Which is better: Stripe or Adyen? Pick one.

Stripe, for most situations.

The reasoning: Stripe wins on everything that determines whether a payments integration actually succeeds — documentation quality, API design, time-to-first-charge, and the surrounding product suite (Billing for subscriptions, Connect for marketplaces, Radar for fraud, Tax, Terminal). You can sign up yourself and be taking live payments the same day. That matters more than a few basis points of pricing for the vast majority of companies.

When Adyen is genuinely the better answer:

•You're processing serious volume (roughly $50M+/year). Adyen's interchange++ pricing plus their flat per-transaction fee gets meaningfully cheaper than blended rates, and they'll negotiate. At that scale, basis points beat developer experience.
•You're omnichannel retail. Adyen's unified in-store + online platform is genuinely better than Stripe Terminal, with a single view of the customer across channels. This is why H&M, McDonald's, and Nike use them.
•You're heavily multi-region, especially Europe and Asia. Adyen owns its full stack and is a direct acquirer in more markets, which typically means higher authorization rates and broader local payment method coverage. That auth-rate difference can dwarf fee differences.

The practical catch with Adyen: there's no self-serve signup. You go through enterprise sales, there are volume expectations, and integration is a project with a timeline rather than an afternoon. If you're pre-revenue or doing under a few million a year, they're probably not interested and you shouldn't want them anyway.

A note on the common trap: people pick Adyen early "because we'll scale into it" and burn months on integration they didn't need. The reverse migration — Stripe to Adyen once volume justifies it — is a well-worn path that plenty of companies have done successfully. Start with Stripe, revisit when your payments costs become a line item someone in finance complains about.

If you tell me your volume, geography, and business model, I can be more specific.
