Build me a simple self hosted ERP and CRM web app for a small business.

I want it to handle invoices, quotes, payments, and customer records, with a clean admin dashboard that feels easy to use. It should also include basic accounting style views and a place for inventory or HR related data if that fits naturally. Use a modern React frontend with a polished Ant Design style, and a Node, Express, MongoDB backend. Make it look professional but straightforward, with login protected pages, forms for creating and editing records, tables for browsing data, and clear totals and statuses on invoices and quotes.

Please set it up so I can run the frontend and backend locally, connect it to MongoDB, and use it as a real starter app I can grow later. If anything needs current setup details, look up the latest docs online. Keep the experience simple and practical, like a real business tool.
