Accessibility retrofits are expensive, slow, and demoralizing. Building accessibly from the start is almost free. Yet most product teams treat WCAG compliance as a checkbox to tick before enterprise deals close, rather than as a quality standard woven into every design and engineering decision.
The Business Case
Before we get to the ethics (which should be sufficient on their own), let’s talk about the business case. An estimated 1.3 billion people globally live with some form of disability. In the B2B SaaS world, enterprise procurement increasingly requires WCAG AA compliance as a vendor requirement. Accessible products are also more usable for everyone — the curb-cut effect is real.
Where Most Teams Fail
The most common accessibility failures we see in code reviews are not obscure WCAG edge cases. They’re fundamental: missing ARIA labels on icon buttons, form fields without labels, color contrast ratios that fail at 3:1 instead of 4.5:1, keyboard navigation that breaks on custom dropdown components, and modal dialogs that don’t trap focus correctly.
The Fix
Add axe-core or similar to your CI pipeline so accessibility violations block deployment the same way failing tests do. Run a keyboard-only test on every new feature before it ships — if you can’t complete the primary user flow with a keyboard, it doesn’t ship. Audit color contrast in your design system tokens, not component-by-component.
These changes take a day to implement. The alternative is a WCAG audit at Series B that finds 400 violations and a 3-month remediation sprint. Choose wisely.
