our call
Start with Paydock — highest vibe code, weakest moat.
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

Paydock
Building conditional payment routing logic in AI is trivial, but operating a PCI-DSS Level 1 card vault is an absolute dealbreaker for DIY builds. Paydock's core value is isolating your infrastructure from PCI compliance scope while maintaining normalized integrations to dozens of changing PSP APIs.
you can rebuild
- Rule-based routing logic using currency, amount, or geography
- Primary and secondary gateway failover state machines
- Unified transaction status logs and basic analytics dashboard
- Normalized internal charge and refund requests API
- Webhook ingestion and status synchronization pipelines
what you lose
- PCI-DSS Level 1 compliance scope reduction for cardholder data
- Zero-scope hosted card fields and client-side iframe tokenization
- Pre-built maintenance for 30+ payment processor API specifications
- Processor-agnostic token vaulting independent of underlying PSPs
- Enterprise-grade uptime SLAs and sub-second payment failover
real moats
- PCI-DSS Level 1 security compliance and audit isolation
- Broad maintenance of volatile third-party payment gateway APIs
- Independent card tokenization vault decoupled from specific PSPs
