Supplier tone: how Hangul microcopy lifted response rates in Scope 3 pilots

Suppliers abandoned our English-only survey at question six. When we swapped to Hangul microcopy with explicit “why this matters to your invoice timing” notes, completion jumped without shortening the questionnaire.

Tone matters more than incentives. Offering gift cards triggered scepticism; explaining how answers protect joint tenders during monsoon season did not.

Archetyping respondents helped. Mom-and-pop vendors received eight questions; strategic partners received the full PCF ladder. The ladder must be visible internally to avoid fairness debates.

Log refusals obsessively. Auditors care less about perfect coverage than about proving you knew where opacity sat and how you proxied it.
