The Upsells module enables customers to add related or complementary products to their cart with a single click.
Product Selection
AI Recommended Upsells
Enable this setting to use Shopify's Product Recommendation Algorithm to suggest upsells automatically.
Recommendation Algorithm
This option appears only if AI recommendations are enabled. Choose your desired Recommendation Intent: Recommendation Intent:
Related products
Displays similar or substitutable products under a "You might also like" section.
Important: Products must share a collection to be considered "related."
Complementary products
Displays add-ons or accessories under a "Pair it with" section.
Note: Complementary intent must be manually configured in the Shopify Search & Discovery app. The algorithm only auto-generates for “Related” products.

Smart Variant Matching
When enabled, Upcart will utilize AI to pre-select a variant that matches one already in the customer’s cart, streamlining the upselling process and enhancing consistency. This feature automates variant selection based on factors such as size, color, or style, eliminating the need for manual configuration and simplifying the shopping experience.
For instance, if a customer has selected a black shirt in their cart, the upsell process may suggest or auto-select matching black pants in the upsell offer. If no matching variant is identified, the customer will still have the option to manually select the desired variant.

Manual Upsells Configuration
Manual upsells can be set up only when AI Recommended Upsells is disabled.
Click Configure Manual Upsells.
Click Add New Upsell to add a row with:
Trigger Product(s)
Specific Trigger: Choose at least one product that must be in the cart.
All Products: Display the upsell when any product is in the cart.Upsell Product(s)
Select the product(s) to show when a trigger product is in the cart.
Order of Upsell Appearance
Upsells are evaluated from top to bottom. To arrange the priority of rows, drag and drop them in the Cart Editor under the Configure Manual Upsells section. The system displays upsells based on their top-to-bottom arrangement in the Cart Editor.
If Products A and C are in the cart, and you’ve set upsells for each, both B and D will be shown.
When selecting multiple upsell products in a single upsell row, the order of product selection will determine the order of their appearance in the cart, top to bottom.
Displaying Reviews
Upcart can display product reviews on upsells and product recommendations to help customers make informed purchase decisions. Reviews are not shown on standard cart line items.
Upcart uses the Shopify Storefront API to read review data stored in product metafields. Because of this, reviews will only appear if your review app exposes product review data in a format the Storefront API can access.
Supported review apps
At this time, Upcart supports reviews from the following apps:
Shopify Product Reviews
https://apps.shopify.com/product-reviewsGrowave
https://apps.shopify.com/growave
Only these apps are officially supported, as they store review data in compatible product metafields.
If reviews aren’t appearing, make sure you’re using one of the supported apps and that the products shown in upsells or recommendations have reviews available.
