The Cost of Retrofitting

Teams that treat accessibility as a post-launch concern consistently underestimate the cost of fixing it later. Retrofitting accessibility into an existing product typically costs 5-10x more than building it in from the start, because decisions made early in the architecture — component structure, state management, navigation patterns — have cascading effects that are expensive to undo.

But the case for accessible MVPs isn't just financial. It's about building better products from day one.

Accessibility Improves Usability for Everyone

The curb cut effect is the classic example: sidewalk ramps were designed for wheelchair users but benefit everyone — parents with strollers, delivery workers with carts, travelers with luggage. The same principle applies to digital products:

• Keyboard navigation benefits power users who prefer keyboard shortcuts, not just people who can't use a mouse
• Clear visual hierarchy and sufficient contrast help users in bright sunlight or on low-quality displays
• Descriptive link text helps everyone scan a page quickly, not just screen reader users
• Captions on video help people in noisy environments or those watching without sound

The Legal Landscape is Shifting

Web accessibility lawsuits have increased significantly year over year. The European Accessibility Act takes effect in 2025, requiring digital products sold in the EU to meet accessibility standards. In the US, the DOJ has consistently ruled that the ADA applies to websites and applications.

Starting with accessibility built in is far less risky than scrambling to comply after receiving a demand letter.

What an Accessible MVP Actually Looks Like

You don't need to achieve WCAG AAA compliance on day one. Focus on the fundamentals:

1. Semantic HTML. Use the right elements — buttons for actions, links for navigation, headings for structure. This single practice solves a surprising number of accessibility issues for free.
2. Keyboard accessibility. Every interactive element should be reachable and operable with a keyboard. Test by unplugging your mouse for 10 minutes.
3. Color contrast. Meet WCAG AA contrast ratios (4.5:1 for normal text, 3:1 for large text). Tools like the WebAIM Contrast Checker make this trivial.
4. Form labels. Every input needs an associated label. Placeholder text is not a label.
5. Alt text for images. Descriptive for informational images, empty (alt="") for decorative ones.

These five practices take almost no additional development time when applied from the start. They become expensive only when you have to go back and fix hundreds of components.
