IAAP Audit

IAAP Audit provides structured accessibility audit services for organizations that need evidence-led review of websites, web applications, mobile apps, PDFs, documents, design systems, and critical user journeys. Our audits are designed for compliance, procurement, governance, and remediation teams that need clear findings, standards mapping, severity grading, screenshots, selectors, remediation guidance, and retest evidence. Audit scopes can be mapped to WCAG 2.1 AA, WCAG 2.2 AA, IS 17802, GIGW, Section 508, and EN 301 549. We also support SEBI digital accessibility audit preparation, including C1 platform inventory, C3 initial audit reporting, C4 remediation/retest evidence, and report-ready documentation for agreed scopes. IAAP Audit works with financial services, SaaS, education, healthcare, e-commerce, public-sector vendors, and compliance-sensitive digital teams that need practical accessibility review without vague reporting. Our focus is simple: identify barriers, document evidence, prioritize risk, guide remediation, and help teams move toward more accessible digital services.

Section 508 and WCAG are often mentioned together in ICT procurement.

They are related, but they play different roles.

The short version

Section 508 is the legal and procurement requirement for U.S. federal ICT accessibility.

WCAG is a technical accessibility standard used to evaluate web content and related digital experiences.

Why procurement teams need both

Procurement needs more than standards language.

Teams should request vendor accessibility evidence, review ACRs or VPATs, define testing responsibilities, validate important workflows, and require remediation for gaps.
