Key Takeaways
- Working capital is your “breathing room”: It is the cash and liquid assets you have available to cover your bills, wages, and materials before you get paid.
- Positive vs. Negative: Positive working capital means you can pay your bills today; negative means you are relying on future (uncertain) income to cover past expenses.
- The “Ideal Ratio”: For most Australian trade businesses, a working capital ratio between 1.2 and 2.0 is considered healthy.
- Late payments are the silent killer: Australia’s slow-payment culture makes working capital even more critical for tradies who fund materials upfront.
- Actionable Fixes: You can improve your position by invoicing faster, negotiating better supplier terms, and keeping a dedicated cash buffer.
In the world of trade, we talk a lot about “Profit” and “Cashflow.” But there is a third metric that often determines whether a business thrives or folds during a quiet month: Working Capital.
Think of working capital as the “fuel in the tank.” You might have a high-performance truck (your business profit), but if you don’t have fuel in the tank to get to the next job site, you aren’t going anywhere. For tradies, understanding this concept is the difference between a business that feels like a struggle and one that feels in control.
What Exactly Is Working Capital?
In plain English, working capital is the difference between what you own (that can be turned into cash quickly) and what you owe (that needs to be paid soon).
The simple formula is:
Current Assets – Current Liabilities = Working Capital
- Current Assets: Cash in the bank, outstanding customer invoices (Accounts Receivable), and stock or materials on hand.
- Current Liabilities: Supplier bills (Accounts Payable), upcoming wages, superannuation, and tax obligations (GST/PAYG).
If you have $100,000 in assets and $70,000 in liabilities, you have $30,000 in working capital. This is your safety net.
Why Tradies Need More “Fuel” Than Other Businesses
Many retail businesses get paid the moment they provide a service. Tradies, however, often operate on a “lag.”
- You pay for the materials upfront.
- You pay your team (or yourself) weekly.
- You finish the job and send the invoice.
- You wait 14, 30, or even 60 days to get paid.
During that entire cycle, your working capital is what keeps the lights on. If a major client pays late and you don’t have enough working capital, you might struggle to buy materials for the next job or—worst case—miss a payroll.
How to Measure Your Health: The Working Capital Ratio
A quick way to check your business health is to divide your assets by your liabilities.
- Ratio below 1.0: You are in the “red zone.” You don’t have enough liquid assets to cover your current debts.
- Ratio between 1.2 and 2.0: You are in the “green zone.” You have enough to cover your bills and still invest in growth.
- Ratio above 2.0: You might actually have too much cash sitting idle. It might be time to invest in better gear, more staff, or paying down long-term debt.
3 Simple Ways to Improve Your Working Capital
1. Speed Up Your “Invoicing Cycle”
The faster you send an invoice, the faster it becomes cash. Many tradies wait until the weekend to do their paperwork. By then, you’ve already been “lending” money to your client for five days. Use job management software to invoice the second the tools are back in the van.
2. Negotiate with Suppliers
If your clients pay you on 30-day terms, but your suppliers want payment in 7 days, you have a 23-day “cash gap.” Try to negotiate 30-day terms with your main suppliers to align your outgoings with your incomings.
3. Review Your “Work in Progress” (WIP)
Money tied up in half-finished jobs is a drain on working capital. Aim to finish jobs and hit “milestone” payments as quickly as possible. Don’t let a job sit at 90% completion for two weeks; that final 10% is where your liquid cash is hiding.
Final Thoughts
Working capital isn’t a “set and forget” number. It fluctuates with every job you take on and every bill you pay. By keeping an eye on your ratio and tightening your invoicing, you ensure that your business has the “fuel” it needs to survive the slow months and seize the big opportunities.
