A business line of credit is one of the most useful funding structures available to Australian SMBs, and one of the most misunderstood. It is not a loan you draw once and repay. It is an approved limit you can dip into repeatedly as the business needs it.
That flexibility makes it well suited to businesses with uneven income, seasonal peaks, or ongoing timing gaps between paying costs and getting paid. It is less suited to funding a single large purchase, where a term facility is usually cleaner and cheaper.
Blackcube Capital helps operators work out whether a revolving limit or a term facility actually fits the problem in front of them. If you want that assessed quickly, start an enquiry here.

How a business line of credit works
A lender approves a maximum limit. You draw against it when you need funds, repay when money comes in, and the available balance recovers as you repay. As long as the facility remains in good standing, you can draw again without submitting a fresh application each time.
This is the core difference from a term loan. A term loan gives you a lump sum on day one and a fixed schedule to repay it. A revolving limit gives you access, and you decide when and how much to use. If you are weighing the two directly, our comparison of a business loan versus a line of credit goes through the trade-offs.
What it costs drawn and undrawn
Interest is generally charged only on the balance you have actually drawn, not on the full approved limit. That is the main appeal: an unused facility sitting in reserve is far cheaper to hold than an unused term loan you are already repaying.
That said, revolving facilities frequently carry establishment fees, ongoing line or facility fees, and sometimes a minimum drawdown. Those charges apply whether or not you use the limit, so the honest cost of a line of credit is the interest on what you draw plus the fees on what you hold.
Which businesses a line of credit suits
It tends to work well where the funding need is recurring but unpredictable in size and timing. Covering payroll between large customer payments, restocking ahead of a busy season, or absorbing a slow month are all classic uses.
It works less well when the need is a single defined purchase with a known cost, because you end up paying facility fees for flexibility you are not using. For businesses whose main issue is the timing gap itself, our guide to cash flow loans for small business covers the alternatives.
What lenders assess before setting a limit
Because a revolving facility gives ongoing access rather than a one-off advance, lenders look closely at consistency. They want to see that the business generates enough regular income to bring the balance back down, not just enough to service interest.
The points below carry the most weight in that assessment. The limit offered is often lower than the amount requested for exactly these reasons, so it helps to understand them before applying.
- Average monthly turnover across recent trading, not peak months
- How consistently the account runs in credit
- Frequency of dishonours, overdrawn periods or missed direct debits
- Existing facilities and total commitments already in place
- Industry, seasonality and the reliability of your customer payments
- Whether past drawdowns on any prior facility were repaid down
Where lines of credit go wrong
The most common problem is treating a revolving limit as permanent working capital. If the balance never comes back down, the facility has quietly become long-term debt at short-term pricing, and the flexibility you paid for is gone.
The second is sizing the limit against the best trading months rather than the quiet ones. A limit set against a strong quarter can be uncomfortable to service in a slow one. Sizing against realistic turnover is more useful than maximising the number, and our guide to how much funding you can get based on turnover explains how lenders approach that calculation.
Frequently asked questions
Do I pay interest on the full limit of a line of credit?
Generally no. Interest is charged on the drawn balance rather than the approved limit, although facility or line fees may still apply to the limit itself whether you use it or not.
Can I use a line of credit for ongoing working capital?
It can be used that way, but if the balance never reduces, the facility is effectively long-term debt priced as short-term funding. A term facility is often cheaper where the need is permanent.
How is a limit decided?
Lenders typically size a limit against average monthly turnover, account conduct and existing commitments. The offer is often lower than the amount requested because consistency matters more than peak months.
Is a line of credit harder to get than a term loan?
It can be. Ongoing access represents more risk to a lender than a single advance, so consistent trading and clean account conduct carry more weight than they might on a term facility.
