The challenge

Where the client started

A growing residential contractor was running projects from spreadsheets, WhatsApp threads, and paper checklists. Site supervisors lost hours reconciling progress with head office, and clients had no trustworthy view of timelines or spend.

The solution

What Duple built

  • Executive dashboard with portfolio-wide KPIs and risk flags
  • Site supervisor mobile views for daily logs, photos, and snag lists
  • Crew and subcontractor scheduling with conflict detection
  • Material delivery tracking linked to milestones
  • Client portal with milestone approvals and document vault
  • Automated weekly PDF reports for stakeholders
  • Role-based access for finance, PM, and field roles
