Why add upsell blocks to your Shopify checkout?

Checkout is the highest-intent moment in a buyer's journey. The customer has already decided to purchase — they've added items to their cart, entered their shipping address, and are about to confirm payment. Adding a relevant product recommendation at this exact moment is fundamentally different from an on-site popup or a retargeting ad: the customer is already committed.

Checkout upsell blocks render inside the native Shopify checkout, between cart items and the Place Order button. Customers can add a recommended product with a single tap — no re-entering payment details, no navigating to a separate page, no losing their place in the flow. The result is a frictionless add that would not have happened otherwise.

The post-purchase upsell goes even further. It appears on the thank-you page after the order is confirmed, when payment is already authorised. At this moment, customers are in a "yes" mindset — and a one-click accept requires zero additional commitment. Merchants who deploy both checkout and post-purchase upsells consistently see AOV lifts of $15–$30 per order.

How it works

Placed at the highest-intent moment

Upsell blocks render between cart items and the Place Order button — where the customer's attention and intent are at their peak.

One-tap add to order

Customers add recommended products without leaving checkout or re-entering payment details. The lower the friction, the higher the acceptance rate.

Smart display conditions

Show upsells only when cart total, customer tags, specific products, or item count match your rules. Irrelevant offers shown to the wrong customers kill conversion.

Post-purchase capture on the thank-you page

The thank-you page upsell activates after the order is placed. Payment is already authorised — customers can accept with a single tap, no checkout re-entry.

Upsell blocks included

Everything you need to run upsells across checkout, thank-you, and order status pages — all in one install.

Upsells & Cross-sells

CheckoutThank You Page

Show personalised product recommendations right inside the checkout flow. Customers add with one tap — no re-entering payment details, zero friction.

Post-Purchase Upsell

Post-PurchaseThank You Page

Capture more revenue after the sale. Offer a one-click upsell on the thank-you page — payment is already authorised, so customers accept in seconds.

Free Shipping Bar

CheckoutOrder Status

Show customers exactly how close they are to free shipping. A simple progress bar that consistently lifts average order value without any effort.

Free Gift

Checkout

Automatically offer a free gift when cart conditions are met — minimum spend, specific products, or customer tags. Drives larger carts effortlessly.

Use cases

Checkout upsells are versatile. Here are the most effective ways Shopify merchants use them.

Accessory pairings

Suggest a protective case with every phone, a cleaning kit with every appliance, or a matching belt with every pair of shoes. Relevant pairings convert at 3–5x generic recommendations.

Volume discounts

Show 'Add a second unit for 20% off' as a checkout upsell. Volume offers presented at the moment of purchase consistently outperform the same offer shown on the product page.

Post-purchase complementary products

Offer a complementary item on the thank-you page after the initial sale. With payment already authorised, the one-click accept rate is significantly higher than pre-checkout offers.

Free shipping threshold push

Show a low-cost upsell that pushes the customer just over your free shipping threshold. Pair with the Free Shipping Bar so customers can see exactly how close they are.

Frequently asked questions

Will upsell blocks slow down my checkout?

No. All blocks render through Shopify's native checkout extensibility API, which is optimised for performance. Blocks load asynchronously and do not affect Shopify's checkout speed metrics.

Can I show different products to different customers?

Yes. Display conditions let you target by cart total, customer tags, specific products in cart, item count, and more. Each upsell block can have its own independent conditions.

What's the difference between a checkout upsell and a post-purchase upsell?

Checkout upsells appear inside the checkout flow before the order is placed — the customer can add items and then complete their purchase. Post-purchase upsells appear on the thank-you page after the order is confirmed, when payment is already authorised. Both block types are included.

Do upsell blocks work on all Shopify plans?

Yes — on any Shopify plan that supports checkout extensibility: Basic, Shopify, Advanced, and Plus. You do not need Shopify Plus to use checkout upsells.

Can I apply a discount to my upsell products?

Yes. Each upsell block supports an optional discount code that is automatically applied when a customer adds the upsell product. You can also show a visual discount badge (e.g. '20% OFF') on the product card.

How many products can I show in the upsell block?

The checkout upsell block supports up to 6 hand-picked products. You choose the products, the layout (card or list), and the display conditions in the app admin.
