We do about $3m per year selling outdoor gear online, we got served back in August with this lawsuit saying our site violated ADA, they found like 412 violations and wanted $25k to settle. I called our lawyer right away and he basically said we could fight it but it would probably cost $30k or more and we'd likely lose anyway, so our best bet was to fix everything fast and try to negotiate down. The problem was that we had no idea how to fix any of it, our site was built on shopify with a theme we bought a while back and I actually found a solution through reddit which was kind of random, but we got everything scanned and fixed in about 11 days with testparty. We also documented everything proving we'd fixed everything properly, our lawyer used that to negotiate and we ended up settling for $1800 plus monitoring for 6 months. That saved us like $23k which is huge. If you run any kind of online store I'd seriously recommend getting this checked, it's way cheaper to prevent than deal with a lawsuit, like the old saying says, better safe than sorry.
