Accessibility-First Overhaul: Paxum's Fintech App Trade-offs and Wins

Tech · 7 min read

Paxum's accessibility audit surfaced systemic issues: low contrast ratios, tiny touch targets, and inconsistent focus states that broke screen reader flows. The product team committed to an accessibility-first redesign with three goals — WCAG AA compliance across critical flows, improved keyboard and screen reader navigation, and clearer information hierarchy for low-vision users. The scope targeted onboarding, payments, and account management first to balance impact and rollout effort.

Key design changes included larger, high-contrast typography with dynamic scaling, reflowable layouts that preserve information hierarchy at larger sizes, and touch targets expanded to meet accessibility standards. The team prototyped keyboard-first navigation and enriched semantic markup for screen readers, with explicit ARIA labels and logical grouping for multi-field forms. To preserve speed, they implemented progressive enhancement so users on modern browsers experience the full semantics without regressing legacy behavior.

Post-release analytics showed a 34% lift in successful completion of high-value tasks for users employing assistive technologies, and overall error rates during onboarding declined by 21%. Paxum accepted trade-offs: denser information layouts and some compact visual elements were removed to preserve tap targets and spacing, which meant fitting more data required deeper navigation. The product team documented these trade-offs and published an accessibility decision log to rationalize future feature design.
