I remembered a similar forum post last year. I'm pasting my colleague Laurie's response below.
I feel that as the developing agency, you need to do everything you can to ensure the website is ADA compliant and meets the required standards. However, I would not put yourself in a position to certify that it is ADA compliant. The client should work with an independent source to audit the site and make any recommendations for changes needed to comply. You can make those changes and the audit can be finalized once everything is completed to satisfaction.
It's also a good idea to set periodic audits for the site as new regulations are added or things change. You want to be sure the site stays in compliance once built and that will entail some ongoing work.
If you make it a collaborative effort between the agency, client and auditing company, everything should work out fine.
Our agency has had experience in building a website that meets standards from the ground up and then auditing another agency's code and making suggestions.
Our dev team used a combo of sources for guidelines, like https://www.w3.org/WAI/WCAG20/quickref/ and https://www.powermapper.com/products/sortsite/checks/accessibility-checks/. We then worked with the client to determine if we should aim to meet, A, AA or AAA standards. From there, working closely with our design and dev teams to see how that would change their process and add hours.
Our developer utilized a resource to review a site we’ll be launching soon and we adjusted a lot of the details so that it would pass compliance (we were told after design started that it needed to be compliant, so you’re starting at the right time ; ). The resource charged $5,000. Feel free to contact me at firstname.lastname@example.org if you’re interested in connecting with them for your potential project.
