axelor/axelor-open-suite — reverse-engineered prompt

Build me an open source business management suite like Axelor Open Suite. I want a modular app where a company can start with basic customer and sales tracking, then turn on more areas later without rebuilding everything. It should cover CRM, sales, accounting and cost tracking, HR, projects, inventory, supply chain, production, purchasing, helpdesk, fleet, contracts, budgets, marketing, and customer or supplier portals if those modules are enabled.

Please include support for multiple companies, currencies, and languages, because it should work for businesses in different countries. Make the user experience feel like a real ERP, with clear menus, forms, lists, search, reports where useful, and simple workflows for everyday staff.

Use Java and the Axelor Open Platform approach, and structure it so each business area is its own module. If you need setup details, look up the current Axelor docs online. Get it running locally with sensible sample data so I can click around and demo it.
