Vetting an accessibility consultant before signing a contract means verifying three things: their technical credentials, the quality of their past deliverables, and how they actually work with clients. Ask for a sample audit report, confirm they conduct manual evaluations against WCAG 2.1 AA or WCAG 2.2 AA, review their experience with your asset type (website, web app, mobile app, or software), and confirm pricing in writing. A qualified consultant answers direct questions with direct answers. If anything feels vague, slow down before signing.
The wrong hire costs months of wasted work and leaves you exposed to ADA risk. The right hire saves both.
| Area | What to Confirm |
|---|---|
| Credentials | Certifications like CPACC, WAS, or DHS Trusted Tester. Years of hands-on auditing. |
| Sample Work | A redacted audit report from a real project showing issue detail, location, and remediation guidance. |
| Methodology | Fully manual evaluation against a stated WCAG standard, not scan-only. |
| Scope Fit | Direct experience with your asset type and industry. |
| Pricing | Written quote with deliverables, timeline, and what is excluded. |
| Communication | Clear answers, named point of contact, defined response times. |
Start With Credentials, Not Marketing Copy
A consultant’s website tells you what they want you to think. Credentials tell you what they have actually done.
Look for recognized certifications: CPACC and WAS from the IAAP, or DHS Trusted Tester for federal work. These are not the only markers of skill, but they confirm the person has passed a knowledge bar. Years of hands-on auditing matter more than years in the industry. Ask how many audits they have personally conducted in the last twelve months.
If a consultant cannot name a specific certification or describe their auditing process in detail, that is a signal.
What Should You Ask for as a Sample?
Ask for a redacted audit report from a real project. Not a marketing PDF. Not a template. An actual deliverable with client identifiers removed.
A good audit report identifies each issue, names the WCAG criterion it relates to, shows where the issue lives on the page or screen, and gives the developer enough context to fix it. If the sample is a list of scan output dressed up with branding, that is not an audit.
This single document tells you more than any sales call.
Confirm the Methodology Is Manual
Scans flag approximately 25% of issues. A consultant who relies on automated checkers alone cannot determine WCAG conformance for your asset. Ask directly: “Is your evaluation fully manual?” The answer should be yes.
If they describe a hybrid approach, ask what percentage of the work is conducted by a person reviewing code, content, and interaction patterns. The honest answer is most of it. Scans assist but do not replace human evaluation.
Match the Consultant to Your Asset Type
A consultant who audits informational websites may not be the right fit for a complex SaaS web app. Mobile app auditing requires familiarity with iOS and Android accessibility APIs. Ecommerce on Shopify has its own patterns. EdTech and LMS products carry specific considerations.
Ask for two or three project examples that mirror your asset type and industry. Generic experience is not the same as relevant experience.
What Should Be in the Written Quote?
Before signing, get pricing in writing with these items spelled out:
Scope: The exact pages, screens, or flows being evaluated.
Standard: WCAG 2.1 AA or WCAG 2.2 AA, and which environments (desktop, mobile, both).
Deliverables: Audit report format, ACR if applicable, remediation guidance.
Timeline: Start date, draft delivery, and final delivery.
Exclusions: What is not included (e.g., remediation work, validation rounds).
Revalidation: Whether re-evaluation after fixes is part of the engagement or billed separately.
Verbal estimates are not a contract. Anything not in writing is not real.
Red Flags Before You Sign
Certain patterns reliably predict a bad engagement. Watch for these:
Guarantees of “100% ADA compliance” or “lawsuit-proof” status are a warning sign. Pricing that seems significantly below market without a clear reason should raise questions. Refusal to share a sample report or client references is concerning. Heavy reliance on automated tools described as the primary audit method signals a weak process. Vague answers about who specifically will conduct the work suggest a lack of accountability. No defined process for questions during remediation means you will be left guessing.
Any one of these is reason to pause. Two or more is reason to walk.
How to Complete the Final Comparison
Once you have two or three vetted candidates, compare them side by side on the same criteria: methodology, deliverables, timeline, price, and fit. Price alone is misleading. A cheaper audit that produces a thin report costs more in the long run because your team cannot act on it.
The consultant who answers questions clearly, shows real work, and writes a precise quote is the one to hire.
How long should the vetting process take?
Plan on two to three weeks from first contact to signed contract. That gives time for an intro call, sample review, written quote, and reference check without rushing the decision.
Do I need an accessibility consultant if I already have a developer?
Yes. Developers build. Auditors evaluate. The two roles require different training and a different lens. A developer auditing their own work has a built-in blind spot.
What is the difference between an accessibility consultant and an auditor?
An auditor conducts the evaluation and produces the report. A consultant may conduct audits, but the role often extends into strategy, training, remediation guidance, and ongoing advisory work. Many practitioners do both. Confirm which role you actually need before hiring.
Should I ask for references?
Ask for two client references and call them. A ten minute conversation with a past client reveals what no proposal can: how the consultant communicates under pressure, how accurate their estimates were, and whether the deliverable held up.
Vetting takes time. Signing the wrong contract takes longer to recover from.
