Let’s face it – being a small business owner is no joke.
You’re juggling clients, projects, quoting jobs, doing the work, chasing payments, paying staff or suppliers, and – somewhere in there – trying to make sure you actually get paid.
But if it feels like you’re always hustling and still living week to week, chances are… your money systems are working against you, not for you.
And here’s the thing: it’s not about how smart you are or how hard you work. Most business owners weren’t taught how to manage their money. You were probably just thrown into the deep end, figuring it out as you go.
The good news? You can stop spinning your wheels, and it starts by avoiding the most common financial traps.
In this blog, I’ll walk you through the 5 biggest money mistakes I see every week and more importantly, show you how to fix them fast so you can take back control and finally feel financially secure in your business.
Mistake #1: Not Paying Yourself a Regular Wage
Let’s talk about one of the most common (and painful) mistakes small business owners make: they don’t pay themselves consistently.
You might be saying:
“I take money out when I need it.”
“There’s never enough to pay myself regularly.”
“I’ll pay myself properly when things settle down.”
Here’s the problem with that: you’re running your business like an ATM, not a real operation. And that mindset will keep you broke – even when you’re making good money.
🔧 The Fix:
Set up a dedicated Owner’s Pay account, and start paying yourself a consistent wage every week or fortnight. Even if it’s only $200 to start, build the habit. When you get paid from clients, transfer a fixed percentage into your Owner’s Pay account – just like you’d pay an employee.
This does two things:
- It forces you to treat your income seriously.
- It allows you to plan and budget your personal life better.
The Edge coaching program teaches you how to calculate your break-even wage and build a cash flow system that actually works for your business.
Mistake #2: Mixing Personal and Business Finances
It might seem harmless to buy a Bunnings tool on your personal card or pay the rego for the work ute from your grocery account – but over time, this creates a total mess.
It’s impossible to track how your business is performing if everything is muddled together. You won’t know what you’re spending, earning, or saving – and when tax time rolls around, you’ll be in a world of pain.
🔧 The Fix:
Set up two separate bank accounts at the bare minimum:
- One for business income and expenses
- One for personal living
Better yet, I recommend creating five simple business accounts:
- Income – all revenue lands here
- Owner’s Pay – your regular wage
- Expenses – for bills, tools, and running costs
- Tax & BAS – set aside 25 – 30% per payment
- Profit – for business growth or rainy days
Once this is in place, your financial clarity skyrockets. You’ll know exactly where your money is going, and you’ll be less tempted to “accidentally” spend it.
Mistake #3: Ignoring the Numbers
This one’s a biggie, and I get it. Many small business owners avoid looking at their numbers because they’re overwhelmed, too busy, or just afraid of what they’ll find.
But let’s be honest – if you don’t know your numbers, you don’t know your business.
You can’t improve what you don’t measure.
🔧 The Fix:
Start by checking these numbers weekly:
- Revenue: What came in?
- Expenses: What went out?
- Net Profit: What’s left over after expenses?
- Break-even: How much do you need to earn to cover costs and pay yourself?
Create a simple weekly “money date” even just 30 minutes every Friday, to review your finances, send invoices, follow up on payments, and track your progress.
In The Edge, we give you simple templates to track this in under 10 minutes a week (no accountant brain required).

Mistake #4: No System for Tax and BAS
You know the drill: things are going well… until BAS time hits. Suddenly the ATO wants thousands you didn’t put aside, and you’re scrambling to pay.
Sound familiar?
Many small biz owners treat BAS like a nasty surprise – but it’s completely avoidable if you plan for it. Any case remember it’s not your money in the first place.
🔧 The Fix:
Every time you get paid, immediately transfer 25 – 30% into your Tax Account for taxes and BAS. Pretend it’s not yours. Because technically – it’s not. That’s the ATO’s cut.
If you’re registered for GST, track your income and expenses monthly and lodge on time. Using software like Xero, QuickBooks, or even a simple spreadsheet will make this 10x easier.
Imagine having a tax bill and already having the money sitting there ready. That’s the kind of peace The Edge helps you create.
Mistake #5: Undercharging for Your Work
This one hurts because you’re working hard, showing up, and doing great work… but the money just isn’t adding up.
Often, it’s because you’re undercharging. Maybe you’re pricing based on what others charge, or you’re too scared to raise your rates in case you lose clients.
But here’s the thing: if your pricing doesn’t cover your expenses, time off tools, admin time, and leave a profit – you’re not running a business. You’re running a charity.
🔧 The Fix:
- Add up everything it costs to run your business monthly (including paying yourself)
- Work out how many hours you realistically work and how many jobs you can do
- Divide your monthly costs by the number of billable hours or jobs – that’s your true minimum rate
- Add a profit margin
Also, factor in time spent quoting, driving, admin, and materials. You’re not just being paid for the hour on site, you’re being paid for all the time and expertise it takes to do the job well.
In The Edge, we give you a simple pricing tool to calculate your true rate with confidence – so you never wonder, “Am I charging enough?” again.
Bonus Tip: You Don’t Have to Figure This Out Alone
Here’s the thing most people won’t tell you: money stress isn’t about how much you make. It’s about how you manage what you’ve got.
And most small business owners were never taught how to do this. You’ve just been doing the best you can with what you know.
But what if there was a better way?
What if, in just 6 weeks, you could:
✅ Pay yourself regularly
✅ Get your tax sorted and stop panicking at BAS time
✅ Know your numbers and feel in control
✅ Charge with confidence
✅ Build a buffer so you’re never caught off guard
✅ Actually enjoy running your business again?
