India-Compliant Hospital Management System

I need a full-fledged Hospital Information Management System built to Indian standards. Core functionality must cover patient record management, appointment scheduling, and integrated billing & invoicing, and the same codebase has to run smoothly in both clinics and multi-specialty hospitals without major rework. If you already have a proven product, I’d like to see a working demo immediately; if you plan on building from scratch, walk me through your tech stack, timeline, and how you will meet local compliance such as NDHM/ABDM, NABH, HL7 or FHIR where applicable. Deployment can be cloud, on-premise, or hybrid, but all data must remain on servers physically located in India with full role-based access control, audit logs, prescription printouts in local languages, and standard ICD-10 libraries baked in. Deliverables • Complete HIMS application with source code • Installation package or container images for clinic and hospital instances • Technical & user documentation • Post-launch support plan (bug fixes, minor enhancements) I will approve the project after a live walkthrough on my test server and a brief code review. Please outline similar Indian healthcare projects you’ve handled, the stack you prefer (PHP/Laravel, .NET, Java Spring, Node, etc.), and the realistic timeframe to get a production-ready release in my hands.
