An accessible website works for people who use screen readers, keyboards, screen magnifiers or voice control. The usual benchmark is the Web Content Accessibility Guidelines (WCAG) at level AA, the level most accessibility laws reference. Each of the six agencies below publishes accessibility work on its own website.
How to choose
When the site is due for a rebuild
Isadora Agency and Credera both show redesigns where page structure and navigation were reworked to meet accessibility standards.
When many products share one standard
HCLTech and Cognizant sell assessment programs that hold a whole portfolio of digital products to one set of WCAG criteria, with reports that rank issues by priority.
When a law sets the deadline
Netcentric publishes a preparation guide for the European Accessibility Act and runs audits and design system work for clients getting ready for it.
When testing has to keep pace with releases
Virtusa automates accessibility checks inside the release cycle.
Testing firms and build teams do different parts of the job
HCLTech and Cognizant concentrate on finding issues and reporting them against WCAG. Virtusa builds the same kind of checks into automated testing. Isadora Agency and Credera worked accessibility into full redesigns of navigation and page structure.
Remediation suits a working site that fails specific checks. For a site due for replacement, accessibility can go into the design brief.
WCAG AA is the usual benchmark
Most of the work on this list is measured against WCAG level AA, under versions 2.0 through 2.2. Virtusa's bank project, for example, tested against AA under WCAG 2.0. Level AAA adds stricter success criteria. Isadora's HVIP site meets AA, and an Isadora article describes the project as designed to meet AAA.
What website accessibility work costs
On Isadora Agency's inquiry form, the website and product design budget opens at $95K and climbs to a $401K-plus band. The testing specialists in this group scope audits and programs after reviewing a site and don't post rates.
Accessibility costs rise with the number of templates and components, PDFs and other documents that need fixing, video that needs captions, third-party widgets outside the team's control, and how often testing continues after launch. A quote that prices the audit and the fixes as separate lines makes firms easier to compare.
