HCool FSM — Field Service Management Platform
H-Cool Aircon
H-Cool Aircon's air-conditioning service business ran on paper job sheets and phone calls, with no central system to schedule technicians, track contracts, or generate invoices across a growing client base.
Results
Challenge
H-Cool Aircon's team coordinated technician visits, maintenance contracts, and client servicing manually — job assignments were tracked over calls and paper reports, contract renewals were easy to miss, and invoicing required rekeying job data into accounting software by hand. There was no live view of which technician was where, no digital service reports, and no way for admins or clients to see job status in real time.
Our Solution
We built HCool FSM, a full field service management platform with a NestJS/PostgreSQL backend and a React (Refine) admin dashboard paired with a dedicated mobile-optimized technician interface. The system covers the entire service lifecycle: client and property management (with contacts, addresses, and notes), maintenance contracts with repeat scheduling, service and task templates, a visual daily/weekly/monthly scheduling board for dispatching technicians, digital service reports with photo uploads and customer signatures captured on-site, and direct Xero integration to auto-generate invoices from completed jobs — removing manual re-entry entirely.
Outcome
H-Cool Aircon moved from paper-based, phone-coordinated operations to a single connected system covering scheduling, servicing, and billing. Admins get a real-time schedule board and dashboard visibility across all contracts and technicians, technicians get a mobile flow to view assigned jobs, complete on-site reports, and capture signatures, and completed services now flow straight into Xero for invoicing — cutting the admin overhead that used to follow every job.
Key Features
Benefits
Zero double-entry billing
Direct Xero sync means completed service reports convert straight into invoices, eliminating the manual rekeying that used to delay billing by days.
Real-time technician visibility
The scheduling board gives dispatchers a live view of technician availability and job load, replacing phone-call coordination with a single glanceable timeline.
Paperless service reports
Technicians capture photos and customer signatures directly on mobile, so reports are complete, timestamped, and stored the moment a job finishes — no lost paperwork.
