Built specifically for specialty contractors and self-perform general contractors managing complex field operations, SmartBarrel eliminates time theft, reduces payroll processing time, and provides the verified labor data needed for job costing, T&M billing, and compliance reporting. The Time Tracking Problem in Construction Most construction contractors still rely on manual timesheets, crew time entry, or mobile apps that fail in real field conditions. Foremen spend hours reconstructing timesheets from memory. Workers forget to clock in or can't access systems without WiFi. Buddy punching costs thousands per worker annually. And when it's time to bill T&M hours or defend labor costs, contractors lack the documentation to back up their numbers. SmartBarrel solves this by capturing verified time at the point of work—no manual entry, no guessing, no disputes. How SmartBarrel Works Hardware Built for Jobsites The TimeClock 4.0 biometric time clock lives on your jobsite—magnetic mount, weatherproof, powered by solar or electricity, with built-in LTE connectivity. Workers walk up, enter their phone number, scan their face, and they're clocked in. No training required. No WiFi dependency. No excuses. The facial verification system uses AI to compare each scan against previous photos—not facial recognition that identifies who you are, but verification that confirms you're the same person. The system self-learns workers automatically—no photoshoot required. Real-Time Data Flow Every punch flows instantly to the centralized dashboard. Supervisors see live headcount across all jobsites, review punches, assign cost codes, and approve hours—all from one screen. Automatic lunch break deductions, rounding rules, and overtime calculations happen in the background. When you're ready to run payroll, your verified timesheets are already built.
