Quick answer
An unsecured business line of credit is an approved limit you can draw from when needed, repay and draw again, without offering property as security. The limit is sized on turnover and bank statements. You generally pay for what you draw rather than the full limit, which makes it well suited to recurring cash-flow gaps like supplier bills landing before customers pay.
Key points
- A reusable limit rather than a lump sum; draw, repay and redraw.
- Sized on turnover and account conduct; no property needed.
- Best for recurring timing gaps, not for one-off large purchases.
- Ask how undrawn limits are charged; some lenders charge line fees.
- Structure
- Revolving limit
- Security
- No property; guarantees common
- Best for
- Timing gaps and seasonal swings
How does an unsecured line of credit work?
Your turnover and bank statements set the size of an approved limit. You draw what you need, when you need it, up to that limit. As you repay, the available balance frees up again. business.gov.au’s glossary describes it as borrowing from an account up to a pre-approved ceiling.
No property is involved. Like most unsecured facilities, directors usually guarantee it, and the lender watches how the business account behaves over time.
When does a line of credit beat a lump-sum loan?
The rule of thumb is simple: if the gap comes back, use a line of credit. If it’s a one-off, use a loan.
| Situation | Better fit | Why |
|---|---|---|
| Supplier bills land weeks before customers pay | Line of credit | The gap recurs every month or quarter |
| Buying a specific machine | Term loan or equipment finance | One-off cost with a known amount |
| Seasonal stock build before a busy period | Line of credit | Draw before the peak, repay after it |
| Quarterly BAS lands in a tight month | Line of credit | Short, predictable need |
| Fit-out of a new room | Term loan | Single project with a lasting benefit |
Paying only for what you draw is the key advantage. A business that needs $40,000 for three weeks each quarter would pay for an entire lump sum all year if it borrowed a term loan. With a line of credit, it pays for the weeks the money is actually out.
How is the limit sized?
Much like an unsecured loan: turnover, consistency, time trading, existing debts, industry and credit history. Because a line of credit can be drawn repeatedly, some lenders are a little more conservative with the initial limit, then review it once they’ve seen how you use it.

What should you ask about costs?
We don’t publish rates because every facility is priced on the business’s circumstances. What we can tell you is what to ask:
- Is there an establishment fee?
- Is there a line fee or monthly fee on the undrawn limit?
- How is each drawdown repaid, and over what period?
- Are there fees for each draw?
- What triggers a review or reduction of the limit?
The answers make a big difference to what the facility really costs you, especially if you only draw occasionally.
If a line of credit sounds like the right shape, start your enquiry and we’ll look at what limit your figures support.
Who gets the most out of a line of credit?
- Tradies and contractors paid on 14, 30 or 45-day terms while materials and wages go out weekly.
- Wholesalers and distributors whose suppliers want payment before retailers pay them.
- Seasonal businesses that need to build stock or staff before a peak.
- Professional practices where fees are billed monthly but wages are paid fortnightly.
If your timing gap is specifically customers paying late on invoices, compare the line of credit with invoice finance, which advances against the invoices themselves. Our page on slow-paying customers weighs up both.
How do you use a line of credit well?
The facility works best when paired with a few firm habits. A few habits keep it working for you:
- Draw for timing, not for losses. If you’re drawing every month and never getting back to zero, the problem is margin or pricing, not timing.
- Repay promptly when customers pay. The quicker the balance returns to zero, the less it costs.
- Keep a buffer. Don’t run the limit to the maximum; leave room for the unexpected.
- Watch your statements. A lender reviewing your limit will read them too.
business.gov.au’s cash-flow advice includes collecting cash faster and sending invoices earlier. Those habits reduce how often you need to draw at all. Our guide comparing a card, a line of credit and a loan goes further on matching the tool to the job.
Is there a catch?
The main risks are behavioural. Because a line of credit is easy to draw, it can quietly turn into permanent debt. Some facilities also carry fees that make occasional use expensive. And a limit can be reviewed or reduced if trading deteriorates, which means it shouldn’t be the only buffer you have.
How do you choose the right limit?
Bigger isn’t automatically better. Some lenders count your full limit as potential debt, even when it’s undrawn, which can reduce what’s available elsewhere. A practical approach:
- Look back over the last twelve months and find the largest timing gap you had.
- Add a modest buffer for the unexpected.
- Ask for a limit around that figure, not the maximum you could get.
You can ask for a review later if your needs grow. A right-sized limit that’s used and repaid regularly usually serves a business better than a large one that sits idle.

If your cash flow has a rhythm, a line of credit can smooth it without any property on the table. No credit check is run when you first enquire. We don’t spread your details across a network of lenders, and a real person will call to understand how your money moves.

Frequently asked questions
Is a line of credit the same as an overdraft?
They're similar. business.gov.au explains an overdraft as spending past your account balance, and a line of credit as drawing up to a set, approved ceiling. In practice, unsecured lines of credit from non-bank lenders often sit separately from your transaction account.
Do I pay anything if I don't draw on it?
That depends on the facility. Some charge only on drawn balances; others have an establishment fee, a monthly line fee or both. Ask about all fees before you sign.
How is each drawdown repaid?
Some facilities repay each draw over a set number of weeks. Others require a minimum monthly repayment. The structure affects cash flow, so choose one that matches your income pattern.
Can the lender reduce my limit?
Most facilities allow periodic reviews. If turnover drops sharply or account conduct worsens, a limit can be reduced. Consistent use and repayment usually supports it staying in place or rising.
