The decision tree
Software tier by business shape
Your shape
Tier
The candidates
Sole trader, no GST, no staff
Minimal: a bank feed plus set-aside discipline. A structured spreadsheet or a free tool genuinely suffices
Free or low-cost options, plus the ATO app for receipts
Sole trader or micro business, GST-registered
Entry paid tier. BAS-capable software pays for itself in coding accuracy alone
Xero entry plans, QuickBooks lower tiers, or an all-in-one model for the expense-light
Employer of any size
Payroll-capable tier, non-negotiable. Single Touch Payroll per pay run and super streaming rule out the minimal options entirely
Xero with payroll, MYOB Business, QuickBooks with payroll
Inventory, job costing or multiple entities
Full tier
MYOB's traditional strength, or Xero plus ecosystem apps, depending on shape
Software tier by business shape
Total cost of ownership: the honest comparison
Software pricing is the visible 20%, somewhere between nothing and about $100 a month. The invisible 80% is the accountant interface. Australian accountants overwhelmingly work natively in Xero and MYOB, so a file in the ecosystem your accountant knows is processed in hours, while a file in an exotic or free tool is exported, converted and re-checked at hourly rates that erase five years of subscription savings.
And a file that is behind is not a software problem at all. Months of unreconciled feed and unlodged BAS get fixed by reconstruction and lodgment, after which almost any mainstream tool maintains it.
Frequently asked questions
What is the best accounting software for a small business in Australia?
The right tier for your shape: minimal tools for sole traders with no GST, BAS-capable entry tiers once registered, and payroll-capable software the moment you employ.
Do I need accounting software at all?
Not below GST registration with no staff, where a disciplined spreadsheet works. GST makes software strongly advisable, and employees make payroll-capable software mandatory in practice.
Is the cheapest option worth it?
Compare total cost including your accountant's time. Mainstream-ecosystem files are dramatically cheaper to service than exports from exotic tools.
Xero, MYOB or QuickBooks?
Shape-dependent. Payroll needs, inventory and the apps you rely on decide it far more than headline features do.
Should I switch software to save money?
Rarely for price alone. Migration, retraining and broken history usually exceed the saving.
