Cart abandonment:
The silent killer of eCommerce conversions

accessiBe Team

In short (TL;DR)

Cart abandonment remains one of the most expensive—and preventable—problems in eCommerce. The average abandonment rate is 70.19%, translating to hundreds of billions in lost sales annually. While some of this loss reflects natural browsing behavior, most of it stems from friction: confusing checkout forms, hidden costs, inaccessible payment flows. These same friction points are also accessibility barriers. accessiBe research, in partnership with accessibilitychecker.org, found that 89% of the top 100 eComm sites in the U.S. have accessibility issues in their checkout flows. By addressing accessibility, brands don’t just mitigate risk—they recover revenue and build trust. The takeaway is clear: accessible checkout isn’t compliance overhead, it’s conversion optimization.

About the research

Our eCommerce trends survey, conducted with Qualtrics, non-profit leaders, and disability community organizations, captured insights from over 300 eCommerce leaders and members of the disability community. The findings reveal a clear connection between accessibility and revenue: most checkout friction points that drive cart abandonment are also accessibility failures, showing why accessibility must be treated as a core conversion strategy.

Why cart abandonment isn’t inevitable

For years, eCommerce leaders have accepted high cart abandonment rates as a cost of doing business. But the numbers reveal something else. Across 49 studies, the global average cart abandonment rate sits at 70.19%, making it the single largest source of lost revenue in digital commerce. Baymard researchers estimate that $260 billion in sales could be recovered simply by improving checkout usability.

Yet
72% of eCommerce leaders told us they are confident their checkout flows are “fully optimized.” With abandonment rates still above 70%, that confidence doesn’t match reality—and may be masking the flaws that drive customers away.

What many don’t realize is that these usability flaws are also accessibility failures. When a checkout form doesn’t announce errors to a screen reader, it doesn’t just frustrate—it excludes. When a payment interface can’t be navigated with a keyboard, it doesn’t just slow shoppers down—it makes completing a purchase impossible. Cart abandonment isn’t just a UX issue. It’s an accessibility problem hiding in plain sight.

Our survey of 300 eCommerce leaders reveals why these barriers persist. Nearly 1 in 4 admit assistive technologies don’t work on their checkout pages, and only 40% have conducted an accessibility audit in the past year. Checkout isn’t failing by accident—it’s failing because too few brands are testing it.

However, it's worth noting that I don't have the opportunity to evaluate the other factors
if I'm unable to complete my order,
so this is definitely critical!"

The high cost of friction

Cart abandonment has emerged as a defining conversion challenge for digital commerce leaders. The causes are remarkably consistent across industries:

  • 39% of shoppers abandon because of unexpected costs such as shipping, fees, or taxes
  • 18% walk away due to long or complicated checkout flows
  • 15% leave when sites crash or produce errors
  • 14% quit because they can’t calculate the total cost upfront

These everyday frictions add up to billions in preventable losses. Baymard estimates that improving checkout usability alone could recover more than $260 billion in annual sales. Addressing these root causes by simplifying flows, improving transparency, and ensuring reliability translates directly into recovered revenue and stronger customer trust.

70%+ of carts are abandoned, there is $260B in recoverable revenue from improving cart abandonment rates, 18% of abandonment rates are due to checkout complexity.

Industry giants have already reset expectations. Big players like Amazon and Walmart have streamlined checkout into a near-seamless experience with tools like one-click ordering, persistent carts, and wallet integrations. These approaches don’t just remove barriers—they train consumers to expect instant, frictionless purchasing. For online retailers, every extra step in the checkout flow now feels amplified, and every moment of hesitation risks sending customers elsewhere.


Abandonment rates aren’t a mystery;
they’re a measure of how much friction you’ve built into the customer journey


Where accessibility meets conversion

The very issues that drive customers to abandon their carts such as confusing forms, hidden errors, and clunky payment flows, are also common accessibility barriers. 

As we reported, nearly one in four retailers admit their checkout pages don’t work properly with assistive technologies like screen readers or keyboard navigation. For some shoppers that means friction. For others, it means they simply can’t complete the purchase.

An unlabeled form field frustrates one shopper but makes checkout impossible for another. A payment modal that glitches on mobile is inconvenient for some, but completely blocks those using assistive technologies. These aren’t separate problems; they’re two sides of the same coin. 

By addressing accessibility, brands not only meet compliance standards; they eliminate friction, recover lost sales, and build trust at the most critical moment in the customer journey.

Our survey confirms this link: 87% of eCommerce leaders believe that applying accessibility best practices to checkout would improve usability and reduce cart abandonment. Accessibility isn’t viewed as compliance overhead—it’s increasingly recognized as conversion optimization.

Accessibility shows its impact across the funnel:

  • For blind or low-vision shoppers, properly labeled fields and clear error messages make checkout possible
  • For people with motor disabilities, keyboard-friendly navigation and large, tappable buttons simplify completion
  • For neurodiverse shoppers, streamlined flows and real-time validation remove overwhelm and confusion

But when accessibility is overlooked, those same friction points become deal-breakers:

  • Unclear or missing error handling traps customers mid-checkout
  • Inaccessible payment gateways prevent entire groups from completing a purchase
  • Small touch targets and weak contrast exclude shoppers on mobile and those with vision or motor impairments

These aren’t minor usability quirks, rather they’re persistent design flaws that chip away at conversions. The brands that treat accessibility as core to conversion optimization will reduce abandonment, earn loyalty, and strengthen their competitive edge.

But awareness doesn’t erase risk. Nearly half (46%) of leaders told us they are concerned about failing shoppers with disabilities. That concern reflects a growing recognition that accessibility isn’t just a usability issue—it’s also a matter of brand trust, reputation, and regulatory exposure.

The perception gap

Our survey of eCommerce leaders shows a clear disconnect: many believe their checkout flows are optimized, yet abandonment rates and accessibility gaps tell a different story. Leaders cite the same friction points shoppers complain about—hidden fees, long forms, and unclear pricing—but often overlook the accessibility failures behind them. This perception gap explains why abandonment persists, even when brands think they’ve solved it.

What eComm leaders thinkWhat shoppers experience
✅ Checkout flows are “fully optimized”❌ Checkout fields without labels → screen readers can’t complete
✅ Main issues = hidden fees, long forms, unclear pricing❌ Payment modals not keyboard accessible → blocked purchases
✅ Confidence that UX fixes solve abandonment❌ Missing error messages → abandonment from small mistakes

How eCommerce brands can reduce cart abandonment through accessibility

  1. Audit your checkout for accessibility and usability gaps
    Many friction points only appear when tested by real users. Regular audits of checkout flows, both for usability and accessibility, help identify problems before they translate into abandoned carts.
  2. Simplify the checkout process
    The longer and more complex the flow, the higher the abandonment rate. Reducing unnecessary fields, enabling guest checkout, and providing real-time validation removes barriers and keeps customers moving forward.
  3. Ensure every step is accessible
    From the first form field to the final payment confirmation, the entire process must be usable by keyboard and screen reader. Inclusive design ensures no customer is blocked from completing their purchase and reduces friction for everyone.
  4. Use clear, accessible feedback mechanisms
    Unclear or missing feedback creates hesitation. Providing accessible error messages and confirmations reassures shoppers that their order is accurate and complete.
  5. Treat accessibility as part of conversion strategy
    Accessibility shouldn’t be an afterthought or a compliance checkbox. When integrated into conversion optimization, it reduces abandonment, recovers revenue, and builds lasting customer trust.

Accessibility turns abandoned carts into conversions

eCommerce sellers can reduce cart abandonment by treating accessibility as a conversion strategy, not a compliance task. The same fixes that make checkout inclusive, such as clear error handling, simplified forms, accessible payment flows, and transparent pricing, also remove friction for every shopper. 

By auditing checkout journeys, streamlining processes, and ensuring each step is usable by all, brands turn barriers into opportunities. The result isn’t just fewer abandoned carts, but stronger trust, loyalty, and long-term growth.
