How it runs

How a construction job runs, end to end.

Lead→Site Survey→Estimate→Contract→Material Order→Crew Schedule→Timesheets→Progress Bill→Final Invoice

The estimate becomes the job budget, and every purchase, hour and subcontract is costed against it.

Projects and tasksPhases, milestones and task lists per job, with the crew and supervisor assigned.
