Suppliers can use the same labels for quite different work. A confident pitch deck tells you little about the scope, evidence, participants, data handling or person who will actually deliver the engagement. The questions below make those differences visible, whichever supplier you're evaluating.
We wrote this because we make these reports for a living, and we'd rather you ask hard questions before you sign than discover the gaps after you've paid. Each question below includes why it matters and, transparently, how we answer it ourselves — so you can hold any supplier, including us, to the same bar.
The 9 questions
1. Can I see a sample usability testing or accessibility report?
Why ask it: A report full of vague observations ("navigation could be clearer") is not useful to a designer or developer. A good report ties every finding to evidence and a specific, actionable fix. Ask to see one before you commit budget.
2. Will I get recordings or transcripts, or just a summary deck?
Why ask it: A summary deck asks you to trust someone else's interpretation with no way to check it. Session evidence — notes, clips or transcripts — lets your team see what actually happened, not just what the supplier says happened.
3. How many participants do you recommend, and why that number?
Why ask it: There is no single correct sample size for every usability study. The useful number depends on the research question, how many distinct user groups you have, and whether the round is a small qualitative study or a larger benchmark. Be cautious of a supplier who quotes the same fixed number for every project without explaining why it fits yours.
4. How will you recruit participants, and what happens to their data?
Why ask it: Recruitment quality determines what the findings can tell you. The supplier should also explain the lawful basis, participant information, recording choices, access controls, retention and deletion process before anyone is recruited on your behalf.
5. How is the test plan built around my specific decision?
Why ask it: A generic research script tells you very little. Ask the supplier to describe the decision your business is trying to make and how the tasks, participants and analysis connect back to it.
6. What's the realistic timeline, and what happens if recruitment runs long?
Why ask it: Recruitment is usually the least predictable part of a study, especially for niche audiences. A supplier who promises a fixed delivery date without acknowledging that risk is setting an expectation they may not control.
7. Who is actually moderating my sessions?
Why ask it: A polished sales conversation can be a different person from whoever actually runs your sessions. Ask for a short, verifiable project history for the person doing the work, not just the person pitching it.
8. Will the findings be usable on their own, or built to sell me more work?
Why ask it: A supplier may also sell design or build work. That can make remediation convenient, but the overlap should be disclosed and the findings should remain useful if you choose another implementation route.
9. Can you test with participants who use assistive technology, not just run an automated scan?
Why ask it: An automated accessibility scanner is a useful starting point, but the W3C is explicit that automated tools cannot determine accessibility on their own. If a supplier's "accessibility audit" is really just an automated scan with a report template around it, you're not getting a manual evaluation.
Red flags worth walking away from
- A guaranteed conversion-rate uplift. Nobody can promise a specific percentage before running the research. A credible supplier tells you what they'll measure and how, not what number they'll hit.
- A promise of full legal accessibility compliance. An evaluation identifies barriers within an agreed scope; it isn't a certification, and no supplier can legally guarantee an entire service complies with a piece of legislation.
- One sample size, every time. If the same participant number appears in every proposal regardless of the research question, it's a template, not a plan.
- An automated scan presented as a complete audit. Ask which checks require human judgement, which pages and states were sampled, and what the conclusion does not cover.
- No willingness to show a sample report or explain who does the work. If a supplier can't or won't answer these nine questions in plain language, that's the answer.
A quick checklist
| Ask this | A credible answer sounds like |
|---|---|
| Can I see a sample report? | Specific findings tied to a standard or heuristic, not vague observations |
| Will I get evidence, not just a summary? | Notes, clips or transcripts where consent allows it |
| Why this many participants? | A reason tied to your research question, not a fixed rule |
| How will you recruit, and what about data? | A named route, screening criteria and a GDPR-aware consent process |
| How does the plan fit my decision? | Reference to your actual journey and business question, not a generic script |
| What's the timeline? | A range that accounts for recruitment risk, not a single fixed date |
| Who runs my sessions? | A named person with a verifiable project history |
| Do findings stand alone? | Yes, whether or not you buy follow-on design/build work |
| Manual accessibility testing available? | Yes — automated tooling plus manual and/or assistive-tech testing |
