What is 40-trade friction?

Written By Terry Cornick

A modern commercial job site runs on roughly 40 specialist trades. Electrical, plumbing, HVAC, civil, steel, fit-out, crane, and thirty-odd more, each turning up with its own crew, its own schedule, its own paperwork, and increasingly its own software. Every one of them is a separate business. All of them have to behave like a single team.

The gap between those two facts is 40-trade friction: the daily cost of coordinating dozens of independent specialists who don't share a schedule, a system, or a source of truth.

It's the most expensive problem on your site, and almost nobody names it.

What it looks like on a Tuesday

The electrician can't rough-in until the plasterer clears the wall. The plasterer is waiting on a sign-off the site manager doesn't know is outstanding. He finds out at 6pm, by text. A crew stands around for half a day. The variation that came out of it gets discussed on the phone, never written down, and never makes it onto the invoice.

None of that is anyone's fault. It's what happens when 40 businesses coordinate through calls, texts, and a whiteboard in a demountable. One dropped handoff is an afternoon. Multiply it across 40 trades, every day, for the length of a build, and you have the single biggest drag on a commercial contractor's margin.

What it costs

Friction doesn't show up as a line item, which is exactly why it's so dangerous. It hides inside numbers you already accept as normal:

  • Margin leakage of 10-15%, lost to admin lag, double handling, and reconciliation.

  • Standing time when one trade waits on another that's running late or unbooked.

  • Rework when the left hand builds something the right hand has to open back up.

  • Unbilled variations that were agreed verbally and never captured.

You don't feel any single instance. You feel it at the end of the job, when the margin you quoted isn't the margin you banked.

Digitising was supposed to fix this. It made it worse.

Here's the part nobody wants to say out loud. The tech boom didn't remove 40-trade friction. It relocated it.

The average trade business now runs 6.2 digital platforms, up 20% year-on-year. But those platforms were bought one trade at a time, one problem at a time, and none of them were built to talk to each other. The friction that used to live on a whiteboard now lives in the gaps between six apps that don't sync. It's harder to see and harder to fix, because it's buried in exports, screenshots, and copy-paste.

And that's the half of the industry that went digital at all. Around 21% of trade businesses are still on pen and paper. So the typical commercial site now runs some trades on incompatible software and others on a paper docket, trying to build one building together. That is not progress. That is a new, more expensive kind of chaos.

Why it matters more right now

In a boom, you can absorb friction. Margins are fat enough to hide it. That era is over.

Australian contractors are in a pincer: a shortfall of 70,000 to 80,000 workers against national housing targets, sustained material cost pressure, and aggressive margin compression. FY2024-25 saw around 3,490 construction insolvencies, a decade high. When margins are this thin, the 10-15% you're leaking to friction isn't an annoyance. It's the difference between a viable firm and a statistic.

The businesses that scale from here won't be the ones with the best tradespeople. They'll be the ones who stop paying the friction tax.

What actually removes it

Not another standalone app. That's how you got 6.2 of them.

Removing 40-trade friction means treating the site as one connected system, across three layers:

  • Management – the software that coordinates the trades: scheduling, dispatch, and field-to-office comms that close the handoff gaps.

  • Muscle – the tools, hardware, and fleet that keep the physical work moving, tracked and accounted for.

  • Money – the fintech, payroll, and finance layer that stops margin leaking out through the cracks.

Get those three talking to each other and the friction doesn't just reduce. It largely disappears, because the handoffs that used to fail silently now happen inside a system that catches them.

That's the entire premise of TradieTech: one room, three pillars, built to show scaling trade businesses how the connected site actually works, so they can stop leaking margin to a problem they were never told had a name.

Now it does. It's called 40-trade friction. And it's beatable.
