You finish a big month. Plenty of jobs completed. Customers paid their invoices.
You open your banking app and see a healthy balance.
Things must be going well… right?
Not always.
One of the biggest financial traps for tradies is assuming that money in the bank equals profit. In reality, your bank balance and your job profit are two completely different numbers — and confusing the two can quietly hurt your business over time.
Let’s break it down in plain English.
The Number That Really Matters: Job Profit
Job profit is the actual money you make on a job once all the costs of doing that job are taken into account.
That includes things like:
- Materials
- Labour (including your own time)
- Subcontractors
- Equipment hire
- Fuel and site costs
The basic calculation looks like this:
Job profit = Job income – Job costs
Sounds simple, but many tradies don’t track this properly.
If you’re quoting jobs without understanding the true cost of doing the work, you can end up busy all month but making very little money.
What Your Bank Balance Is Actually Telling You
Your bank balance only shows cash movement. It doesn’t tell you whether a job was profitable.
There are plenty of things that can inflate your bank balance that aren’t profit, including:
- Deposits for future jobs
- GST collected on invoices
- Loan funds or overdrafts
- Money that needs to pay suppliers
- Tax that hasn’t been paid yet
For example, you might receive a $15,000 deposit for a renovation job. Your account suddenly looks fantastic.
But that money still needs to pay for:
- Materials
- Wages
- Subcontractors
- GST
- Income tax
Until the job is finished and all the bills are paid, that money isn’t yours yet.
Why So Many Tradies Feel “Busy But Broke”
This confusion between bank balance and real profit is incredibly common in trade businesses.
Here are a few reasons why.
Deposits Feel Like Income
Money sitting in your account for unfinished jobs can easily be mistaken for profit.
GST Looks Like Extra Cash
That 10% on your invoices is actually the ATO’s money, not yours.
Tools and Vehicles Mask Profit
Buying equipment might not hurt your bank balance immediately, but it reduces your real profitability.
Your Own Time Isn’t Costed
Many tradies forget to include their own labour in job costs. A job might look profitable on paper, but when you factor in your time, it often isn’t.
A Quick Example
Let’s say you complete a job for $5,500 (including GST).
Your costs look like this:
- Materials: $2,000
- Labour: $1,500
- Other costs: $500
Total job costs = $4,000
That leaves $1,500 in job profit before tax.
But your bank account shows the full $5,500 coming in, which can make things look far more profitable than they really are.
Without tracking the job numbers properly, it’s easy to assume the business is doing better than it actually is.
Tradies Who Track Job Profit Make Better Decisions
When you start focusing on job profitability instead of just your bank balance, everything changes.
You can:
- Price jobs properly
- Identify your most profitable work
- Stop doing jobs that lose money
- Improve cash flow planning
- Grow your business with confidence
Instead of guessing, you’re running your business with real numbers.
Simple Habits That Make a Huge Difference
If you want to stay on top of your numbers, start with a few basic habits:
✔ Track income and costs for every job
✔ Move GST into a separate account
✔ Review monthly profit reports
✔ Put money aside early for tax
✔ Work with a bookkeeper or accountant who understands tradies
Small changes like this can completely transform how your business performs.
The Bottom Line
A big bank balance can disappear quickly if the jobs behind it aren’t profitable.
But a business that understands its job profitability builds something much stronger — consistent income, better pricing, and long-term wealth.
Because at the end of the day:
Being busy doesn’t make you successful.
Being profitable does.
