RFP Ready: Questions Every Buyer Should Ask Accessibility Vendors in 2025

Accessibility RFP questions separate solutions that work from marketing hype. The accessibility vendor market has exploded—overlays, automated scanners, manual auditors, remediation platforms, training providers—each claiming to solve your accessibility problems. Without rigorous evaluation, organizations purchase tools that underdeliver, creating false confidence and continued liability.

The challenge is distinguishing substance from spin. Accessibility vendors know the right words: "AI-powered," "automated compliance," "WCAG conformance," "instant remediation." But these terms mean different things—or nothing at all—depending on implementation. Your RFP must cut through jargon to evaluate what solutions actually do.

This guide provides the WCAG vendor selection questions, evaluation frameworks, and red flags that help procurement teams, accessibility leaders, and IT buyers choose tools that fit their needs—not just their vendor's sales targets.

Buying Accessibility Solutions Is Hard

The Market Confusion

What should you ask accessibility vendors? Ask about technical approach (overlay vs. code-level), coverage scope (web, mobile, PDF), dev workflow integration, accuracy and false positive rates, support model, and how they handle issues automation can't detect.

The accessibility vendor landscape creates confusion:

Overlapping claims: Multiple vendors claim to provide "complete accessibility solutions" but deliver vastly different capabilities.

Technical opacity: Many solutions operate as black boxes. Buyers can't evaluate what happens technically without asking pointed questions.

Compliance ambiguity: Claims about "compliance" or "conformance" rarely specify what standard, what level, or what scope.

Category blurring: The line between scanners, remediation tools, overlays, and consulting is unclear, with many vendors straddling categories.

Marketing sophistication: Vendors invest heavily in marketing. Polished presentations don't correlate with product effectiveness.

Stakes of Wrong Decisions

Choosing the wrong accessibility vendor has consequences:

False confidence: Believing you're compliant when you're not, leading to continued legal exposure.

Wasted investment: Paying for capabilities that don't materialize or don't fit your needs.

Technical debt: Dependency on approaches (like overlays) that create long-term problems.

User harm: Users with disabilities continue experiencing barriers while you think you've addressed them.

Opportunity cost: Resources spent on ineffective solutions can't be spent on effective ones.

Key Dimensions to Evaluate in Accessibility Vendors

Coverage Scope

What platforms and content types does the solution address?

Web applications: Marketing sites, web applications, SPAs, e-commerce

Mobile: Native iOS, native Android, mobile web, responsive

Documents: PDFs, Word documents, presentations

Other digital: Email, embedded content, third-party integrations

Few vendors cover all areas effectively. Match coverage to your actual needs rather than pursuing illusory "complete" solutions.

Developer Experience and Workflow Integration

How does the solution fit your development process?

CI/CD integration: Does it run in your build pipeline? Which CI systems?

IDE integration: Can developers see issues while coding?

Code repository integration: Does it comment on PRs, create issues?

Ticketing integration: Does it connect to Jira, Linear, GitHub Issues?

Developer workflow fit: Does it support how your teams actually work?

Accessibility tools that don't integrate with developer workflow become shelfware. The best technical capabilities are worthless if developers don't use them.

Accuracy and False Positives

How reliable are findings?

Detection accuracy: Does it find real issues? What's the false negative rate?

False positive rate: How often does it flag non-issues? High false positives erode developer trust.

Issue categorization: Are severity levels meaningful and consistent?

Guidance quality: When issues are flagged, is the guidance actionable?

Ask for data on accuracy. If vendors can't provide specifics, that's information.

Security, Privacy, and Compliance

What are the data handling implications?

Data access: What code or content does the solution need to access?

Data storage: Where is data stored? For how long?

Compliance certifications: SOC 2, ISO 27001, GDPR compliance?

Security architecture: How is data protected in transit and at rest?

Privacy implications: Are user sessions recorded? What PII is collected?

Accessibility tools that scan your applications or code have significant access. Evaluate security accordingly.

Essential RFP Questions and What Good Answers Look Like

Technology and Approach Questions

"Do you fix code or layer on overlays?"

Good answer: "We identify issues in source code and provide specific remediation guidance showing exactly what to change and where. Our fixes become part of your codebase, not dependent on external scripts."

Red flag answer: "Our widget handles accessibility automatically without code changes." (This indicates an overlay approach with significant limitations.)

"How do you detect dynamic, state-based issues?"

Good answer: "We scan applications in multiple states, following user flows and evaluating dynamic content. Our testing simulates real user interactions including authentication and state changes."

Red flag answer: "We scan your HTML." (Static HTML scanning misses vast categories of accessibility issues in modern web applications.)

"What percentage of WCAG success criteria can your tool detect?"

Good answer: "Automated testing can reliably detect approximately 30-40% of WCAG success criteria. We're transparent about this limitation and complement automation with [approach to remaining issues]."

Red flag answer: "We detect all WCAG issues" or "We ensure complete compliance." (No tool detects all issues automatically. This claim indicates either misunderstanding or deception.)

Developer and Design Integration Questions

"How does this integrate with our CI/CD and repositories?"

Good answer: "We provide native integrations with GitHub Actions, GitLab CI, Jenkins, CircleCI, and Azure DevOps. Scans run on pull requests, comment findings directly in PRs, and can block merges for critical issues. Here's documentation on our integrations."

Red flag answer: "We provide a dashboard you can check periodically." (No workflow integration means accessibility becomes a separate process developers will ignore.)

"What do developers see when issues are found?"

Good answer: "Developers see the specific element, the WCAG criterion violated, why it's a problem for users, and exactly how to fix it with code examples. Findings appear in PR comments and IDE plugins."

Red flag answer: "Developers see a list of WCAG violations." (Lists without guidance don't lead to fixes.)

"How do you handle design-phase accessibility?"

Good answer: "We integrate with design tools and can scan prototypes, Storybook instances, and design system documentation. We also provide resources for accessible design patterns."

Red flag answer: "We focus on production code." (Missing design integration means catching issues later when they're expensive to fix.)

Human Expertise and Support Questions

"Do you provide guidance on prioritization and implementation?"

Good answer: "Our platform prioritizes findings by user impact and provides implementation guidance. For complex issues or strategic questions, customers have access to certified accessibility specialists (CPACC, WAS) who can advise on remediation approaches."

Red flag answer: "Our AI handles everything." (AI cannot handle strategic accessibility decisions or complex remediation planning.)

"What happens when we need help with issues automation can't detect?"

Good answer: "For manual testing, usability evaluation, and complex component review, we offer expert audit services. Our specialists use assistive technologies daily and can evaluate experiences automation misses."

Red flag answer: "Our automation covers everything you need." (This is factually impossible—automation has well-documented limitations.)

"How do you stay current with standards and regulations?"

Good answer: "Our team includes WCAG working group participants. We update our rules within weeks of specification changes and provide customers with regulatory updates relevant to their industries."

Red flag answer: Vague or no answer about standards currency.

Red Flags in Vendor Responses

Claims That Signal Problems

"100% compliance guaranteed": No tool can guarantee compliance. WCAG compliance requires human judgment for many criteria.

"Instant" or "overnight" compliance: Accessibility remediation takes time. Instant claims indicate overlay approaches or misrepresentation.

"AI solves everything": AI assists with accessibility but cannot fully evaluate or remediate accessibility issues.

"No developer involvement required": Code-level accessibility requires developer involvement. Claims otherwise indicate client-side manipulation (overlays).

"We've never had a customer sued after using our product": This is unfalsifiable and irrelevant. Overlay vendors have customers who've been sued.

Technical Red Flags

Can't explain technical approach: Legitimate vendors can explain how their technology works at a technical level.

No documentation or API specs: Mature products have documentation. Absence suggests immaturity.

No accuracy metrics: If they can't tell you false positive rates and detection coverage, they either don't know or don't want you to know.

Single-page-application limitations: If the vendor can't explain how they handle SPAs, React, Vue, Angular, etc., they may only work for static sites.

No manual testing component: Any vendor claiming complete accessibility coverage without manual testing is making false claims.

Creating an RFP Scoring Rubric

Evaluation Criteria and Weights

| Category              | Weight | Criteria                                                      |
|-----------------------|--------|---------------------------------------------------------------|
| Technical approach    | 25%    | Code-level vs. overlay, detection methodology, coverage scope |
| Developer integration | 20%    | CI/CD, PR comments, IDE support, ticketing                    |
| Accuracy              | 15%    | False positive rate, detection coverage, guidance quality     |
| Human expertise       | 15%    | Specialist access, manual testing, strategic support          |
| Security/compliance   | 10%    | Certifications, data handling, privacy                        |
| Scalability           | 10%    | Multi-property, multi-team, enterprise features               |
| Cost                  | 5%     | Total cost of ownership, pricing model fit                    |

Adjust weights based on your priorities. Organizations early in accessibility maturity might weight human expertise higher; mature programs might weight developer integration higher.

Scoring Template

For each criterion, score vendors 1-5:

1. Does not meet requirements
2. Partially meets requirements with significant gaps
3. Meets requirements adequately
4. Exceeds requirements in important ways
5. Exceptional capability, industry-leading

Multiply scores by weights, sum for total. But don't rely solely on numbers—qualitative assessment matters.

Frequently Asked Questions

What should we budget for accessibility tooling?

Budgets vary widely based on organization size and needs. Automated scanning tools range from $500-$50,000+ annually depending on scope. Enterprise platforms with full integration typically cost $20,000-$100,000+. Manual auditing services add $10,000-$100,000+ depending on frequency and scope. Consider total cost of ownership including implementation and training.

Should we buy one comprehensive solution or best-of-breed components?

Both approaches work. Integrated platforms reduce procurement complexity and ensure component compatibility. Best-of-breed components allow optimizing each capability but require integration effort. Most organizations start with an integrated platform and add specialized tools as they mature.

How do we evaluate vendors' accuracy claims?

Request proof: false positive rates, detection benchmarks, third-party validation. Ask for trial access and test against known accessibility issues in your environment. Check references from similar organizations. Be skeptical of claims without supporting data.

Should we require demos with our actual code/sites?

Yes. Generic demos show best-case scenarios. Request proof-of-concept with your actual web properties. This reveals how the tool handles your specific technology stack, complexity, and scale. Most vendors offer trial periods or POCs for enterprise customers.

How do we compare overlay vendors to code-level solutions?

They solve different problems. Overlays provide some surface-level fixes quickly but can't address structural accessibility issues. Code-level solutions fix root causes but require development effort. For most organizations, code-level approaches provide better long-term value despite higher initial effort. See our article on overlays vs. code fixes for detailed comparison.

Conclusion – Choose Tools That Fit Your Stack and Strategy

Accessibility RFP questions reveal what vendors actually deliver versus what they claim. Rigorous evaluation protects you from solutions that create false confidence while failing to address real accessibility issues.

Effective vendor evaluation requires:

• Clear requirements understanding what capabilities you actually need
• Pointed questions that cut through marketing to technical reality
• Red flag awareness recognizing claims that indicate problems
• Structured scoring that enables consistent comparison
• Practical testing validating capabilities against your actual environment

The right accessibility vendor accelerates your accessibility program. The wrong one wastes resources and leaves you exposed. Invest the time in rigorous evaluation—the cost of wrong decisions far exceeds the cost of thorough procurement.
