Trip sheets, fuel and settlements: where fleet margin leaks
A fleet knows its revenue precisely — the invoice says so. It knows its cost approximately, weeks later, when the diesel bills, the driver advances and the workshop entries have all been posted. The gap between precise revenue and approximate cost is where the margin goes.

Cost the trip, not the month
Monthly cost reporting tells you the fleet spent a certain amount on fuel. Trip-level costing tells you that a particular route, with a particular vehicle and driver, loses money every time it runs.
The inputs are all captured anyway — they are just captured against the wrong object. Fuel against the trip, tolls against the trip, driver batta against the trip, and a share of fixed cost per running day.
Fuel is where the arguments live
Mileage varies by load, route, terrain and driving. Any single figure is wrong, which is what makes fuel theft so easy to hide inside natural variation.
The signal is not a number, it is a distribution. The same vehicle on the same route with the same load, over twenty trips, has a normal range. What matters is the trip that sits outside it, and how quickly anyone notices.
- Fuel entries tied to a trip and an odometer reading, not to a date.
- Vehicle-and-route baselines rather than a fleet-wide target.
- Exception alerts within days, not a monthly mileage report.
- Tank-level data where sensors exist, reconciled against slips where they do not.
Driver settlement is an account, not an envelope
Advances for diesel, tolls, loading charges and food, adjusted against trip earnings, less deductions for damage or shortage. Most fleets run this in a notebook, which means the driver and the office each maintain their own version.
Running it as a proper ledger, visible to both, removes the monthly negotiation and — in operators we work with — reduces driver turnover, because drivers trust arithmetic they can see.
Detention and demurrage are earned, not remembered
Waiting time at loading and unloading is billable under most contracts and unbilled in most fleets, because proving it requires a timestamped record that nobody was collecting.
In-gate and out-gate captured at the point of the event, with a photo, turns a contractual right into recovered revenue. It is often the single fastest margin improvement available to a mid-sized fleet.
