Built around the friction
Less chasing details. More control over the work.
Know which technician is where and what comes next.
Move work through a shared dispatch-to-field view.
Turn diagnosis into customer-ready work.
Carry the job into estimates and invoices without rebuilding every detail.
Keep callbacks, reviews, and commissions visible.
Replace scattered notes and spreadsheets with an operational record.
Built from real field work.
Appliance-repair depth. A broader field-service platform.
City Master Assist grew from the daily workflow of a real appliance repair operation: booking customers, dispatching technicians, tracking models and symptoms, sending estimates and invoices, recording payments, and managing commissions.
That same operating depth now adapts to HVAC, refrigeration, plumbing, electrical, property maintenance, equipment repair, and other mobile service teams.
