Case Study: Redesigning a Food-Delivery App Checkout Reduced Cart Abandonment by 18%

Tech · 5 min read

The product team identified checkout as the top revenue leak after session replay and funnel analysis showed frequent drop-off between checkout and confirmation. Pain points were unclear fees, unexpected minimums, and a multi-step payment flow that lost context. The team prioritized quick wins: surface total cost earlier, combine related steps, and add resilient error messaging.

Designers created a condensed checkout prototype that moved fees and estimated delivery time into a persistent summary panel, combined address and tip steps, and introduced inline validation for payment failures with suggested fixes. Engineers implemented client-side checks to detect card expiry and autofill addresses from prior orders. The redesign minimized cognitive load and reduced surprise costs.

A two-week A/B test across three cities showed an 18% relative reduction in cart abandonment and a 7% increase in average order value, attributed to clearer cost visibility and simpler tipping. Post-launch qualitative interviews found that users felt more confident completing orders because they understood final costs earlier. The case reinforced a core lesson: reducing surprises in the last mile of purchase yields outsized conversion gains.
