Quick answer
A business line of credit is an approved limit your business can draw on and repay as needed, paying for only what you use. Most are unsecured and sized on turnover and bank statements, typically $5,000 to $500,000. Setting one up usually takes a few business days, but once it's in place, drawing funds is almost instant — which makes it the fastest option for recurring cash-flow gaps.
Key points
- An approved limit you draw on and repay as often as needed
- You generally pay only on the amount drawn
- Takes a few business days to set up; draws are then near-instant
- Best for recurring gaps — BAS quarters, seasonal troughs, slow payers
Why the fastest loan is sometimes the one you already have
When owners search for fast business finance, they’re usually in the middle of a crunch. A line of credit is the answer to the next crunch. It’s approved in advance, sits unused until needed, and can be drawn within minutes when a bill lands.
That’s why a line of credit belongs in any serious conversation about speed. The first approval takes a few business days. Every draw after that is close to instant, with no new application, no new documents and no new wait.
How a line of credit works day to day
- You’re approved for a limit — say, enough to cover a typical BAS payment and a fortnight of wages.
- You draw what you need when a gap appears, usually by transferring into your business account.
- You repay as cash comes in, often with a minimum repayment each period.
- The limit frees up again for the next gap.
You generally pay interest or fees on the amount drawn, not the full limit, though some facilities also charge a line fee for keeping the limit available. Ask for the costs in dollars for a realistic usage pattern — for example, drawing a set amount for six weeks each quarter — and compare them with the loan cost calculator.
When a line of credit beats a term loan
| Situation | Better fit |
|---|---|
| Quarterly BAS payments that squeeze cash every time | Line of credit |
| Customers on 30–60 day terms while wages are weekly | Line of credit |
| Seasonal trough before a busy period | Line of credit |
| One-off equipment purchase | Term loan |
| Paying out an ATO debt in one hit | Term loan or secured loan |
| A deadline this afternoon with no facility in place | Unsecured loan or caveat loan |
The pattern is simple: recurring, variable gaps suit a line of credit; one-off, fixed needs suit a loan.
What lenders assess
Most non-bank business lines of credit are unsecured and assessed on:
- Business bank statements — typically six to twelve months, showing deposits, conduct and existing repayments.
- Time trading — usually at least six to twelve months.
- Turnover — the limit is sized to what your deposits can support.
- Existing debt and ATO position — considered case by case.
Some lenders also offer lines of credit secured by property, which can support higher limits. If your need is larger than your turnover supports unsecured, ask about that option.
Thinking about a facility for the next BAS quarter? Enquire now, well before the due date — setting up ahead of the crunch is the whole point.
Timing it around the BAS calendar
For most quarterly lodgers, BAS is due on 28 October, 28 February, 28 April and 28 July. Monthly lodgers pay on the 21st of the following month. If those dates regularly squeeze your cash, apply for a line of credit a few weeks before the next one, not the week of. Our BAS and GST funding page explains how owners use facilities to smooth tax payments, and the business cash calendar lists the key 2026–27 dates.
Using a line of credit well
- Treat the limit as a buffer, not income. If the balance never comes down, the facility is funding a structural problem, not a timing gap.
- Repay from the event that caused the draw. Drew for BAS? Repay as the next month’s receipts arrive.
- Watch the fees on an unused limit. A limit far bigger than you need can cost money for nothing.
- Review it yearly. As turnover grows, a larger limit may be available; as needs change, a smaller one may be cheaper.
An illustrative example
A Sydney IT services company bills clients monthly on 30-day terms but pays contractors fortnightly. Every quarter, BAS lands in the same week as a large contractor run. A line of credit sized to cover both is set up in early October. The company draws for three weeks around each BAS date and repays as client invoices clear, paying only for the weeks the funds are used. Illustrative only.
Questions to ask before you accept a limit
Lines of credit vary more than most owners expect. Before signing, get clear answers to these:
- What does it cost to hold the limit? Some facilities charge a monthly or annual line fee whether you draw or not. Others charge only when funds are used.
- What’s the minimum repayment? Some require a set percentage of the balance each month; others require the balance to be cleared within a period.
- Can the limit be reduced or cancelled? Understand the circumstances in which the lender can change the facility, and how much notice you’d get.
- How are draws made? Online transfer, card, or request to the lender? How long does each take to reach your account?
- Is there a review date? Many facilities are reviewed annually. Know what the lender will look at, so you can keep the file healthy in between.
A good facility is boring: it sits there, it’s used for genuine timing gaps, it’s repaid, and nobody thinks about it until the next quarter.
Get a facility in place before you need it
The quickest money is the money that’s already approved. There’s no credit check when you enquire, your details stay with one team instead of being sent to a queue of lenders, and a real person will help you size a limit that fits how your cash actually moves. Accurate turnover and trading details on the form help us get that size right first time. See if you qualify for a line of credit.
Frequently asked questions
How does a business line of credit work?
A lender approves a limit. You draw funds when you need them, repay when cash comes in, and draw again. Interest or fees usually apply to the amount used rather than the full limit, though some facilities also have line fees.
Is a line of credit the same as an overdraft?
They're similar. An overdraft is attached to your transaction account; a line of credit is often a separate facility you transfer from. Non-bank lines of credit are commonly assessed on bank statements rather than full financials.
How fast can I get a business line of credit?
Establishing the facility usually takes a few business days. The speed advantage comes afterwards: once approved, you can draw funds almost immediately, without a new application each time.
What limit will I get?
Limits are sized on turnover, deposit patterns and existing commitments, typically between $5,000 and $500,000. A lender may start lower and increase the limit as you use and repay the facility well.
