The OneCity Advanced Hospital ERP covers 120 — the full operational, clinical, compliance, and intelligence stack that a serious hospital needs, without gaps that force parallel systems for different departments.
The 120 modules are organised into six groups: Core Hospital Operations (30 modules covering the complete patient journey from registration to discharge), Clinical Departments (30 specialty modules from cardiology to paediatrics), Support Services (10 modules for BMW, sterilisation, housekeeping, maintenance), Integrations & Compliance (20 modules covering ABDM, NHCX, PMJAY, HL7 FHIR R4, PACS), AI & Intelligence (10 modules including AI ambient scribe, predictive sepsis alerts, AI billing optimisation), and Administration & Finance (20 modules covering cost accounting, budgeting, credentialing, and executive BI).
The result is a single system where the patient’s entire journey — booking, registration, consultation, admission, investigation, treatment, discharge, billing, and follow-up — flows without data re-entry, paper handoffs, or disconnected records. Every module shares the same patient master, so a bed allocation, a prescription, and a billing line all reference the same verified record.
OneCity Technologies Pvt. Ltd (CIN: U72100KA2009PTC048911) deployed this ERP platform in 2026. Our offices in Bengaluru (Rajajinagar), Mangaluru (Kankanady), and Mysuru (Kuvempu Nagara) provide on-site implementation and training across Karnataka. The live ERP environment is at myonecity.in/onecity-erp.
A Hospital Management System (HMS) covers clinical and patient-flow functions. A Hospital ERP adds the full back-office stack — HR, payroll, procurement, cost accounting, budgeting, contracts, credentialing, and executive BI — integrated with the clinical modules. Most packaged products are HMS with a few finance add-ons. A genuine hospital ERP is the complete operational platform for a hospital that wants to run its entire institution, not just its patient flow, from one system.
Every module is included in the platform. Hospitals deploy the full set or phase modules in by group — the architecture supports either approach.
Six modules that most hospital administrators ask about first, with the specific features from the live system.
Unified billing across OPD, IPD, pharmacy, lab, and radiology — one bill per patient visit, not five separate systems. GST-compliant invoicing with CGST Rule 49 header switching (Tax Invoice vs Bill of Supply by patient category). Multiple payment modes: cash, UPI, card, insurance, scheme. Advance payment and adjustment, interim bills for IPD patients, and final bill on discharge. Revenue reports by department, doctor, and payer.
Prescription-based dispensing with drug verification, batch and expiry tracking, near-expiry alerts, and auto reorder triggers. Drug interaction and allergy alerts at the point of dispensing. Schedule H / H1 / X compliance flags and NDPS register for narcotic drugs. Patient-wise dispensing history, return and exchange handling, and a daily drug report for pharmacy managers.
Lab orders placed from the OPD or IPD consultation screen, routed to the LIS, results entered and verified by the lab, then delivered back to the patient record and the ordering doctor automatically. Sample tracking from collection to result. Critical value alerts for abnormal results. LOINC-coded observations for ABDM FHIR export. Integration-ready for external lab analyser interfaces via HL7 2.x.
Hourly digital nursing flowsheets for vitals, fluid balance, and ventilator parameters. APACHE II and SOFA score auto-calculation from documented values. Medication administration record (MAR) with time-based charting. Central line and catheter insertion date tracking for CLABSI/CAUTI surveillance. ICU-to-ward transfer workflow with handover summary. ICU occupancy dashboard for charge nurses and administrators.
Transcribes the doctor-patient conversation in real time and structures it into the consultation note format — chief complaint, clinical findings, diagnosis, and plan. The doctor reviews and confirms rather than typing the entire encounter from scratch. Reduces documentation time per consultation significantly, particularly in high-volume OPDs where documentation speed is the constraint. Outputs ICD-11 coded diagnoses from the transcription.
Continuously analyses vitals, lab trends, and clinical parameters to generate early sepsis risk scores for IPD and ICU patients. Alerts nursing staff and attending doctors when risk crosses defined thresholds, before clinical deterioration becomes visible. Based on validated sepsis screening criteria (SIRS, qSOFA, NEWS2). Early sepsis detection and intervention is one of the highest-impact patient safety interventions a hospital can deploy.
How a 120-module ERP gets deployed without disrupting a live hospital.
On-site at your hospital. We map every department’s current workflow — how patients move, how staff document, how billing is raised, where the current system breaks. The ERP is configured to match your workflows, not the reverse.
Registration, OPD, IPD, billing, and pharmacy go live first — the modules every patient and every staff member touches daily. Staff build habits on these before more modules are added.
Lab, radiology, ICU, OT, ED, and specialty modules deployed department by department with dedicated training for each team.
ABDM/ABHA integration, NHCX claims, PMJAY scheme handling, and NABH quality module — these run in parallel with the clinical go-live, tested in the ABDM sandbox before production.
AI ambient scribe, predictive sepsis/AKI alerts, and AI billing optimisation are activated once the operational foundation is stable and staff are using the core system confidently.
HRM, payroll, cost accounting, budgeting, procurement, and the executive BI dashboard complete the enterprise layer. The hospital is now running entirely on one platform.
The core use case. Full 120-module deployment, phased over 8–12 months, across all departments. Integrated billing, single patient master, unified reporting.
Eye, dental, cardiac, orthopaedic — deploy the 30 core modules plus the relevant specialty module. Right-sized without enterprise complexity.
Core ERP plus Research & Clinical Trials (Module 111), Cancer Registry (113), and academic reporting modules for MCI/NMC audit readiness.
Multi-location deployment with centralised patient master, branch-wise billing and reporting, and the executive BI dashboard (Module 120) for group-level visibility.
Running a clinic, not a full hospital? Our clinic management software is the leaner version — appointments, EMR, prescriptions, billing, and ABDM, without the inpatient complexity. Same team, right-sized platform.
Every compliance requirement a Karnataka hospital faces in 2026, built into the ERP from the architecture level.
ABHA ID creation and linking at patient registration. HL7 FHIR R4 record export. Health Information Provider (HIP) and Health Information User (HIU) roles fully implemented. Patient consent management with scoped, revocable consent artifacts. ABDM sandbox tested before production deployment. Reference: abdm.gov.in.
Quality Management module covers all NABH 5th Edition chapters — patient care standards, medication management, infection control, facility management, and quality improvement. KPI tracking per NABH chapter, incident reporting (Module 83) with CAPA, and audit trail across all clinical modules. Reference: nabh.co.
Insurance and TPA management with pre-authorisation tracking, cashless claim processing, and rejection management. NHCX format electronic claim submission (Module 62). PMJAY, CGHS, and ECHS scheme eligibility check and claim submission (Module 63). Scheme-wise revenue reporting for management.
All clinical data in the ERP is coded to international standards — the requirement for genuine ABDM interoperability and the baseline for any hospital system in 2026:
A discharge summary generated by the ERP is FHIR R4-exportable, machine-readable by any ABDM-connected system, and carries the coded clinical data that makes electronic health records genuinely useful — not just PDFs in a portal. For a deeper explanation of why this architecture matters, see our ABDM compliance guide.
The most common failure mode in hospital IT is not bad software — it is good software that does not talk to other good software. A billing module that does not know what the pharmacy dispensed. An OT scheduling system that does not feed into anaesthesia records. A lab that prints results on paper for a nurse to re-enter into the IPD nursing notes. These gaps exist because most hospitals accumulate software over time, each product purchased to solve a specific problem, none designed to share data with the others.
A single ERP solves this at the architecture level. Every module shares the same patient master, the same user database, and the same underlying data structures. A lab result ordered from the OPD consultation (Module 4) flows into the LIS (Module 11), is verified by the lab tech, and appears in the patient’s record and the ordering doctor’s worklist without any staff touching it twice. A pharmacy dispensing (Module 13) automatically updates inventory (Module 16) and feeds the billing line (Module 14) without a separate entry. An IPD discharge (Module 7) triggers a follow-up appointment (Module 3) and a final bill (Module 14) in sequence, automatically.
This is not convenience — it is patient safety. The patient who gets the wrong medication because the dispensing pharmacist could not see the OPD allergy record is the cost of disconnected systems. The clinician who cannot see yesterday’s lab result because it is in a different system is making decisions blind. Integration is not a feature; it is the clinical argument for a genuine ERP over a collection of products.
When a hospital runs multiple products from different vendors, the patient data is fragmented across multiple vendor databases — each with its own export format, each potentially inaccessible if the vendor relationship ends. A single ERP with source code ownership consolidates all patient data in one database you own and control. You can export it, migrate it, analyse it, or move it to another system at any time. Under the DPDP Act 2023, data controllership for patient health records sits with the hospital — owning the software makes that controllership meaningful rather than theoretical. For more on data security obligations, see our ABDM compliance guide.
A hospital paying five separate SaaS subscriptions — one each for HMS, billing, pharmacy, lab, and HR — is paying five sets of per-user fees, five support contracts, and five upgrade cycles, with the integration friction of five systems that were never designed to connect. Over five years, a single custom ERP with full source code ownership routinely costs less than the cumulative subscription stack — and you own it at year five instead of paying again at year six. For a detailed cost analysis by hospital size, see our hospital software cost guide.

For a mid-size hospital (50–150 beds) deploying the full ERP in phases, indicative range is ₹35–65 lakh, 10–15 months. Smaller hospitals deploying core operations only (Modules 1–30) start from ₹18–30 lakh. For a detailed breakdown by hospital size, see our hospital software cost guide. All costs are one-time with full source code ownership — no per-user or per-module monthly fees.
Yes. ABDM compliance is built into the architecture — FHIR R4 data structures, ICD-11/SNOMED-CT/LOINC coding at entry, ABHA creation and linking at registration, HIP and HIU roles, and patient consent management via Module 78. This is not a bolt-on; it is designed from the database layer. ABDM sandbox testing is completed before production deployment.
Yes. Module 52 (Quality Management) is built to NABH 5th Edition standards, covering all NABH chapters with KPI tracking, incident reporting with CAPA (Module 83), infection control surveillance (Module 53), and audit trail across all clinical modules. Hospitals using the ERP have the documentation infrastructure NABH surveyors look for.
Core operations (registration, OPD, IPD, billing, pharmacy) go live in 3–4 months. Full ERP including clinical departments, compliance integrations, and administration modules is a 10–15 month programme for a mid-size hospital. Phased implementation means staff are using stable, working software at each stage rather than switching to 120 new modules simultaneously.
Yes. Module 67 (HL7/FHIR Integration) and Module 68 (PACS/DICOM) handle analyser and imaging integrations. Most lab analysers support HL7 2.x bidirectional interface — results flow from the analyser directly into the patient’s LIS record without manual entry. PACS integration connects radiology images to the RIS module and the patient record.
Yes. The ERP is custom-built on your contract — you receive the full source code and own it permanently. There are no per-user fees, no per-module subscriptions, and no vendor lock-in. You host it on your server or cloud account. Annual maintenance is optional and covers security updates, compliance standard updates, and enhancements.
