A11yProof

AI-powered accessibility scanner with multi-site management. Agency plan covers 25 sites for $199/month.

Pros

✓ 25 sites for $199/month — under $8/site
✓ AI-generated code fix suggestions per client site
✓ Criterion-level compliance reports for each client
✓ Month-to-month billing, no annual lock-in

Cons

× No white-label reporting on current plans
× Newer platform
× Requires developer to apply fixes
× No VPAT generation

Pricing: $29/mo (1 site), $79/mo (5 sites), $199/mo (25 sites)

Verdict: Best value for agencies. 25 sites for $199/month with AI-generated code fixes means you can scan and remediate client sites at scale without per-domain pricing eating your margins.

Siteimprove

Enterprise website quality platform with accessibility as one module. Comprehensive dashboards and reporting.

Pros

✓ Comprehensive website quality analytics
✓ Strong accessibility dashboards and reporting
✓ WCAG 2.1 AA and AAA scanning
✓ Established platform with enterprise track record

Cons

× Multi-site pricing typically $2,000+/month
× Annual contracts required
× No AI-generated code fixes
× Overkill if you only need accessibility

Pricing: $500+/mo (single site), custom pricing for multi-site

Verdict: Most feature-rich platform for agencies that need accessibility, SEO, and content quality analysis in one tool. Price is the barrier — multi-site typically runs $2,000+/month.

AudioEye

Hybrid accessibility platform with automated scanning and human auditors. Per-domain pricing.

Pros

✓ Human accessibility auditors
✓ VPAT generation for client procurement needs
✓ Managed remediation reduces agency workload
✓ Comprehensive compliance documentation

Cons

× Per-domain pricing at $199+/site adds up fast
× 10 client sites = $1,990+/month
× Annual contracts typical
× Overlay component included

Pricing: $199+/domain/mo

Verdict: Strong compliance documentation and VPAT generation, but per-domain pricing makes it expensive for agencies managing more than a handful of client sites.

axe Monitor

Deque's enterprise accessibility monitoring platform. Continuous scanning with dashboards and alerting.

Pros

✓ Continuous automated scanning
✓ Built on the axe-core engine
✓ Dashboards and trend tracking
✓ Integrates with axe DevTools for developer workflows

Cons

× Custom/enterprise pricing, not transparent
× Per-domain pricing model
× No AI-generated code fixes
× Requires sales conversation to get pricing

Pricing: Custom pricing (typically $300+/mo per domain)

Verdict: Solid continuous monitoring for agencies that want ongoing scanning. Custom pricing makes it hard to predict costs, and per-domain pricing limits scalability.

UserWay

Overlay widget with multi-site plans available. Quick deployment across client sites.

Pros

✓ Fast deployment — script tag per client site
✓ No developer needed for installation
✓ Volume discounts for agencies
✓ Free widget tier available

Cons

× Overlay does not fix source code
× Limited compliance documentation
× Per-site pricing without bundled plans
× Not a substitute for real accessibility testing

Pricing: $49-$199/mo per site (volume discounts available)

Verdict: Easiest to deploy across multiple client sites, but overlay approach does not fix source code. Useful as a quick add-on, not as a compliance strategy.

Why Multi-Site Pricing Matters

Most accessibility tools charge per domain. For an agency managing 10-25 client sites, per-domain pricing turns a reasonable tool cost into a significant line item.

At $199 per domain per month, scanning 25 client sites with AudioEye costs $4,975/month. Siteimprove’s multi-site pricing is custom but typically runs even higher. A11yProof’s Agency plan covers 25 sites for $199/month total.

The pricing model determines whether accessibility scanning is a profit center or a cost center for your agency. At under $8 per client site per month, you can build accessibility auditing into every client engagement without eroding margins.

Scanning Depth vs Deployment Speed

Agencies face a tension between thoroughness and efficiency. You need tools that produce meaningful results without requiring hours of setup per client site.

A11yProof and Siteimprove scan sites automatically once configured. axe Monitor runs continuous scans with alerting. These tools let you add a client site and get results without manual page-by-page testing.

UserWay and similar overlay tools deploy in minutes but do not actually test for WCAG compliance. They add a widget without examining the underlying issues. For agencies selling accessibility as a service, deploying an overlay without identifying real issues is a liability.

Client Reporting

Agencies need reports that communicate findings to non-technical stakeholders. A compliance report showing “47 WCAG 2.1 AA violations found, 38 fixed, 9 in progress” tells a client exactly where they stand.

A11yProof generates criterion-level reports per site. Siteimprove has the strongest dashboards with trend tracking. AudioEye includes VPAT generation for clients with procurement requirements. axe Monitor provides developer-oriented reporting that may need translation for non-technical clients.

Building an Accessibility Practice

The right tool enables a repeatable service offering. Scan client sites monthly, remediate new issues, deliver compliance reports, and charge accordingly. We built A11yProof’s Agency plan to make this model financially viable at scale.

Q&A

What is the most cost-effective accessibility tool for agencies?

A11yProof's Agency plan at $199/month for 25 sites is the most cost-effective option at under $8 per client site per month. Siteimprove's multi-site pricing starts around $2,000/month. AudioEye charges $199+ per domain. For agencies managing 10+ client sites, the pricing difference is significant.

Q&A

Should agencies use overlay tools for client accessibility?

As a standalone solution, no. Overlay tools do not fix source code issues and face legal scrutiny. Agencies that deploy overlays without fixing underlying issues are creating liability for their clients. Use scanning tools that identify and fix real WCAG violations. The overlay can be a supplement but not a substitute.

Q&A

How many sites can each tool handle efficiently?

A11yProof's Agency plan covers 25 sites at $199/month with no per-domain fees. Siteimprove and AudioEye use per-domain pricing that scales linearly. axe Monitor uses custom pricing. For agencies managing 10+ sites, bundled pricing is critical to maintaining margins on accessibility services.

How should agencies price accessibility services to clients?

Most agencies charge accessibility auditing as a separate line item, typically $500-$2,000 per audit depending on site complexity. With a tool like A11yProof at $199/month for 25 sites, your per-client tool cost is under $8/month, leaving significant margin for audit and remediation services. The tool cost should be a fraction of what you charge clients.

Should agencies use the same accessibility tool for all client sites?

Yes, if possible. Consistent tooling means your team learns one workflow, reporting is standardized across clients, and you can identify patterns across sites. Multi-site plans from A11yProof and Siteimprove are designed for this use case.

Do agency clients care about WCAG compliance?

Increasingly, yes. ADA lawsuits targeting websites have grown year over year. Enterprise clients may require accessibility compliance as part of their vendor agreements. Proactively offering accessibility auditing positions your agency as thorough and reduces client legal risk.

Can agencies white-label accessibility reports?

Siteimprove and AudioEye offer white-label or custom-branded reporting on enterprise plans. A11yProof and axe Monitor do not currently offer white-label reports. For most client relationships, clearly attributed reports from a recognized accessibility tool carry more weight than white-labeled ones.
