Overview
How might we design personalized checkout so people can trust and act on AI output?
When to use
- Ideal for e-commerce platforms, marketplaces, and retail applications where personalized checkout flows improve conversion rates and user experience.
When to skip
- Guest checkout where personalization requires unknown identity.
- Mandatory fields removed for regulatory or fraud reasons.
- Upsells that distract from payment errors.
Rules
Pre-selected expensive shipping with no prominent edit.
Hiding alternative payment methods behind more.
Personalized upsells that ignore cart contents.
Changing totals after express pay without confirm.
