Adyen: A Story That Shouldn’t Have Happened
In 2006, a group of Dutch developers (including Pieter van der Does and Arnout Schuijff) decided that accepting payments online was a nightmare. Dozens of acquirers, processing centers, local methods, currencies, compliance regimes. Each new market required a new contract and a new integration. They founded Adyen (pronounced “eye-den,” from Surinamese for “start over”) with a single idea: one contract, one API, the whole world.
In 2026, Adyen processes payments for Uber, Spotify, Microsoft, Booking.com, and thousands of enterprise clients. It’s a public company with a €35+ billion market cap. But for small and medium businesses, Adyen was long a closed door. Let’s examine what has changed.

Technology: Not Just “Another Gateway”
Adyen doesn’t resell acquiring — it is an acquirer itself. This is a fundamental architectural difference from Stripe, Paddle, or Mollie, which operate on top of bank acquirers:
Traditional model (Stripe, Mollie): Customer → Payment Gateway → Acquiring Bank → Payment Network → Issuing Bank
Adyen model (direct acquiring): Customer → Adyen (acquirer) → Payment Network → Issuing Bank
By removing the intermediary, Adyen gains:
- Control over the entire payment chain (authorization, clearing, settlement)
- Data on every failure point — optimizing approval rates
- Dynamic routing of transactions between processing centers
- Lower fees for large clients (no acquirer markup)
For enterprise with €100M+ annual volume, this delivers a 2-5% approval rate improvement — millions in additional revenue.
Unified Commerce: Online + Offline
Adyen is one of the few providers that seriously invested in unifying online and offline payments:
Online:
- Hosted Payment Page (HPP) — ready-made payment page
- Drop-in and Components — customizable UI elements
- API — REST API for full control
Offline:
- POS terminals (Adyen Terminal API)
- Tap to Pay (smartphone NFC)
- Cash register system integration
Unified Commerce:
- Single platform for all sales channels
- Customer pays online → sees purchase in app → returns in store
- Unified analytics and fraud protection across all channels
For retailers like H&M or Decathlon, this is critical functionality. For SaaS businesses — overkill, but nice for the future.
RevenueProtect: Machine Learning Against Fraud
Adyen processes tens of billions of transactions — a dataset where ML models become truly accurate:
- Real-time risk scoring (under 100 ms)
- Dynamic rules: block, send to 3DS, pass through
- Customization: your own rules on top of the ML model
- Reports: why a transaction was blocked/passed
Stripe Radar is also good, but Adyen works at volumes Stripe hasn’t yet matched — in the enterprise segment, this is a significant argument.
Global Coverage
Adyen supports 250+ local payment methods in 150+ currencies. Key figures:
- Americas: 26 countries, all major cards + local (Boleto, OXXO, PIX)
- Europe: 39 countries, all local methods
- Asia: Alipay, WeChat Pay, PayNow, GCash, Dana, KakaoPay
- Middle East: Mada, Benefit, KNET, Fawry
For global businesses needing a single solution for payments in Brazil, Germany, and Indonesia — Adyen is often the only vendor covering all three regions under one contract.
Pricing: Individual, Not Public
Adyen doesn’t publish rates on its website. Each client receives a custom proposal based on:
- Annual volume
- Sales geography
- Business model (B2B/B2C, subscriptions/one-time)
- Card vs local method ratio
- Average transaction size
Enterprise benchmarks (€100M+/year):
- Cards: 0.3-0.9% + €0.10-0.20
- Local methods: €0.10-0.25 flat
- Platform: from €500/month per account
For medium businesses (€1-10M/year): Adyen launched an SME program in 2023 — rates closer to 1.0-1.5% + €0.15-0.25, competitive with Stripe for B2B transactions.
Drawback: minimum threshold. Adyen requires €1M+ annual volume for its SME program. Micro-businesses and startups are shut out — they use Stripe, Mollie, or Paddle.
Adyen Partner Program
Adyen’s Partner Program is aimed not at content creators but at system integrators and technology partners:
- Revenue share from implementations
- Co-marketing and joint events
- Certification and technical support
- Not suitable for affiliate models
For content sites with affiliate traffic, Adyen’s partner program is practically useless. If your audience is CTOs of large retailers and platforms, it might make sense. For everyone else — forget about Adyen affiliates.
Candid About the Drawbacks
Adyen is a brilliant enterprise product, but it has objective downsides:
- High entry barrier: SME program requires €1M+ volume. Below that, they won’t even talk to you.
- Complex integration: Adyen requires a technical team. Documentation is excellent, but written for enterprise developers.
- Not a MoR: Adyen, like Stripe, doesn’t solve tax issues. VAT, GST — your problem.
- Custom contracts: no self-service onboarding. Sales, negotiations, contracts — a 2-6 week process.
- Partner program for the chosen few: not suitable for classic affiliate marketing.
Verdict
Adyen is a payment platform for companies that have already grown up. If your volume exceeds €10M and you spend thousands of hours a year on payment issues — Adyen pays for itself with a 2-5% approval rate boost and 30-50% fee reduction vs Stripe. If you’re a SaaS at €50K MRR — Stripe gives 90% of the same for 10% of the effort. And leave Adyen’s partner program to system integrators.
