Grow every order with in-cart upsells.
Cartylabs puts AI-powered product offers, spend rewards, and bundles inside the cart drawer, where shoppers are already deciding what to buy. No pop-ups. No interruptions. Just more revenue.
The cart is the highest-intent page on your store.
A shopper who has opened the cart is seconds away from checkout. They've already decided to buy and are simply reviewing. That's the perfect moment for a well-placed product suggestion.
Cartylabs places upsells as a natural section inside the cart drawer, not as an interstitial that interrupts the browse flow. Shoppers see it as helpful. Conversion rates reflect that.

Six cart upsell strategies, one app.
Enable as many as you need. All run simultaneously without conflicts.
Product recommendations
Show complementary items based on what's in the cart. Cartylabs analyses cart contents and purchase history to surface the most relevant product for each shopper.
Frequently bought together
Bundle complementary items with one-click add. Works especially well for consumables, accessories, and refillable products.
Spend threshold rewards
A progress bar that shows how close the shopper is to free shipping or a free gift. Nudges up cart value without discounting.
Subscription upsell
Offer a "subscribe & save" upgrade right before checkout, at the point of highest intent. Convert single orders into recurring revenue.
Volume discount upsell
Prompt shoppers to buy two or three units to unlock a per-unit discount. Works well for high-margin consumables.
Shipping protection
A one-click opt-in that adds a small shipping protection fee. Converts at 20–40% with zero fulfilment cost.
Everything works together.
Cart upsells are one piece. Cartylabs also handles the cart drawer UI, slide-out animations, sticky cart bar, and checkout conversion features. All in one app.
What is a Shopify cart upsell?
A cart upsell is a product offer shown to a shopper inside the cart, before they reach the checkout. Because the shopper is already in "buying mode", cart upsells convert far better than homepage banners or pop-ups.
Why are in-cart upsells better than pop-ups?
Pop-ups interrupt the browsing flow and are dismissed by most shoppers. In-cart upsells appear inside the space the shopper is already reviewing before checkout, so they're seen as a helpful suggestion rather than an intrusion.
How much AOV lift can I expect?
Cartylabs merchants typically see 15–25% AOV improvement within 30 days of enabling cart upsells. Results vary by product category and offer quality, but the impact is measurable and usually visible within 7 days.
Can I control which products are upselled?
Yes. You can use AI-automated recommendations, manual rules ("show product X when product Y is in cart"), category-level rules, or a mix of all three.
Does the cart upsell slow down my store?
No. Cartylabs loads asynchronously and the recommendation logic runs on our edge infrastructure. Your store's Core Web Vitals are not affected.
Do I need the Growth plan for cart upsells?
AI-powered recommendations and bundles are on the Growth plan ($9.99/mo). The spend-threshold free-gift bar is also Growth-only. See the pricing page for a full breakdown.
