Stripe uses AI to personalize checkout experiences through dynamic payment ordering, fraud prevention, and layout adaptation

The problem

Tailoring checkout to individual customers requires dynamic real-time responsiveness to a wide range of subtle signals; most businesses settle for one-size-fits-all experiences or run A/B tests that hard-code logic far short of per-customer optimal decisions. Checkout flows also need to handle fraud without blocking legitimate sales or introducing unnecessary friction.

First attempt

Rigid rule-based approaches and A/B testing failed to deliver per-customer optimal decisions. Showing even one geographically irrelevant payment method at checkout can reduce conversion rates by up to 15%.

Fraud risk assessed via Stripe Radar

“seamlessly integrating Stripe Radar, trained on billions of data points across Stripe's global network, and augmenting it with an extensive set of contextual signals only available through the Optimized Checkout Suite”

Dynamic checkout interventions applied
output
“the Optimized Checkout Suite dynamically adjusts checkout interventions based on the likelihood of different types of risk—blocking scripted attacks, ensuring that customers are who they say they are, and getting ahead of fraud”
Reported outcome

When at least one additional relevant payment method beyond cards is dynamically surfaced, businesses see on average a 12% revenue increase and a 7.4% increase in conversion rates.
Applying fraud interventions selectively reduces fraud rates by 30% on average with minimal impact on conversion.
