Start with 2Checkout — highest vibe code, weakest moat.

2Checkout

2Checkout operates as a Merchant of Record (MoR) and payment gateway, taking legal responsibility for global sales tax, VAT remittance, card network compliance, and local payout settlement.

  • Basic recurring billing and subscription engine
  • Customer self-service billing management portal
  • Product catalog and plan pricing configurations
  • Transaction logs and revenue analytics dashboards

  • Automated sales tax and VAT/GST calculation and local remittance
  • Access to localized payment methods in 200+ countries/territories
  • PCI-DSS Level 1 audit coverage for payment processing
  • Global chargeback defense and fraud risk management infrastructure

real moats

  • Merchant of Record legal entity network and money transmitter licenses
  • Direct acquiring banking relationships and global settlement rails
  • International cross-border tax remittance systems and legal compliance

Klarna

You can easily build a UI component that breaks a total price into four installments. You cannot build a multi-billion dollar debt capital engine, real-time credit underwriting platform, and regulated banking entity with a prompt.

  • Checkout split-payment UI widget and price breakdown display ("4 payments of $25").
  • Basic schedule calculator for Pay-in-4 or Pay-in-30 plans.
  • Merchant backend dashboard showing order authorization status and order lists.
  • Consumer-facing installment payment schedule view and manual pay-now button.

what you lose

  • Zero consumer credit default risk (Klarna pays the merchant even if the buyer defaults).
  • Instant shopper recognition across millions of stores via saved credit profiles.
  • Access to Klarna's high-converting consumer app store directory and affiliate ecosystem.
  • Full regulatory compliance management (FCRA, TILA, state-by-state lending licenses).
  • Turnkey fraud protection and chargeback management on installment orders.

real moats

  • Regulated banking status and sponsor bank capital relationships (WebBank) allowing compliant loan origination across jurisdictions.
  • Proprietary underwriting algorithms trained on decades of consumer repayment data across millions of checkout events.
  • Massive consumer distribution channel via the Klarna shopping app, driving high-intent affiliate traffic to merchants.
  • Direct merchant integration embedded directly into default payment gateways (Shopify Payments, Stripe, Adyen).
