What this business actually is
A web accessibility consulting business helps organizations make their websites and apps usable by people with disabilities and compliant with standards like the Web Content Accessibility Guidelines (WCAG 2.1/2.2 AA) and the Americans with Disabilities Act (ADA). The work falls into three buckets: auditing a site for accessibility barriers, remediating the code and content to fix those barriers, and ongoing retainers to keep sites compliant as they change. Demand is largely driven by legal risk — thousands of ADA web-accessibility lawsuits and demand letters are filed in the US each year — plus procurement requirements (Section 508 for government vendors) and a genuine ethical push from larger brands.
What you actually do — the daily reality
A typical week mixes deep, focused testing with client communication. Auditing means running automated scanners (axe, WAVE, Lighthouse) to catch the easy issues, then doing the manual work that actually matters: navigating the entire site with only a keyboard, running it through screen readers like NVDA, JAWS, and VoiceOver, checking color contrast, inspecting ARIA and semantic HTML, and testing forms and dynamic components. You document each issue with the WCAG success criterion it violates, severity, and a concrete code-level fix, usually in a spreadsheet or a tool like a structured report. Remediation work is straight front-end development. The rest of the time is writing reports, walking developers through fixes, and explaining to non-technical clients why an overlay widget is not a real solution.

Real earnings — an honest breakdown
Not best-case fantasies. Here is what beginners, experienced operators, and the top earners actually report — and what it took to get there.
Most people start while still employed and take on one or two clients. A focused audit of a small-to-medium marketing site commonly bills $1,500 to $6,000. In year one, part-timers realistically report $2,000 to $5,000 per month; those who go full-time and can sell typically reach $4,000 to $9,000 per month once a pipeline forms.
Consultants with a few years, a certification, and case studies commonly bill $100 to $200 per hour or fixed project fees, landing $8,000 to $18,000 per month solo. Remediation contracts and recurring monitoring retainers ($500 to $3,000 per month per client) add the stability that one-off audits lack.
Top independent consultants and small accessibility studios bill enterprise audits at $15,000 to $60,000+ each and gross $250,000 to $700,000+ per year, but reaching that means a team of testers and developers, deep VPAT/Section 508 expertise, and enterprise relationships — it is a different business from solo consulting, and most people stay solo by choice.
Effective billable rate runs $75 to $200 per hour for experienced consultants. Counting unbilled selling, report writing, and admin, realistic blended rates are often $60 to $130 per hour, higher once you have repeatable templates.
Whether you can actually do manual testing and remediation (not just run a scanner), having a recognized certification or named clients to build trust, and whether you sell recurring retainers instead of living job-to-job on one-off audits.
How to actually start — step by step
- Month 1
Get genuinely competent at manual testing — keyboard-only navigation, NVDA/VoiceOver, and reading WCAG 2.2 success criteria. Audit 3 to 5 real websites for free or for friends and write full reports. You cannot fake this; the skill is the product.
- Month 2
Build credibility. Study for and ideally sit the IAAP CPACC (foundational) or WAS (technical) exam, publish 1 to 2 detailed before/after case studies, and create reusable report and VPAT templates so each audit is faster than the last.
- Months 2-3
Land first paid work by targeting agencies that build sites but lack accessibility expertise, plus small businesses that received an ADA demand letter. Price your first audits at the low end of the range to build references, but never so low that you teach yourself the work is worthless.
- Days 90+
Convert audits into remediation projects and monthly monitoring retainers. Recurring revenue is what turns this from feast-or-famine project work into a stable consulting business.
- Ongoing
Stay current. WCAG versions, ARIA patterns, and case law evolve, and the European Accessibility Act and updated ADA Title II rules keep expanding demand — staying credible requires real continuing education.
What skills you actually need
Skills you must have before starting
- Solid HTML, CSS, and the ability to read and reason about JavaScript and ARIA
- Real working knowledge of WCAG success criteria, not just awareness that they exist
- Competence with screen readers and keyboard-only testing — the manual skills automated tools cannot replace
Skills you can learn as you go
- Writing clear, prioritized audit reports that developers can actually act on
- VPAT/ACR documentation and Section 508 conformance for government-adjacent clients
- Scoping and pricing projects so you do not undercount the manual testing hours
What separates average operators from high earners
- Being able to remediate, not just identify — clients pay far more for someone who fixes the code than someone who only hands over a list
- Translating technical findings into legal and business risk that non-technical decision-makers understand
- Building retainer relationships and a referral network with agencies and law firms rather than chasing one-off audits
What most people get wrong
The common mistakes, the reasons people quit, and the things nobody warns you about.
- Relying only on automated scanners, which catch roughly a third of issues — selling a 'scan' as a real audit destroys your credibility the first time a client gets sued anyway
- Recommending accessibility overlay widgets as a fix; the disability community and many courts view them as ineffective, and serious clients will not trust you if you push them
- Guaranteeing 'ADA compliance' or 'lawsuit-proof' results — accessibility is ongoing conformance to WCAG, and overpromising legal outcomes invites liability you are not qualified to carry
- Underestimating how long thorough manual testing of a real site takes, then losing money on fixed-fee audits
- Writing reports developers cannot use — vague findings with no code examples or WCAG references get ignored
- Never moving past one-off audits into remediation and retainers, leaving income lumpy and stressful
Tools and equipment you need
What to buy cheap, where to invest, and what you can rent or borrow at first.
- Screen readers (NVDA, JAWS, VoiceOver, TalkBack) Free – $1,000
NVDA and VoiceOver are free; a JAWS license matters for thorough cross-screen-reader testing.
- axe DevTools / WAVE / Lighthouse Free – $800
Automated triage tools. Useful for the easy 30%, never the whole job.
- Color contrast analyzers Free – $0
Free tools like TPGi Colour Contrast Analyser cover this.
- Multiple browsers and devices Free – $800
Real testing requires Chrome, Firefox, Safari, plus iOS and Android for mobile screen readers.
- Report and VPAT templates Free – $0
Build your own once; they compound your speed on every project.
- Code editor and local dev environment Free – $0
Needed for remediation work; standard developer tooling you likely already own.
How to find customers
What actually works:
- Partnering with web design and development agencies that build sites but have no in-house accessibility expertise — they refer clients or white-label your audits
- Reaching out to organizations that just received an ADA demand letter or lawsuit, where the need is urgent and budget appears fast
- Targeting sectors with mandates: government vendors (Section 508), higher education, healthcare, and finance
- Publishing detailed accessibility content and case studies that rank and demonstrate genuine expertise
- Networking in accessibility communities (A11y Slack, conferences, IAAP) where referrals and subcontracting flow
- Connecting with disability-rights and ADA-focused law firms who refer remediation work to defendants
Where your customers are: Mid-sized companies, agencies, government contractors, universities, and any business with legal exposure or procurement requirements. Demand spikes when a company receives a demand letter, fails a procurement review, or redesigns its site.
How long it takes to build a client base: Because sales cycles are slower and trust-driven, expect one to three months to land your first real client and six to twelve months to build a steady pipeline, faster if you arrive with a certification and case studies.
What is usually a waste of time: Cold mass-emailing tiny businesses with no legal exposure, and competing with $99 overlay vendors on price. Early on, one credible case study and an agency partnership outperform broad outreach.
How this business scales
Can you grow it to full-time? Yes. The combination of legal-risk-driven demand, high billable rates, and retainer revenue means a competent solo consultant can reach a strong full-time income, often within the first year if they can sell.
Can you hire people and step back? Possible. You can hire testers and remediation developers and move into scoping, sales, and QA, but accessibility quality is hard to delegate — a bad audit damages your reputation — so hiring requires careful training and review.
Can you sell it one day? Boutique accessibility firms with enterprise contracts, recurring retainers, and a brand do get acquired, often by larger digital agencies or compliance companies. A pure solo practice is harder to sell because the expertise is you.
What scaling actually requires: Standardized testing processes, trained staff who maintain quality, recurring monitoring contracts, and enterprise relationships. The hard part is keeping audit quality consistent as you add people.
Is this right for you? An honest checklist
A strong fit if…
- You have or can build real front-end and WCAG skills and enjoy meticulous, detail-heavy work
- You want a high-value, defensible niche rather than competing as a generalist developer
- You are comfortable being the expert who explains uncomfortable truths to clients
- You like recurring, relationship-based work over constant cold selling
A poor fit if…
- You want a fully passive or non-technical business
- You are not willing to learn screen readers and do tedious manual testing properly
- You would be tempted to oversell scans or overlays you know are inadequate
- You need fast, predictable income from week one
Before you start, ask yourself…
- Can I actually navigate and fix a complex site with a keyboard and screen reader, or do I only know the theory?
- Am I comfortable being responsible for advice that has legal and reputational weight for my clients?
- Will I build retainers and remediation work, or am I just chasing one-off audits?
Frequently asked questions
Do I need to be a developer to start a web accessibility business?
For audits, you need to read and reason about HTML, CSS, ARIA, and JavaScript and understand WCAG deeply, even if you are not building from scratch. For remediation you need real front-end coding skills. People from QA or UX backgrounds can do auditing well, but the higher-paying remediation work requires development ability.
Is a certification like IAAP CPACC or WAS necessary?
It is not legally required, but in a trust-driven, legally-sensitive field it meaningfully helps you win work, especially with larger clients and agencies. CPACC covers foundational knowledge; WAS is the technical credential. Many successful consultants get one within their first year to build credibility.
Can I just sell automated scans?
No, not honestly. Automated tools catch roughly 30 to 40 percent of accessibility issues and miss most of what causes real barriers and lawsuits. Selling a scan as a full audit is both misleading and risky for the client. Manual testing with screen readers and keyboards is the core of legitimate work.
What about accessibility overlay widgets — should I recommend them?
Most accessibility professionals and the disability community strongly oppose overlays, and they have been named in lawsuits rather than preventing them. Recommending them will damage your credibility with serious clients. The honest path is fixing the underlying code and content.
How much can I charge for an audit?
Small marketing-site audits commonly run $1,500 to $6,000, and enterprise audits run far higher. Pricing depends on the number of unique page templates and components, not raw page count. The most common pricing mistake is undercounting the manual testing hours.
Is demand actually growing?
Yes. US ADA web-accessibility lawsuits and demand letters number in the thousands per year, updated ADA Title II rules now cover state and local government sites, and the European Accessibility Act expands obligations for companies selling into the EU. The legal and procurement drivers are real and increasing.
Can I do this part-time while employed?
Yes, and many people start exactly this way, taking on one or two audits around a job. Just check your employment agreement for conflicts, since accessibility work can overlap with web-development employers, and be realistic that thorough audits take real focused hours.
Should I guarantee my clients will not get sued?
No. Accessibility is ongoing conformance to a standard, not a permanent legal shield, and sites change constantly. Promise rigorous WCAG-based work and clear documentation, not lawsuit immunity. Overpromising legal outcomes creates liability you are not positioned to carry.
