A business line of credit gives your business a pool of approved capital that’s ready whenever you need it. You draw what you need, repay it as cash comes in, and draw again, all without reapplying. FastBiz Loans arranges business lines of credit from $10,000 to $250,000, with decisions in as little as 4 hours. Think of it as a standing “yes” for the everyday ups and downs of running a business, and for the opportunities that don’t wait.
Here’s how a line of credit works in practice, how it compares with an overdraft and a loan, how your limit is set, and the habits that keep it working for you.
How does a business line of credit work?
A line of credit works like a reusable limit. You’re approved for a maximum amount, draw any part of it when you need to, and the amount available tops back up as you repay. You generally pay only for what you’ve drawn, not for the unused limit.
The easiest way to see it is over a few months. Here’s an illustrative business with a $50,000 limit:
| Month | What happens | Drawn | Still available |
|---|---|---|---|
| March | Nothing drawn — the limit sits ready | $0 | $50,000 |
| April | Draws $20,000 for a supplier’s bulk-buy offer | $20,000 | $30,000 |
| May | Draws $10,000 to cover the quarterly BAS | $30,000 | $20,000 |
| June | Stock sells through; repays $25,000 | $5,000 | $45,000 |
| July | Repays the remaining $5,000 | $0 | $50,000 |
No new application in April or May, and the full limit is back in July, ready for the next season. That’s the point of a revolving facility.
Line of credit, overdraft or business loan: which fits?
All three can fund working capital, but they suit different patterns. Here’s a plain comparison:
| Business line of credit | Business overdraft | Small business loan | |
|---|---|---|---|
| How funds arrive | Draw into your account as needed | Your transaction account goes below zero | One lump sum up front |
| Repayments | Flexible, based on what you’ve drawn | Balance moves with daily banking | Regular scheduled instalments |
| Where it sits | A separate facility | Attached to your bank account | A separate loan account |
| Typical provider | Banks and non-bank lenders | Usually your own bank | Banks and non-bank lenders |
| Best for | Recurring or unpredictable needs | Day-to-day timing gaps | One-off purchases and projects |
The key practical difference from an overdraft: a line of credit usually sits apart from your everyday account, so drawing on it is a deliberate choice rather than something that happens when a direct debit lands. Many owners find that separation makes it easier to manage. And because it’s not tied to your transaction account, you don’t need to move your banking to get one.
If you’re torn between a revolving limit and a lump sum, our comparison of a line of credit vs a business loan works through the decision, and a small business loan may suit better if the need is a single, defined purchase.
How is your credit limit set?
Your limit is set mainly from your business’s turnover and what your bank statements show about how cash moves through your account. The range is $10,000 to $250,000; where you land within it depends on your situation.
Here’s what lenders weigh up:
- Monthly revenue. Limits are commonly sized in proportion to turnover. Steady, growing deposits support a higher limit.
- Consistency. A business with reliable monthly income is lower risk than one with big swings, even if the average is the same.
- Account conduct. Frequent overdrawn days, dishonoured payments or repeated missed direct debits count against you.
- Existing commitments. Other finance repayments reduce how much new limit is comfortable.
- Time in business. Six months or more of trading is the usual starting point.
Limits over $150,000 also need financial statements, so allow time to gather them from your accountant. You can check the basics in a couple of minutes with our eligibility checker.
A tip many owners find useful: start with the limit you genuinely need, use it well, and ask for a review as your business grows. A history of drawing and repaying responsibly is the strongest case you can make.
Great uses for a line of credit (and poor ones)
A line of credit shines when needs come and go. It’s less suited to things that take years to pay back.
Where it works well:
- Seasonal stock. Buy ahead of Christmas, EOFY sales or harvest, then repay as it sells. See seasonal cash flow planning for ways to map your peaks.
- BAS, GST and PAYG timing. Keep tax obligations current when a quarterly bill lands before customers pay. Our guide to managing BAS and tax cash flow has more.
- Supplier discounts. Pay early or buy in bulk when a supplier offers a better price.
- Wages in lumpy months. Cover payroll when a big client pays late.
- Quick opportunities. A one-off order, a clearance deal, an event booking — say yes without waiting.
Where something else usually fits better:
- Long-life equipment. Equipment finance can be matched to the working life of the asset.
- A big one-off project. A fit-out or expansion with a fixed budget suits a lump-sum loan.
- Ongoing losses. If the business spends more than it earns every month, a line of credit delays the problem rather than solving it.
Who is a business line of credit best suited to?
A line of credit suits established businesses whose costs and income don’t line up neatly month to month. If you can picture a regular moment when money goes out before it comes back in, a revolving limit is probably worth a look.
Some typical patterns:
- Retailers and online stores that buy stock weeks before it sells, especially ahead of peak trading periods.
- Trades and construction businesses that pay for materials and wages before a progress claim or final invoice is paid.
- Wholesalers and distributors that want to take up supplier discounts for early payment.
- Hospitality venues managing quieter months between busy seasons and events.
- Professional services firms covering payroll while waiting for clients on monthly billing cycles.
- Tourism operators in places like the Whitsundays or the Snowy Mountains, where revenue is concentrated in a few months of the year.
It’s less suited to a brand-new business, because limits are set from trading history, and to anyone who would treat the limit as extra income. The owners who get the most from a line of credit use it as a tool with a clear start and finish for each draw.

Good habits that keep your line of credit working for you
A line of credit is only as useful as the way you run it. These habits help keep costs down and your limit available:
- Draw for a specific purpose, and know where the repayment will come from before you draw.
- Repay as soon as the incoming cash arrives, rather than letting a balance linger.
- Aim to bring the balance back to zero, or close to it, at regular points in your cycle.
- Keep a small unused buffer for genuine surprises.
- Don’t use the limit to make repayments on other debt.
- Check your balance alongside your cash flow forecast each month.
- Ask for a limit review when turnover has grown, not when you’re under pressure.
How fast can I get a business line of credit?
Decisions can come back in as little as 4 hours for straightforward applications. The quickest path is simple: complete the online enquiry, connect your business bank account through a secure read-only link, upload your photo ID, and be ready to take the lending specialist’s call. Many lenders now read bank statements digitally, including through Consumer Data Right open banking, which is a big part of why assessment is fast.
What slows things down: statements arriving late, a limit over $150,000 needing financial statements, or unanswered questions. Once approved and signed, your limit is ready to draw.
Example scenario — illustrative only. Priya runs a Fremantle homewares boutique. Her sales jump every November and December, but stock needs to be ordered in September. She sets up a line of credit in winter, when there’s no pressure. In September she draws to pay for her Christmas stock, and through December she repays from sales. By January the balance is back to zero and the limit is ready for next year.
What you’ll need to apply
- 3–6 months of business bank statements, shared securely online
- Photo ID and your ABN or ACN
- Financial statements for limits over $150,000

Questions we get asked
How is a line of credit different from a business loan?
A business loan gives you one lump sum with a fixed repayment schedule. A line of credit gives you a limit you can dip into and repay repeatedly, so the amount you owe goes up and down with your needs. Loans suit one-off purchases; a line of credit suits recurring or unpredictable costs.
Do I pay anything if I don't use my line of credit?
You generally only pay for the funds you draw, although some facilities have account-keeping or establishment costs. Your lending specialist will set out exactly how your facility is priced before you sign, and every facility is priced on your business's individual situation.
How quickly can I draw funds once my line is set up?
Once your facility is active, drawing is typically done online and funds usually move quickly into your business account. That's the main appeal: the approval work is done in advance, so the money is ready when a need or an opportunity comes up.
Can my limit be increased later?
Often, yes. If your revenue grows and you manage the facility well, you can ask for a limit review. Consistent repayments and a healthy account history are the strongest arguments for a higher limit.
Is a line of credit secured or unsecured?
Many business lines of credit are unsecured, typically with a director guarantee, and assessed on your revenue and bank statements. Larger limits may call for security. Your lending specialist will explain which applies to your situation.
Can I use a line of credit to pay my BAS?
Yes, many businesses use a line of credit to keep BAS, GST and PAYG payments on time when a quarterly bill lands before customer payments do. It works best when you repay the draw as the incoming cash arrives.
