Which prebuilt Stripe component should be used for customers to manage their subscriptions and billing details?

The Customer Portal is the prebuilt Stripe component specifically designed to allow customers to manage their subscriptions and billing details in a secure and user-friendly manner. This component provides a customizable interface where customers can view their current subscriptions, update their payment information, change billing details, and make adjustments to their plans or subscriptions as needed.

Using the Customer Portal enhances user experience by providing a self-service option for customers, reducing support inquiries related to billing and subscription management. It integrates seamlessly with Stripe's billing services, ensuring that updates are accurately reflected in real-time.

Other options like Payment Link, Checkout, and Stripe Terminal serve different purposes such as facilitating one-time payments or in-person transactions, but they do not offer the comprehensive management features for subscriptions and billing details that the Customer Portal provides. Thus, for managing subscriptions and billing details, the Customer Portal is the optimal choice.
