The Operational Problem

Field technicians and crew foremen had to fill out paper job tickets at the end of exhausting 10-hour workdays. Paper notes were frequently illegible, lost, or submitted days late, causing billing delays, missed change-order charges, and payroll discrepancies.

The Turning Point

Management spent every weekend manually deciphering paper field notes and typing data into accounting software instead of managing active job sites.

The System Built by Promptful

Promptful deployed a lightweight mobile web application called 'RMI Job Tracker'. Crew members simply tap a button on their phone and speak naturally about completed work, materials used, and change orders. An AI speech-to-text engine formats the recording into structured daily field logs, logs crew hours, and updates job cost records automatically.

Workflow Pipeline Comparison

Before (Legacy Manual)
  • Foremen write paper field notes in truck at end of shift
  • Paper tickets collected weekly at central office
  • Admin staff manually types illegible notes into QuickBooks
  • Change orders forgotten or disputed by homeowners
After (Promptful Engine)
  • Foreman records 30-second audio note on smartphone
  • AI transcribes, cleans, and structures data variables
  • Job record updated instantly with labor hours & materials
  • Invoice & change order generated same-day

"Our guys hate typing on phones, but they don't mind speaking for 30 seconds after a job. Promptful's system captured over $14,000 in change orders we would have previously missed."
