Six rules for neutral marketplace software interviews with verified sellers

These six practices make marketplace seller software customer interviews useful for one England merchant decision. They do not produce customer testimonials, sales permission, demand estimates or evidence about the whole market.

Method: A practice qualified when it reduced a specific research risk and a current UK professional or official record supported that boundary.

Research date: 6 September 2026.

England and UK scope: Recruitment concerns a verified England seller operation. UK professional standards and government methods retain their stated scope.

Inclusions: Neutral interviews with authorised seller staff, decision-makers or adult customers who meet a recent-event screener.

Exclusions: Cold sales calls, supplier demonstrations, invented respondents, unsafe live transactions, review solicitation and inference from public profiles.

Ranking: Non-ranked. The order follows preparation, fieldwork and analysis.

Conflicts: The editorial team received no recruitment fee, referral payment or private findings from any party discussed.

1. Confirm the role before the story

Verify the legal seller, marketplace account and participant's part in a recent listing, stock, order, return or refund event. HMRC's digital-platform seller guidance supplies a narrow reporting definition, not proof of authority. Ask what the participant actually did and which record shows it. Exclude anyone whose role cannot be confirmed.

2. Give information before seeking agreement

Send the purpose, activities, observers, recording, uses, recipients, retention, incentive and withdrawal route in an accessible format. The GOV.UK informed-consent guide says participants should understand these points and be able to stop. Research permission does not authorise marketing or marketplace contact.

3. Ask about one recent episode

Begin with the last qualifying event, then trace its trigger, records, hand-offs, exception and finish. GOV.UK guidance on in-depth interviews recommends stories and real examples rather than generalities. Do not ask whether a hypothetical tool would be useful before understanding the present work.

4. Use open, neutral prompts

Ask "What happened next?" or "Which record did you open?" Avoid wording that assumes the system failed or automation is wanted. The UK Statistics Authority's qualitative-research ethics guidance explains how leading questions can affect responses and credibility. Keep a versioned guide so interviewers cover the same topics.

5. Make participation workable

Ask invitees what format, timing, communication support or assistive technology they need. Government guidance on research sessions with disabled people advises planning around the participant's own setup and communicating directly with them. Do not infer disability or diagnosis from a device, role or response.

6. Separate the transcript from the conclusion

Store notes, approved quotations, documentary evidence, researcher interpretation and unknowns in different fields. The MRS Code of Conduct, binding on MRS members and Company Partners, addresses participant interests and transparent reporting. It is not legal advice. Verify quotations with participants where identification or meaning could be material, and preserve contrary cases.

After the interviews, report invitations, eligible participants, completions, field dates, instrument version and missing roles. Qualitative accounts can explain a workflow. They cannot establish England-wide frequency, budget or demand. Stop if permission cannot be matched to the data, live customer details appear unexpectedly or a participant is being asked to judge outside their competence.

Retain counts of refusals and early endings without speculating about the reasons. Those records help readers see who the final accounts do not represent.
