Most web design agencies do not have an accessibility auditor on staff. When a client needs WCAG 2.2 AA conformance verified, the agency subcontracts the work to a specialist. This is standard practice across the industry, and it creates a steady pipeline of project work for independent auditors and small accessibility consultancies.
Understanding how agencies subcontract accessibility audits gives you an advantage whether you are a freelancer looking for contract work or an agency evaluating how to bring accessibility services to your clients.

Why Do Web Design Agencies Subcontract Audits?
A manual accessibility audit requires deep familiarity with WCAG success criteria, assistive technology, and how code behavior affects real users. That expertise takes years to develop. Most agency teams are built around design, development, and project management.
Hiring a full-time auditor only makes sense if the agency has a consistent volume of accessibility projects. For most mid-size agencies, subcontracting is the more practical path. They bring in a qualified auditor per project, pay for the deliverable, and pass the cost along to the client with a markup.
How the Subcontracting Relationship Works
The typical arrangement follows a predictable pattern. A client asks the agency about ADA compliance or WCAG conformance. The agency reaches out to an auditor or accessibility consultant they have an existing relationship with, gets a quote based on scope, and includes the audit in a broader project proposal.
Once the project kicks off, the auditor receives access to the digital asset, conducts the evaluation against the agreed standard (usually WCAG 2.1 AA or WCAG 2.2 AA), and delivers the report. In white label arrangements, the report carries the agency’s branding. The client may never know a subcontractor was involved.
Some agencies prefer a referral model instead. They introduce the client directly to the auditor and collect a referral fee. This avoids the agency managing deliverables outside their expertise, though it means less control over the client relationship.
White Label vs. Referral: Which Model Agencies Prefer
White labeling is the dominant model. Agencies want to present a complete service offering without revealing the supply chain behind it. The client sees one vendor, one invoice, one point of contact.
For the auditor, white label work means steady volume but less brand visibility. Your name does not appear on the report. You build the relationship with the agency, not the end client.
Referral arrangements preserve your brand. You work directly with the client, deliver under your own name, and the agency receives a percentage or flat fee. This works well for auditors who are building their own client base and want the exposure.
Both models are common. The right choice depends on whether you prioritize volume or visibility.
What Agencies Look for in an Audit Partner
Agencies care about three things when selecting a subcontractor for accessibility work: turnaround time that fits their project timeline, clear and actionable audit reports their developers can work from, and consistent communication and availability for follow-up questions.
Credentials matter, but reliability matters more. An agency that has been burned by a missed deadline or a vague report will not use that auditor again. Certifications like DHS Trusted Tester or CPACC signal competence, but the quality of your deliverable and your responsiveness are what keep the relationship going.
Pricing is a factor but rarely the deciding one. Agencies already plan to mark up the cost. They need the audit to be defensible and thorough, not the cheapest option available.
How Auditors Price Subcontract Work
Pricing for subcontract audits follows the same structure as direct-to-client work: per page or per screen, with complexity adjustments. A 15-page informational website costs less than a web app with dynamic forms, authentication flows, and interactive components.
Some auditors offer agencies a discounted rate in exchange for volume commitments. If an agency sends five projects a quarter, a 10% to 15% discount on each is reasonable. Others keep pricing consistent regardless of volume, which is also a valid approach.
The agency then marks up the cost to the end client. Markups of 30% to 100% are standard. A $3,000 audit might appear on the client invoice as $4,500 to $6,000, bundled into a broader compliance or remediation package.
How to Position Yourself for Agency Subcontract Work
If you are a freelance auditor or run a small accessibility consulting firm, agency partnerships can become a significant revenue stream. Build a portfolio with sample audit report excerpts (redacted for confidentiality) that demonstrate the clarity and depth of your work. List your services and relevant credentials in professional directories where agencies search for partners. Reach out to agencies directly with a short pitch explaining what you deliver, your turnaround, and your pricing structure. Offer a trial engagement at standard pricing so the agency can evaluate your work before committing to ongoing volume.
Agencies want to remove risk from their accessibility offerings. Making it easy for them to say yes is the fastest way into their workflow.
What About Remediation and Ongoing Work?
An audit is often the starting point of a longer engagement. Once the report identifies accessibility issues, someone needs to fix them. Some agencies have developers who can address remediation internally. Others subcontract that work too.
Auditors who also offer remediation guidance or can collaborate with agency developers during the fix cycle become more valuable partners. The ability to validate fixes after remediation, confirming that each issue now conforms to the relevant WCAG success criteria, adds another billable phase to the relationship.
For agencies pursuing ADA compliance projects, the full cycle from audit to remediation to conformance documentation represents a complete service line. Subcontractors who can support multiple phases of that cycle are harder to replace.
Do agencies need auditors who specialize in specific platforms?
Some agencies focus on Shopify, WordPress, or custom web apps. An auditor with experience evaluating that specific platform can work faster and deliver more precise remediation guidance. Platform-specific experience is a differentiator, not a requirement. WCAG conformance evaluation applies universally, but knowing the common issues in a particular CMS or ecommerce platform saves the agency time during the fix cycle.
Can automated scans replace a subcontracted audit?
No. Scans only flag approximately 25% of issues. They are useful for ongoing monitoring and catching regressions, but they cannot determine WCAG conformance. A manual accessibility audit conducted by a qualified auditor is the only way to confirm conformance. Agencies that try to substitute a scan for an audit are exposing their clients to legal and compliance risk.
How do I set pricing for white label audit work?
Price based on scope and complexity, the same way you would for a direct client. If you offer a volume discount to agencies, keep it modest. Your expertise has the same value whether the end client sees your name or not. A 10% to 15% discount for consistent volume is reasonable. Going lower erodes your margins without meaningful benefit.
Agencies subcontract accessibility audits because the work requires expertise their teams do not carry. For qualified auditors, this creates a reliable channel of project work built on professional partnerships.
