Excavation contractor CFO services: make every machine-hour pay

Every machine gets an hourly cost — and a job to justify it

The core discipline is an internal rate per machine-hour: ownership costs — depreciation, financing interest, insurance, storage — plus operating costs — fuel, tracks and wear parts, maintenance — divided over the hours the unit realistically works each year. Jobs get charged that internal rate for the hours they consume, which makes job margins real and turns idle iron into a visible loss instead of a quiet one. A 30-tonne excavator working 400 hours a year is a fundamentally different asset from the same machine working 1,200, even if both look identical on the balance sheet.

Utilization then answers the question owners argue about most — own or rent:

Bid pricing: unit rates with the risk written in

Excavation bids are won and lost on unit rates — per cubic metre moved, per metre of trench, per lift of granular placed — and a unit rate is only as good as the production assumption underneath it. We close the loop with job costing: bid quantities and rates compared to actuals by cost code on every job, so the next bid inherits real production data instead of optimism. Soil conditions, groundwater, rock, and disposal distance are risk items that belong in the rate or in the contract language, never absorbed in silence; fuel, a major input, gets escalation language on anything long. Standby deserves the same treatment: a machine mobilized to a stalled site earns nothing while its ownership clock keeps running, so standby terms belong in the contract before the delay, not in an argument after it.

Contract mechanics shape the cash behind the bid. Ontario Construction Act holdbacks keep 10% of billings out of reach until release, progress billing has to track earned quantities, and payments to subcontractors trigger T5018 reporting — plumbing our excavation bookkeeping service keeps straight alongside work-in-progress, so the margin you bid is the margin you can see.

Replacement cycles: sell before the machine decides for you

The replacement question mostly answers itself once two numbers are tracked per unit: repair cost per operating hour and days down. Both curves climb with age, and there is a window — typically as a major component rebuild approaches — where the resale market still pays well and the repair curve is about to steepen; that window is when you sell. Hour meters and telematics make the tracking nearly free. The discipline is reviewing the fleet ranking twice a year and planning disposals, instead of crisis-buying whatever the auction has the week a machine dies.

Where you buy matters as much as when. US auctions often price attractively in nominal terms, but the landed cost includes exchange, any duty, GST collected at the border, and transport home — arithmetic our excavation cross-border tax page walks through before the bidding starts, because a bargain that ignores the border usually is not one.

Financing the iron without strangling the cash

Finance, lease, or pay cash is a forecast question before it is a tax question. We model each purchase inside a rolling 13-week cash forecast that already carries loan payments, insurance renewals, and the winter trough, because the deduction schedule and the payment schedule never line up — CCA follows its own clock while principal payments consume cash with no deduction attached. Seasonal staffing sits in the same plan: operators laid off for winter need proper ROEs and a call-back plan, mechanics we handle through our excavation payroll page.

The end state is a fleet that earns its keep unit by unit, bids built on measured production, and a winter that was funded back in September. That is what a fractional CFO adds to a business where the capital sits in the yard.
