A business overdraft is one of the most flexible finance products available to Australian small businesses - but many business owners don't fully understand how they work, or assume they won't qualify. This guide covers everything you need to know.
What is a business overdraft?
A business overdraft - also called a business line of credit - is a revolving credit facility attached to your business. Once approved, you receive a credit limit (up to $500,000) that you can draw from at any time, repay, and draw again. Unlike a traditional loan, you don't receive a lump sum - you access funds on demand and only pay interest on what you actually use.
Think of it as a financial buffer that sits behind your business bank account. When you need cash - whether for stock, wages, a supplier invoice, or an unexpected expense - you draw it down. When revenue comes in, you repay it. The limit refreshes automatically as you repay.
Key point: With a business overdraft, you only pay interest on the amount you have drawn down - not on your full approved limit. If your limit is $100,000 but you've only used $20,000, you pay interest on $20,000.
How does a business overdraft actually work?
Here's a simple example. Imagine your business has a $80,000 overdraft facility:
- On Monday, you draw $30,000 to pay a supplier invoice. You now have $50,000 available.
- Over the next two weeks, a large client payment arrives. You repay $30,000. Your full $80,000 is available again.
- Next month, you need $15,000 for stock ahead of a busy period. You draw it down. And so on.
Repayments are typically made weekly and are automatically debited from your nominated business account. Interest is calculated daily on your drawn balance.
Business overdraft at a glance
What can you use a business overdraft for?
Business overdrafts can be used for almost any legitimate business purpose. The most common uses include:
- Cash flow gaps - bridging the period between invoicing clients and receiving payment
- Stock and inventory - buying ahead of demand or taking advantage of bulk pricing
- Paying suppliers - meeting supplier payment terms without straining operating cash
- Wages and payroll - covering payroll during slow periods
- Marketing campaigns - funding growth initiatives without depleting reserves
- International supplier payments - paying overseas suppliers directly when linked to an OFX Business Account
- Seasonal shortfalls - drawing down during slow periods and repaying when revenue picks up

What does a business overdraft cost?
Costs for a business overdraft typically include:
- Interest - charged daily on your drawn balance at a fixed rate. The rate depends on your credit profile, turnover, and the lender.
- Weekly service fee - a small ongoing fee charged from the date of settlement, regardless of whether you have drawn funds.
- Registration fee - may apply for facilities above $150,000 where a caveat or mortgage is registered over property.
