1. What is Post-Purchase Upsell?

Post-Purchase Upsell (PPU) is your shortcut to instant extra revenue — without changing your checkout flow. Right after a customer completes payment, you get a final golden chance to show them an irresistible offer. 

• Why it matters for your store:

  • Boost Average Order Value (AOV) with one more item added after checkout.

  • Increase Conversion Rate (CR) for upsell products.

  • Capture new revenue that would otherwise be lost — all without disrupting the buying experience.

👉 Example: A customer buys a $100 jacket. Right after checkout, you show them matching shoes with 15% off, only available now. Many will say “yes” — and just like that, your order jumps from $100 to $130.

2. Eligibility

To make sure your offers display correctly:

• Your store must be using Shopify Checkout Extensibility.

• Shopify Payments (or another supported provider) must be enabled.

• Works with all Shopify plans that support post-purchase extensions.

• Some orders may not qualify (e.g., subscriptions, Buy Now Pay Later, or gift card checkouts).

💡 If your offer doesn’t appear, double-check the trigger conditions and eligibility settings.

3. Install & Activate the App

1. Install the app from the Shopify App Store → Shopify Admin → Apps → Search Post Purchase Upsell by EEG → Install.

2. Grant permissions → So the app can display offers, apply discounts, and track performance.

3. Enable the extension in your checkout → Settings → Checkout → Post-purchase page → Add app block → Select Post Purchase Upsell (PPU).

   

4. Run a quick test order → Complete a purchase to make sure your first offer shows up right after checkout.

4. Pro Tips Before You Create Your First Rule

• Choose products that naturally complement your best-sellers (e.g., phone case with phone, belt with jeans).

• Decide on your discount strategy (% or $) based on your average order value.

• Start simple: create one universal rule (all orders) to see results from day one.
