## Overview

PayFlow is a payment-orchestration platform, but this repository snapshot is primarily its Phase 1 React interface and a small Express service shell; the README lists payment-engine capabilities as later development phases. The user-facing path is public product discovery or sign-in, then the merchant dashboard, whose routes expose operational views. The backend starts an HTTP app and attempts a MongoDB connection. Payment routing, ledger, provider, and webhook mechanics are documented capabilities, not verified implementations in the sampled backend. Connections below follow explicit routes, calls, or README statements; unsampled feature internals are not inferred.

Main entry points: [`frontend/src/App.tsx`](https://github.com/samiralam-dot/payflow/blob/main/frontend/src/App.tsx) (Application routes), [`frontend/src/pages/public`](https://github.com/samiralam-dot/payflow/tree/main/frontend/src/pages/public) (Public pages), [`backend/src/app.ts`](https://github.com/samiralam-dot/payflow/blob/main/backend/src/app.ts) (Express application), [`backend/src/server.ts`](https://github.com/samiralam-dot/payflow/blob/main/backend/src/server.ts) (HTTP server)
