Why accessibility by design costs less than late compliance

The most frequent objection to accessibility remains cost. It rests on a timing error: accessibility is expensive when treated late, not by nature.

The cost of late correction

Revisiting an already live service to make it accessible means revisiting structural choices, sometimes entire components, without being able to change the underlying architecture without rebuilding from scratch.

The cost of accessible design

Integrated from the framing stage, the cost of accessibility largely merges with the normal cost of design: choosing semantic HTML structure, compliant contrasts, consistent keyboard navigation costs almost nothing extra if done from the start.

A simple argument to present in a committee

• Fixing an accessible component once, before deployment: marginal cost
• Fixing the same component after deployment across 50 screens that use it: cost multiplied
• Never fixing it: legal risk and exclusion of a share of users

Accessibility is not a cost you can avoid, only a cost you can choose to pay once early, or several times late.
