Mollie vs Adyen, which is better for my Dutch Magento store?

Both are excellent and both are Dutch-founded, but they target different sizes of merchant. Mollie is the simpler choice for SMBs, flat per-transaction pricing (~€0.29 + ~1.8% for iDEAL), 2-day onboarding, no monthly fee, and a Magento module that’s a 5-minute install. It supports iDEAL, Bancontact, Klarna, Apple Pay, SEPA, credit cards. Adyen is the better choice for high-volume / enterprise stores, interchange-plus pricing (cheaper at scale), unified global processing, advanced fraud (RevenueProtect), and a much more powerful back-office (financial reports, settlement timing, dispute automation). Rule of thumb: under €5M revenue Mollie wins on simplicity, over €5M Adyen wins on cost. We’ve shipped both and can recommend based on your transaction volume + currencies + cross-border footprint.
