Pricing from First Principles (and Why It Matters)

Pricing from first principles means building your price from the ground up.

That includes labour, plant, materials, preliminaries, overhead, profit, and sometimes risk. Everything is broken down clearly before you submit anything to the client.

You can still convert this into rates if needed. But behind those rates, you know exactly what it will take to deliver the job.

This is where most subcontractors fall short.

They submit a price, but they don’t have a clear build-up behind it. Which means when the job starts, they are relying on instinct instead of information.

And in the current market, that’s a problem.

If you’re not pricing like this, you are guessing.

What changes when you price this way

When you build your price properly, you get control back.

You can track labour hours against what you allowed.
You can see when plant hire runs over.
You can spot material increases early.

And most importantly, you can act on it.

If something changes, you can push a variation with confidence because you know your numbers.

If you’ve made a mistake, you can see it clearly and not repeat it on the next job.

That feedback loop only exists if your estimate is solid from the start.

Why this matters now

Margins are tighter, cashflow is under pressure and projects are less forgiving.

That means you need visibility early, not after things have gone wrong.

First Principles pricing gives you that visibility.

It won’t stop problems from happening.

But it will make them visible sooner, and easier to deal with.
