Questions, answered.
Which plan includes the business logbook?
Business. It includes the business and private logbook, the country profiles and the fleet tools, also for a single company car.
Which countries' rules does the logbook follow?
Czechia, Germany, Austria, the Netherlands, Poland and Slovakia, each with the fields and checks its tax rules ask for.
Will my accountant accept the logbook?
Viametry records the fields its country profiles cover and points out gaps. It doesn't guarantee tax acceptance or decide your deductions; your accountant reviews the records.
What happens to private journeys in a company car?
Drivers can use private mode, working hours apply, and drivers can see what is recorded. What managers see depends on your company policy and their role.
How the logbook works day to day
What is recorded for you
Date, time, start and destination, distance, odometer, car and driver come from the car. Drives are grouped into trips, so a day of client visits is a few lines, not dozens.
What you add
- Business or private, per trip or per single drive.
- The purpose of each business trip: the client or the reason. A vague purpose such as "business trip" is what tax offices question most.
- The place by hand, when a business drive has no recorded place.
Every Monday, and on the 1st for the month just ended, Viametry can remind you of trips still missing business or private, or a purpose.
A month, worked through
Jana drives a company Model Y. In September she makes 38 drives, which Viametry groups into 21 trips. The Monday reminder lists the four she has not marked yet. She marks the client visits as business with the client's name, and the drive to her children's school as private.
On 1 October she exports September as a PDF for her accountant, with the Excel file for the figures. Each export carries a checksum that shows whether the records were changed afterwards.
Drivers and private use
- Private mode, on cars that may be used privately: no route and no addresses are stored, only distance, time, energy and cost.
- A trip marked private afterwards loses its route and places.
- A driver's saved home shows to others as "Driver's home", without the address.
- Working hours: outside them, on cars with private use, no location is stored. Owners and managers do not see the details of private trips.
Exports for the accountant
- Logbook as PDF, CSV or Excel, in your country's language unless you choose another.
- Accounting package: a fleet summary plus a logbook sheet per car.
- Fleet report, costs by cost centre, expenses and home-charging reimbursements.
- After a subscription ends you can still sign in and export everything until the end of the following calendar year.
Limits
- The country profiles are a reference, not tax advice: your accountant decides what your records must contain.
- Viametry does not file anything with the tax office.
- Business or private and the purpose are yours to set; Viametry does not guess them.
- The route of a private trip is deleted, so it cannot be shown later.
