Accessibility procurement should request evidence about real user tasks, not only a general statement that a product is accessible. Buyers need to understand tested behavior, known gaps and the process for resolving issues. Vendors should distinguish an internal review from any formal conformance assessment.
The contract to define first
Define representative tasks such as sign-in, navigation, form submission and data inspection. Ask for the applicable standards, review method, date and supported environments. Include keyboard, screen-reader, text-scaling and error-handling evidence where relevant. A checklist can organize the conversation, but it is not a certification by itself.
A worked scenario
A hypothetical buyer evaluates a coach portal using keyboard-only navigation and enlarged text. The vendor should show how client selection, plan editing and validation work in that setup, and identify any limitation. A marketing badge cannot substitute for those observed tasks.
An implementation and review sequence
- Choose representative tasks and supported environments
- Request dated review evidence and known limitations
- Agree an issue-reporting and remediation process
Failure cases worth testing
| Condition or input | Expected behavior |
|---|---|
| A conformance claim lacks a review basis | Ask for the actual method and scope |
| Keyboard cannot complete a core task | Record a concrete procurement gap |
| A limitation is known | It is disclosed with its support plan |

Tradeoffs and limits
A single test environment cannot establish universal accessibility. State the scope and keep an issue-resolution route available as supported browsers and assistive technologies change.
Use the result to make a decision
The practical output is straightforward: prepare reproducible accessibility evidence without claiming certification. Keep the assumptions with the artifact so a product owner, implementer or prospective partner can review the same decision. A useful handoff states the supported scope, the evidence collected and the remaining dependency instead of treating a successful demonstration as proof of every operating condition.

What accessibility evidence should a buyer request?
Accessibility procurement should request evidence about real user tasks, not only a general statement that a product is accessible. A single test environment cannot establish universal accessibility.
Which failure cases should be included in the review?
Include these explicit cases: A conformance claim lacks a review basis: ask for the actual method and scope; Keyboard cannot complete a core task: record a concrete procurement gap; A limitation is known: it is disclosed with its support plan.
