Software requirement specification (SRS) for a hospital management system

A clear software requirement specification (SRS) for a hospital management system is the difference between a project that ships and one that drifts. Whether you are scoping a build, writing an RFP, or evaluating off-the-shelf software, this template gives you a complete, adaptable structure — grounded in how a real HMS like MedOps is actually organised.

1. Purpose

The purpose of the system is to manage the clinical and administrative operations of one or more hospitals from a single platform: patient registration, appointments, consultations, inpatient care, pharmacy and billing — with secure, role-based access and a complete audit trail.

2. Scope

The hospital management system shall support multiple hospitals under a single organisation (tenant), with every record scoped to its hospital. It shall cover the outpatient and inpatient journeys end to end, integrate the pharmacy, and generate billing — while enforcing least-privilege access for each category of staff.

3. User roles

• Tenant Admin — manages hospitals, users, settings and reporting across the organisation.
• Doctor — appointments, consultations, e-prescriptions and inpatient rounds.
• Nurse — ward and clinical support (vitals, observations).
• Operations / front desk — patient registration, appointment booking and bills.
• Pharmacy — stock, dispensing and invoicing at the pharmacy counter.

4. Functional requirements

• FR-1 Patient management — register patients with a unique MRN; maintain demographics and full visit history.
• FR-2 Appointments — book, reschedule and cancel appointments with conflict checks against doctor availability.
• FR-3 Consultations — record notes, diagnoses and a follow-up date; generate an e-prescription on completion.
• FR-4 Inpatient — model floors, rooms and beds; admit, transfer and discharge patients transactionally so a bed is never double-booked.
• FR-5 Pharmacy — maintain a medicine catalogue, record stock-in, dispense against prescriptions, and decrement stock atomically.
• FR-6 Billing — generate consultation and pharmacy bills with paid/unpaid status; store amounts as exact integers (paisa).
• FR-7 Access control — enforce role-based permissions on every action.
• FR-8 Audit — record every significant action with actor, timestamp and context.
• FR-9 Authentication — secure sign-in with inactivity logout and session revocation on logout or password change.

5. Non-functional requirements

• Security — encrypted sessions, hardened HTTP headers, per-IP rate limiting, and tenant isolation so no data crosses organisations.
• Reliability — operations that must agree (e.g. a consultation's prescription and bill) execute in a single transaction.
• Performance — list and search views paginate and respond quickly under realistic load.
• Availability — target high uptime with graceful handling of dependent-service outages.
• Usability — workflows usable at speed by clinical staff; accessible and keyboard-navigable.
• Auditability & compliance — tamper-evident logs; GST-ready billing and ABHA/ABDM readiness for India.

6. Data requirements

Core entities include Tenant, Hospital, User, Patient, Appointment, Consultation, Prescription, Medicine, Bill, and the facility hierarchy (Floor, Room, Bed) plus Admission. Money is stored as integer paisa; significant fields carry created/updated timestamps; and every record references the hospital and tenant it belongs to.

7. Constraints & assumptions

• Delivered as a secure web application accessible to authorised staff.
• Versioned API so integrations remain stable as the product evolves.
• Data residency and retention configured to the organisation's jurisdiction.

Using this SRS

Treat the sections above as a starting point: number each requirement, add acceptance criteria, and prioritise (must / should / could). If you'd rather buy than build, use the same list as an evaluation scorecard — see our guide to choosing the best hospital management software in India, or start from what hospital management software is.

MedOps already implements this specification end to end. Book a demo to walk it on seeded data, or explore the features and platform.
