PayPal and Adyen Expand Partnership to Offer Fastlane Accelerated Checkout in the US

PayPal and Adyen have expanded their strategic partnership to offer Fastlane by PayPal to Adyen's enterprise and marketplace customers in the United States.

Fastlane enables guest shoppers to complete online purchases with a single click by recognising returning PayPal users, even when they are checking out on a merchant's website rather than through PayPal directly. The technology works by detecting whether a shopper has a PayPal account and pre-populating their payment and shipping details, eliminating the form-filling that drives high rates of checkout abandonment.

For Adyen's merchant clients, Fastlane integration offers a meaningful improvement in checkout conversion rates. Cart abandonment during the payment process is one of the most costly problems in e-commerce, and reducing the number of steps required to complete a purchase has a direct impact on revenue.

The partnership expansion was announced shortly after PayPal's official Fastlane launch in August 2024. By integrating with Adyen's payment platform, Fastlane gains immediate distribution across a large number of enterprise merchants, including major brands in retail, travel, and digital services that process significant transaction volumes through Adyen.

PayPal said the partnership includes plans to extend Fastlane to additional markets beyond the US, leveraging Adyen's global merchant network to scale the service internationally. The phased rollout will target markets where PayPal has high consumer penetration and where checkout friction represents a significant lost revenue opportunity for merchants.

The expanded partnership reflects the growing interdependence between payment networks, processors, and digital wallets in the e-commerce ecosystem.
