Material Shortages and Supply Chain Delays — How Australian Tradies Can Keep Jobs Moving When You Can't Get the Gear

If you've ordered a switchboard, a roll of cable, a batch of pipes, or just about anything with a semiconductor in it anytime in the last couple of years — you know the feeling. That sinking moment when your supplier says "not in stock, mate, and I can't tell you when."

It's not 2021 anymore. The COVID supply chain chaos is old news. But here's the thing tradies are figuring out the hard way: the disruptions didn't go away. They just changed shape. We've gone from "everything is out of stock" to "some things are always out of stock, and nobody tells you until you need it." Manufacturing lead times are stretched. Freight routes are still unpredictable. And local distributors are running leaner inventory than ever because nobody wants to sit on thousands of dollars of stock that might sit on a shelf for six months.

So you're on a job, the customer's keen, you've booked the crew — and suddenly the key material has a 12-week lead time. What do you do? You can't just fold the business because the supply chain said no. You need a system. Here's how to keep jobs moving when the stuff you need is nowhere to be found.

The first mistake most tradies make is treating supply chain delays like a surprise every single time. "I ordered that two days ago, it should be here" — said every tradie who's now three weeks behind schedule.

Stop treating supply chain as reactive. Sit down once a quarter and map out the materials that consistently cause you grief. For electricians, it's often DBs, RCBOs, switchgear, and specific cable sizes. For plumbers, it's certain fittings, PEX fittings, specific tapware, and anything European-sourced. For builders — good luck, it's everything.

Once you know your problem materials, build an early-warning system. Every time you win a job that needs one of those items, order it the same day you send the quote acceptance. Don't wait for the start date. Don't wait for the site induction. Order it now. If the job falls through, most suppliers will let you return unused materials or transfer them to the next job. The cost of holding a switchboard for two months is almost nothing compared to the cost of having your crew sitting on site with nothing to do.

This one separates the tradies who keep jobs running from the ones who spend half their week on the phone apologising to customers.

Right now — not next time you're in a panic — sit down and write out acceptable substitutions for every high-lead-time material you use. What brand X switchboard can you swap for brand Y without redesigning the whole board? What pipe fitting from supplier B does the same job as the one from supplier A? What cable can you upsize without breaking the spec?

Then have that conversation with your engineer or certifier before you need it. A quick call: "Look, if I can't get brand X isolators, is brand Y acceptable?" Nine times out of ten they'll say yes on the spot. But if you ask on Friday afternoon when you're meant to be testing on Monday, you're going to wait until Tuesday while they "check." And your customer is going to wonder why nobody's on site.

The goal is to have three options for every critical material before you start the job, not when you're halfway through and stuck.

There's a fine line between "I've got a buffer" and "I'm running a hardware shop out of my shed." But here's the reality: ordering exactly what you need for a job is a luxury we don't have anymore. If you order 50 metres of cable and you need 48, you've got no slack if a length gets damaged, a measurement was off, or the apprentice decided to use the offcut for a lead-light.

Smart tradies these days are ordering 10–15% over on anything with a lead time over two weeks. Yes, it ties up cash. Yes, you need somewhere to store it. But the alternative — having a crew of three standing around for half a day while you scramble to find an extra 12 metres of something — costs you way more in wages than the extra material cost. And the leftovers go on the shelf for the next job. Small jobs, service calls, warranty fixes — suddenly you've got stock for those without placing a panic order.

Just keep a proper offcuts and stock spreadsheet. "I'll remember what I've got" works until you don't, and then you're buying stuff you already have.

This is where most tradies drop the ball. Not because they don't know there's a delay, but because they don't want to deliver bad news. So they wait. They check with the supplier again. They hope it'll come in. And then suddenly it's the day before the material was meant to arrive and the customer's asking "so when do you start?"

Don't do that. As soon as you know there's a risk — not when it's confirmed, when it's a risk — tell the customer. "Look, this switchboard is showing 8–10 weeks at the moment. I'm ordering it today, but I want you to know now so we can plan the schedule around it." Customers respect honesty way more than they respect silence. And giving them early warning lets them adjust their own plans instead of being blindsided later.

Better still: build lead-time allowances into your quoting. If you know cable trays are on 6-week lead, don't quote a start date three weeks from now. Quote the start date at week seven, and if it comes in early everybody's happy. If it doesn't, you've got a buffer built in.

If you've only got one supplier for critical materials, you're one truck breakdown away from a stalled job. And I know — the tradie instinct is loyalty. You've got a rep you've known for years, they look after you on pricing, they slip you a discount at Christmas. I'm not saying ditch them. I'm saying build a backup.

Even if you only use supplier B once every three months, having an account that's set up, credit approved, and knows what you need means you've got a lever to pull when supplier A says "next month." It also means supplier A knows you've got options — and that tends to keep their service honest.

Here's where a good job management system earns its keep. If you're managing material orders on sticky notes and WhatsApp messages, you're going to miss something. Trade Track lets you attach materials and purchase orders to jobs, track what's been ordered, what's arrived, and what's still pending — all in one place. When a supplier calls and says "that order you placed three weeks ago is ready" you can check it against the job in two taps instead of digging through your email inbox.

When you've got 15 jobs running and three of them are waiting on materials, you need a system that doesn't rely on your memory. Because your memory is already full of everything else a trade business throws at you.

Supply chain delays aren't going anywhere. The tradies who adapt — who plan ahead, build substitution options, communicate early, and use the right tools — are the ones who keep jobs moving while everyone else is waiting on a phone call that never comes.

Trade Track helps Australian tradies manage jobs, materials, and schedules from one place — so when the supply chain throws a curveball, you're ready. No credit card required · 7-day free trial
