Handing an accessibility report to a client is a different conversation depending on what is in it. Here is how to make it land well.
Lead with the risk band, not the score
"High Risk" is something a non-technical client understands immediately. A score of 61 out of 100 is not. Use the band to frame the conversation, and the score to show movement over time.
Send the Expert-Verified report, not the automated one
An automated report says "a tool found these things". An Expert-Verified report says "a certified specialist checked this". That distinction matters to a client who is going to share it with their own stakeholders or legal team. If you do not yet have a review, say so clearly rather than sending automated results without context.
Translate the issue list
Clients do not need to read about ARIA attributes. They need to know: these are the things stopping some of your visitors from using your site, this is how serious each one is, and this is what fixing it looks like. Pull out the two or three most impactful issues and lead with those.
Frame it as progress, not a grade
If this is not their first scan, lead with what has improved. A score rising from 72 to 84 is a better story than a score of 84 in isolation, and it shows the work is having an effect.
Keep the report
Encourage your client to keep every Expert-Verified report. A dated series showing improvement is valuable evidence if they ever face a complaint or a regulatory question.
