5 Costly Financial Mistakes Small Business Owners Make (And How to Avoid Them)

Running a small business is a bit like juggling with one hand tied behind your back. You’re managing staff, keeping customers happy, handling inventory, marketing your products, and somewhere in that chaos, you’re supposed to be on top of your finances too.

Watch our latest video on this topic here.

At PBS Accountants & Advisers, we’ve seen it all over our 40+ years supporting Australian small businesses. Today, I’m sharing the most common (and costly) financial mistakes we see business owners make – and more importantly, how you can avoid them.

  1. Letting Your Books Slide Until Tax Time

Picture this: It’s June 29th, and you’re frantically sorting through a shoebox of receipts, trying to piece together your financial year before the tax deadline. Sound familiar?

Last month, I met with Sarah, a bakery owner in Black Forest who’d been putting off her bookkeeping for months. “I just don’t have time,” she explained, flour still dusting her apron. “Between 4am starts and managing staff, bookkeeping always falls to the bottom of my list.”

The problem? When you let your books slide:

  • You make decisions based on gut feel rather than actual numbers
  • You miss early warning signs of cash flow problems
  • You can’t spot opportunities for tax savings throughout the year
  • You pay your accountant more to clean up the mess (ironically costing you more than regular maintenance)

Solution: Set aside just 30 minutes weekly to update your books. Use cloud accounting software that connects to your bank and automatically categorises most transactions. Or better yet, let us handle your bookkeeping so you can focus on making those amazing sourdough loaves!

  1. Avoiding Your Accountant Until Tax Time (Because “It Costs Money”)

Many business owners only contact their accountant when they absolutely have to – usually at tax time or when there’s a crisis. Why? Because they assume every conversation comes with a bill attached.

Here’s the truth: Yes, accountants charge for their time. But that 30-minute call could save you thousands in tax or help you avoid a costly mistake.

I recently spoke with Michael, who runs a construction business. He was about to purchase a new digger for $19,000 and write it off immediately under the small business write off rules. Sounds good, right? Except Michael was already in a tax loss position this year – meaning he’d get zero immediate benefit from that deduction. A quick 15-minute call saved him from making a significant cash flow error.

Solution: Think of your accountant as part of your business’s success team, not just a necessary evil at tax time. At PBS, we encourage regular check-ins with clients. Many questions can be answered quickly, and the value far outweighs the cost.

  1. Making Big Decisions First, Asking Questions Later

“I’ve already signed the contract” are words that make accountants wince. Why? Because often, there was a better, more tax-effective way to structure things.

Common examples we see:

  • Purchasing assets in the wrong entity
  • Setting up incorrect business structures
  • Taking on commercial leases with unfavourable terms
  • Hiring employees when contractors might be more appropriate (or vice versa)
  • Selling business assets without considering tax implications

A client recently came to us after purchasing a commercial property in their own name. Had they consulted us first, we may have suggested using their self-managed super fund, or a trust structure potentially saving them tens of thousands in tax (and land tax?) over the property’s lifetime.

Solution: Before making any significant business decision, shoot your accountant a quick email or call. Think of us as your financial sounding board – we’ve seen hundreds of similar situations and can spot pitfalls you might miss.

  1. Neglecting Superannuation Until Retirement Looms

Superannuation is one of Australia’s best tax-saving vehicles, yet many business owners neglect it for decades. The thinking goes: “I’ll put money into my business now and worry about super later.”

The problem? You’re missing out on decades of compound growth and tax benefits.

Take Tom, a client who runs a successful retail shop. For 20 years, he put the bare minimum into super, focusing instead on his business. Now at 55, he’s playing catch-up, making massive contributions to try to build a retirement nest egg. While better late than never, he’s missed out on 20+ years of potential growth PLUS you are limited in what you can put in both by cashflow and the super contribution rules.

Solution: Make super part of your regular financial planning, not an afterthought. Consider making regular contributions throughout the year (which helps cash flow compared to one large payment) and explore strategies like salary sacrifice if you’re paying yourself a wage.

  1. Not Reviewing Your Super Fund’s Performance and Fees

Many business owners set up their super fund decades ago and never look at it again. Meanwhile, their hard-earned contributions are being eroded by excessive fees or underperformance.

A client recently brought in their super statement during a review meeting. They’d been with the same retail fund for 15 years, paying over 2% in annual fees. We connected them with a TRUSTED financial advisor who helped them switch to a more competitive option, potentially saving them over $100,000 in fees by retirement age.

Solution: Review your super fund at least annually. Compare performance against benchmarks and understand exactly what fees you’re paying. Consider whether a self-managed super fund might be appropriate for your circumstances, especially if you’re interested in direct property investment through super. Consult a trusted Financial Adviser.

The Real Cost of Financial Mistakes

The most painful part of these mistakes isn’t just the immediate impact – it’s the compounding effect over time. That extra tax you paid unnecessarily each year could have been invested and growing. Those super contributions you delayed could have been building your retirement nest egg.

At PBS Accountants & Advisers, we focus on building partnerships with our clients – relationships where you feel comfortable picking up the phone before making big decisions, not after. Where your books stay updated, so you always know where you stand. Where your super works as hard as you do.

Your Action Plan

  1. Schedule a financial health check – When was the last time you had a comprehensive review of your business finances?
  2. Set up a regular bookkeeping system – Whether in-house or outsourced, stay on top of your numbers.
  3. Diarise quarterly check-ins with your accountant – Prevention is better than cure!
  4. Review your super strategy – Are you on track for the retirement you want?
  5. Before your next big business decision, call us first – We might just save you a bundle.

Remember, successful business owners aren’t necessarily financial experts – they’re just smart enough to call one before making big decisions.
