How a 3-step checkout redesign recovered $400K in abandoned carts

A mid-market fashion brand was generating solid traffic and strong add-to-cart rates, but their checkout completion rate was just 28%. For every 100 people who added an item to their cart, 72 left without buying. At their average order value of $85, that represented roughly $400K in monthly lost revenue.

We analyzed the existing checkout flow and found the usual culprits amplified to an extreme degree: a mandatory account creation step, a 5-page checkout sequence, surprise shipping costs revealed only at the final step, and a payment form that did not support Apple Pay or Google Pay — methods that now account for over 30% of mobile transactions.

The Redesign

Our redesign compressed the checkout into a single scrollable page with three clear sections: shipping, payment, and review. Guest checkout became the default. Shipping costs were displayed from the cart page onward so there were no surprises. And we added Apple Pay, Google Pay, and Shop Pay as one-tap payment options at the top of the payment section.

We also added smart defaults to reduce friction. Returning visitors had their shipping address pre-filled. The shipping method defaulted to the most popular option rather than the cheapest. And we showed estimated delivery dates instead of shipping speed labels — customers care about when it arrives, not whether it is 'Priority' or 'Express.'

The Impact

After 30 days, checkout completion rate jumped from 28% to 51%. Mobile checkout completion — which had been a dismal 19% — climbed to 44%, largely driven by one-tap payment adoption. The recovered revenue exceeded projections, and the client reinvested the gains into expanding their product line.

The lesson: checkout optimization is not glamorous, but it is often the highest-ROI design work you can do for an e-commerce business. A 1% improvement in checkout completion is worth more than a 10% increase in traffic.
