Your Equipment Isn't Free — It's Just Invisible

In most construction, civil and technical services businesses, there's a reliable way to make a job look more profitable than it is: use your own equipment.

Not because owned plant is cheaper — often it isn't — but because of how it's accounted for.

The accounting quirk that distorts job margins

When a business hires plant externally, the hire invoice lands against the job. The cost is visible, allocated, and priced into the quote. Everyone can see what the machine cost the project.

When the business uses its own excavator, crane, truck or workshop equipment, the costs still exist — depreciation, maintenance, repairs, finance, insurance, registration — but they land in overhead, spread across the whole business. At job level, the machine appears free.

The bank account doesn't care about the difference. The job reports do.

Three decisions this distorts

1. Which jobs are actually profitable. A job that ran on owned plant will show a stronger margin than an identical job that ran on hires — not because it was delivered better, but because a real cost was routed around it. Management then draws conclusions about which types of work, clients or crews perform best, using numbers that were never comparable.

2. How jobs get priced. Estimators price what they can see. If owned plant carries no cost, quotes involving it drift downward — and the business ends up structurally underpricing exactly the work that uses its most capital-intensive assets. The equipment that cost the most to acquire becomes the reason margins erode.

3. Whether to own or hire. Fleet decisions — replace the machine, buy another, or move to hiring — need a genuine cost comparison. When owning shows up as zero at job level and hiring shows up at full rate, the comparison is rigged. Businesses over-invest in plant that never pays for itself, because nothing ever asked it to.

The fix: internal plant rates

The solution is straightforward and long-established in well-run contracting businesses: every significant piece of equipment carries an internal charge rate, and jobs get charged for using it — exactly as they would for an external hire.

Setting the rate properly means covering:

• Depreciation — the real consumption of the asset, not just the book figure

• Maintenance and repairs — averaged across the asset's life, including the expensive years

• Finance and holding costs — the money tied up in the machine has a cost

• Utilisation — the rate has to be recovered across realistic working hours, not theoretical ones. A machine used 600 hours a year needs a very different rate from one used 1,500.

Once rates are in place, jobs are charged for equipment hours the same way they're charged for labour hours. Job margins become comparable regardless of whose machine did the work. Quotes reflect true delivery cost. And the plant list starts answering a question most businesses have never put to it: is this machine earning its keep?

Nothing changes — and everything does

Introducing internal plant rates doesn't move a single dollar in or out of the business. It's a reallocation, not a cost. What changes is visibility: which jobs make money, which quotes are sound, and which assets deserve their place on the balance sheet.

That's the recurring theme in operationally complex businesses. The costs were always there. The question is whether the reporting lets you see them where decisions get made — at the job, before it's priced, not in an overhead line six months later.
