Flat-rate simplicity versus interchange-plus scale — the two processors serve very different stages of growth.

Which one wins for which use case
Early-stage and mid-market SaaS or marketplace startups doing most volume online will usually find Stripe's transparency and developer tooling faster to launch with. Larger, multi-channel, or heavily cross-border businesses processing well above $1M a month are the ones for whom negotiating Adyen's interchange-plus terms tends to pay off.
