The Challenge
The retailer's 5-step checkout flow had a 68% abandonment rate. For users relying on screen readers or keyboard navigation, the rate was even higher — an estimated 89%. Form validation errors were invisible to assistive technology, payment fields trapped keyboard focus, and the progress indicator was purely visual.
The business impact was clear: every percentage point of checkout completion represented significant revenue.
Our Approach
Phase 1: Audit & User Research (Weeks 1-2)
We mapped the entire checkout flow, documenting every accessibility barrier. We then conducted usability sessions with users who rely on screen readers, keyboard-only navigation, and voice control to understand the real-world impact.
Phase 2: Accessible Redesign (Weeks 3-5)
The redesign addressed every barrier while maintaining the retailer's brand identity:
- Step indicator rebuilt as an accessible progress tracker with
aria-currentand descriptive labels - Form fields restructured with programmatic labels, inline error messages linked via
aria-describedby, and real-time validation announcements - Payment section rebuilt to eliminate focus traps in third-party iframe integrations
- Order summary made collapsible with proper
aria-expandedstate management - Focus management between steps using
requestAnimationFramefor reliable focus placement
Phase 3: Development & Testing (Weeks 6-8)
We implemented the redesign in React with TypeScript, using custom hooks for focus management and form state. Every component was tested against WCAG 2.1 AA with automated and manual methods.
Results
The accessibility-first redesign delivered business results that exceeded the original brief:
- 34% increase in checkout completions across all users
- 52% reduction in cart abandonment at the form validation step
- Near-zero assistive technology abandonment (down from 89%)
- 28% reduction in checkout-related support calls
Key Takeaway
Accessible checkout design is conversion optimization. When you remove barriers for users with disabilities, you remove friction for everyone. The ROI on this project paid for itself within the first quarter.
