The Challenge
What A National E-Commerce Retailer Was Facing
A mid-market home goods retailer with approximately $18M in annual online revenue began receiving accessibility complaints from customers. An internal review found the checkout flow had never been tested with assistive technology. The engineering team commissioned an audit expecting 10 to 15 issues — the actual count was 63 failures concentrated in the cart, checkout, and order confirmation flows.
Most critically, screen reader users could not complete a purchase. Custom form elements, dynamic price updates, and the payment widget produced no meaningful output with JAWS or NVDA. Keyboard-only users hit a focus trap in the shipping address section from which there was no escape. Every assistive technology session in the checkout funnel was an abandoned cart.
Our Approach
How We Solved It
Audited the complete checkout funnel — product page through order confirmation — using automated scanning, keyboard-only testing, and JAWS, NVDA, and VoiceOver screen reader testing.
Mapped all 63 failures to specific checkout steps to quantify the percentage of sessions affected at each conversion point and prioritize by impact.
Rebuilt custom form components — quantity selector, address autocomplete, card expiry fields — using native HTML elements, eliminating the keyboard focus trap entirely.
Implemented aria-live regions for dynamic price and cart total updates so screen reader users hear price changes without losing their place in the form.
Fixed color contrast failures across all checkout CTA buttons — the original brand orange (#FF6B2B on white, 2.8:1) was adjusted to #C44A00, passing at 5.1:1 while remaining on-brand.
Corrected error message associations by connecting all validation messages to their respective fields via aria-describedby.
Added axe-core integration to the checkout CI pipeline as a deployment gate and established monthly automated monitoring scans with regression alerts.
The Outcome
What We Achieved Together
The accessible checkout launched 14 days after audit delivery. Within 60 days, the retailer observed a 12% checkout conversion improvement across all user segments — not just AT users. The same improvements that enabled screen reader access (clearer error messaging, logical tab order, properly labeled fields) reduced friction for mobile shoppers and keyboard power users simultaneously.
At an average order value of $82, the 12% conversion lift represented approximately $440,000 in estimated additional annual revenue — more than 15 times the combined cost of audit and remediation.
“We expected a compliance report. What we got was a business result. Our conversion rate went up 12%, and the improvements that made the site work for screen reader users turned out to be exactly what was slowing down our mobile checkout too.”
