Challenge
The firm runs 20-30 sites concurrently. HQ chased status by phone and LINE. When customers asked "how's my site?", staff couldn't answer immediately—straining trust.
Approach
Built a simple "photo + one-line comment + status" posting flow site-by-site, designed to be usable by tradesmen. HQ sees every site's latest activity in a single timeline.
Implementation
Three taps from camera to post. Supabase Storage auto-handles photo uploads, and time-limited tokenized links let customers see their site's progress directly.
Results
Status-check calls and LINE messages dropped 85%. Customer inquiries are answered within an hour, strengthening trust. Month-end billing prep fell 60% since photos and progress already serve as billing evidence.
