How do I apply a discount to a checkout upsell using Script Editor?
If you don't want to add a script and would like UpsellPlus to create the discount automatically, refer to the first section of Intro to discounts and use Shopify Functions instead.
Applying discounts to upsell products during checkout can incentivize customers to add more items to their purchase, thereby increasing your average order value. By utilizing Shopify's Script Editor, you can create scripts that automatically apply discounts to specific upsell offers.
To achieve this, we'll add a Shopify Script in just a few steps - no need for an engineer!
Step-by-Step Guide
Log in to Shopify Admin
Access your Shopify Admin panel using your credentials.
Install and Open the Script Editor App
If not already installed, download the Script Editor app from the Shopify App Store.
Open the Script Editor from your list of installed apps.
Create a New Script
Click on Create Script.
Choose the Line Item script type.
Insert the Discount Script
Copy and paste the following scripts into the editor:
For this example we'll choose between a percentage (%) off a product or amount ($) off a product discount.
For a Percentage Discount (e.g., 10% off):

If you’re not familiar with code, this will do the following:
IF the item added to the cart has “upsell_id” as a property
THEN apply a discount and display the message ‘Upsell Discount’ for the discount code when this product is added to cart
The “upsell_id” is added by the app to all items that get upsold, so we can track your upsell analytics.
Save and Publish in Script Editor to make your discounts live.
In this script, the parameters you can control are as follows:
Offer ID: Replace the e766cbff-060d-4ed7-9797-ccb9d2bdcf1a placeholder with the specific Offer ID from your UpsellPlus offer.
Discount Value: Adjust 0.90 to reflect the desired percentage discount (e.g., 0.85 for 15% off). For fixed discounts, change 500 to the desired amount in cents (e.g., 1000 for $10 off).
Discount Message: Customize "Upsell Discount" to the message you want customers to see, such as "Special Offer" or "Exclusive Deal".
You can find it in the app when you click into your upsell:
Shopify sets a limit on the number of Line Item scripts you can have live. If you want to combine multiple discounts into 1 script, you can use this threaded template:
Key Tips
Testing: Always perform thorough testing to confirm that discounts are applied correctly to the intended upsell offers.
