our call
Start with Splitit — highest vibe code, weakest moat.
Pismo
Pismo is an enterprise core-banking platform handling double-entry ledger accounting, ISO 8583 message streams, and physical/virtual card issuance. AI tools can easily draft a basic double-entry ledger API, but cannot solve sub-50ms scheme authorization latency, PCI-DSS Level 1 compliance, or card network connections.
you can rebuild
- Internal store credit ledgers
- Basic user account balance tracking
- Transaction history REST APIs
- Custom webhook listeners for payment state changes
- Internal admin UI for account management
what you lose
- Direct ISO 8583 and ISO 20022 card network authorization routing
- PCI-DSS Level 1 certified cardholder data environment (CDE)
- Built-in compliance modules for regional payment rails (ACH, PIX, SEPA)
- Multi-region distributed ledger with strict transactional immutability
- Out-of-the-box physical and virtual card tokenization engines
real moats
- PCI-DSS Level 1 certification and regulatory compliance coverage
- Direct connectivity to global card processing networks (Visa/Mastercard)
- High-concurrency micro-ledger architecture designed for 99.999% uptime

Splitit
Building a script to charge a stored payment token every 30 days is straightforward. However, replicating Splitit's core model—holding total purchase amounts against existing credit limits and re-authorizing them without triggering fraud blocks—requires specialized acquirer integration and strict regulatory compliance.
