- Rules engine for payment routing based on country or currency.
- Webhook payload parsing and status aggregation dashboards.
- Basic payment method selection UI (iDEAL, Klarna, Apple Pay wrappers).
what you lose
- Direct Interchange++ pricing models that pass true card cost savings through to large merchants.
- Local acquiring licenses in 30+ markets that boost card authorization rates by 2-5%.
- Omnichannel transaction unification across e-commerce backends and physical terminal fleets.
- Zero-dependency financial rails (Adyen does not rely on third-party processor banks).
- Enterprise risk engines (3D Secure 2 authentication and dynamic exemption management).
real moats

Alma
Alma is a regulated financial institution (ACPR licensed) that advances capital to merchants upfront while taking on consumer credit risk, fraud, and debt recovery. Building a checkout widget that splits payments via Stripe is trivial, but operating the underlying balance sheet, risk models, and legal debt collection cannot be replaced with code.

- Checkout UI widget displaying 3x/4x or deferred payment breakdown options
- Automated customer notification emails and SMS payment schedules
- Merchant administration interface to view payment status and manually issue refunds
- Plugin integrations for Shopify, WooCommerce, PrestaShop, and Magento
- Scheduled charging engine utilizing off-session card tokens via payment gateways
what you lose
- 100% non-recourse merchant payouts upfront regardless of whether the buyer defaults
- Regulated EU payment institution and consumer credit licensing (ACPR compliance)
- Proprietary cross-merchant credit risk scoring algorithms and fraud mitigation
- Automated debt recovery operations and integration with European collection agencies
- Pre-approved consumer network with saved payment profiles across Alma merchants
