Quick answer
Unsecured working capital is short-term funding for day-to-day running costs such as wages, stock, rent, supplier bills and tax, approved on turnover and bank statements with no property required. It can be a short-term loan, a line of credit or invoice finance. The right structure depends on whether your cash gap is a one-off, seasonal or ongoing.
Key points
- Working capital is the cash available for day-to-day expenses, as business.gov.au defines it.
- Unsecured working capital is sized on cash flow, not property.
- Match the structure to the gap: one-off (loan), recurring (line of credit), receivables (invoice finance).
- Funding a timing gap is healthy; funding ongoing losses usually isn't.
- Purpose
- Day-to-day running costs
- Typical unsecured range
- $5,000 to $500,000
- Speed
- Same-day funding possible for smaller amounts
What is working capital, and why does it run short?
In business.gov.au’s glossary, working capital is simply the money on hand for running costs. It runs short for reasons that usually have nothing to do with whether the business is profitable:
- customers pay on 30 or 60 day terms while wages go out weekly;
- a big order needs stock bought before it’s sold;
- BAS, PAYG and super land in the same month as a quiet trading period;
- growth means more staff and stock before the extra revenue arrives.
A business can be growing, profitable and still short of cash. That’s exactly what working capital finance is for.
Why go unsecured for working capital?
Because working capital needs are usually short, frequent and modest compared with property values. Tying a house to a six-week stock gap is using a sledgehammer on a thumbtack. Unsecured working capital is sized on turnover and bank statements, is quicker to arrange, and leaves property (if you have any) out of it.
The RBA’s October 2025 Bulletin recorded lenders saying they’re more open to unsecured and lightly secured lending, with non-banks gaining ground in small business lending, especially at the smaller end. That’s broadly where working capital sits.
Which structure fits your gap?
| Your gap looks like | Best-fit structure | Why |
|---|---|---|
| A one-off: a large order, a tax bill, a repair | Short-term unsecured loan | Fixed amount, fixed end date |
| Recurring: every month or quarter | Line of credit | Draw and repay as needed; pay only for what you use |
| Customers owe you on invoices | Invoice finance | The receivables fund the gap and grow with sales |
| Card-heavy with seasonal swings | Merchant cash advance | Repayments move with takings |
Getting the structure right often matters more than the amount. A business with a recurring gap that takes a lump-sum loan ends up paying for money it doesn’t need most of the year. A business with a one-off need that takes a line of credit may find the limit quietly becomes permanent debt.
How much working capital does a business need?
A practical way to estimate it:
- List your cash cycle. How many days from paying suppliers to getting paid by customers?
- Work out your weekly outgoings during that cycle: wages, rent, stock, super, other bills.
- Multiply the weekly outgoings by the number of weeks in the gap.
- Subtract the cash buffer you already hold.
The result is roughly how much working capital the gap needs. Then check it against what your turnover supports with the borrowing estimator.
business.gov.au’s cash-flow tips are worth reading alongside this: pricing for enough margin, invoicing earlier, reviewing costs and keeping stock levels in check all shrink the gap before you borrow.
When is working capital finance the wrong tool?
When the business is losing money month after month and the loan would simply fund the losses for longer. Lenders see this pattern in bank statements, and it usually leads to declines or, worse, approvals that make the hole deeper.
Signs to pause and look at the business first:
- revenue falling for three months or more with no clear cause;
- existing short-term facilities being refinanced to meet repayments;
- tax lodgements falling behind because there’s no cash to pay.
If that sounds familiar, a conversation with your accountant is the right first step. We’re also happy to say candidly whether funding would help or hurt; a short enquiry is enough to start.
What do lenders need to see for working capital?
- Six to twelve months of business bank statements.
- A clear explanation of the gap and how it closes (for example, “customer X pays on 45-day terms”).
- An aged receivables report if you invoice on terms.
- Your BAS lodgement status and any ATO payment plan.
- A list of existing facilities and their repayments.
Our page on what lenders look for in bank statements explains the patterns assessors focus on.
A worked example (illustrative)
A wholesale food distributor with a leased warehouse turns over roughly $210,000 a month. It has just won a supermarket supply contract that pays on 60-day terms. Supplying the first two months means buying about $120,000 of extra stock before any payment arrives.
A lump-sum loan could cover the first cycle, but the gap will recur for as long as the contract runs. A line of credit or invoice finance against the new contract would track the need more closely and cost less over time. The example is illustrative, but the principle holds: match the tool to the cycle.
How can you shrink the gap before funding it?
Every week you shave off your cash cycle is working capital you don’t need to borrow. Invoice as soon as work is done, ask for deposits on larger jobs, align supplier due dates with customer receipts, and keep stock lean on slow lines. Then fund what’s left. A smaller, well-matched facility is cheaper, easier to approve and easier to repay.

Working capital shouldn’t need a house behind it. Tell us about the gap and how it closes. Your credit file isn’t checked when you first enquire, your enquiry isn’t passed around a room full of lenders, and a real person helps you choose between a loan, a line of credit and invoice finance.

Frequently asked questions
Is working capital finance only for struggling businesses?
No. Growing businesses often need it most, because growth ties up cash in stock, wages and receivables before revenue arrives.
How long should a working capital loan run?
Ideally no longer than the gap it covers. Short-term needs suit short terms. Stretching a short gap over a long loan means paying for money you no longer need.
Can I use working capital finance to pay the ATO?
Yes, it's a common use, though it's worth comparing with an ATO payment plan first. Our page on BAS and tax bills weighs up both.
What's the smallest amount I can borrow?
Unsecured options typically start around $5,000. Very small needs may be better handled through a business card or supplier terms.
