## Overview

This is a small Node/Express ERP proof of concept: a browser dashboard loads customer data, summary metrics, and database health, and can submit new customers. The server exposes those API operations and uses PostgreSQL for health checks and customer reads/writes; invoice and revenue figures are demo placeholders. The README describes a customers schema that does not match the insert/read fields shown in server.js, so persistence may require schema alignment. The graph reflects the sampled files and documented capabilities; it does not infer additional ERP modules.

Main entry points: [`public/app.js`](https://github.com/vishal343012/erp-project/blob/main/public/app.js) (Dashboard UI), [`server.js`](https://github.com/vishal343012/erp-project/blob/main/server.js) (Customer API)
