I need a production-ready hospital management ERP that mirrors the depth and polish of platforms such as Health Plix, but branded and tailored for my own facility chain. The build must cover three fully functional core modules from day one—patient management, staff management, and inventory management—so clinicians, administrators, and storekeepers can work from a single, cohesive system. Patient flows are top priority. The software must let front-desk staff handle patient registration in seconds, doctors review longitudinal medical records at the point of care, and schedulers fill, move, or cancel appointments without data loss or double booking. For the team side, I expect clean employee records, drag-and-drop shift scheduling, and built-in payroll management that can export to common accounting packages. Finally, the stockroom needs live inventory counts, automatic low-stock alerts, and simple purchase-order generation to stop out-of-stock situations. I am open to the stack you propose—whether a robust web framework (Django, Laravel, .NET, or similar) or an ERP layer on top of something like Odoo—so long as the UI is responsive, role-based permissions are airtight, and the database design keeps PHI secure and auditable. Integration hooks (REST or GraphQL) are essential, as I will eventually link the system to labs and imaging vendors. Deliverables • Source code with clear installation instructions • Seed data and unit tests proving patient registration, appointment scheduling, and record lookup work end-to-end • Admin panel covering employee files, shift calendar, and payroll run sample • Inventory dashboard with at least one automated reorder rule • Deployment script or container setup (Docker, Helm, or similar) for staging and production Acceptance criteria: all features above demonstrated on a staging URL, zero critical bugs, average page load under three seconds on hospital LAN, and documentation detailed enough for in-house IT to pick up future maintenance. Timelines and milestones are flexible if communicated early, but I would like an initial demo within four weeks. Let me know the tech stack you recommend, any comparable projects you have shipped, and a brief outline of your approach.
