ClockShark started life inside a family-owned construction business in Chico, California, and has grown into a 9,500-customer time-tracking platform trusted by 100,000+ field workers. For HVAC contractors, the appeal is simple: techs clock in from their phones with GPS-verified locations, switch between jobs and tasks without clocking out, and the office gets clean, approved timesheets ready to push into QuickBooks, Gusto, ADP, or Paychex. The app is intentionally lightweight, which makes rollout to a 10-tech shop take hours rather than weeks.

Beyond time, ClockShark includes drag-and-drop scheduling, job costing by task and cost code, customizable reporting, and a CrewClock feature for foremen to clock in a whole crew at once - useful on larger HVAC install jobs. Managers can set geofences so time only counts when techs are actually on site, and the app's offline mode captures punches even when coverage drops in mechanical rooms or basements. Owners use ClockShark to see labor cost per job in near-real-time and spot the installs or service agreements that are running over.

ClockShark is not a payroll engine; it integrates with QuickBooks Online, QuickBooks Desktop, Gusto, ADP, Paychex, Xero, MYOB, Sage, and Zapier. Pricing is transparent and sits in the mid-range: a monthly base fee ($40-60) plus $9-11 per active user depending on tier. For HVAC shops that want something more robust than a free app but don't need Arcoro-level HR depth, ClockShark is a common sweet-spot pick.
