We build hospital management systems, nursing agency platforms, clinic ERP, healthcare CRM, and ABDM-compliant software — tailored to your workflows, with full source code ownership and zero vendor lock-in.
Get a Free Consultation WhatsApp UsKarnataka is home to some of India's most demanding healthcare institutions — Narayana Health, Aster CMI, Manipal Hospitals, Apollo, and Fortis. Each operates differently. Generic, packaged HMS products are designed for an average use case that fits no one precisely.
Custom healthcare software solves what packaged products cannot: the software works exactly the way your hospital works, not the way the vendor decided hospitals should work. Patient registration follows your UHID format. Billing applies your exact tariff structures. Nursing notes capture the fields your clinical team actually uses.
At OneCity Technologies, we have been building custom software for businesses across Karnataka since 2017. In June 2026, we deployed our most comprehensive healthcare platform yet — a 120-module Hospital ERP covering every operational domain from patient registration through AI-powered clinical decision support. OneCity Technologies Pvt. Ltd (CIN: U72100KA2009PTC048911) has operated from Bengaluru since January 2009.
OneCity does not sell a software subscription. We build your software — custom-developed for your hospital's specific workflows. You receive full source code ownership. No monthly licensing fees. No vendor dependency. The software is yours permanently.
Six software categories where OneCity has built production systems for Karnataka healthcare organisations — each custom-developed, not configured from a template.
Full-stack hospital ERP covering OPD, IPD, pharmacy, lab, radiology, billing, insurance, and administration. Our 120-module platform covers every clinical and operational workflow. NABH-compliant, ABDM-integrated, GST-ready.
Shift scheduling, credential tracking, WhatsApp notifications to nurses, client portal, digital timesheets, payroll integration, and Android app for nurses. Built for Indian nursing staffing agencies — no equivalent Indian product exists.
Patient relationship management: appointment booking, follow-up automation, WhatsApp reminders, referral tracking, corporate client management, and analytics dashboards for multi-location healthcare groups.
Appointment-first clinic software for single or multi-branch clinics — patient records, consultation notes (ICD-11), prescriptions, lab integrations, billing, and the ABDM patient portal required under Ayushman Bharat Digital Mission compliance.
Revenue cycle management, cost accounting, budgeting, GST e-invoicing (CGST Rule 49), payroll with EPF/ESI/TDS, vendor management, and purchase procurement — integrated across clinical and administrative departments.
Native Android and iOS apps for patients (appointment booking, health records, teleconsultation), doctors (consultation workflows, prescription), and nurses (shift management, vitals entry). Built with Flutter for cross-platform consistency.
Our June 2026 platform is a complete hospital operating system built for Indian hospital workflows, Indian regulatory requirements, and Indian healthcare data standards. It is the reference architecture from which we build custom hospital systems for clients — adapting modules, extending functionality, integrating with existing infrastructure.
Every module includes role-based access control (RBAC), a complete audit trail with user/timestamp/action logging, encryption at rest for all patient data, and clinical data coding with ICD-11, SNOMED-CT, LOINC, and RxNorm — the standards required for ABDM interoperability and NABH accreditation readiness.
This is not vaporware or a concept. Our 120-module platform is a live, deployed system developed entirely by OneCity's in-house team. Clients commission custom systems built on this proven architecture — not a demo that becomes a custom project.
The live ERP is accessible at myonecity.in/onecity-erp. Demo access for prospective hospital clients is available on request. Contact us at onecity.co.in/contact-us or call +91 99023 30233.
India has hundreds of nursing staffing agencies supplying nurses to hospitals across Karnataka. Every one of them manages operations on WhatsApp groups, Excel spreadsheets, and phone calls — because no Indian software company has built a dedicated nursing agency management platform. OneCity has.
A Bangalore nursing agency placing 200 nurses across 40 hospital clients manages: nurse availability per shift, credential verification (nursing council registration, vaccination records), client requirements per shift (ICU-trained vs general ward, day vs night), timesheet collection, invoicing to hospitals, and payroll to nurses. Managing this at scale on WhatsApp produces errors, double-bookings, missed shifts, and disputed timesheets.
No Indian software company has a dedicated nursing agency software development page. Mangaluru and coastal Karnataka produce a disproportionate share of India's trained nurses. Nursing agencies in this region are managing operations manually. OneCity is building the first platform for this market.
The Ayushman Bharat Digital Mission (ABDM) is the regulatory framework that all healthcare providers and software systems interfacing with health data in India must comply with. It is not optional.
ABDM creates India's national health data ecosystem — every patient has an ABHA (Ayushman Bharat Health Account) ID, every provider is on the Health Facility Registry (HFR), and records are shared electronically with patient consent. Technical standards: HL7 FHIR R4 for data exchange, SNOMED-CT for clinical terminology, ICD-11 for diagnoses, LOINC for lab observations.
Patient registration must support 14-digit ABHA ID creation (Aadhaar or mobile-based) and linking. Our module handles ABHA creation, linking existing IDs, and ABHA address (@abdm) assignment.
Hospital software must register as a Health Information Provider (HIP) and Health Information User (HIU). Our platform handles ABDM sandbox registration and production deployment.
All health records shared via ABDM must conform to HL7 FHIR R4 format. Our clinical data is stored and exported in FHIR-compliant structures — enabling interoperability with any ABDM-connected system in India.
National Health Claims Exchange — our billing module generates NHCX-format claims for cashless insurance processing, eliminating manual TPA portal switching for billing staff.
Government scheme support: Pradhan Mantri Jan Arogya Yojana (PMJAY), Central Government Health Scheme (CGHS), and Ex-Servicemen Contributory Health Scheme (ECHS) — scheme eligibility, pre-authorisation, and claim submission within the billing workflow.
Reference: Ayushman Bharat Digital Mission official guidelines (abdm.gov.in) — authoritative source for ABDM compliance requirements.
Our quality management module is 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, and indicator reports for NABH assessors.
The Digital Personal Data Protection (DPDP) Act 2023 creates legal obligations for healthcare organisations. Our platform implements AES-256 encryption at rest, TLS 1.3 in transit, RBAC with least-privilege access, a complete audit trail, and automated data retention aligned with MCI guidelines.
Most hospital administrators evaluate MocDoc, Ezovion, Care Conquer, and custom development as equivalent alternatives. They are not — they are fundamentally different in ownership, flexibility, cost structure, and long-term control.

The right choice depends on scale and requirements. For a 10-bed clinic with standard workflows, a packaged product may be appropriate. For a 100-bed+ hospital or multi-location group, custom development produces better long-term economics. Contact OneCity — we will tell you honestly which approach suits your situation.
Healthcare software development requires a higher standard than standard application development. Clinical workflows, patient safety, data security, and regulatory compliance mean errors have consequences beyond business inconvenience.
We spend time with your clinical and administrative teams at your facility — mapping actual workflows. We document every exception and workaround, because custom software should fix those, not replicate them.
We design the data model, API structure, RBAC hierarchy, and integration map before writing any application code. Schema decisions at this stage determine ABDM FHIR export capability and analytics scalability.
Development proceeds module by module, each tested against clinical workflows before the next begins. HMS core delivers in 4–6 months; full 120-module platform in 12–18 months.
User Acceptance Testing is conducted with your actual clinical and administrative staff using real workflows — not scripted test cases. We are present at your facility during UAT, not just available by phone.
Our team is on-site during go-live week. Clinical staff receive role-specific training; IT staff receive system administration documentation. We remain available 24/7 during the first 30 days post-launch.
Annual maintenance covers security patches, OS compatibility updates, bug fixes, and a defined quota of enhancement requests. You are never billed for fixing our own bugs.
Module descriptions drawn directly from our deployed June 2026 platform documentation — not marketing copy.
Our ED module implements a 5-level triage system (Red/Orange/Yellow/Green/Blue — aligned with Manchester Triage System and Emergency Severity Index standards). The module includes: rapid registration with minimum required fields for unconscious or unidentified patients, a trauma documentation interface with body-map injury marking, resuscitation log with timestamped interventions (intubation, IV access, drugs administered), and MLC (Medico-Legal Case) flagging with automatic Section 357C CrPC compliance documentation for police intimation.
ED disposition tracking — admit, discharge, transfer, LAMA, death — feeds directly into bed management and billing, eliminating the manual handover between ED and ward nursing stations that causes documentation gaps in most Bangalore hospitals.
ICU charting is the highest documentation-burden area in any hospital. Our ICU module replaces paper nursing flowsheets with hourly digital charting: vitals (HR, BP, SpO2, temperature, CVP, ICP), ventilator parameters (mode, FiO2, PEEP, tidal volume, respiratory rate), and fluid input/output balance. APACHE II and SOFA scores are calculated automatically from entered vitals and lab values — no manual calculation by nursing staff.
Hospital billing is India's most complex billing environment: OPD charges, IPD daily tariffs (room-type-dependent), pharmacy dispensing, lab tests, radiology procedures, OT surgeon and anaesthetist fees, procedure charges, and service charges — all from different departments, consolidating into a single patient bill with GST-compliant invoice format under CGST Rule 49.
The NHCX (National Health Claims Exchange) integration enables direct electronic claim submission to insurance companies without manual portal entry. Insurance and TPA management covers: pre-authorisation request generation with clinical documents attached, cashless claim processing, denial management with appeal documentation, and final claim settlement.
A 200-bed hospital employs 400–600 staff. Managing attendance, leave, shifts, payroll with statutory deductions, and performance evaluation on Excel or disconnected tools is one of the most common operational pain points from Bengaluru hospital administrators.
Our HRM module covers the complete employee lifecycle: onboarding with digital document collection (Aadhaar, PAN, nursing council certificate, medical fitness certificate), attendance through biometric integration or manual marking, leave management with automatic accrual and encashment calculation, shift roster scheduling, and monthly payroll processing with EPF (12% employer + 12% employee), ESI (3.25% employer + 0.75% employee), Professional Tax (Karnataka slab), and TDS computation.
The Nurse Management module adds: license number verification against Karnataka Nursing Council register, specialisation tracking (ICU-trained, OT scrub nurse, paediatric, dialysis), patient-nurse ratio monitoring against NABH standards (1:6 for general wards, 1:3 for ICU), and performance evaluation records that feed into annual appraisal documentation.
Our executive dashboard gives the medical superintendent and CEO real-time visibility into the metrics that determine hospital performance: bed occupancy rate across all wards (target 80–85% for financial sustainability), average length of stay by department and diagnosis, revenue per occupied bed per day, and OPD/IPD patient volumes vs the same period last year.
The clinical analytics layer gives department heads the data to drive quality improvement: surgical site infection rates by procedure type, catheter-associated urinary tract infection rates in ICU, medication error frequency by nursing unit, and 30-day readmission rates by diagnosis — the indicators that NABH assessors and hospital accreditation bodies examine closely. External reference: NABH — the National Accreditation Board for Hospitals & Healthcare Providers.
Karnataka's healthcare ecosystem is one of India's most complex — and most demanding. A development partner with no Karnataka healthcare experience regularly misses requirements that a local team would know instinctively.
Karnataka is home to the headquarters of Narayana Health (1,600+ beds in Bengaluru), Manipal Hospitals (Karnataka origin), Aster CMI, Apollo, and Fortis — institutions operating at enterprise scale. Their software requirements differ fundamentally from community hospitals.
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.
Dakshina Kannada and Udupi districts produce a disproportionate share of India's trained nurses. Mangaluru-based nursing agencies supply hospitals across Karnataka and internationally. The operational software gap in this sector is acute and entirely unaddressed by existing Indian products.
Karnataka hospitals serve patients in Kannada, Tulu, Kodava, Konkani, Hindi, and English. Patient registration, discharge summaries, and patient-facing communications need multilingual capability that generic national products rarely provide.
Karnataka has 65+ RGUHS-affiliated medical colleges. Teaching hospital software requirements — medical student training records, research data exports, case mix indexing, MCI audit readiness — are significantly more complex than community hospital requirements.
Bengaluru (Rajajinagar), Mangaluru (Kankanady), Mysuru (Kuvempu Nagara). We conduct on-site discovery, training, and go-live support across Karnataka without the travel overhead that Bengaluru-only developers face for Mangaluru or Mysuru clients.

Mobile Apps →Core HMS (patient registration, OPD, IPD, pharmacy, billing, lab, radiology) for a 50–100 bed hospital: ₹12–25 lakh, 6–9 months. Full 120-module platform with AI, ABDM, mobile apps, ERP finance: ₹35–70 lakh, 12–18 months. Nursing agency software: ₹6–12 lakh, 3–5 months. Healthcare CRM with WhatsApp integration: ₹4–8 lakh, 2–4 months. These are indicative ranges — we provide a fixed-price proposal after the discovery phase, with no scope creep billing.
Minimal viable HMS (10 core modules): 4–5 months. Full hospital ERP (30 core modules + clinical departments + integrations): 9–14 months. The most common timeline extension cause: delayed sign-off on clinical workflows during discovery, or UAT feedback requiring significant rework — both avoidable with a thorough discovery phase.
Both options are available. Cloud deployment on AWS Mumbai or Azure India West is recommended for most hospitals — lower infrastructure management overhead, automatic scaling, geographic redundancy. On-premise deployment is available for hospitals with data sovereignty requirements or existing server infrastructure they want to utilise. You are not locked into a hosting provider.
Yes. Lab analyser interfaces via HL7 2.x messaging to LIS, PACS/DICOM integration (DICOM Modality Worklist, DICOM viewer), accounting system integration (Tally, Zoho Books, SAP), and third-party API integrations with government portals (ABDM, PMJAY). Integration feasibility and cost are assessed during the discovery phase.
Our quality management module is 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, and indicator reports. The software creates the infrastructure for NABH compliance; clinical governance practices determine whether accreditation is achieved.
We provide fixed-price proposals with defined timelines after a discovery phase. We guarantee: specific deliverables will be completed as scoped, content and functionality will meet defined quality standards, and we will report honestly on progress. We do not guarantee specific outcomes (rankings, patient volumes, accreditation) that depend on factors outside our control.
