The models' case: The default for a reason — Express/Custom/Standard onboarding flows handle KYC, identity verification, and 1099/tax reporting out of the box. The models' main caveat: Card-processing economics (2.9%+ plus Connect fees) are expensive at scale, and pushing large flows off-platform or negotiating rates is hard until. The strongest alternative is Adyen for Platforms — Enterprise-grade single-stack acquiring + payouts with genuine global reach, local acquiring to lift auth rates, and Adyen-issued balance accounts.
