How to Choose a Website Accessibility Vendor

The market is crowded with overlays and box-checkers. Here is how to tell a real compliance partner from a risky one before you sign.

The Short Answer

Choose a vendor that tests manually against WCAG, fixes issues in your source code including your PDFs, proves the fixes with re-testing and documentation, and can support you after the deadline. Walk away from anyone selling an overlay or promising guaranteed, instant compliance. For a government site, weigh public-sector experience and a defensible, documented process above price.

Why the Choice Matters

Accessibility is a field where the wrong vendor can leave you worse off than doing nothing, because you have paid for a false sense of security. A widget that promises compliance, an automated-only scan sold as an audit, or a vendor that ignores your documents will each leave real barriers in place and no defensible record. The criteria below are how you separate marketing from a partner that actually gets you compliant.

What to Look For, and the Red Flags

Criterion	What to Look For	Red Flag
Testing method	Manual testing by specialists using assistive technology, plus automated tooling for scale	Automated scan only, sold as a full audit
Remediation	Fixes made in your source code that persist through updates	An overlay or surface-level patch
Documents	PDFs and forms remediated directly, tags and reading order fixed	Documents ignored or out of scope
Proof of work	Each fix re-tested against the criterion it failed, with documentation	Trust us, no re-testing or record
Credentials	Certified specialists, including testers who use assistive technology daily	No credentials, no named testers
Public-sector experience	Knows Title Il, procurement, and government platforms	Generic commercial experience only
Ongoing support	A monitoring program to stay compliant after the fix	One-and-done, no path to maintain
Guarantees	Honest framing about reducing risk	Guaranteed compliant or lawsuit-proof

Questions to Ask on the Call

A few direct questions will tell you most of what you need to know.

Do you test manually with assistive technology, or run an automated scan?
Who does the testing, and what are their credentials?
Do you remediate our PDFs and documents?
And what happens after we are compliant?
How do you prove each issue is fixed?

The answers separate a real partner from a reseller quickly.

Red Flags That Should End the Conversation

Some answers should stop the process.

A vendor selling an overlay or widget as compliance.

A promise of quaranteed compliance or immunity from lawsuits.

An automated-only scan presented as an audit.

A refusal to include your documents.

No ability to re-test and document the fixes.

In 2025 the FTC fined the overlay vendor accessible $1 million for exactly the kind of claim you should be wary of.

Frequently Asked Questions

Should we just pick the cheapest bid?

Price matters, but the cheapest option is often an overlay or an automated scan that leaves you non-compliant. Compare on method and proof first, then price.

Are certifications required?

They are not legally required, but certified specialists and testers who use assistive technology are strong signals that the work will hold up.

Is a big national firm better than a specialist?

Not necessarily. Public-sector experience and a documented, manual process matter more than size. Ask about work with governments specifically.

Can any web developer do this?

A good developer can implement fixes, but reaching and proving WCAG conformance takes accessibility expertise and assistive-technology testing on top of development.
