Explore Fleet ManagementRosenberger TelematicsDigital Logbook
Your tax-compliant logbook,
automated.
Whether a company car used privately or a pure business trip, Commander records every drive automatically from GPS data, for cars, vans and light commercial vehicles. No driver forgets an entry, and every export holds up to a tax audit.
The challenge
Paper logbooks fail audits, and driver discipline alone is never enough.
Austrian and German tax authorities have tightened logbook scrutiny. A single missed entry, a smudged date, or an unresolved dispute over who drove which vehicle is all it takes for the entire logbook to be disregarded, and the flat-rate 1% tax calculation to apply instead.
Missed entries invalidate everything
A single forgotten entry after a long shift is enough for tax authorities to reject the entire logbook and impose the punitive flat-rate 1% calculation, erasing any benefit of keeping records at all.
Multi-driver vehicles create disputes
When a vehicle is shared across several drivers, matching trips to the right person becomes guesswork. Disputed entries do not survive an audit, and manual reconciliation scales badly across a fleet.
Retroactive records are non-compliant
German and Austrian tax law requires entries to be contemporaneous and forgery-proof. Completing or correcting records after the fact is treated as non-compliance, regardless of how accurate the data might be.
Sachbezug calculations are error-prone
Without precise private-mileage data, the benefit-in-kind (Sachbezug) calculation defaults to the flat rate. Drivers end up taxed on fictitious usage rather than actual private kilometres, costing them money unnecessarily.
GPS data. Automatic entries. Audit-ready.
Two use cases, one solution: the tax-relevant logbook for privately used company cars, and gapless documentation of pure business trips with cost-center allocation. Commander's digital logbook module records every trip from the moment the ignition fires, start time, end time, start location, end location, distance. No driver input required for the base record. No gaps. No disputes. Drivers classify trips as business, private, or commute in seconds; private routes stay private. Every export is structured for Austrian and German tax requirements, ready at any time. Hardware, SIM connectivity, installation and the Commander software all come from a single source.
Automatic trip recording via GPS
Every journey captured automatically, start time, end time, start location, end location, and distance. The record exists before the driver leaves the vehicle. No entry is ever missed because the system does not rely on driver memory.
Driver classification: business, private, commute
Drivers classify trips via the R-DRIVE companion app or a vehicle-mounted multiswitch. Private trip routes and location data are never visible to fleet managers or administrators, only the driver sees them. Classification is frictionless and GDPR-compliant by design.
Tax-compliant export formats
Logbook exports generated in PDF and Excel formats structured for Austrian and German tax declaration requirements, with a complete audit trail demonstrating contemporaneous, unaltered, complete records. Ready at any time, not just at year-end.
Sachbezug calculation support
Commander calculates the private-use percentage from classified trip data, the figure your tax adviser needs to determine benefit-in-kind liability. Precise private mileage data means drivers pay tax on actual use, not a punitive flat rate.
Multi-vehicle and multi-driver support
Driver identification handled automatically via the R-DRIVE app or driver tokens. A vehicle shared across multiple drivers produces a complete, correctly attributed record for each, no manual reconciliation, no disputed entries, any fleet size.
One platform for mixed and large fleets
The logbook is a module of Commander, not a separate system. The same platform manages trucks with tachograph, construction machines via ISO 15143-3, and pool vehicles. Operators running cars, trucks and machines together control everything centrally and by role, at any fleet size.
How it works
From ignition to export, in three steps.
A device captures, the driver classifies, Commander exports. An audit-proof logbook needs nothing more.
The device captures every trip
A Rosenberger OBU or an existing OEM data stream captures every trip automatically, start, destination, time and distance. No manual entry.
The driver classifies and completes
Business, private or commute in one tap, via the R-DRIVE app or the in-vehicle multiswitch. Add the trip reason, edit, split or merge trips, in R-DRIVE or the web app.
Tax-compliant export
Export as PDF or Excel with a complete audit trail, structured for Austrian and German tax requirements. Available any time, not just at year-end.
