More small businesses fail from running out of cash than from a lack of profit. You can be winning work, sending invoices, and growing revenue, and still find yourself unable to cover next week's wages if the timing of money in and money out isn't managed. Here's how Perth business owners can stay ahead of it.
Why does cash flow matter more than profit?
Profit is calculated over a period and includes income you've earned but haven't necessarily been paid for yet. Cash flow is the real-time movement of money into and out of your bank account. A business can show a healthy profit on its year-end accounts and still miss payroll in March because a big invoice was paid 60 days late. Managing the business day to day means watching cash flow at least as closely as the bottom line.
What are the most common causes of cash flow problems?
Slow-paying customers are the biggest culprit, closely followed by overstocking inventory, underpricing jobs so margins are too thin to absorb delays, and seasonal dips in revenue that aren't planned for. A less obvious cause is treating GST and PAYG withholding amounts sitting in the bank as available funds — that money belongs to the ATO, not the business, and spending it creates a shortfall that shows up the moment a BAS is due.
How can invoicing practices improve cash flow?
Send invoices the moment work is complete rather than batching them at month end, and make payment as easy as possible with card, BPAY, or direct debit options built into the invoice. Shortening payment terms from 30 days to 7 or 14 days, where your market allows it, and following up on overdue accounts within a few days rather than weeks both materially shrink the average time between doing the work and being paid for it.
What about deposits and progress payments?
For project-based or trade businesses, requesting a deposit before starting work and progress payments at agreed milestones spreads the cash inflow across the job rather than leaving the entire amount sitting in a single invoice at the end, which is the riskiest point for a payment dispute or delay.
Should a small business use a cash flow forecast?
Yes — a simple rolling 12-week forecast listing expected income and expenses week by week is one of the highest-value habits a small business owner can build. It surfaces shortfalls while there's still time to act: delaying a discretionary purchase, following up an invoice earlier, or arranging a short-term facility, instead of discovering the gap when a direct debit bounces.
How does GST and BAS timing affect cash flow?
GST you collect from customers isn't business revenue — it's the ATO's money, held temporarily in your account until your BAS is lodged and paid. Businesses that spend this as ordinary cash flow are usually fine until the BAS falls due, at which point they're short by exactly the amount they've spent. Transferring the GST component of each sale into a separate savings account as you invoice is a simple habit that removes this risk almost entirely.
What tools help manage cash flow day to day?
Cloud accounting software such as Xero gives real-time visibility over unpaid invoices, upcoming bills, and bank balances, and can generate short-term cash flow forecasts automatically from your existing data. Pairing this with a simple due-date reminder — our BAS due date calculator is a quick way to keep lodgement dates in view — takes most of the guesswork out of when money needs to be set aside.
