Use multi-step only when the form is genuinely longer (qualifier + contact + details).\n\n**Why:** Zuko ([[zuko-multi-step-only-helps-above-7-fields]]) reports the multi-step lift evaporates below 7 fields and may go negative. The headline \"multi-step forms 3× single-step\" stat ([[formstack-multi-step-13-9-vs-4-5-pct-2014]]) reflects longer forms in the underlying dataset, not pagination per se. Adding steps to a 4-field contact form **costs clicks for no measurable conversion lift**.\n\n**How to apply:**\n- Contact / inquiry forms: name + email + 1-2 short fields = single step\n- Quote request forms: vertical selector + contact details + service-specific fields = multi-step makes sense, with the vertical selector as step 1 (the value is internal lead routing, not conversion lift — see [[zuko-multi-step-only-helps-above-7-fields]] caveat)\n- \"Multi-step boosts conversion\" claims used in pitches: cite [[venture-harbour-multi-step-300pct-lift]] correctly (NOT CXL) and disclose the field-count threshold","rationale_body":null,"metadata":null,"links":{"outgoing":[{"slug":"zuko-multi-step-only-helps-above-7-fields","title":"Zuko: multi-step forms only outperform single-page above ~7 fields; below that, neutral or worse","kind":"reference","scope":"business","link_type":"depends-on"},{"slug":"venture-harbour-multi-step-300pct-lift","title":"Venture Harbour: multi-step forms up to 300% better than single-page — correctly attributed (NOT CXL/ConversionXL)","kind":"reference","scope":"business","link_type":"depends-on"},{"slug":"formstack-multi-step-13-9-vs-4-5-pct-2014","title":"Formstack 2014: multi-step forms 13.9% vs 4.5% single-step (n=450k+ accounts) — directional, not RCT","kind":"reference","scope":"business","link_type":"depends-on"}],"incoming":[{"slug":"research-brief-ia-multi-vertical-service-business","title":"Research brief: Information architecture for service businesses with multiple verticals (piece 6 of 15)","kind":"reference","scope":"business","link_type":"relates-to"}]},"created_at":"2026-05-22T19:40:49.161Z","updated_at":"2026-05-22T19:40:49.161Z"}
