Why agencies are asking about this now

Web accessibility lawsuits in the US keep climbing, and they don't target large companies. When a small e-commerce client gets a demand letter, the first call goes to the agency that built the site.

3,117federal web accessibility lawsuits filed in 2025, up 27% year over year
64%of defendants had revenue under $25 million
~70%of cases involved e-commerce sites

How it works

  1. Send a URL

    Any client site — Shopify, WooCommerce, WordPress, custom. We start with a free automated scan so you can see the format before committing to anything.

  2. We audit

    Automated scan of the key pages, then manual review: full keyboard navigation, screen reader pass on the critical flows, forms, images, contrast. Five business days.

  3. You deliver

    A prioritized report with each issue, its severity, where it is, and how to fix it — white-labeled, so your client sees your agency, not ours. Remediation and monthly monitoring available.

About Plumbline

Plumbline started with a measurement. In 2025, federal courts in the United States received more than 3,100 web accessibility lawsuits, most of them against e-commerce businesses with under $25M in revenue. We scanned the portfolios of the agencies that build those stores and found that two out of three client sites carried barriers a screen-reader user could not get past. The agencies had built good work; nobody had checked it against WCAG.

Plumbline exists to do that check, and to let agencies deliver it under their own name. Every review combines an automated scan with a manual walkthrough by a person, because the failures that matter — a checkout that can't be completed with a keyboard, a form whose errors are never announced — don't show up in software.

Plumbline is founded and run by Agustín Rodríguez, Software Engineer and Industrial Engineer, based in Buenos Aires, Argentina.
