We build hospital management systems from scratch — OPD, IPD, pharmacy, lab, radiology, billing, insurance, ABDM, and NABH quality management. 120 modules. Full source code ownership. No monthly licensing fees.
Get a Free Consultation WhatsApp UsA 500-bed multispecialty hospital in Bengaluru has fundamentally different workflow requirements from a 30-bed nursing home in Mangaluru or a dialysis chain across 12 locations in Karnataka. Generic packaged HMS products — MocDoc, Ezovion, Care Conquer, OmniWorks — are designed for an average use case that fits no one precisely.
Custom hospital management software development solves what packaged products cannot: the software works exactly the way your hospital works. Patient registration follows your UHID format. Billing applies your exact tariff structures. Ward nursing notes capture the fields your clinical team actually uses. Reporting outputs match the formats your medical superintendent and CEO require — not the formats the software vendor decided were standard.
At OneCity Technologies, we deployed a 120-module Hospital ERP in June 2026 — our most comprehensive healthcare platform to date. It covers every operational domain from patient registration through AI-powered clinical decision support. This platform is the reference architecture from which we build custom hospital systems for our clients — adapting modules, extending functionality, and integrating with existing hospital infrastructure. Clients do not buy the platform; they commission a custom hospital system built on our proven module architecture.
OneCity Technologies Pvt. Ltd (CIN: U72100KA2009PTC048911) has been building custom software for Karnataka businesses since 2017, with offices in Bengaluru (Rajajinagar), Mangaluru (Kankanady), and Mysuru (Kuvempu Nagara).
The decision between custom development and a packaged product is not about quality — both approaches can produce good software. It is about whether your hospital's operational workflows are standard enough that a packaged product's design assumptions match your reality. If your OPD patient flow, billing structure, clinical documentation requirements, and departmental reporting needs match what MocDoc or Ezovion offer out of the box, a packaged product is faster and cheaper. If they do not — and for most hospitals above 50 beds in our experience, they do not — custom development eliminates the ongoing friction of adapting your hospital's operations to someone else's software design decisions.
OneCity delivers full source code to the client. No monthly licensing fees. No vendor dependency. No subscription that increases annually. The software is yours — you can host it, modify it, or hire another developer to extend it. This is a fundamentally different ownership model from MocDoc/Ezovion/Care Conquer subscriptions where you licence access to software you never own.
Every module includes role-based access control, audit trail logging, AES-256 encryption at rest, and clinical data coding with ICD-11, SNOMED-CT, LOINC, and RxNorm.

What these modules actually do in practice — descriptions from our deployed platform documentation.
5-level triage (Red/Orange/Yellow/Green/Blue — Manchester Triage System aligned). Rapid registration for unconscious/unidentified patients. Trauma documentation with body-map injury marking. Resuscitation log with timestamped interventions. MLC flagging with automatic Section 357C CrPC documentation. ED disposition tracking (admit/discharge/transfer/LAMA/death) feeds directly into bed management and billing.
Hourly digital charting replacing paper flowsheets: vitals (HR, BP, SpO2, temperature, CVP, ICP), ventilator parameters (mode, FiO2, PEEP, tidal volume), fluid I/O balance. APACHE II and SOFA scores auto-calculated from entered values. ICU bed occupancy dashboard across all units — general, cardiac, neonatal, neurosurgical — from a single screen. Step-down criteria checklists for structured ICU-to-ward transfer decisions.
India's most complex billing environment handled in one module: OPD charges, IPD daily tariffs (room-dependent), pharmacy, lab, radiology, OT fees, procedure charges, consumables — all consolidating into one GST-compliant patient bill (CGST Rule 49). E-invoice IRN generation from GST portal. NHCX integration for cashless insurance claims. TPA management: pre-auth, cashless processing, denial management, final settlement. PMJAY/CGHS/ECHS scheme eligibility and claim submission within the billing workflow.
Three workflows most standalone pharmacy tools handle separately: inpatient dispensing (ward requests), outpatient dispensing (OPD prescription auto-loaded into pharmacy queue), and inventory management (FIFO, expiry tracking, near-expiry alerts, auto-reorder on minimum stock). Drug interaction checking at point of dispensing against our interaction database. Narcotic register (Schedule H and H1), return medication handling, and CDSCO-compliant inventory reconciliation.
400–600 staff in a 200-bed hospital. Complete employee lifecycle: onboarding with digital document collection (Aadhaar, PAN, nursing council certificate), biometric attendance, leave management with auto-accrual, shift roster scheduling, monthly payroll with EPF (12%+12%), ESI (3.25%+0.75%), Professional Tax (Karnataka slab), TDS. Nurse Management adds: license verification against state nursing council, specialisation tracking, patient-nurse ratio monitoring against NABH standards (1:6 general, 1:3 ICU), performance evaluation records.
Real-time metrics for the medical superintendent and CEO: bed occupancy rate (target 80–85%), average length of stay by department, revenue per occupied bed per day, OPD/IPD volumes vs previous year. Clinical analytics: surgical site infection rates, CAUTI rates in ICU, medication error frequency, 30-day readmission rates — the indicators NABH assessors examine. Standard MIS, revenue, discharge statistics, lab turnaround, and OT utilisation reports pre-built and schedulable. Custom reports via no-code report builder.
MocDoc, Ezovion, Care Conquer, OmniWorks, and custom development are not equivalent alternatives — they differ fundamentally in ownership, flexibility, cost, and long-term control.

For a 10-bed clinic with standard workflows, a packaged product may be appropriate. For a 100-bed+ hospital or multi-location group with specific workflow requirements, custom development produces better long-term economics. Contact OneCity — we will tell you honestly which approach suits your situation.
Pricing transparency is unusual in the Indian software development market. We publish indicative ranges because informed clients make better project decisions.
All prices exclude GST. Fixed-price proposal provided after discovery phase. Annual maintenance: 15–20% of development cost. No mandatory escalation.
We spend time at your facility mapping actual workflows — OPD patient flow, admission process, ward rounds, nursing handover, billing, discharge. We document every exception and workaround because custom software should fix those, not replicate them.
Data model, API structure, RBAC hierarchy, ABDM FHIR export capability, analytics scalability. Schema decisions at this stage determine whether the system can handle 500 daily patients without performance degradation.
Module-by-module development, each tested against clinical workflows. HMS core (registration, OPD, IPD, billing, pharmacy): 4–6 months. Full 120-module platform: 12–18 months. We integrate incrementally — not build-everything-then-test.
Your clinical and administrative staff test with real workflows. We are physically present at your facility during UAT. Issues are fixed before go-live, not after.
On-site during go-live week. Role-specific training: nurses, billing staff, doctors, lab technicians, administrators. Printed user guides per role. 24/7 phone support for the first 30 days.
Security patches, OS updates, bug fixes, defined enhancement quota. You are never billed for fixing our own bugs. New modules and major features scoped and quoted separately.
Every hospital system we build includes ABDM integration from the architecture level — not added as an afterthought. ABHA ID creation and linking, HIP/HIU registration, HL7 FHIR R4 health record export, electronic consent management, and NHCX insurance claims. Reference: abdm.gov.in
Built to NABH Hospital Accreditation Standards (5th Edition) — KPI tracking across all NABH chapters, incident reporting with root cause analysis, CAPA management, accreditation document repository, indicator reports for assessors. The software creates the infrastructure for compliance; clinical governance determines accreditation. Reference: nabh.co
AES-256 encryption at rest, TLS 1.3 in transit, RBAC with least-privilege access, complete audit trail, automated data retention and purging aligned with MCI guidelines for medical records (minimum 3 years, longer for surgical records).
If you supply nurses to hospitals (not manage them within one), our Nursing Agency Platform covers shift scheduling, credential tracking, WhatsApp automation, and digital timesheets from the agency's perspective.
Karnataka's healthcare ecosystem has specific requirements that national or international software vendors consistently miss.
Karnataka hosts the headquarters of Narayana Health (1,600+ beds Bengaluru), Manipal Hospitals (Karnataka origin), Aster DM Healthcare (major Karnataka presence), Apollo, and Fortis. These institutions need enterprise-grade software that generic HMS products cannot deliver. Their workflows involve cross-departmental integrations, multi-location data consolidation, and compliance requirements that exceed what packaged products offer.
Karnataka Medical Council (KMC) registration, Karnataka Private Medical Establishments Act (KPME), and state-specific pharmacy regulations add Karnataka-specific compliance layers beyond national NMC and ABDM frameworks. A developer with no Karnataka healthcare experience will miss these state-specific requirements — building software that passes functional testing but fails regulatory audit.
Bangalore hospitals serve patients in Kannada, Tamil, Telugu, Hindi, Urdu, and English. Coastal Karnataka adds Tulu, Konkani, and Kodava. Patient registration forms, discharge summaries, consent documents, and patient-facing communications need multilingual support that generic national products — designed primarily for Hindi and English — rarely provide at the depth Karnataka hospitals require.
Karnataka has 65+ RGUHS-affiliated medical colleges. Teaching hospitals need software that handles medical student training records, research data exports, case mix indexing, and MCI audit readiness — requirements significantly more complex than what community hospitals need and what most packaged HMS products support.
Karnataka hospitals process claims under PMJAY (Ayushman Bharat), CGHS, ECHS, and state-specific schemes like Arogya Karnataka and Yeshasvini. Each scheme has different eligibility criteria, package rates, pre-authorisation workflows, and claim submission formats. A hospital billing module must handle all active schemes within one unified billing workflow — not require separate portals for each scheme.
Bengaluru (Rajajinagar), Mangaluru (Kankanady), Mysuru (Kuvempu Nagara). We conduct on-site workflow discovery, UAT, training, and go-live support anywhere in Karnataka without the travel overhead and time-zone delays that Bengaluru-only or out-of-state developers face for hospitals in Mangaluru, Mysuru, Hubli, or tier-2 Karnataka cities.
The Bangalore software development market has hundreds of companies that will take a hospital software project. Most will deliver something that technically functions. Very few will deliver clinical-grade software that hospital staff actually use, that survives an audit, and that scales as the institution grows. These questions help distinguish genuine healthcare software specialists from general-purpose developers learning healthcare on your project.
Has the development team spent time in actual clinical environments — OPDs, pharmacies, nursing stations, ICUs — physically mapping how work happens? Software built by developers who have never observed a nursing handover will have a nursing documentation module that looks correct on paper but fails in practice because it does not match how nurses actually document care. Ask specifically: "Can your team walk me through the triage-to-discharge workflow for an emergency admission in a 100-bed hospital without referring to documentation?" A team with genuine clinical software experience can do this.
Healthcare software in India in 2026 must use specific clinical data standards to be ABDM-interoperable and NABH-audit-ready. The correct answers are: ICD-11 for diagnoses, SNOMED-CT or RxNorm for medications, LOINC for lab observations, and HL7 FHIR R4 for health record exchange. A developer who answers "we use our own internal code sets" is building a system that cannot exchange data with any ABDM-connected system and cannot produce NABH-standard discharge summaries. This is not a minor limitation — it is an architectural flaw that cannot be retrofitted without a database rebuild.
Hospital software cannot have unplanned downtime during clinical operations. A billing failure during OPD peak hours halts revenue operations. A pharmacy module failure affects patient medication dispensing. Ask: what is the SLA for critical issue resolution (should be 4 hours or less), is there a 24/7 emergency contact, and what is the written definition of "bug" vs "enhancement"? The ambiguity between bug and enhancement is the most common source of post-launch disputes in hospital software projects.
Patient health data is among the most sensitive personal data any organisation holds. The Digital Personal Data Protection (DPDP) Act 2023 creates legal obligations for healthcare organisations handling this data — breach notification requirements, data minimisation obligations, and consent management. Ask your prospective developer: how is patient data encrypted at rest? What is the access control model? Is there an immutable audit trail? How does the system handle data retention and purging when a patient requests deletion? What is the data breach response protocol? A developer who cannot answer these questions specifically — with named encryption algorithms, access control methodologies, and audit trail architecture — has not built healthcare-grade software before. Our platform implements AES-256 encryption at rest for all patient records, TLS 1.3 for data in transit, role-based access control with least-privilege principle, and automated data retention aligned with MCI guidelines.

We are transparent about our strengths and limitations. Strengths: physical presence across Karnataka enabling genuine on-site discovery, a production-deployed 120-module ERP built by our own team (not licensed from another vendor), and 22 years of business experience in Karnataka's market.
Limitation: we are not a 500-developer IT services company. We are a focused Karnataka-based agency. We take on healthcare software projects where we are confident in delivery — and decline projects outside our capability. If we assess that your requirements need a different developer, we will tell you.
22 years in business. CIN: U72100KA2009PTC048911. Offices: Bengaluru, Mangaluru, Mysuru. The 120-module hospital ERP described on this page was built by our in-house team and deployed June 2026.

Core HMS (registration, OPD, IPD, pharmacy, billing, lab, radiology) for 50–100 beds: ₹12–25 lakh, 6–9 months. Full 120-module platform with AI, ABDM, mobile apps: ₹35–70 lakh, 12–18 months. Fixed-price proposal after discovery phase, no scope creep billing.
Minimal viable HMS (10 core modules): 4–5 months. Full ERP (30+ modules with integrations): 9–14 months. Most common delay: late sign-off on clinical workflows during discovery or UAT rework — both avoidable with thorough discovery.
Yes. Lab analysers via HL7 2.x, PACS/DICOM integration (Modality Worklist, DICOM viewer), accounting systems (Tally, Zoho Books, SAP), and government portals (ABDM, PMJAY). Integration scope assessed during discovery.
Our quality module covers NABH 5th Edition — KPI tracking, incident reporting, CAPA, accreditation document repository, indicator reports. The software provides compliance infrastructure; clinical governance practices determine accreditation.
Both. AWS Mumbai or Azure India West recommended for most hospitals. On-premise for data sovereignty needs or existing server infrastructure. You are not locked into any hosting provider.
Ownership model: they sell subscriptions to software they own; we build software you own. Their product is one-size-fits-many; ours is built for your specific workflows. Their monthly fees accumulate to ₹9–48 lakh over 5 years with no code ownership. Our one-time cost delivers permanent ownership. For hospitals with standard workflows and small budgets, their products may be appropriate. For hospitals with specific requirements, custom development is the better long-term investment.
