Quick answer
A business overdraft lets your transaction account go below zero, up to an agreed limit, so you can keep paying bills during short cash flow dips. It's traditionally a bank product, often reviewed annually and sometimes secured by property. If a bank won't offer one, a business line of credit from a non-bank lender can do a very similar job.
Key points
- Attached to your business transaction account.
- Used for short dips, not long-term funding.
- Banks review limits regularly and may reduce or cancel them.
- A line of credit is the closest non-bank alternative.
- Type
- Revolving, attached to transaction account
- Typical lender
- Banks
- Security
- Sometimes property, sometimes none
- Alternative
- Business line of credit
What exactly is an overdraft?
An overdraft is permission to spend more money than you have in your business transaction account, up to a set limit. If your balance is $5,000 and your overdraft limit is $50,000, you can keep paying suppliers and wages until the account reaches minus $50,000. When customers pay, the balance moves back towards positive.
It’s one of the oldest business finance products in Australia, and in many ways one of the simplest. It sits quietly behind your account, ready when you need it.
Why are overdrafts harder to get than they used to be?
Banks have become more selective about overdrafts. Common reasons owners miss out include:
- the bank wants property as security and the owner doesn’t want to (or can’t) offer it,
- the business is young or has uneven trading,
- there’s an ATO debt or a recent credit issue,
- the bank’s appetite for small business lending in that industry has shifted.
If you’ve hit one of those walls, our guide on what to do after being declined by a bank covers the options.
Overdraft vs line of credit vs working capital loan
| Overdraft | Line of credit | Working capital loan | |
|---|---|---|---|
| Where it lives | Your transaction account | Separate facility | Separate loan |
| Revolving? | Yes | Yes | Usually no (lump sum) |
| Typical lender | Bank | Bank or non-bank | Bank or non-bank |
| Best for | Short dips | Recurring gaps | A defined need |
For most businesses that can’t get a bank overdraft, a business line of credit from a non-bank lender is the nearest replacement. You transfer money into your account when needed and repay it as cash comes in. For one-off needs, a working capital loan may be simpler.
How do banks review overdrafts?
Overdrafts are often reviewed annually. The bank looks at your financial statements, how the account has been run, and whether the limit is still appropriate. An account that bounces between positive and negative is healthy. An account that sits near the limit for months suggests the overdraft has become permanent funding, which concerns banks.
If your overdraft is being reduced or cancelled, it’s worth exploring alternatives before the change takes effect. Send us an enquiry and we’ll show you what else is on the shelf.
Using an overdraft well
- Treat it as a buffer for short dips, not a long-term loan.
- Move the account back towards positive regularly.
- Don’t use it to fund big purchases; use equipment finance or a term loan instead.
- Keep your bank informed if trading conditions change.
What else is business overdraft called?
Lenders, accountants and search engines don’t all use the same words. You’ll also see this entry described as Overdraft facility and Bank overdraft. In our A–Z index every one of those names points back to this page, so whichever term you searched, you’ve landed on the same thing. If a lender uses a name you don’t recognise, ask them to describe how the security, the term and the repayments work; that tells you far more than the label.
Where does it sit in the directory?
This entry lives on the cash flow and unsecured shelf. It’s most often used for cash flow and working capital, and the security usually involved is whatever suits the deal, from nothing at all to property. It usually involves a little more paperwork and assessment than the quickest options, so start early. Its closest neighbours are:
- Business line of credit — A limit you draw on, repay and draw again — interest only on what you use.
- Cash flow loans — Sized on turnover and bank statements to smooth out the gap between bills and income.
- Unsecured business loans — No property on the line — typically $5,000 to $500,000 for trading businesses.
- Short-term business loans — Borrow for weeks or months to cover a specific, time-limited need.
To compare all of them at once, filter the Loan Finder by purpose and security.
Common mistakes to avoid
- Starting with the product instead of the purpose. Decide exactly what the money must achieve, then choose the structure that fits it.
- Not comparing secured and unsecured options. The same need can often be met either way; the right answer depends on amount, credit and timing.
- Under-estimating the total cost. Ask for the full amount repayable in dollars, including every fee, before you compare offers.
- Applying everywhere at once. Multiple applications can leave a trail of credit enquiries. One well-prepared enquiry is better.
- Leaving it until the last minute. Facilities are easier to arrange while trading is strong, not in the middle of a crunch.
What should I ask before signing up for business overdraft?
A short list of questions saves a lot of regret. Put these to any lender or specialist before you commit:
- Which structures did you consider for me? A good specialist explains why one option beats the others for your situation.
- What’s the total cost in dollars? Compare like with like across secured and unsecured offers.
- What security or guarantees are needed? Know exactly what’s on the line before you sign.
- How are repayments timed? Match frequency to how money comes into your business.
- What happens if things change? Ask about early repayment, top-ups and hardship options.
If an answer is vague, ask again or ask for it in writing. Good lenders are happy to explain their terms clearly.
Need a buffer that’s actually available?
Whether you’re looking for a first overdraft, a bigger limit or a replacement after a bank pulled back, a quick enquiry is a good first step. There’s no credit check when you enquire, and we don’t fling your details at every lender in the country. One specialist works it out with you.
Please give us accurate figures for turnover and the limit you need. Good information leads to a good match. Start your enquiry.
Frequently asked questions
Why did my bank reduce my overdraft?
Banks review overdrafts periodically. A limit can be reduced if trading has weakened, the account has been run near the limit for long periods, tax debts have appeared or the bank's own appetite has changed.
Is an overdraft cheaper than a line of credit?
It can be, particularly from a bank with property security. But availability and conditions vary, and many businesses can't get one. Compare the full cost of each option.
Can I get an overdraft without property?
Some banks offer small unsecured overdrafts to established customers. For larger limits, banks often want property security.
What happens if I go over my limit?
Payments may be dishonoured and fees charged. Repeated excesses can damage your relationship with the bank and lead to a review.
