The post-purchase page is an underutilized opportunity in eCommerce. Customers have peak buying intent right after checkout, yet most stores only offer a simple Thank You page.
Post-purchase upsells reliably increase Average Order Value (AOV) by eliminating the friction of re-entering card and shipping info. Leveraging Shopify's native one-click post-purchase checkout extension, Boost offers merchants a clean setup to directly and measurably grow revenue from buyers already in a "yes" mindset.
To enable your first post-purchase offer, you have to set Boost as your post-purchase app in Shopify. Go to Shopify Admin > Settings > Checkout, find the Post-purchase page section, select Boost, and save.
Offers will not display on the storefront, even if Active in Boost, without this step.
Once that is done, the setup is just two steps.
You'll find the feature under Merchandising > Post-purchase offers in your Boost admin. Click Add new offer to get started.
Step 1: Set trigger conditions. This controls when your offer appears, based on what the customer just bought. You can choose from three options:
Step 2: Configure your offer. This is where you choose what to show the customer and how to present it. Key settings include:
A key note on branding: post-purchase offer styling automatically matches your Shopify checkout branding. There are no separate color or font controls in Boost for this, but you can update checkout branding directly in the Shopify checkout editor.
The storefront flow is simple: after payment, an offer appears. Clicking "Pay now" adds the product to the original order and charges the customer's card on file. Clicking "Decline" directs them to the Thank You page. Clean, simple, and no extra steps for anyone
Post-purchase upsell is available to Turbo version merchants only. For plan access:
A post-purchase offer performs best when it feels like a natural follow-on to the original purchase. Think complementary products, accessories, or consumables that add value to what the customer already chose. A generic offer visible after any purchase can work, but a targeted offer tied to a specific product or collection will almost always convert better.
A small incentive, such as 10 to 15 percent off, is often enough to tip a shopper who is already in a buying mindset. You do not need a steep discount here. The friction has already been removed by the one-click flow, so the product relevance does the heavy lifting.
The built-in countdown reinforces the urgency that this is a one-time moment. It does not need to be overly aggressive, but a 3- to 5-minute window is enough to create a clear sense that this offer will not reappear. Boost includes a built-in countdown timer, providing a complete solution within the app.
The default headings are a solid starting point. If you customize them, aim for copy that immediately communicates the product's value: what it is, why it pairs well, and what the deal is. Shoppers are deciding quickly, so clarity wins over cleverness.
If you run "Any product" as your trigger, take a few minutes to add exclusions for products where a follow-on offer would feel off. High-value items, subscription products, or products that are already a bundle are good candidates to exclude so your offer always feels relevant rather than random.
