Mollie HQ is in Amsterdam, when should I choose Mollie over Adyen?

Both are Amsterdam-HQ’d, both ship official Magento Marketplace modules, both are excellent payment-engineering teams, but they’re different products targeting different segments. Choose Mollie when: monthly GMV under €1M, you want flat per-txn fees (no enterprise negotiation needed), you sell mainly NL + BE + DE + FR, you want one dashboard for iDEAL + Bancontact + Klarna + SEPA + cards, and you don’t need POS unification. Mollie’s pricing is famously transparent, published on their website, and onboarding is typically under 48 hours. Choose Adyen when: GMV over €5M, you operate globally (US + EU + APAC), you need unified online + retail POS (Adyen Terminal), you negotiate enterprise rates per market, or you need Adyen for Platforms (marketplace splits, sub-merchant onboarding flows). For the €1M, €5M middle band we usually run a Mollie primary + Adyen failover setup, resilient against either-side outage and gives you price-leverage in annual renewals. Both engineering teams have offices walking distance from each other in Amsterdam, so when you hit a hard problem you can get engineer-to-engineer help fast.
