💰 Cash vs Accrual Accounting: Why It Matters

One of the first decisions you’ll make in your business is how you record income and expenses.

Cash accounting records money when it actually moves in or out of your bank account.

Accrual accounting records income and expenses when they are earned or incurred, regardless of when cash is received or paid.

🧾 Understanding BAS

If you’re registered for GST, you’ll need to lodge a Business Activity Statement (BAS) with the Australian Taxation Office (ATO).
 
Your BAS reports things like:
 
  • GST collected on sales
  • GST paid on expenses
  • PAYG withholding (if you have employees)
