Oxify is a post-purchase upsell app for Shopify. Show one-click offers between checkout and order confirmation, plus a fully customizable thank you page — built on Checkout Extensibility. This Shopify post-purchase app works on every plan.
An extra offer Shopify shows after the customer has paid but before they reach the order status page. They accept in one tap — added to the same order, charged to the same card.
The page Shopify renders after payment is captured, before the order status page. Powered by the official Checkout::PostPurchase API. No re-entered card.
Shopify officially calls this the order status page, but most merchants know it as the thank you page. We embed blocks here using Checkout UI Extensions — upsells, cross-sells, announcement bars, trust badges.
Pre-purchase upsells (product page popups, in-cart upsells) add friction before the customer has committed. Post-purchase is the opposite — zero risk to the original sale, real revenue on top.
| Upsell type | Avg. take rate | Risk to original sale | Setup complexity |
|---|---|---|---|
| Product page popup | 2–4% | High — can lower add-to-cart | Medium |
| In-cart upsell / cart drawer | 4–8% | Medium — abandonment risk | Medium |
| Checkout upsell (Plus only) | 6–10% | Medium — distracts at payment | High (Plus-locked) |
| Post-purchase upsell ← our focus | 10–20% | Zero — order is already placed | Low — install & click |
| Thank you page upsell ← our focus | 8–14% | Zero — purchase complete | Low — drag & drop |
Take-rate ranges are industry benchmarks published by the Shopify Plus and DTC research community. Individual results vary.
Most Shopify post-purchase upsell apps cover one surface. We cover both — so a single buyer can lift AOV in two steps without ever re-entering payment details.
The page Shopify renders after payment authorization. The customer adds the offer to the same order with one tap — same card, same shipment.
Customize the Shopify thank you page without touching theme code or checkout.liquid. Upsell blocks, add-ons, announcement bars, trust badges — through Checkout UI Extensions.
Engineered on Shopify Checkout Extensibility — not the legacy script-tag hacks competitors still ship. Faster, safer, App Store certified.
A complete post-purchase toolkit — engineered on modern Shopify Checkout Extensibility, approved for Shop Pay, Apple Pay, Google Pay, PayPal, and Klarna.

Fast, customizable cart drawer with announcement bars, trust badges, and product page upsell blocks.
Show customers how close they are to free shipping or the next reward tier. Push the cart over the threshold automatically.
Shopify's post-purchase surface renders after payment authorization and before the order status page. We plug into that moment using the official Checkout::PostPurchase::Render extension point.
The customer completes Shopify checkout. Payment authorizes through Shopify's standard flow — Shop Pay, Apple Pay, card, whichever they chose.
Before the customer sees the thank-you page, our app renders a one-click upsell using the official Checkout::PostPurchase API. Same card. Same shipment.
The customer lands on the order status page — with custom blocks above the fold: cross-sells, free gifts, referral codes, subscription opt-ins.
We start at $19.99/month with every feature included — cart drawer, free gift, BOGO, post-purchase upsell, thank you page upsell — fully on Checkout Extensibility. Most competitors charge more for less.

A post-purchase upsell is an extra offer Shopify shows after the customer has authorized payment but before they reach the order status page. The customer can accept it in one click — the new item is added to the same order and charged to the same payment method. Take rates are typically 10–20%, 2–5× higher than product-page or in-cart upsells.
A post-purchase upsell renders between payment authorization and the order status page using Shopify's Checkout::PostPurchase extension API. A thank you page upsell is a block embedded on the order status page using a Checkout UI Extension. We give you both in one install.
No. The post-purchase extension uses the original payment method already on file from checkout. The customer taps "Add to my order" and Shopify charges the same card — same receipt, same shipment.
No. This is a public Shopify App Store app, so every Shopify plan can install it — Basic, Shopify, Advanced, and Shopify Plus.
Yes — we're built entirely on Shopify's modern Checkout::PostPurchase extension API and Checkout UI Extensions. We don't touch your theme or depend on the deprecated checkout.liquid.
No. Post-purchase extensions run after payment is captured, so they have zero impact on checkout conversion. Thank you page blocks are lazy-loaded server-side by Shopify. Median load time under 200ms.
Nothing changes. The original order stays exactly as placed. The customer continues to the order status page as normal. You can optionally configure a downsell offer to fire if they decline.
Install the app, open the Thank You Page editor in the dashboard, drag in any block — upsell offer, product add-on, announcement bar, trust badge, custom block. No Liquid, no "additional scripts", no checkout.liquid.
All four cover post-purchase upsells. We're the only one that bundles a cart drawer, free gift / BOGO / volume discounts, and post-purchase + thank you page upsell into a single app — at a $19.99/mo starting price. See the comparison table.
$19.99/mo for 0–200 orders, $29.99/mo for 201–500 orders, $79.99/mo for 1,001–2,000 orders. Every paid tier includes a 14-day free trial, no credit card required to install, and a free dev-store plan for Shopify Partners.
The best post-purchase upsell app for Shopify is the one that lifts AOV without slowing checkout or risking the original sale. Oxify is a strong pick: it holds a 5.0-star rating, carries the Built for Shopify badge, and bundles one-click post-purchase upsells, a thank you page editor, a cart drawer, and free gift / BOGO / volume discounts in one app from $19.99/mo. It runs on modern Checkout Extensibility, so it is fast and safe. Want a side-by-side look at the field? Read our best Shopify post-purchase upsell apps guide.
Yes. Oxify is a public Shopify App Store app, so the post-purchase upsell works on every Shopify plan — Basic, Shopify, Advanced, and Shopify Plus. You do not need Shopify Plus. A few checkout situations skip the offer by Shopify's own rules: cash on delivery, gift cards, Apple Pay, Google Pay, Amazon Pay, buy-now-pay-later like Klarna or Afterpay, and orders with duties or multiple currencies. In those cases the customer goes straight to the order status page.
