Business lines of credit for established SMEs

When is a line of credit the right tool?

A line of credit earns its place when the business has a gap that opens and closes on a rhythm. Payroll lands before the month’s biggest customer pays. A quarterly BAS falls due in the same week as a stock order. A project business carries costs for six weeks before its first progress claim is paid. In each case, the money is needed briefly and comes back.

That rhythm is what distinguishes a line from a loan. With a term loan you receive a lump sum and repay it on a schedule, whether or not you still need the cash. With a line you draw what you need, when you need it, and the limit becomes available again as you repay. Interest and fees are generally charged on what is drawn rather than on the whole limit, though some facilities carry a line fee on the undrawn portion — read the pricing schedule, not just the headline.

For an established SME, a line works best as one layer in a funding stack. It sits above a core of term debt or equity that funds the permanent working capital, and it absorbs the swing.

How do lenders size an unsecured line?

Without property security, the lender’s comfort comes from the business’s cash flows. That makes the bank statements the centre of the assessment. A lender reading them will look for:

• Scale and regularity of deposits. Turnover drives the limit; consistent weekly or monthly receipts are more persuasive than a few very large ones.
• Balances through the month. Does the account run close to zero before each payroll, or does it hold a buffer?
• Dishonours and returned payments. A handful of dishonoured direct debits can do more damage than a weak quarter.
• Existing repayments. Daily or weekly debits to other lenders reduce capacity and are read carefully.
• Tax conduct. Regular BAS and super payments signal a disciplined operator.

For trading businesses, unsecured and line-of-credit options typically range from $5,000 to $500,000. The RBA noted in its October 2025 Bulletin that the non-bank share of SME lending has increased strongly since the start of 2022, particularly for smaller loans — which is broadly where unsecured lines live.

What does property security change?

A property-backed revolving facility sits within the broader $20,000 to $5,000,000 range for property-secured business lending, using a first mortgage, second mortgage or caveat over residential or commercial property. Three things usually change:

1. The ceiling. Security, rather than bank-statement averages alone, supports the limit.
2. Tolerance for a soft year. A lender with good security can look past one weaker set of accounts if there’s a credible explanation.
3. Review risk. Reviews still happen, but the conversation leans on the security position as well as trading.

The trade-off is the work involved: valuations, title checks and, where there’s an existing mortgage, the first-ranking lender’s position. The property-backed business loan page explains how that plays out.

How much should the limit be?

Too small and the line runs out in the month you need it. Too large and you pay for headroom you never use, and the lender may view a big, idle limit as risk. A practical method:

Step	What to calculate	Illustrative figure
1	Largest forecast cash shortfall in the next 12 months	$420,000 (December stock + payroll)
2	Typical monthly shortfall	$180,000
3	Buffer for a late major receipt	$90,000
4	Suggested limit	About $510,000 — likely a property-backed limit rather than unsecured

Illustrative only; no real business. The working capital cycle calculator will show the underlying funding gap if you haven’t forecast it month by month.

If the number you arrive at is bigger than an unsecured line would typically support, that’s a sign the structure needs property security or a term component. A specialist can tell you quickly which way it’s likely to go — see whether a line of credit fits your numbers.

What habits keep a line healthy?

A line of credit that’s well run makes every future lending conversation easier. The habits that matter most:

• Let it cycle. A line that touches zero or near zero at some point in each quarter demonstrates it’s funding a gap, not a hole.
• Don’t fund assets from it. Vehicles, equipment and fit-outs belong in term finance. See capex funding.
• Track utilisation monthly. A creeping average is an early warning of a stretching cash cycle.
• Keep statutory payments current. BAS, PAYG withholding and super paid on time protect both your standing with lenders and your directors. From 1 July 2026, the ATO requires super guarantee contributions to reach the employee’s fund within 7 business days of payday, which pulls super into the same cash rhythm as wages.

If your bank has already reduced or frozen an existing limit, the options are different — see when the overdraft limit is cut.

Line of credit or working capital term loan?

Question	Line of credit	Term working capital loan
Is the gap recurring?	Yes	No — one-off
Do you want repayment certainty?	Less	More
Will the need shrink over 12–24 months?	Maybe	Yes, on schedule
Is review risk acceptable?	Needs to be	Lower during term

Many businesses end up with both. Our working capital facility page covers the combined approach.

Ready to test a limit?

If your business has a measurable, recurring gap and a clean account history, a line of credit is often the most efficient way to carry it. Tell us the turnover, what the line would fund, and whether property is available.

There’s no credit check when you first enquire. We won’t shop your details to a dozen lenders; a specialist works your file and approaches the funder that suits it. Accurate answers on the form — particularly turnover, existing repayments and security — help us come back with a realistic limit on the first call. Enquire about a business line of credit.
