Question 28 · Sep 17 · Day 8

Claude on Question 28, Sep 17

Which is better: Adyen or Stripe? Pick one.

Stripe, for most companies. But the reasoning matters more than the verdict, because the answer flips at scale.

Why Stripe is the better default

  • •Self-serve signup and the best developer experience in the industry — you can be taking payments in a day, not after a three-month sales and integration cycle.
  • •Enormous product surface beyond processing: Billing/subscriptions, Connect for marketplaces, Radar for fraud, Tax, Issuing, Terminal. If your business needs recurring billing or multi-party payouts, Stripe gives you that out of the box rather than as something you build.
  • •Huge ecosystem — nearly every SaaS tool, ecommerce platform, and accounting system has a native Stripe integration.
  • •Documentation and community mean your engineers have probably already used it.

When Adyen is clearly the right pick

  • •You're processing serious volume (roughly $50M+/year, and especially $100M+). Adyen's interchange++ pricing with a small fixed fee per transaction gets meaningfully cheaper than Stripe's blended rates, and at that scale a 20–30bps difference is a line item your CFO cares about.
  • •You have real omnichannel needs — physical retail plus online, in multiple countries, on one platform with unified reporting. This is Adyen's strongest suit (it's why McDonald's, Uber, and large retailers use it).
  • •You need local acquiring across many markets. Adyen holds its own acquiring licenses and processes on a single stack end-to-end, which typically yields higher authorization rates and lower cross-border costs than routing through partners.
  • •You have an in-house payments team who can optimize routing and retries. Adyen gives you levers; it expects you to pull them.

The tradeoffs to be honest about

Adyen has no self-serve onboarding, thinner product tooling around billing and marketplaces, and a monthly minimum invoice. Stripe costs more at scale, and smaller merchants occasionally hit account-review or freeze issues that are frustrating to resolve.

Bottom line: if you're a startup, a SaaS business, a marketplace, or doing under ~$20M/year, Stripe — the speed and product breadth outweigh the pricing premium. If you're a large enterprise with physical retail and multi-country operations, Adyen, and it's not close. Many companies at scale end up running both for redundancy and routing optimization.
