Working capital is one of the most important financial concepts for any business owner to understand - yet many Australian SME owners have never calculated it. This guide explains what working capital is, why it matters, and how specialist finance can help you manage it.
What is working capital?
Working capital is the difference between your current assets (cash, receivables, stock) and your current liabilities (accounts payable, short-term debt). It measures your business's ability to meet its short-term obligations.
The formula is simple:

Why working capital matters
A business can be profitable on paper but have negative working capital - meaning it cannot pay its bills as they fall due. This is how profitable businesses go under. Working capital is the difference between a business that survives a slow month and one that doesn't.
Common causes of working capital pressure in Australian SMEs include:
- Long debtor payment terms (clients taking 30–90 days to pay)
- Seasonal revenue fluctuations
- Rapid growth (paradoxically, fast-growing businesses often have the worst working capital)
- Excess stock tied up in inventory
- Short supplier payment terms
How a business overdraft helps working capital
A business overdraft or line of credit is the most common tool Australian SMEs use to manage working capital gaps. Rather than turning away work or defaulting on supplier payments during a tight period, you draw on your overdraft to bridge the gap - and repay it as your receivables come in.
Example: A marketing agency completes a $80,000 project in January. The client pays on 45-day terms - so payment arrives in mid-March. Meanwhile, the agency has staff wages of $25,000 due each fortnight. A $50,000 overdraft covers the gap and is repaid in full when the client pays.
Working capital finance vs long-term debt
Working capital finance - overdrafts, lines of credit - is designed to be short-term and revolving. It's not the right tool for long-term capital investment. Using a working capital facility to fund a 3-year equipment purchase is expensive and inefficient. A business loan with a fixed term is better suited to that purpose.
Match the finance to the need: short-term, revolving needs = overdraft. Long-term, specific investment = business loan.
How to improve your working capital position
- Reduce your debtor days - invoice faster, follow up sooner
- Extend supplier payment terms where possible
- Reduce excess inventory
- Increase your overdraft limit before you need it
- Consider invoice financing for large, slow-paying debtors
