Australia's payment reality, in three numbers
If you invoice with 30-day terms and assume your customers will pay on time, you're not just being optimistic — you're being misled by the contract. Three Australian data sources tell the same story:
| Source | Finding | What it means |
|---|---|---|
| Atradius Payment Practices Barometer AU 2025 | Average DSO is 52–55 days for AU B2B | Almost twice the typical 30-day invoice term |
| ASBFEO Payment Times Report | 69% of AU small businesses are not paid within 30 days | Late payment is the norm, not the exception |
| Master Builders Australia (FY24) | 11.6% of construction invoices are over 60 days overdue | One in nine construction invoices is severely late |
DSO (Days Sales Outstanding) is the standard accountancy metric for how long it takes a business to collect cash after a sale. A 30-day invoice term should produce a DSO close to 30 — anything materially higher means buyers are stretching out payment.
Why large companies pay slowest
The Atradius 2025 data exposes a pattern most small business owners already know intuitively: the bigger your customer, the longer they take to pay. Average DSO by buyer size:
- Small buyers (under 50 staff): ~50 days
- Mid-market buyers (50–250 staff): ~52 days
- Large enterprise buyers (250+ staff): ~58 days
Large buyers run formal accounts payable cycles — invoice received, approved, batched, paid in the next monthly run. Even on "30-day" terms, the ops reality is closer to 60 days. ASBFEO has been pushing the federal government's Payment Times Reporting Scheme partly to expose this.
Industry breakdown — the slowest payers in AU
Sector data from Atradius and Master Builders shows wide variation:
| Industry | Typical payment behaviour | Source |
|---|---|---|
| Construction & infrastructure | ~65-day average terms; 11.6% >60 days overdue | Master Builders FY24 |
| Government & large enterprise | ~58 days average DSO despite 30-day terms | Atradius AU 2025 |
| Manufacturing | ~55 days average DSO | Atradius AU 2025 |
| Wholesale & retail trade | ~50 days average DSO | Atradius AU 2025 |
| Professional services | ~45-50 days; high incidence of "scope dispute" excuses | Atradius AU 2025 |
| Healthcare (B2B suppliers) | ~50 days; institutional buyers run slow | Atradius AU 2025 |
If your business is on the supplier side of any of these — particularly construction subcontractors and SMB suppliers to government — you should expect to wait, plan cash flow accordingly, and act early when an invoice slips.
The compounding cost of waiting
Late payment isn't just a cash-flow inconvenience. CreditorWatch's Business Risk Index data shows what happens to debtors who miss payments:
- 1 default — 20% probability of business failure within 12 months
- 2 defaults — 42% probability of business failure within 12 months
- 3+ defaults — 62% probability of business failure within 12 months
In plain English: the longer you let an unpaid invoice sit, the more likely your debtor is going broke. Waiting doesn't make recovery easier — it makes recovery less likely. By the time a debtor is 90+ days late, you're competing with their other creditors for whatever's left.

What "good practice" actually looks like
Drawing from Atradius, ASBFEO, and the experience our solicitor partners see across NSW commercial work:
- Day 1–7 after due date: friendly reminder by email. Don't escalate yet.
- Day 8–14: firm follow-up referencing the invoice and stating an escalation deadline.
- Day 14: send a formal letter of demand. Most B2B debts resolve at this stage.
- Day 21–30: if unpaid, escalate — small claims court, debt collector, or solicitor depending on amount.
- Day 60+: probability of recovery drops sharply. Don't wait this long.
The 2026 Late Payer Index — named companies, named numbers
Our 2026 Australian Debt Collection Report goes beyond industry averages and names the 40 individual large Australian businesses with the worst 95th-percentile payment times to small business suppliers. All data is sourced directly from each company's own statutory disclosures on the Commonwealth Payment Times Reports Register — meaning it is public, admissible in court, and reported by the debtor itself.
The top 10 slowest large-business payers in Australia:
| Rank | Entity | 95th-pct (days) | % over 60 days |
|---|---|---|---|
| 1 | Hewlett-Packard Australia | 986 | 95.2% |
| 2 | MN Builders Group | 346 | 63.7% |
| 3 | Liberty Primary Metals | 260 | 86.0% |
| 4 | Gadens (law firm) | 252 | 29.5% |
| 5 | Danisco Australia | 219 | 34.0% |
| 6 | Barrick Resources (Aus) | 213 | 52.2% |
| 7 | Sinopec Oil and Gas Australia | 209 | 10.0% |
| 8 | Autosports Group | 202 | 24.4% |
| 9 | Travelcube Pacific | 200 | 10.0% |
| 10 | Infor (ANZ Holdings) | 192 | 10.1% |
Source: Commonwealth Payment Times Reports Register, 18 May 2026, analysed in the 2026 Australian Debt Collection Report. The 95th-percentile payment time means 5% of small business invoices took longer than this to be paid.
Three observations the report draws from this data. First, system-wide, only 2.3% of large reporting entities meet the "Fast Small Business Payer" benchmark (95% of invoices paid within 20 days, sustained over two consecutive periods). Five years into the regulatory regime, fast payment to small suppliers remains rare. Second, average payment time and 95th-percentile payment time are decoupled — 14 of the top 40 entities have an average under 50 days but a 95th percentile over 120 days. Looking at means alone hides the long tail. Third, the system-wide 95th-percentile payment time deteriorated from 58 days in the prior reporting cycle to 64 days in January–June 2025. Things are getting worse, not better.
