The challenges commercial teams face
Multi-site jobs with zero visibility
Commercial jobs span multiple sites, crews, and subcontractors. Without a central system, project managers are texting for status updates and building reports in Excel.
Job costing that doesn't handle complexity
Commercial jobs have layered cost structures — multiple subcontractors, equipment phasing, multi-tranche invoicing. Generic accounting tools weren't built for this.
Subcontractor management in spreadsheets
Rate cards in email threads. Subcontractor time tracked in a separate system. Change orders managed in Word. One platform should hold all of this.
