Nova Aesthetics POS
Offline-First Clinical & Financial Management System
Nova Aesthetics POS is an offline-first desktop clinic point-of-sale, patient billing, and financial ledger system built for a medical practice in Islamabad. It was architected and delivered end to end as a commercial client engagement.
Challenge
The clinic needed reliable billing and financial records in an environment where connectivity is not guaranteed. The system had to keep working offline, reconcile records when a connection returned, and remain simple enough for non-technical staff to use during a busy clinic day.
Architecture
Electron packages a React interface with a local SQLite database and Node.js services. Writes land locally first, so billing and ledgers remain available during outages; a synchronization layer reconciles records when connectivity returns. The desktop bundle avoids browser dependency and keeps patient and financial data on the machine.
Key decisions
Local-first writes
SQLite is the source of truth during outages, so a dropped connection never blocks a patient checkout or a ledger entry.
Electron for a controlled desktop runtime
A packaged desktop app gives predictable file and system access without asking clinic staff to manage a browser-based environment.
An explicit sync boundary
Offline records are reconciled through a dedicated sync layer rather than scattering connectivity checks across the UI.
Billing and ledger in one surface
Keeping point-of-sale, patient billing, and financial records together reduces the number of tools staff need to learn.
