Drivers who use their own vehicle for work often need to keep a record of the journeys they make. Whether the purpose is an employer claim, a self-employed return or a simple personal review, the same problem appears: trips are made quickly, and the details fade. A mileage log written weeks later is rarely accurate. A steady system that captures each journey at the time it happens is far more reliable, and it protects you if your records are ever questioned.
Understand what records are usually needed
Before choosing a method, check what information your employer, accountant or tax authority expects. Commonly, a log includes the date, the start and end locations, the purpose of the journey and the distance travelled. Some organisations also ask for the vehicle registration or a note of which client was visited. Rules differ between countries and between employers, so confirm the requirements in writing. A qualified accountant or tax adviser can explain how the rules apply to your situation.
Choose a method you will actually use
The best logging method is the one that fits into your routine. Some drivers prefer a paper notebook kept in the glovebox, which is quick and needs no signal. Others use a spreadsheet on their phone or a dedicated app that records trips automatically. Automatic tools save effort but need checking, because they can record private journeys as business trips if you do not review them. Whatever you choose, make sure it is simple enough to update at the end of each working day.
Many drivers find a short routine effective:
1. Note the date and the starting point before setting off.
2. Record the destination and purpose as soon as you arrive.
3. Write the odometer reading at the start and end of each day.
4. Review the week’s entries every Friday and fill any gaps.
Separate business and private journeys
Mixing personal and work trips in the same log is a common source of confusion. Decide in advance how you will mark private journeys, such as a simple code or a separate column, and apply it consistently. Trips that combine both purposes need a clear explanation. Keeping the distinction clean protects your claim and makes the record easier to explain if anyone asks questions about a particular day.
Keep supporting evidence together
A mileage log is strongest when it is backed by other records. Keep parking receipts, toll statements, meeting invitations and client correspondence in the same folder as the log. These documents show that a visit happened and help confirm the purpose of the journey. Store digital copies in a safe place and back them up, because paper receipts fade and phones can be lost. If you are unsure which documents are needed, ask your finance team early.
Avoid common mistakes
Several errors appear frequently in mileage records. People often forget to log short detours, round numbers are used instead of actual readings, or the same trip is recorded twice by different methods. Another mistake is waiting until the end of the year to reconstruct the entries from memory. Set a fixed weekly review to catch these problems early. If you discover an error, correct it openly and note the reason, rather than quietly changing the figures.

Records also need protecting from loss. Photograph the odometer at the start of the year and keep a copy in a secure place. If you use a paper log, store completed pages in a folder rather than leaving them loose in the car, where they can be damaged by heat, damp or spilled drinks. Back up digital entries regularly to a second location, and check that the file opens correctly after each backup. These habits are simple, yet they prevent the frustrating situation of reconstructing a year of journeys from memory because a single device was lost or a notebook was left in the rain. It is also wise to keep one simple note in the folder explaining how the log is kept, so that anyone reviewing it understands the method you used.
Good mileage records are built gradually. A simple daily habit, a weekly review and a folder of supporting evidence make the year-end process far less stressful. When the records are clear and complete, you can focus on the work itself rather than worrying about what happened on a journey weeks earlier.
