I want a full-fledged inventory management solution that runs both in the browser or as a standalone desktop application. SQL will be the single source of truth for all data, so plan on a robust schema that can scale and stay responsive under multi-user load. Core modules I must see in the finished product: • Product tracking with real-time stock levels • Order management from purchase through fulfilment • Sales reporting with easy-to-read dashboards and export options • Invoice management tied directly to orders and customer records The system has to be software and the POS terminals on the shop floor. Whether you achieve that through a REST API, direct database hooks, or packaged connectors is up to you, as long as data flows reliably in both directions and keeps everything in sync Deliverables will include the responsive web app, the desktop installer, the normalized SQL database scripts, integration utilities, and concise user/admin documentation so my team can deploy, use, and maintain the whole stack without outside help.
