Two production-ready modules for marketplace financial operations: a double-entry ledger engine and a multi-vendor escrow service. Built with TypeScript, MongoDB transactions, and comprehensive test coverage.
Each module is independently deployable and comes with full documentation, tests, and API documentation.
Production-ready double-entry accounting system with MongoDB transactions, hold/release mechanics, and multi-currency support.
Multi-vendor marketplace escrow with Shopify webhook integration, commission splits, and vendor payout management.
Built with best practices for production fintech applications.
MongoDB transactions ensure atomic operations. All-or-nothing execution prevents partial state.
Full type safety with strict null checks, exact optional properties, and no implicit any.
Every transaction creates balanced entries. Debits always equal credits by design.
Automatic retry with exponential backoff for transient MongoDB write conflicts.
HMAC signature verification for Shopify webhooks prevents unauthorized access.
44 tests across both modules covering unit, integration, and edge cases.
Test the APIs directly in your browser with our Swagger UI documentation.
Our Swagger UI provides full "Try it out" functionality. Create accounts, execute transfers, test escrow flows — all live.
