We unified the review/payment experience with a clarity-first order summary, explicit fees/taxes, and a consistent ETA copy system (e.g., “Ready today 5–6 PM”). Operational rules (capacity, cut-offs, store closures) were translated into UI guardrails and standardized status chips across review, payment, and post-purchase. Patterns were built as reusable DS components for web/app parity.
Outcomes (Targets/Early): −5–10% drop-off at Review/Payment, −8–12% median checkout time, −10–20% support tickets about fees/ETA per 1k orders, +20–30% delivery velocity via DS reuse.
