Invoice Payment Terms in Australia: What You Need to Know
Setting clear payment terms on your invoices is one of the most important things you can do to protect your Australian business's cash flow. Unclear or missing payment terms are a leading cause of late payments, disputes, and bad debt for small businesses across the country.
Whether you're a freelancer, sole trader, or small business owner, this guide covers everything you need to know about invoice payment terms in Australia — from standard industry practices to your legal rights when clients don't pay.
Standard Payment Terms in Australia
The most common payment terms used by Australian businesses are:
Net 7
Payment due within 7 days of the invoice date. Common for small jobs, freelancers, and clients with good payment history.
Net 14
Payment due within 14 days. A good balance between giving clients time to process invoices while maintaining healthy cash flow.
Net 30
Payment due within 30 days. The most common term in B2B transactions. Many larger businesses default to this.
EOM (End of Month)
Payment due at the end of the month following the invoice date. Common in wholesale and construction industries.
COD (Cash on Delivery)
Payment due immediately upon delivery of goods or services. Common for new clients or high-risk transactions.
For small businesses dealing with cash flow pressures, shorter terms like Net 7 or Net 14 are recommended. The ATO also recommends clearly stating payment terms upfront to reduce disputes.
What to Include in Your Payment Terms
Every invoice you send should clearly state your payment terms. Here's what to include:
- Due date
State the exact due date, not just "Net 30". E.g., "Payment due by 14 March 2026."
- Accepted payment methods
Bank transfer (BSB and account number), PayID, credit card, or other methods you accept.
- Late payment fees
If you charge interest or fees on overdue invoices, state this clearly. E.g., "A 2% monthly fee applies to overdue amounts."
- Early payment discount (optional)
E.g., "2% discount if paid within 7 days." This can incentivise prompt payment.
- Dispute resolution process
Outline how disputes should be raised and the timeframe for resolving them.
Handling Overdue Invoices
Even with clear payment terms, some invoices will go overdue. Here's a recommended escalation process:
Step 1: Friendly reminder (1-3 days overdue)
Send a polite email reminding the client that payment is overdue. Often this is all that's needed — payments get lost or forgotten.
Step 2: Follow-up call (7-14 days overdue)
Call the client directly. Confirm they received the invoice and ask when payment will be made. Get a commitment in writing.
Step 3: Formal demand letter (30+ days overdue)
Send a formal letter of demand stating the overdue amount, accrued interest, and a final payment deadline before legal action.
Step 4: Debt collection or legal action (60+ days overdue)
Engage a debt collector or file a claim through the relevant state tribunal (e.g., NCAT in NSW, VCAT in Victoria) for amounts up to $100,000.
Your Legal Rights for Unpaid Invoices
Australian law provides several protections for businesses owed money:
- Late payment interest: You can charge interest on overdue invoices if your contract or terms specify this. The rate must be reasonable and clearly communicated upfront.
- Small Claims Tribunals: Each state has a tribunal for small business disputes. These are faster and cheaper than going to court.
- Security of Payments Act: If you work in the construction industry, the Building and Construction Industry Security of Payment Act gives you additional rights to claim unpaid amounts quickly.
- Statutory demand: For amounts over $4,000 owed by a company, you can issue a statutory demand. If unpaid within 21 days, you can apply to wind up the company.
- ASIC and AFCA: For disputes involving financial services, you may be able to lodge a complaint with the Australian Financial Complaints Authority (AFCA).
