Building a Custom Cart Drawer in Shopify

The cart is your last, best chance to increase order value before checkout. A well-built custom cart drawer keeps shoppers on the page and gently encourages bigger orders — without hurting the experience.

What to build into a cart drawer

• A free-shipping progress bar ("You are $12 away from free shipping").
• In-cart upsells and complementary product suggestions.
• Quantity controls, gift options and order notes.
• Trust badges and clear, reassuring policy links.

Speed and smoothness matter

A cart drawer should open instantly and feel smooth, especially on mobile. Janky or slow carts frustrate shoppers at the worst possible moment. We build lightweight cart drawers that update in real time and never get in the way of the sale.

The payoff

Small, relevant incentives in the cart quietly raise average order value across every order — often outperforming discounts. Done well, a custom cart pays for itself quickly.
