Every dollar traces to an event.

Fuel fills and part issues post themselves into one cost ledger the moment they happen. Manual entries cover the rest. The result: a machine's true cost of ownership, defensible line by line.

The Solmex cost ledger: one row per financial event with its date, category, source, the machine it belongs to, the description and the amount.
Fuel entries and parts issues post their own lines here as they happen. Nothing is re-keyed at month end.

Costs & fuel

Nobody keys a cost twice.

Log a fuel fill, issue a part — the ledger row writes itself, tied to the machine and the work order. Re-post the same transaction and it updates in place instead of duplicating. Accountants call that idempotent; we call it correct.

Fuel that files itself

Every fill-up is logged per machine — litres, station, meter reading — and lands in the cost ledger the same second. Burn rates per machine come free.

Cost of ownership, per machine

Open any machine and read its money: lifetime, this year, this month, last 30 days, by category. The keep-or-replace argument finally has numbers behind it.

Void, never delete

Wrong entry? It's voided with a reason and kept — the financial record never loses a row. Every change sits on an activity timeline an auditor can walk.

Questions about costs and fuel

01Where do the cost figures come from?

From the operational records themselves. A fuel entry and a warehouse issue each post their own line to a single cost ledger as they happen, so cost per machine is a consequence of the work being recorded rather than a separate exercise somebody does at month end.

02Can Solmex tell us the cost per operating hour?

Yes, for any machine that has meter readings, because operating hours come from meter history rather than from the fuel rows. A machine with fewer than two readings in the period is reported as unmeasured rather than being given a figure, since a machine that burned fuel with no recorded hours is exactly the one a manager should see.

03How does Solmex know a fuel entry is wrong?

It compares each fill against that machine's own median consumption rather than against a fleet or manufacturer figure, because a water truck and an excavator share no vocabulary on litres per hour. A fill well above or well below the machine's own baseline is held for confirmation with the deviation stated, and a fill larger than the machine's stated tank is impossible by arithmetic rather than by threshold.

04Is there a fuel report for management?

Yes, a typeset A3 fuel management report: consumption and spend, efficiency against the fleet's own group medians, a ranked equipment table, a station summary, an exception register and a projection. Where a figure would need evidence Solmex does not record, such as a receipt image or a GPS trace, the report names the absence instead of manufacturing the number.
