Case study
Automated Utility Billing & Financial Reconciliation Platform
Executive summary
A comprehensive full-stack platform designed to automate complex utility billing, dynamic tariff management, and multi-client financial reconciliation.
The problem
Manual billing complexity
Managing utility billing across multiple clients with variable tariffs (fixed and dynamic) creates heavy administrative overhead and frequent human error.
Accounting disconnect
Poor synchronization between operational billing and accounting tools (such as Xero) causes reconciliation gaps and audit risks.
Static pricing limitations
Legacy systems struggle to support CPI-based adjustments and sliding-scale pricing needed for accurate long-term contracts.
Inventory inefficiency
In specialized environments such as pharmacies, fragmented stock-on-hand and billing workflows reduce operational clarity.
The solution
Automated invoicing engine
A centralized workflow generates and tracks auditable invoices to reduce manual effort and improve accuracy.
Granular tariff control
A multi-tier pricing engine supports default, fixed, and client-specific overrides with automated CPI and sliding-scale adjustments.
Deep accounting integration
Seamless integration with Xero and GoodX supports automated age analysis by invoice date and smoother finance handoffs.
High-volume data pipelines
Robust CSV ingestion workflows process bulk meter data (Kamstrup) and pharmacy stock levels efficiently.
Integrated pharmacy operations
Dedicated modules manage stock-on-hand, par levels, and inventory-linked operational data in one workflow.
Technical deep-dive (impact)
Domain-driven backend. The Node.js and TypeScript API follows a modular domain-driven design so the platform can grow cleanly as integrations such as Xero, GoodX, and Kamstrup expand.
Scalable data layer. A PostgreSQL schema was designed for historical record tracking and variance reporting, preserving auditability for strict financial control.
Performance-first frontend. React with Material UI and route-level feature separation enables operations teams to work across large datasets without interface lag.
Automated background processing. Redis-backed task execution ensures bulk uploads and complex reports run asynchronously without blocking the main API thread.
