Microsoft
Microsoft's Supplier Code of Conduct requires suppliers to "ensure accessibility" as a condition of doing business with the company, while internally Microsoft evaluates its own products against WCAG 2.2 Level AA and publishes Accessibility Conformance Reports (ACRs) for all major products and services.

What it is
Microsoft is one of the world's largest technology companies, with products spanning operating systems (Windows), productivity suites (Microsoft 365), cloud services (Azure), gaming (Xbox), and professional networking (LinkedIn). Microsoft has adopted WCAG 2.2 Level AA as its accessibility standard and publishes Accessibility Conformance Reports (ACRs) for its products using the Voluntary Product Accessibility Template (VPAT) format, covering Section 508 of the US Rehabilitation Act, WCAG, and ETSI EN 301 549 (the European accessibility standard).1
Microsoft evaluates product accessibility using the Department of Homeland Security (DHS) Trusted Tester program, supplemented by automated testing, manual testing, testing with assistive technologies (including screen readers), and functional testing by individuals with disabilities.2 The company also operates support channels through an Enterprise Disability Answer Desk for enterprise customers and a consumer Disability Answer Desk, and offers AskMA -- an AI-powered tool for finding accessibility feature information across Microsoft products.3
At the procurement level, Microsoft's Supplier Code of Conduct (SCoC) includes accessibility as a core expectation under "Demonstrating respect and inclusion." Suppliers are required to be aware of, attest to, train on, and adhere to the SCoC, which includes specific FAQ guidance on "accessibility expectations and resources" for suppliers.4 This creates a requirement-setting intervention that extends accessibility standards beyond Microsoft's own products into its supplier ecosystem.
Why it matters
When a company as large as Microsoft embeds accessibility requirements into supplier contracts, it creates a market-level effect: thousands of suppliers across 100+ countries must now consider accessibility as a condition of doing business, not as an optional add-on. This shifts accessibility from a product team's internal priority to a supply-chain requirement -- a form of market pressure that can cascade through the industry.
The publication of ACRs is equally significant. By making conformance reports publicly available, Microsoft enables procurement officers at government agencies, enterprises, and educational institutions to evaluate accessibility conformance before purchasing. This transforms accessibility from an invisible quality into a visible procurement criterion that can be compared across vendors. The QA testing infrastructure behind these reports -- Trusted Tester certification, assistive technology testing, user testing with disabled individuals -- represents a substantial ongoing investment in accessibility verification. Microsoft's Disability Answer Desk adds a post-deployment support channel to that testing and procurement story, giving customers a staffed route when live products still present accessibility barriers.3
Real-world example
Microsoft's conformance report system covers an extensive range of products: Azure, Dynamics 365, Intune, Office 365 (including Government and DoD variants), Windows Server, and more. Each report documents the degree to which a product supports WCAG Level AA success criteria, with specific explanations of any conformance gaps.2 A government procurement officer evaluating cloud platforms can compare Microsoft's ACR for Azure against competitors' reports -- making accessibility a decision factor alongside price, performance, and security.
The Supplier Code of Conduct's inclusion of accessibility is notable because it applies to all suppliers, not just technology vendors. Training, services, and consulting companies working with Microsoft must also attest to accessibility standards -- broadening the reach of accessibility expectations beyond the technology sector.4
What care sounds like
- "Our Supplier Code of Conduct requires all suppliers to ensure accessibility -- it's not optional."
- "We publish Accessibility Conformance Reports for every major product so procurement teams can evaluate us."
- "Our testing uses the DHS Trusted Tester program plus functional testing by individuals with disabilities."
What neglect sounds like
- "Accessibility conformance is an internal matter -- we don't share reports externally."
- "We don't have accessibility requirements for our suppliers."
- "Our products comply with accessibility standards, but we don't publish the evidence."
What compensation sounds like
- "I had to contact the Disability Answer Desk because the product feature I needed wasn't accessible out of the box."
- "The conformance report listed partial support for keyboard navigation, so I had to test it myself before recommending it to my agency."
- "Our vendor said they met Microsoft's accessibility requirements, but we had to verify independently."
