Old receipts pile up — and they distort your numbers
If you've been stuffing fuel receipts in the glovebox, entering them all today makes your car stats lie. FinMan calculates consumption and real cost-per-kilometer from the sequence of refuels and odometer readings. Ten receipts dumped on the same date compress months of driving into one day, and the math breaks.
Enter each refuel with its real date
The fix is simple: give every receipt the date it actually happened. That way litres, price and mileage fall in the correct order and the differences between fill-ups compute properly.
- Send the fuel-receipt or dashboard photo to the bot. AI reads litres, price, total, station and, from an odometer photo, your mileage.
- Before saving, use /historical to apply the receipt's real date to the submitted photos.
- Repeat for each receipt, working oldest to newest so odometer readings climb in order.
Tip: Do them in chronological order. If a later reading somehow shows fewer kilometers than an earlier one, you've mixed up dates — fix it before the totals go sideways.
Why order matters for cost-per-km
Cost-per-kilometer is fuel plus repairs, maintenance and other car costs spread across the distance you actually drove. FinMan needs to know which mileage came before which to split those costs into real intervals. Backdating keeps each period honest instead of blending a quiet month with a road-trip month.
A quick monthly habit beats a yearly cleanup
- Snap the receipt at the pump — the photo flow fills the details in seconds.
- Log your odometer at the same time so mileage and litres pair up cleanly.
- If you forget, that's fine — /historical lets you catch up later without corrupting the timeline.
Running more than one vehicle? Each car keeps its own refuel and odometer history, so backdating one car's receipts won't touch another's stats.
