our call
Start with SellersFi — highest vibe code, weakest moat.
Mollie
You cannot replace Mollie with an AI prompt because Mollie is an authorized European payment institution with regulated money movement rails.

- Hosted checkout payment pages and payment links.
- Merchant dashboard UI for manual refunds, customer list, and transaction history.
- Basic recurring billing schedules and subscription state management.
- Webhook dispatch engine with signature verification.
- Multi-currency payment payload normalization.
what you lose
- Access to De Nederlandsche Bank payment institution licensing under PSD2/PSD3 regulations.
- Direct settlement contracts with European acquirers, card schemes, and local APMs.
- Managed chargeback defense mechanisms and automated fraud detection systems.
- Out-of-the-box support for physical hardware POS terminals and Tap to Pay frameworks.
