The simplest mileage system is usually the one you use while the journey is still fresh in your mind.
If you leave your mileage until the end of the week or month, it becomes much easier to forget short journeys, locations and the reason you travelled.
Why recording mileage as you go matters
A supplier visit, client meeting or site journey can be easy to remember today and surprisingly difficult to reconstruct several weeks later.
For 2026-27, 20 forgotten business miles at the 55p car and van rate represents £11 of mileage allowance.
The aim is not simply to choose the most sophisticated app. It is to use a method that makes accurate recording easy enough to become part of your normal routine.
Four ways to track work mileage on your phone
| Method | Effort | Strength | Trade-off |
|---|---|---|---|
| Notes app | Type each journey | Free and already on your phone | Easy to forget and you must total everything yourself |
| Spreadsheet | Enter each journey | Structured and easy to total | Can be awkward on a small screen and is often completed later |
| Automatic GPS tracker | Low effort during the drive | Automatic trip detection | Requires journey review and uses background location tracking |
| Odometer-photo method | Start and finish each journey | Visible supporting mileage evidence without continuous GPS | You need to remember to record the journey yourself |
What should you record for each business journey?
Whichever method you use, keep enough information to understand the journey later.
When the journey took place
Why you travelled
Where the journey began
Where the journey finished
The business miles recorded
Where useful, keep the vehicle and supporting journey information together
Which method suits different working patterns?
You make occasional business journeys
A simple manual or odometer-based method may be enough and keeps the process easy to control.
You drive all day and make many short stops
Automatic GPS tracking can reduce the number of actions you need to take during the day.
You do not want continuous location tracking
A start-and-finish mileage method allows you to record the journey only when you choose.
You want supporting evidence with each journey
An odometer-photo approach can keep visible readings alongside the mileage record.
You need reports for your accountant or records
Choose a method that can turn your journeys into a clear downloadable mileage report rather than leaving you to rebuild the information later.

Frequently asked questions
Can I track business mileage without GPS?
Yes. You can use notes, spreadsheets, manual mileage records or an odometer-based method. Continuous GPS is only one way of recording business journeys.
What should I record for each journey?
A useful mileage record should include the date, business purpose, start and end locations and the business miles travelled. Check current HMRC guidance for the requirements that apply to your circumstances.
Does tracking mileage drain my phone battery?
Background GPS tracking can use more battery because it may run while you travel. A start-and-finish method such as odometer-photo logging only uses the phone when you actively record the journey.
Can I use Going A2B on more than one device?
Yes. Going A2B is browser-based, so you can sign in from your phone, tablet or computer and access the same journey records.
