Web agencies are increasingly fielding client requests for digital accessibility services. Whether a client needs a Web Content Accessibility Guidelines (WCAG) audit, an Accessibility Conformance Report (ACR), or ongoing remediation support, the demand is real. The problem is that most web agencies do not have trained accessibility auditors on staff. The good news: they do not need to. Subcontracting accessibility audits and Voluntary Product Accessibility Template (VPAT) services to a qualified provider is a proven, efficient path for agencies that want to expand their service offerings without overextending their teams.
Why Client Demand for Accessibility Services Is Growing
Several forces are driving accessibility demand. ADA website compliance lawsuits continue at a high pace, with thousands of federal filings each year targeting businesses across industries. Title II of the ADA now includes a published rule requiring WCAG 2.1 AA conformance for state and local government web content. Section 508 procurement requirements remain in effect for federal agencies and their vendors. The European Accessibility Act (EAA) is bringing new obligations for organizations serving EU markets. And enterprise procurement teams are routinely requesting VPATs and ACRs before approving software purchases.
For web agencies, this means clients are asking about accessibility more often. They want to know if their website is compliant, what an audit involves, whether they need a VPAT, and how to fix issues. When an agency cannot answer those questions or deliver those services, clients look elsewhere. Subcontracting allows an agency to say yes to every accessibility request while maintaining quality and protecting its reputation.
| Client Need | Service an Agency Can Subcontract |
|---|---|
| Website is being sued or received a demand letter | WCAG 2.1 AA audit, remediation guidance, user evaluation |
| Enterprise client requesting a VPAT | Audit plus ACR completion (VPAT services) |
| Government contract requires Section 508 conformance | Audit against WCAG standard with formal ACR |
| Client wants to reduce legal risk proactively | Audit, remediation, validation, accessibility statement |
| Mobile app or web app needs evaluation | App-specific WCAG audit across applicable environments |
What to Look for in a Subcontract Accessibility Partner
Not all accessibility providers are equal, and choosing the wrong partner can damage an agency’s credibility. The most important factor is that the provider conducts fully manual audits. Automated scans detect approximately 25% of accessibility issues. A scan is not an audit. An audit involves a human evaluator systematically reviewing each page or screen against every applicable WCAG success criterion. Any provider that positions automated scan results as an audit deliverable is not a credible subcontractor.
Beyond the audit methodology, agencies should look for providers that offer transparent pricing, clear turnaround times, and detailed audit reports that developers can act on. The audit report should include specific issue descriptions, the relevant WCAG success criteria, severity ratings, screenshots or code references, and remediation recommendations. If a provider delivers vague or surface-level reports, the agency’s development team will struggle to make the necessary fixes.
For VPAT services, the provider should understand the difference between a VPAT and an ACR. The VPAT is the blank template. The ACR is the completed document that reflects the current conformance state of a product. A credible provider will conduct an audit first and then populate the ACR based on findings. Any provider willing to fill in a VPAT without performing an audit is producing a document that has no real foundation.
Agencies should also confirm whether the provider offers white-label or partnership arrangements. Some accessibility companies allow agencies to deliver audit reports and ACRs under the agency’s brand, or at minimum, the agency can serve as the primary point of contact with the client while the subcontractor handles the technical evaluation work behind the scenes.
How Subcontracting Typically Works
The subcontracting workflow is simpler than most agencies expect. It begins with the agency gathering basic information from the client: the URLs or product details that need evaluation, the target WCAG standard (typically WCAG 2.1 AA or WCAG 2.2 AA), the number of pages or screens, and whether a VPAT or ACR is also needed. The agency passes this information to the accessibility partner, who provides a quote and timeline.
Once the engagement is approved, the accessibility partner conducts the audit. This is a fully manual evaluation that typically covers a representative sample of pages or screens, examining every applicable success criterion. The deliverable is a detailed audit report, and if VPAT services are included, a completed ACR.
After the audit report is delivered, the agency’s development team begins remediation. This is where the agency adds significant value: its developers already know the client’s codebase, content management system, and design requirements. They are in the strongest position to implement fixes efficiently. If the agency’s team needs guidance on specific issues, a good accessibility partner will provide support or clarification.
Following remediation, a validation step confirms that issues have been properly addressed. The accessibility partner can re-evaluate the pages or screens that had issues to verify fixes. Some agencies also request user evaluation, where individuals with disabilities use assistive technology such as screen readers to evaluate the product. This adds a layer of real-world evidence that the product is accessible and can serve as strong legal documentation.
The Financial Upside for Agencies
Subcontracting accessibility work is not a cost center for agencies. It is a revenue opportunity. Agencies can mark up audit and VPAT services, bundle them with their existing design, development, and maintenance packages, and position accessibility as a value-added service tier. Clients increasingly expect their agency to have an accessibility answer, and the agencies that do will retain more clients and win more contracts.
The alternative is hiring a full-time accessibility specialist, which involves recruiting from a relatively small talent pool, paying a competitive salary, investing in ongoing training, and still potentially lacking the breadth of expertise needed to cover WCAG audits, VPAT completion, user evaluation, and remediation consulting. Subcontracting eliminates these overhead costs entirely while still giving the agency a credible, professional service to offer.
Government and enterprise clients are especially valuable in this regard. Public sector organizations operating under ADA Title II or Section 508 requirements need ongoing compliance support, not a one-time project. When an agency can deliver audits, ACRs, remediation, and monitoring through a subcontracted partner, it creates a recurring revenue stream that strengthens the client relationship over time.
Common Mistakes Agencies Make When Entering Accessibility
One of the most frequent errors is relying on automated scan tools and presenting those results as a complete accessibility evaluation. Scans are useful for identifying certain categories of issues quickly, but they cover only about 25% of what a full WCAG audit addresses. Agencies that present scan results as audit deliverables risk losing credibility, especially with informed clients who understand the difference.
Another mistake is underpricing the service. Accessibility audits require significant time and expertise. A thorough evaluation of a medium-sized website against WCAG 2.1 AA can involve many hours of skilled human work. Agencies that quote unrealistically low prices either end up absorbing costs or delivering inadequate results. Understanding the real cost of audit services from a subcontract partner helps agencies set appropriate client pricing.
Some agencies also make the mistake of treating accessibility as a one-time fix. Websites change constantly through content updates, new features, design refreshes, and third-party integrations. Each change can introduce new accessibility issues. Agencies that frame accessibility as an ongoing service rather than a single project build more sustainable revenue and deliver better outcomes for clients.
Finally, agencies sometimes fail to communicate the scope of what accessibility involves. A client may assume a quick scan is sufficient, and if the agency does not educate them otherwise, the client may end up with a false sense of compliance. Agencies have a responsibility to explain why audits must be thorough, why scans alone are not enough, and what the real path to conformance looks like.
Frequently Asked Questions
Can a web agency offer accessibility audits without having an auditor on staff?
Yes. Agencies routinely subcontract specialized services. By partnering with a qualified accessibility provider that conducts fully manual WCAG audits, an agency can deliver professional audit reports and ACRs to clients without hiring an in-house auditor. The agency manages the client relationship while the subcontractor performs the evaluation work.
What is the difference between a VPAT and an ACR?
A VPAT (Voluntary Product Accessibility Template) is the blank template document. An ACR (Accessibility Conformance Report) is the completed version of that template, filled in based on an actual audit of a product. When a client says they need a VPAT, they typically mean they need a completed ACR that documents the accessibility conformance state of their product.
How long does it take to get an audit and ACR through a subcontracted provider?
Timelines vary based on the size and complexity of the product being evaluated. A standard website audit may take one to three weeks depending on the number of pages or screens in scope. ACR completion adds additional time after the audit is finished. Agencies should discuss turnaround expectations upfront with their accessibility partner to set accurate client timelines.
Do agencies need to disclose that they subcontract accessibility work?
This depends on the agency’s client agreements and the nature of the partnership. Many agencies subcontract specialized work across various disciplines without explicit disclosure, as it is standard practice. However, if a client specifically asks who performs the audit, transparency is always the right approach. Some accessibility providers offer white-label arrangements that allow the agency to present services under its own brand.
Is an automated scan sufficient for a client who needs a VPAT?
No. A VPAT must be populated based on a thorough audit that evaluates the product against all applicable WCAG success criteria. Automated scans detect approximately 25% of accessibility issues. An ACR based only on scan results would be incomplete and potentially misleading to procurement reviewers who rely on ACRs to make purchasing decisions.
