Overview/ 01
One platform for the whole hospital
ZenHosp is a complete hospital ERP. It brings appointments, clinical records, diagnostics, pharmacy, billing, insurance and HR & payroll into one system — so clinical and operational teams work from the same data.
Exarth designed and built ZenHosp end to end — a modular platform where every department, from the front desk to the lab to finance, gets a focused workspace while leadership sees real-time hospital performance.

Challenge & solution
Disconnected systems, or one hospital ERP
The hospital ran on disconnected systems — paper charts, a separate pharmacy POS and manual billing — with no single patient record.
- Paper records
- Separate systems
- Manual billing
Beds · Patient flow
Manual board — Bed availability was tracked on a whiteboard, never quite accurate.
Clinical · Records
Paper charts — Doctors relied on paper charts that were easy to lose or misread.
Diagnostics · Lab & imaging
Manual results — Lab, radiology and pathology results were handed over manually.
No core
No shared platform
Fragmented systems
ManyDisjoint tools0Single record
Pharmacy · POS
Separate POS — The pharmacy ran on a separate POS disconnected from prescriptions.
Billing · Finance
Manual bills — Patient charges were tallied by hand, causing billing errors.
Insurance · Claims
Slow claims — Insurance claims were processed slowly across disconnected tools.
HR & Payroll · Staff
Paper HR — Staff, payroll and subscriptions were managed outside the system.
