Adyen

Also called Adyen N.V., Adyen for Platforms

The Dutch enterprise processor global brands use for one platform across every country. Not an SMB product, but increasingly behind ones you use.

What it is

Adyen is a Dutch payments company built around a single global platform: one integration, one contract, one reporting layer covering online, in-app and in-store acceptance across dozens of countries and hundreds of local payment methods. It prices on interchange++ — interchange, scheme fees and Adyen's markup shown separately — which is the most transparent pricing structure in payments and also the one that requires the most sophistication to read. Adyen's customer base is enterprise and large mid-market: global retailers, marketplaces, hospitality groups and fintechs. It sells direct, runs its own terminals, and does not operate an SMB agent channel. Adyen for Platforms serves software companies at enterprise scale. What makes Adyen newly relevant to smaller merchants is indirect. In August 2026, Adyen became a US processing partner for Toast, after previously supporting Toast in Ireland, the UK, Canada and Australia. That means a growing share of American restaurants are running on Adyen's rails without knowing it, and it signals that Toast is diversifying processing — a move usually driven by cost pressure and redundancy needs.

Why it matters to your business

You are unlikely to buy Adyen directly, and that's fine. What matters is recognizing the name when it appears behind a platform you use, because it tells you something: the platform is optimizing its own processing costs. Toast adding Adyen in the US is a signal that Toast's own cost of processing is under pressure — which is exactly the kind of pressure that eventually shows up as a rate change for you. Interchange++ is also the pricing model worth knowing by name. It's what Adyen shows enterprises: interchange, scheme fees and markup, all separate. When you ask a processor for interchange-plus pricing, that's the same idea one level down. If a processor won't break those three components out, they're choosing not to.

Where it gets contested

There isn't a merchant-complaint file on Adyen the way there is on PayPal or Toast, largely because Adyen doesn't serve the merchants who generate those complaints. Its criticism is about accessibility: minimum volume expectations put it out of reach for small businesses, onboarding requires real integration work, and support is structured around enterprise account management rather than a phone number a restaurant owner can call. The more interesting critique is about disintermediation. When Adyen powers a platform like Toast, the merchant's relationship is with the platform, and Adyen's excellent pricing structure produces no transparency for the end merchant — interchange++ visibility stops at the platform. Merchants gain the reliability and lose the legibility. Adyen has also had a public reckoning with growth expectations, seeing its stock fall sharply when growth and hiring costs disappointed investors, followed by a strategic reset. That is a shareholder story more than a merchant story, but it explains why Adyen has been more aggressive about winning platform business like Toast.

How to check it yourself

Ask your processor to show you a statement with interchange, network/scheme fees, and their markup as three separate lines. That's the interchange++ structure Adyen shows enterprise clients. If you can't get three lines, you're on bundled pricing regardless of what it's called.
