What is a post purchase upsell?
A post-purchase upsell is a special offer shown to a customer immediately after they complete checkout, but before they reach the thank-you page.
It allows customers to add an additional product to their order with a single click — without re-entering payment details.
Because the purchase is already completed, there’s no risk of disrupting the original sale.
How It Works
- Customer completes checkout and payment.
- A targeted upsell offer is displayed.
- Customer clicks “Pay now”
- The additional item is automatically added to the existing order.
- Payment is processed instantly using the same payment method.
The experience is seamless and frictionless.
Why Post-Purchase Upsells Work
Post-purchase offers convert well because:
- The customer has already decided to buy.
- Trust is established.
- Payment details are already secured.
- There is no interruption to checkout.
This makes it one of the most effective ways to increase Average Order Value (AOV).
What Can You Offer?
You can create offers such as:
- Complementary products
- Product upgrades
- Bundled deals
- Limited-time discounts
- Volume discounts
- Downsell offers (if the upsell is declined)
What Is a Downsell?
A downsell is shown if the customer declines the first upsell.
It typically includes a lower-priced or alternative offer to recover the opportunity.
Benefits of Post-Purchase Upsells
- Increase AOV without increasing traffic
- Boost revenue from existing customers
- No impact on checkout conversion rate
- Fully customizable and targeted
- Easy to set up and test
When Should You Use Post-Purchase Upsells?
Post-purchase upsells work best when:
- The offer is highly relevant to the original purchase
- The offer provides clear value
- The experience is fast and frictionless
- The pricing feels like a “no-brainer” add-on
Example
A customer buys a skincare serum for $40.
After checkout, they see:
“Add the matching moisturizer for 20% off — one click to add to your order.”
If accepted, the moisturizer is added instantly to their order without re-entering payment details.
Post-purchase upsells are one of the simplest and most powerful ways to unlock additional revenue from every order without hurting conversions.
