319. What banking setup does your small business actually need?

Opening a separate business account sounds simple until the money starts coming in. Suddenly you’re juggling tax, GST, payroll, profit, late invoices, interest and the uncomfortable reality that a healthy-looking balance may not actually be yours to spend.

So what does a banking setup need to do once a side hustle starts becoming a real business?

In this episode, Tash and Emma compare the banking setups they’ve built through the sole trader and company stages, including what went wrong when business and personal money were mixed. They also unpack tax buckets, cash buffers, paying yourself, business savings accounts and why revenue can look much better than the money you actually keep.

In this episode we'll discuss:

💸 How side hustle income can start feeling like “spare money this week” when it lands in your personal account, and what happens when tax barely enters the equation.

🏦 How their banking systems evolved from one account to separate buckets for tax, GST and profit, and why a simpler setup can sometimes work once cash flow becomes more predictable.

🧾 Why not all the money sitting in a business account is actually available to spend, even when the business itself is making a loss.

💰 The trade-off between keeping business cash accessible and earning interest, including around $200,000 sitting inside Tash Invest and the Macquarie and NAB split used to make that cash work harder.

📉 Why cash buffers matter when invoices arrive late or conditions change, and what businesses failing after only a short downturn can reveal about planning for the good times and the bad.

📊 Why selling something for $100 and spending $30 to make it does not mean you’ve made $70 once tax, time, licences, insurance, software and other costs enter the picture.

👩‍💼 Why $100,000 in business revenue is very different from a $100,000 salary once super, sick leave, annual leave and business expenses are stripped out.

💳 How paying yourself gets trickier when income fluctuates, and why percentages or a base salary plus occasional top-ups can make the maths easier to manage.
