Field notes
The workflow starts with plan sheets: users set a scale from a known dimension, measure runs or count fixtures, and send those quantities into an estimate. The page says each sheet can have its own scale, and that jobs keep estimates, work orders, and invoices attached to the same record. It also describes technician access limited to assigned work orders and personal hours, with payroll totals exportable as CSV.
