Folks rarely set out to build something inaccessible. But tight deadlines, understaffing, and budget constraints can push shift-left accessibility activities to the sidelines, creating gaps and missteps that are harder to address later. Issues like a button without a label, an image missing ALT text, or an unlabeled form field. On their own, they sound minor, but left unresolved, they build up into a backlog. That backlog is called accessibility debt.
And that backlog can make it difficult, or even impossible, for many people to use your website, app, or software. Not to mention, the longer it goes ignored, the harder and more costly it becomes to fix.
How Does Accessibility Debt Happen?
Accessibility debt can build up in small ways:
- Moving files from concept to development without accounting for accessibility.
- Reusing existing patterns and components to save time, without anyone evaluating their accessibility, can replicate the same accessibility issues from project to project.
- Tight timelines can push testing to just mouse and keyboard, leaving other ways of interacting - screen readers, for example - out of the process.
- A lack of accessibility training and expertise can make issues harder to spot.
Over time, these shortcuts add up, and what started as a few overlooked issues can become a much larger accessibility problem.
Real-World Consequences
Accessibility debt isn't simply a backlog of technical issues. It's the accumulating cost of leaving them unresolved. The longer they remain, the more they can affect your users, designers and developers, budgets, timelines, and organizational risk. Accessibility debt has real operational consequences, such as:
- Loss of user trust.
When prospective customers, students, employees, donors, or community members repeatedly encounter an inaccessible digital experience, they may stop relying on your website or choose another organization’s website that is easier to use, possibly causing you to lose revenue as well. - Backlog becomes harder to prioritize.
As the number of unresolved issues grows, it becomes harder to distinguish between quick wins, systemic problems, and issues that have the greatest impact on users. - Support requests increase.
People who can't complete tasks independently may need to contact support, request alternative formats, or ask someone else for help. - Compliance and legal risk can increase.
Constant accessibility issues can contribute to user complaints, investigations, or legal action, depending on the organization and applicable requirements. - Time spent fixing the same issues repeatedly.
Without addressing the underlying process or pattern, designers, developers, and content creators may keep encountering and repairing the same or similar accessibility issues. - Remediation competes with new priorities.
Accessibility fixes have to share limited time and resources with new features, redesigns, content initiatives, and other organizational priorities. - Development and project schedules get disrupted.
Last-minute accessibility fixes can force designers, developers, and content creators to revisit completed work, possibly delaying launches or releases. - Accessibility work becomes harder to defend.
If accessibility wasn't established as part of the project requirements, standards, or the Definition of Done, you may find yourself having to make a new case for why an issue needs to be fixed after the work was already considered completed.
The biggest consequence of accessibility debt is the people it leaves behind. People who can’t access information, complete a task, apply for something, make a purchase, register for an event, or participate because a digital barrier gets in their way. And often, the people most affected can’t even get far enough into the experience to report the problem. So, how do you determine your accessibility and start paying down that debt?
How To Uncover and Start Eliminating Accessibility Debt
Accessibility debt won’t resolve itself. The first step is understanding where those barriers exist, then putting a plan in place to address them.
The first step is understanding the scope of the problem, and that starts with thorough testing. Automated tools like DubBot can quickly flag common accessibility issues, and manual testing like using keyboard navigation, screen readers, and focus-order checks helps uncover barriers automation can miss.
Next, track the problem like any other metric: open violations by severity, unaudited components, and meeting accessibility standards on every new feature, so you don't create new issues while fixing old ones. Prioritizing the most visible or disruptive barriers helps focus limited time and resources where they make the biggest difference, while also helping make the case for continued accessibility work.

Give the whole team, not just one specialist, working knowledge of accessibility basics and remediation best practices. Make training a regular, required activity for designers, developers, and content creators across your organization.
Build accessibility into design and code reviews, not a separate audit at the end. This is what shifting left in accessibility looks like. Make accessibility part of the project process from the very beginning. From project requirements to acceptance testing.
Review your content strategy and make sure you have included accessibility. True strategic planning integrates accessibility alongside audience and persona research, positioning accessibility and inclusion as core business insights rather than afterthoughts.
Most importantly, include people with disabilities in the testing process. They’ll find what a checklist can’t. Automated and manual testing can tell you whether specific accessibility requirements are met. Still, people with disabilities can identify real-world usability issues and tell you whether a website actually works for them, where the experience breaks down, and why. Involving people with disabilities brings lived experience into the development process, with their feedback shaping design, content, functionality, and testing practices while helping identify and address accessibility issues before they become harder and more expensive to fix.
Going From Accessibility Debt to Accessibility System
Think of accessibility as a system, not a one-time fix for accumulated debt. Fixing today’s issues is important, but it’s only part of the work. Lasting accessibility comes from building it into how your organization operates using clear strategy, shared rules, defined ownership, and ongoing oversight. Strategy sets the direction. Policy sets the expectations. Continuous monitoring provides the ongoing feedback needed to identify new issues as your website changes. Together, they turn accessibility from a backlog to manage into an ongoing practice.
