Growth has a habit of arriving before the cash does. You win a bigger contract, but you need to pay for stock, wages and materials weeks before the invoice is paid. You take on more staff to meet demand, but payroll lands on the same date every fortnight regardless of when customers settle. That gap — between money going out and money coming in — is where working capital finance earns its place.
This article walks through the main working capital options available to Australian businesses, what each is suited to, and the trade-offs to weigh up. It’s general information to help you frame the conversation — the right fit depends on your business, and a broker can help you compare what’s actually available to you.
What “working capital” actually means
Working capital is the money your business needs to cover day-to-day operations — stock, wages, rent, suppliers — while you wait for revenue to come in. A profitable business can still run short of working capital if its cash is tied up in unpaid invoices or inventory. Working capital finance bridges that timing gap; it’s about cash flow, not necessarily about a lack of profit.
It’s worth being clear on the purpose before choosing a product. Funding a short-term timing gap calls for a different structure than funding a long-term asset or a permanent increase in operating scale.
The main options
Here’s how the most common working capital products compare. None is universally better — they solve different problems.
| Option | Best suited to | Worth knowing |
| Business overdraft | Smoothing short-term, recurring cash flow gaps | Interest on the drawn amount only; flexible but rates can be higher |
| Line of credit | Ongoing, variable funding needs | Draw and repay as needed up to a limit; discipline matters |
| Unsecured business loan | A defined one-off need with fast access | No asset security; assessed on cash flow; often quicker to settle |
| Secured business loan | Larger amounts, longer terms | Backed by property or assets; typically lower rate, more documentation |
| Invoice finance | Businesses with large unpaid B2B invoices | Advances cash against receivables; cost tied to invoice value |
| Trade / supply finance | Importers and stock-heavy businesses | Funds suppliers directly; bridges the order-to-sale gap |
Overdraft vs line of credit
Both give you flexible access to funds you can draw on and repay as needed, and with both you generally pay interest only on what you use. An overdraft is attached to your transaction account and tends to suit short-term, recurring smoothing — covering the dip before a big receipt lands. A line of credit is usually a separate, often larger facility for ongoing variable needs. The flexibility is the strength and the risk: because the money is always there, it takes discipline to use it for genuine working capital rather than as a permanent crutch.
Unsecured vs secured business loans
An unsecured business loan doesn’t require you to put up property or assets as security, which means faster access and no asset on the line — but lenders price for that risk, so rates are often higher and the assessment leans heavily on your cash flow and trading history. A secured loan, backed by property or business assets, typically comes with a lower rate and longer term, suited to larger or longer-term funding. The trade-off is more documentation and an asset at stake. Which suits you depends on the amount, the timeframe, and what security you’re willing and able to offer.
Invoice and trade finance — unlocking cash that’s already yours
If your business issues large invoices to other businesses and waits 30, 60 or 90 days to be paid, invoice finance can advance a portion of that money now rather than later. It’s tied to your receivables, so it tends to scale with your sales. Trade or supply finance works at the other end — funding your suppliers so you can fulfil orders before the resulting sales convert to cash. Both can suit businesses whose growth is constrained by timing rather than demand.
The current cost-of-doing-business backdrop
Borrowing costs for businesses move with the broader rate environment. The RBA raised the cash rate three times across the first half of 2026 — February, March and May — to 4.35%, then held it there at its June meeting (RBA, 16 June 2026). Higher rates have already flowed through to many business facilities, which makes the structure and pricing of working capital finance more worth reviewing than it was a couple of years ago. Nobody can tell you where rates head next — but you can make sure the facility you’re using today is still the right one.
Questions to ask before you borrow
- Is this a short-term timing gap, or a permanent step up in operating scale?
- How predictable is the revenue that will repay it?
- Do I need flexibility (draw and repay) or a fixed lump sum?
- Am I willing and able to offer security in exchange for a lower rate?
- What’s the total cost of the facility — not just the headline rate, but fees and terms?
Your call — and how to make it
Working capital finance is a tool, and the right tool depends on the job. The mistake worth avoiding is reaching for whatever’s quickest rather than what fits — a long-term need funded with a short-term product, or an expensive facility used out of habit. A broker’s value here is range: we work with 70+ lenders, from major banks to specialist business lenders, so you can compare structures and pricing across the market and choose with the full picture in front of you.
