Running a small business in Alkimos, Western Australia, can be exciting, but let’s be honest—it’s not easy. Between serving customers, managing staff, and keeping up with day-to-day operations, bookkeeping often slips to the bottom of the to-do list. That’s where many Aussie business owners go wrong. Bookkeeping mistakes don’t just cause confusion; they can trigger cash flow issues, ATO penalties, and unnecessary stress.
At JGW Bookkeeping, we’ve seen firsthand how small businesses in Australia struggle with their accounts, and we know how costly small errors can become if ignored. Let’s look at the top 5 bookkeeping mistakes Aussie businesses make—and how you can avoid them with the right support.
1. Mixing Personal and Business Finances
One of the most common bookkeeping mistakes small business owners make is blending personal and business expenses. Swiping the same card for groceries and business purchases might feel convenient, but it creates a nightmare when tax time arrives. Not only does it waste hours of sorting receipts, but it also risks incorrect deductions and ATO red flags.
Solution: Open a dedicated business account and keep all personal transactions separate. If you’ve already mixed them up, a local bookkeeper in Alkimos like JGW Bookkeeping can help you untangle the mess.
2. Not Reconciling Bank Accounts Regularly
Bank reconciliation is one of the most overlooked bookkeeping tasks. Many Aussie business owners assume their bank balance reflects their true financial position, but that’s rarely the case. Unmatched transactions, double entries, or missed payments can distort your numbers.
Why it matters: Without regular bank reconciliation, businesses in Western Australia risk inaccurate reporting, overspending, and even fraud slipping through unnoticed.
Solution: Monthly reconciliation is essential. Our BAS agent tips at JGW Bookkeeping ensure your accounts are matched, balanced, and error-free.
3. Late BAS Lodgement
Every small business in Australia knows the stress of lodging a BAS on time. Yet many leave it until the last minute or miss deadlines completely. The result? ATO penalties, late fees, and extra stress.
Solution: Schedule BAS lodgements ahead of time and work with a registered BAS agent like JGW Bookkeeping in Alkimos. We lodge your BAS on time, every time—no headaches, no penalties.
4. Poor Record Keeping
Shoeboxes full of receipts or scattered Excel files are still shockingly common among small businesses. Poor record keeping makes it nearly impossible to track expenses, claim deductions, or prepare accurate reports.
Why it matters: Disorganised records lead to poor decision-making, missed tax deductions, and confusion when the ATO comes knocking.
Solution: Implement a reliable record-keeping system. At JGW Bookkeeping, we offer bookkeeping help Australia-wide with organised processes that keep your finances neat and compliant.
5. DIY Bookkeeping With No Compliance Check
With so many online tools available, some small business owners in Western Australia attempt to “do it all themselves.” While DIY bookkeeping might seem cost-effective, it often results in errors, missed BAS obligations, and non-compliance. What starts as saving money can quickly spiral into paying fines.
Solution: Partnering with a local BAS agent like JGW Bookkeeping ensures compliance with Australian tax laws while freeing up your time to focus on growing your business.
