Companies focused on digital accessibility provide comprehensive services: implementation of WCAG/EAA, audits, development of accessible websites and applications, training, and long-term support. World leaders such as Deque, Level Access, TPGi, Funka, AccessiBe, or EqualWeb are involved in the development of standards and provide top-notch tools for testing and validating WCAG. When choosing, it is important to verify certification, market experience (e.g., collaboration with W3C or IAAP), references, and the ability not only to test but also to make real adjustments and train the client's team.
