Trip registration the way the Belastingdienst likes it.

Log every trip with start and end odometer readings, classify business or private, and export an Excel that matches the Dutch official format. Compliant by default, painless by design.

Log a trip with start and end address.

Every trip gets its start and end address and odometer readings. Byna calculates the kilometres as end minus start, so you never type a total.

  • Start and end address per trip
  • Kilometres from the odometer readings
  • Business or private per trip

Keep every trip in one log.

Each car has its own reimbursement rate and trip numbering. Private kilometres never count for the reimbursement, and a trip with a deviation reason stays documented for the auditor.

  • Own rate and trip numbering per car
  • No reimbursement on private kilometres
  • Flag a trip with a deviation reason

Export your trips to Excel.

One click gives you a spreadsheet that matches what your employer or the tax office expects. Every new trip starts at the end reading of the last one, so the readings line up.

  • Excel in the official Dutch format
  • Start reading carried over from the last trip
  • Ready for your employer or accountant

What you can do with it

Per-vehicle rates

Different cars, different reimbursement rates. Byna applies the right one automatically.

Business, commute or private

Pick the type per trip. Private kilometres never count for the reimbursement.

Auto km calculation

Eind-km minus begin-km, zero typing of totals. Byna catches mistakes before you submit.

Start and end addresses

Captured per trip, kept on the record for your employer or accountant.

Exceptional routes

Flag a trip with a deviation reason. Documented for the auditor.

Excel export

One click to a spreadsheet that matches what your employer or the tax office expects.

How it works

Stop guessing in March.

When you wait until tax season, you forget. Byna lets you log a trip in 15 seconds from your phone, the moment it ends. By March, your year is already done.

Common questions
