Sellify Post Purchase Upsell is a free Shopify app for adding one-click upsells after checkout, on both the post-purchase and thank-you pages. It carries Shopify's Built for Shopify badge, so I was curious how polished a free app would feel — I set it up on a test store to find out.
Setting it up
Setup is no-code and quick. Rather than a single offer, I could build multi-step upsell and downsell funnels that fire on the thank-you page, layer in a discount and a countdown timer, and let the app's AI suggest the products. Shoppers accept in one click, so there's no re-entering payment or shipping details.
Key features
- One-click post-purchase and thank-you-page upsells: Capture more AOV right after the order.
- Upsell and downsell funnels: Chain multiple offers based on what the customer accepts or declines.
- Discounts and countdown timers: Add urgency to each offer.
- AI recommendations: Let the app suggest relevant products automatically.
- Optional checkout placement: In-checkout upsells are available for Shopify Plus stores.
Pricing
Sellify is free, which makes the Built for Shopify badge especially welcome — you get an app that meets Shopify's performance and design standards without a subscription.
Rating and reviews
It holds a 5.0 rating, though from a small number of reviews so far; the ones there praise the experience and the fast, no-wait support. That matched how smoothly setup went for me.
What could be better
It's a young app, so the review base is small and it's less battle-tested than the big names. As with any post-purchase tool, offers only appear for orders paid with supported payment methods, so some express or third-party checkouts won't see them.
My verdict
Sellify is a generous free option: funnels, discounts, timers, and AI recommendations are a lot to get at no cost, and the Built for Shopify badge is reassuring. If you want a no-cost way to run proper post-purchase funnels, it's an easy one to try — just keep in mind it's still building its track record.
