Kaching Cart integrates with Shopify’s native Search & Discovery app to show smart, cart-aware upsell recommendations, so the products you suggest are always relevant to what's in the customer's cart. This guide walks you through the full setup.
Why Search & Discovery?
Rather than building a recommendation engine from scratch, Kaching Cart plugs directly into Shopify's Search & Discovery app. It comes pre-installed on most stores and uses real order history and customer behaviour to surface relevant products — powerful recommendations without any extra setup.
Two recommendation modes
You can show upsell products based on what’s in the customer’s cart using two modes:
• Related — Shopify’s AI picks products based on order history and customer behaviour
• Complementary — you manually configure which products go together
Setting it up
Step 1. Connect Kaching Cart to Search & Discovery
In the Kaching Cart app, go to Product upsell → select Use AI recommendations → choose Complementary → click Open Search & Discovery.
Step 2. Navigate to Product recommendations
Inside Search & Discovery, navigate to Product recommendations. You'll see a list of your products. Select the one you want to configure upsells for.
Step 3. Add your upsell products
Click Browse and select the products you want to recommend. For example, if you add Nike Hoop 2 and Nike Hoop 3 as complementary products for Nike Hoop 1, those two will show as upsells whenever Nike Hoop 1 is in the cart.
For example, whenever Nike Hoop 1 is added to the cart, Nike Hoop 2 and Nike Hoop 3 will show as upsell recommendations.
Step 4. Keep in mind
Upsells only show for products you've explicitly configured. If a product hasn't been set up in Search & Discovery, no upsell will appear for it.
Prefer a hands-off approach?
Switch to Related mode and Shopify will automatically recommend products based on purchase patterns. No manual configuration needed.
