Test the templates. Fix the source. Keep the receipts.
Three ideas do most of the work. None of them is clever — they are just what the job actually requires.
1. Templates, not pages
A catalogue of 10,000 products is not 10,000 accessibility problems. It is one product template with the same handful of issues repeated 10,000 times.
We discover your URLs from your sitemap, then cluster them by URL pattern and page structure. Testing runs against a sample of each cluster, and every finding records how many URLs its template represents. Your report says so plainly:
Checkout and account flows are scanned on every run regardless of clustering, with a real signed-in session. That is where the barriers that stop people buying actually live, and it is where automated tooling most often never reaches.
2. Two kinds of testing, labelled as such
Automated testing detects roughly 30–40% of WCAG success criteria. Any vendor implying otherwise is selling you the easy 30%. Every finding in your report is tagged with the method that produced it, so you always know which is which.
3. The record is the deliverable
Reports are nice. What matters over time is the running history: every issue found, when it was found, what was done about it, who did it, and which scan confirmed it. Append-only, exportable, and yours.
It is also the thing that is worth something if anyone ever asks what you have been doing. Demonstrable, dated, continuous effort is a far better position than a badge in your footer.
