A business line of credit is a limit that a lender approves in advance, which you can draw on whenever the business needs cash and pay down when money comes in. Unlike a term loan, which pays out one amount and runs to a schedule, a line of credit is more like a tank you fill and empty. This page explains how the limit is set, what it costs to keep, and the situations where a different product does the job better.
How does a business line of credit work?
A business line of credit works in a loop: the lender sets a limit, you draw what you need, you repay from takings, and the repaid amount becomes available again. Interest is usually charged on the balance you have drawn, not on the whole limit.
Most facilities have a review date, commonly once a year, when the lender decides whether to renew, raise or reduce the limit. Repayments are often interest on the drawn balance plus a required minimum, though the exact structure varies by lender.
In plain terms, it is a standing arrangement rather than a one-off loan. That makes it good at smoothing cash flow and poor at funding something you will use for ten years.
How is a line of credit limit decided?
A lender sets the limit from the cash the business actually moves, the history behind it, and whatever security is on offer. The more evidence of regular receipts and the stronger the security, the bigger and more stable the limit.
Typical inputs:
- Business bank statements for the last few months, showing deposits and spending patterns
- Turnover and trading history, including how long the ABN has been active
- Existing debts and repayments, so the new limit does not stretch the business
- Security, such as property, or a director’s guarantee where there is none
The Reserve Bank’s October 2025 bulletin on small business finance notes the share of SME credit that is unsecured has stayed below 5 per cent. In practice that means most limits are backed by something. An unsecured limit is available, but it is smaller and tends to be reviewed more tightly. Our page on unsecured business loans explains how those are assessed, and secured vs unsecured business loans sets out the trade-offs.
When does a line of credit beat a term loan?
A line of credit beats a term loan when the need repeats, the amount changes from month to month, or you cannot say in advance how much you will need. A term loan wins when the amount is fixed and the purpose is one-off.
| Situation | Line of credit | Term loan |
|---|---|---|
| Seasonal stock before a busy period | Draw as stock arrives, repay as it sells | Pays a lump you may not fully use |
| Wages gap while a big invoice is outstanding | Draw for weeks, repay on payment | Fixed repayments continue after the gap closes |
| Buying a vehicle or machine | Poor fit; limit may be reviewed mid-life | Better fit; term matches the asset |
| Urgent one-off amount, such as a tax bill | Slower to set up | Often quicker to arrange |
| Unknown peak cash need | Flexible | Risk of borrowing too much or too little |
If the gap is short and the amount is known, a short term business loan is often the simpler tool. If the real problem is a thin cash cycle, our working capital loans page covers how to size it.
What can you use a business line of credit for?
A line of credit is best used for money that comes back within weeks or months. Typical uses are:
- Buying stock ahead of a peak season, then repaying as it sells
- Covering wages and rent while customers take their time to pay
- Taking up a supplier discount for paying early
- Absorbing a quarterly tax payment while receipts catch up
It is a poor fit for assets with a long life, such as a delivery van or a fit-out. Those belong on a loan that runs for as long as the asset does, which is where equipment finance comes in.
Illustrative example: a seasonal retailer
Illustrative example: a gift retailer expects a rush in the last quarter of the year. It has a $150,000 limit and draws $60,000 in September to buy stock. In November it draws another $40,000 for extra casual wages. By late January, takings from the season have cut the drawn balance back to $20,000.
At no point did the business borrow the full $150,000, and the $130,000 it was not using in late January stood ready for the next gap. A $100,000 term loan taken in September would have meant repayments running all through the slow months, whether or not stock had sold.
The catch: the same limit can be reviewed and reduced. If the retailer had a weak season and the lender cut the limit to $80,000, the business would have to repay the excess or refinance. A line of credit is only as dependable as its last review.
Who is a business line of credit right for?
A line of credit suits businesses whose income arrives in lumps while costs arrive in a steady stream. If that describes your trading, a revolving limit can take the stress out of the gaps.
Common fits:
- Trades and contractors who pay for materials and labour well before a progress claim is paid
- Wholesalers and importers who buy stock in bulk and sell it down over several weeks
- Seasonal retailers and hospitality venues with a busy quarter and a quiet one
- Agencies and professional services whose clients pay on 30 or 60 day terms
It suits them because the need is real but the size of it moves. A fixed loan sized to the peak leaves them paying for money they are not using. A fixed loan sized to the average leaves them short at the peak.
It is a worse fit for businesses that are borrowing to cover a loss rather than a timing gap. Lenders can see the difference in the bank statements, and so should you: if the account is falling month after month, the answer is in the margins, not the facility.
What should you watch with a line of credit?
Watch three things: living on the limit, review dates and the true cost of keeping it open.
- Living on the limit. If the drawn balance never falls, the facility has become permanent debt. That is a sign to switch to a term structure.
- Review dates. Know when the lender will reassess and keep your bank statements in order beforehand.
- Ongoing fees. Set-up, annual and line fees can apply even when nothing is drawn. Flexibility costs more than a plain bank loan, so pay for it only if you will genuinely use it.
Keep a simple habit: each month, write down the highest balance you drew and the lowest. If the lowest never gets near zero, the business is using the limit as permanent funding and it is time to talk about restructuring. If the highest is a small fraction of the limit, you may be paying to hold more than you need, and a smaller limit would do.
Our guide to business loan interest rates and fees explains how to compare total cost without chasing a headline number.
Can you get a line of credit with property security or past credit problems?
Yes, security can widen the options, but private mortgage funding is usually structured as a term loan, not a revolving limit. If you have equity in a property and need money quickly, a second mortgage or a caveat loan is often faster to arrange than a new revolving facility, and bad credit can be considered when the security is suitable.
For defaults, judgments or past ATO debt, read bad credit business loans. A revolving facility from a mainstream lender is the hardest product to win with a damaged record, so a security-led loan is often the practical route.
How do you apply?
The quickest way to find out which product fits is to start your application and say plainly what the money is for and when it comes back. We are a matching service: we help match you with a property-secured option, an unsecured loan, or tell you straight if a revolving facility is the right tool for your case.
Have these ready:
- Recent business bank statements
- Your ABN and how long you have traded
- A figure for the peak gap, with a sentence on when it repays
- Details of any property you could offer as security

If the need is recurring and flexible, a revolving limit may suit. If it is urgent and one-off, a lump sum probably does. The quick application takes minutes, and it is the fastest way to see which of those two your numbers point to. Apply now or ring 03 4059 1829 and we will talk it through.
