Which Stripe product provides core functionality for Marketplaces and SaaS Platforms?

Stripe Connect is the product specifically designed to provide core functionality for marketplaces and software as a service (SaaS) platforms. It facilitates complex payment flows that are essential for platforms that connect buyers and sellers or support multiple users utilizing various transactions.

With Stripe Connect, businesses can enable features such as onboarding users, managing payments, and handling compliance requirements. It allows platforms to easily split payments among different parties, automate payouts, and manage the monetary transactions between users while also offering flexibility to customize the payment experience based on the platform's needs. This capability is critical for marketplaces that need to manage multiple vendors or service providers and for SaaS platforms that may charge their users while distributing revenue or commissions.

In contrast, Stripe Radar focuses on fraud prevention and security measures rather than payment infrastructure for marketplaces. Stripe Atlas assists businesses in incorporating and setting up operations, which does not directly relate to transaction management. Stripe Issuing is about creating and managing virtual and physical cards, which is not the primary feature necessary for marketplace transactions. Thus, Stripe Connect stands out as the ideal solution for enabling the payment framework that marketplaces and SaaS platforms require.
