Challenge

A real property renovation company needed to manage customer property services and its specialised work in one place. The path from an on-site damage estimate to a finished services invoice was slow and manual — field teams, customer details, job status, and billing all lived in separate tools and paperwork.

Key challenges:

Slow estimate-to-invoice cycle for property renovation jobs
Customer and property service data scattered across disconnected tools
No single mobile tool for field teams to manage jobs on site
Manual coordination between estimates, scheduling, and billing
Customer experience suffered from delays and poor visibility

Solution

We built a highly customisable CRM mobile app in Flutter — one tool for managing customers, property services, and the full workflow from damage estimate to services invoice, on both iOS and Android.
