our call
Start with Billie — 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. While writing a checkout UI and subscription state machine with AI is simple, you cannot prompt an AI to grant money transmitter licenses or negotiate banking acquirer contracts across 200 countries.

- Customer self-service billing management portal
- Product catalog and plan pricing configurations

Billie
Billie is not a software tool; it is a financial institution and risk-taking engine that advances working capital and assumes default risk for B2B buyers across Europe. Prompting a checkout UI is trivial, but an LLM cannot provide balance sheet capital, perform credit scoring via Creditreform, or legally collect defaulted B2B debt.
you can rebuild
- Checkout UI payment modal for selecting invoice payment terms
- Basic merchant dashboard for tracking transaction statuses
- Custom invoice PDF generation and emailing trigger
- Order status webhooks for ecommerce platforms
- Manual net-terms account approval interface
what you lose
- 100% default protection (non-recourse risk transfer to Billie)
- Real-time B2B credit scoring and instant buyer credit limit decisions
- Upfront cash payout to the merchant regardless of buyer payment delays
- Automated cross-border European debt collection and legal processing
- BaFin and EU financial regulatory framework compliance
real moats
- Balance sheet liquidity to fund 30-120 day credit windows at scale
- Proprietary B2B credit risk models built on historical European company dataset
- Regulatory licensing and banking partner integrations for invoice factoring
