Question 28 · Sep 12 · Day 3

Claude on Question 28, Sep 12

Which is better: Adyen or Stripe? Pick one.

Stripe, for most people asking this question.

Why Stripe wins by default:

  • •Developer experience is genuinely best-in-class. The docs, SDKs, test mode, and error messages are a real competitive moat. Integration time is often days rather than weeks.
  • •You can sign up yourself and be taking payments the same afternoon. No sales calls, no contract negotiation, no volume minimums.
  • •The surrounding product suite is deeper — Billing for subscriptions, Connect for marketplaces, Tax, Radar for fraud, Issuing. If you need recurring billing or payouts to third parties, Stripe does more out of the box.
  • •Ecosystem effects. More engineers have used it, more tools integrate with it, more Stack Overflow answers exist.

Where Adyen actually beats it — and it's not a small carve-out:

If you're processing serious volume (roughly $50M+ a year), operating across many countries, and have physical retail alongside e-commerce, Adyen is usually the better choice:

  • •Cheaper at scale. Adyen quotes interchange++ transparently (interchange + scheme fees + a small fixed processing fee per transaction, on the order of €0.10–0.12, plus a payment-method markup). Stripe's blended 2.9% + 30¢ is fine for small volumes but expensive at large ones — you can negotiate interchange-plus with Stripe at scale, but Adyen tends to land lower.
  • •Single-platform "unified commerce." Adyen is gateway, acquirer, and risk engine in one, with direct acquiring licenses in most major markets. Fewer intermediaries often means measurably better authorization rates, which at scale can dwarf the fee difference.
  • •Stronger in-person/POS story, and a single view of a customer across online and in-store.

The tradeoff: Adyen requires a sales process, has effective volume minimums, onboarding takes weeks, and the documentation and self-serve tooling are noticeably less polished.

The short version: start on Stripe, and re-evaluate Adyen when payment costs become a line item your CFO cares about or when you open physical locations. That's the actual crossover point — not a philosophical preference.

**Stripe**, for most people asking this question.
**Why Stripe wins by default:**
- **Developer experience is genuinely best-in-class.** The docs, SDKs, test mode, and error messages are a real competitive moat. Integration time is often days rather than weeks.
- **You can sign up yourself and be taking payments the same afternoon.** No sales calls, no contract negotiation, no volume minimums.
- **The surrounding product suite is deeper** — Billing for subscriptions, Connect for marketplaces, Tax, Radar for fraud, Issuing. If you need recurring billing or payouts to third parties, Stripe does more out of the box.
- **Ecosystem effects.** More engineers have used it, more tools integrate with it, more Stack Overflow answers exist.
**Where Adyen actually beats it — and it's not a small carve-out:**
If you're processing serious volume (roughly $50M+ a year), operating across many countries, *and* have physical retail alongside e-commerce, Adyen is usually the better choice:
