Step 1
Validate your idea before you spend anything
Most businesses fail because they build before they know if anyone will pay.
Step 2
Choose your business structure
Sole trader or company — this decision affects your tax, liability, and admin burden.
Step 3
Register your ABN
Every business needs an ABN before it can invoice clients legally.
Step 4
Open a dedicated business bank account
Mixing personal and business money creates tax headaches and legal problems.
Step 5
Register for GST if you need to
Mandatory over $75k revenue — optional below that threshold.
Step 6
Get business insurance
One incident without insurance can end a business. Don't skip this.
Step 7
Sort your contracts and terms
Verbal agreements are unenforceable. A simple contract protects both parties.
Step 8
Set up bookkeeping from day one
Good records make tax time simple and keep you on top of your cashflow.
