other major Shopify post-purchase upsell app offers this capability.

What targeting triggers does Aftersell support for post-purchase offers?

Aftersell supports a comprehensive set of targeting triggers, combinable with AND/OR conditional logic: specific products purchased, product collections, cart value, order count, customer tags, UTM source and campaign, shipping method selected, discount codes used, and random sample (for broad testing). This means you can show a completely different offer to a first-time buyer who came from a Meta ad versus a repeat customer who used a loyalty discount — all without any developer involvement.

Can Aftersell upsell customers to a subscription after purchase?

Yes. Aftersell supports subscription upsells in post-purchase offers, allowing you to present a one-time buyer with the option to convert their purchase to a recurring subscription in a single click. You can also set up replacement upsells that swap a single product in the original order for a subscription version. Integrates with leading subscription platforms including Recharge, Loop, and Stay AI.

How do I switch to Aftersell from another post-purchase upsell app?

You can install Aftersell from the Shopify App Store or book a migration call to get assistance with switching from another post-purchase upsell app.
