Getting paid quickly is what every webshop owner wants. A good payment service provider lets your customers pay in seconds and gets that money to you safely. And offering a choice of methods, like iDEAL, PayPal, credit card and Afterpay, gets invoices paid faster and lifts your conversion.

But which provider should you pick? Two names come up again and again: Adyen and Mollie. Both are Dutch, both rank among the world’s top 20 fintechs, and both are excellent. The catch is that they are built for different kinds of business. This guide compares Adyen vs Mollie on setup, pricing, support and features, so you can choose the right one for your store.

Adyen vs Mollie: the short answer

The difference comes down to the size and complexity of your business.

Adyen is built for larger companies. It offers deep customisation, global coverage and hands-on onboarding, and is trusted by names like Spotify and HelloFresh.

Mollie is built for smaller businesses and the SME market. It is quick to set up yourself and easy to use from day one.

Neither is “better” in general. The right choice depends on where your business is now and where it is heading. Here is the full comparison.

Meet Adyen and Mollie

What is Adyen?

Adyen is a listed payment service provider that offers payment solutions for businesses, and it leans towards larger companies with more complex needs. It sits in the world’s top 20 fintechs, and well-known names like Spotify and HelloFresh run their payments through it.

A group of entrepreneurs founded Adyen in Amsterdam in 2006. From the start, the goal was to help businesses grow, which meant the platform had to keep up with the fast-changing needs of modern commerce. Over the years it added support for streaming services, subscription boxes, memberships and risk management tools, turning it into a full payment platform rather than a simple checkout button.

That breadth is Adyen’s signature. If your business sells across multiple countries, runs subscriptions, or needs fine control over every step of the payment flow, Adyen is built for exactly that scale.

What is Mollie?

Mollie is an unlisted payment service provider that processes online payments for merchants and other organisations. It is one of the five most valuable fintech companies in Europe and a regular in the global top 20. Where Adyen chases enterprise, Mollie focuses on smaller businesses and the SME market.

Adriaan Mol started Mollie in 2004. It began by selling text messages to business customers and handling micropayments for online gaming and ringtones, then added payment services from 2006. That history shows in the product: Mollie is designed to be simple, fast to adopt, and friendly to businesses that do not have a technical team.

If you want to start accepting payments this week, without contracts or sales calls, Mollie is made for that.

Setup: is Adyen harder than Mollie?

Yes, and that is by design. The two providers onboard you in very different ways.

With Adyen, you start by contacting their support team. Based on your requirements, they advise you on the payment solution that best fits your business. You then get a test account, where you can explore the features and make your first test payment. Once you are happy and have signed the contract, you go live. It is more involved, but that guidance pays off for complex or high-volume setups.

With Mollie, you simply create an account and follow a step-by-step onboarding plan that Mollie provides. The roadmap walks you through the setup so you can start receiving online payments quickly, entirely on your own. No phone call, no contract negotiation.

In short: Adyen invests time up front to tailor things to you, while Mollie gets you live fast with a self-serve flow.

Pricing

Both providers keep the model clean: no minimum fees, no contracts, and no monthly charges. You only pay when a transaction succeeds.

Adyen: transaction fees start at 0.10 per transaction.

Mollie: transaction fees start at 0.29 per transaction.

The exact fee depends on the payment method your customer chooses. Adyen’s lower base fee can favour higher-volume businesses, while Mollie’s straightforward pricing is easy to predict for a growing store. Always check the current rates for your specific payment mix before deciding.

Support

Support is where the two clearly differ. Mollie offers a support page that answers user queries. Adyen goes further with a dedicated platform of experts who provide advice and support 24/7. On support depth, Adyen has the edge, which matches its focus on larger businesses that need help fast.

Features compared

Both platforms have extensive features across payments, dashboards, integration and administration. Since payments are the core, here is how their payment features line up.
