## Frequently asked questions

### How can an accountant help structure the mileage reimbursement process?

An accountant can define which fields must appear on receipts to ensure deductibility, advise on accounting classification, suggest a per-km rate review cadence, map reclassification risks, and structure monthly reports that let finance identify cost trends by area or cost center.

### What minimum data should the mileage reimbursement process capture to become a management dataset?

To transform reimbursement into management data, the process must capture: employee, date, origin, destination, commercial purpose, distance, rate applied, amount, approver, and cost center. With these standardized fields, finance can compare cost by area, identify frequent routes, detect exceptions, and support policy reviews.
