Cart UX covers the design of the shopping cart — the holding state between product selection and checkout. A well-designed cart builds commitment, surfaces upsells without friction, and makes the path to checkout clear.
The cart is a transitional space. Shoppers arrive having made one decision — to add something — and leave either abandoning the session or committing to checkout. Cart design determines which outcome is more likely.
Modern Shopify carts take two primary forms: a dedicated cart page and a drawer (or slide-out) cart that layers over the current page. Each has trade-offs. Drawer carts keep shoppers in context and reduce navigation steps; cart pages offer more space for order summaries, upsells, and trust content.
Regardless of format, effective cart UX focuses on three things: confirming the shopper's selection clearly, making the checkout action unmissable, and using the available space to increase order value without creating friction.
Cart abandonment rates average above 70% across e-commerce. Many abandonments are inevitable — comparison shopping, price sensitivity, distraction. But a meaningful percentage are caused by poor cart UX: confusing totals, unclear shipping thresholds, too many steps to checkout, or a lack of confidence in the purchase.
Cart UX also directly influences average order value. Well-placed upsells, bundle recommendations, and threshold messaging ("Add $12 for free shipping") can increase AOV by 10–25% without any additional traffic spend.
