The NAC OS Fleet Logbook — a browser-based fleet operating system. QR scan-start shifts, meter reading capture, PM scheduling with OEM part numbers, operator timesheets, invoicing, AR aging, HST remittance, and CCA depreciation. Built around the CASE 580SN — ready for any machine.
NAC OS Fleet Logbook™ is a self-contained browser-based application — no installation, no Google account required, no subscription software. Data is stored locally in your browser. Works on any device. Deploy by hosting one HTML file.
QR codes per machine open the daily log instantly. OCR meter capture auto-fills hours from a photo. PM scheduling tracks every service interval by both hours and calendar days. Everything connects — daily logs feed timesheets, timesheets feed reports, service records feed the PM schedule.
The operator scans the QR code in the cab. The meter photo updates the hours. The daily log is complete before they leave the machine.
NAC OS Fleet Logbook™ — Design PrincipleBuilt for contractors who operate real machines on real job sites — not software designed for dispatchers at a desk.
Each machine has a QR code that opens the daily log directly. Operator scans from the cab — machine ID, date, and operator are pre-filled. No typing, no paper. Already live and tested.
Live & WorkingQR-start shifts per machine. Operator scans the cab QR code, enters meter reading, and the log entry is created automatically. One URL per machine — no app install required.
Live & WorkingPre-use checks (oil, hydraulics, transmission, DEF, greasing, tires, leaks, warning lights, cab, attachments), hours, fuel, materials, overall condition, corrective actions, supervisor sign-off, operator and mechanic signatures.
Full Capture13 service items pre-configured for the CASE 580SN — dual-interval scheduling by both engine hours and calendar days. Auto-status flags: OK, DUE SOON, OVERDUE. Service alerts tab updates automatically.
Dual-IntervalTimesheets linked directly to daily equipment log entries. Task category, billable flag, job/property, and linked daily row number — labour cost and billing visibility built into the same system as machine hours.
Linked to LogHomeowner/contractor approval log for billable work. Request date, work category, estimated vs final costs, approval status, approval signatures. Full audit trail for every approved, pending, and rejected work order.
Audit TrailFleet-level KPIs: machines registered, total hours, total fuel, maintenance spend, overdue items. Per-machine dashboard: daily entries, hours by date chart, service status summary. Live session view for current shift.
Fleet + Per-MachineMonthly summary auto-generated from daily log entries — entries count, hours used, fuel added, maintenance spend. One row per month, full year visible. No manual aggregation required.
Auto-GeneratedMachine ID dropdowns throughout — add machines to the Fleet Assets registry and every sheet follows. Per-machine QR codes, independent PM schedules, separate service histories. Built for fleets, not just one unit.
