7 Risky Customers for Tradies: Red Flags to Avoid looks at something most tradies eventually learn the hard way – not every job is worth winning.
You can quote the job properly, turn up when you said you would, and do quality work. Yet one difficult customer can still turn a good job into weeks of chasing money, arguing over variations and wondering why you took it on.
The trick is spotting the warning signs before the tools come out.
Our Spotting Risky Customers guide covers some of the early signs that a customer could become a problem, including avoiding written agreements, fighting over price, dodging deposits, and constantly changing the scope.
Here are seven red flags worth watching. 🚩
1. They Won’t Put Anything in Writing
“Don’t worry, mate. We’ll sort it out.”
Those words can sound harmless when you’re standing on site.
Three weeks later, you may have a very different memory of the conversation from the customer.
Quotes, approvals, changes, and variations don’t need to turn into mountains of paperwork. However, you do want a clear record of what everyone agreed to.
If a customer actively avoids putting anything in writing, ask yourself why.
A quick email or written approval can save a much bigger argument later.
2. They’re Haggling Before You’ve Even Quoted
There’s nothing wrong with a customer having a budget.
There is a difference, though, between discussing the budget and trying to grind your price down before you’ve even worked out what the job involves.
If someone has already decided you’re “too expensive” before seeing the quote, that attitude may not disappear once work starts.
It can become:
“Can you throw this in?”
“Surely that won’t cost extra?”
“My mate said he’d do it cheaper.”
That last one even gets its own mention in our eGuide for good reason.
You don’t need every job.
Sometimes protecting your margin is worth more than filling another space in the calendar.
3. Every Other Tradie Was Apparently Useless
One bad experience with another tradie? Fair enough.
Five bad experiences?
Pay attention.
If every builder, sparky, plumber, landscaper, or other tradie they’ve hired has apparently been hopeless, you may want to find out why.
You could be hearing a genuine story.
Or you could be hearing a preview of what they’ll say about you.
🚩 Don’t ignore the pattern just because you want the job.
4. They Dodge the Deposit
You’ve quoted the job. They’ve accepted it. They’re desperate for you to start.
Then you ask for the agreed deposit.
Suddenly, things get complicated.
They’ll pay it next week. They’re waiting for money to clear. They want you to order the materials first. They need you to get started because the job is “urgent”.
This is where a busy schedule can tempt you into taking the risk yourself.
Think carefully before doing it.
As the eGuide points out, taking a deposit before ordering materials helps stop you from funding someone else’s job from your own pocket.
Your suppliers still expect payment.
The boys still need their wages.
Fuel still needs to go in the ute.
A full calendar doesn’t help much when you’re constantly paying job costs before customers pay you. 💸
5. Everything Is Urgent Until You Need an Answer
They need the job started yesterday.
But you need them to choose a product?
Silence.
You need access confirmed?
Nothing.
You need them to approve the quote?
“I’ll get back to you.”
Then, two days later:
“When can you start?”
A customer who creates urgency but won’t make decisions can quickly throw out your schedule.
That affects more than one job. It can leave the boys waiting around, materials sitting unused, and the next customer wondering why you’re late.
Good jobs need decisions from both sides.
6. The Scope Keeps Changing but the Price Can’t
This is where a profitable job can quietly go backwards.
The customer asks for “one little extra”.
Then another.
Then something else while you’re already there.
None of them seem huge on their own.
Put them together, and you’ve supplied extra materials and several additional hours without charging for them.
The eGuide recommends putting every variation in writing and getting it signed off before completing the extra work.
That doesn’t make you difficult.
It makes the job clear.
When something changes, record what’s changing and what it will cost.
7. You’re Not Clear About Who Is Actually Paying
This one can get messy quickly.
You might be dealing with a tenant, property manager, builder, homeowner, or another contractor.
Everyone seems to know what’s happening.
Except nobody has clearly confirmed who will pay your invoice.
Before starting, make sure you know who your customer actually is.
Who approved the work?
Who receives the invoice?
Who is responsible for payment?
When is payment due?
Those questions are much easier to sort out before you’ve done $8,000 worth of work.
Protect the Job Before You Start It
Spotting a red flag doesn’t automatically mean you should knock the job back.
It means you may need better boundaries before saying yes.
For larger jobs, that could include a written scope, deposit, progress payments, approved variations, and clear payment terms.
The eGuide recommends progress payments for work running longer than a week or two, along with clear payment terms on quotes and invoices.
Those processes can also make the bookkeeping side much cleaner.
When your quote, deposit, variations, progress claims, and final invoice line up, it’s easier to see what you’ve billed, what has been paid, and what you’re still owed.
That’s particularly important when you’re trying to keep your bookkeeping up-to-date rather than discovering problems months later.
The Customer Who Doesn’t Pay Can Be Your Most Expensive Job
A $20,000 job isn’t really a $20,000 job if you spend months chasing the last $8,000.
And a job isn’t profitable simply because there was money left after buying the materials.
Your time matters too.
So does the time spent sending reminders, answering disputes, checking the bank account, and digging through old messages trying to prove what somebody agreed to.
That’s why the advice on the final page of our Spotting Risky Customers guide is simple: trust your gut, put the scope in writing, and take a deposit. Clear terms can prevent many problems before they start.
You can also find useful guidance on contracts and getting paid through the Australian Small Business and Family Enterprise Ombudsman.
Sometimes the Best Job Is the One You Don’t Take
Being booked solid doesn’t mean saying yes to everybody.
A customer who questions every dollar, refuses a deposit, changes the scope, and won’t put anything in writing may be telling you exactly what working with them will be like.
Listen early.
A gap in next week’s calendar might cost you less than three months spent chasing an invoice. 👀
