Cash flow mistakes growing businesses commonly make

Strong sales don't always mean healthy cash flow. Here are the most common cash flow mistakes growing Australian businesses make and what to do instead

Strong sales are an encouraging sign. But growth brings its own financial pressures, and cash flow is where those pressures tend to surface first.

The pattern catches many business owners off guard. Revenue is rising, new customers are coming on, and the business looks healthy on paper. Yet there’s not enough cash in the account when wages need to go out or a supplier invoice falls due.

This isn’t a sign the business is failing. It’s a sign the business is growing faster than its financial systems can keep up with. Understanding where the gaps appear, and how to address them, is one of the more useful things a business owner can do at this stage of the growth curve.

Confusing profit with cash flow

Profit and cash flow measure different things, but it’s easy to treat them as if they were the same.

Profit is the figure left over after expenses are subtracted from revenue, as recorded in your income statement. It reflects the economic activity of the business over a period. Cash flow is what’s moving through your bank account in real time.

The two can diverge during periods of growth. A business running on 30-day payment terms invoices a customer for $80,000 in March. That $80,000 shows as revenue in March’s income statement. But if the customer pays on day 45, the cash doesn’t arrive until mid-May. Meanwhile, the business has paid wages, supplier invoices, and rent using money from other sources.

Scale this across a growing customer base and the gap becomes harder to manage. More customers means more outstanding invoices. Larger orders mean higher upfront costs before payment arrives. A business can be producing record profit figures while simultaneously running short on operating cash.

The solution is a cash flow forecast run separately from your profit and loss reporting. A cash flow forecast maps when money is expected to come in and when it’s committed to go out, week by week or month by month. It shows you the cash position of the business at a future point in time, which is different from the profit position.

Businesses that maintain a rolling cash flow forecast, updated regularly, catch problems before they arrive. Businesses that manage by their bank balance or their P&L alone often find out about a cash shortfall only when it’s already a problem.

A simple cash flow projection doesn’t need to be complicated. At its most basic, it lists your expected receipts (based on when invoices are due to be paid, not when they were issued) and your committed outgoings (wages, rent, loan repayments, supplier payments) across a 13-week or six-month horizon. The gap between the two at any given point shows your forecast cash position.

Letting invoice payment terms drift

Payment terms look like a policy decision. In practice, they’re often a negotiation that happens invoice by invoice, and the result drifts further from the stated terms over time.

A business with 30-day payment terms might find that its largest client pays on 45 days as a matter of course, another pays on 60 days, and a third pays only after a follow-up call. The business has effective payment terms of 50-plus days despite its invoices saying 30.

For a growing business with payroll to meet and supplier invoices of its own, the difference between 30-day and 60-day payment terms on a $200,000 invoice book represents $200,000 sitting with customers for an extra month instead of in the business’s account.

The reluctance to follow up firmly on late invoices is understandable, especially with clients that generate substantial revenue. Nobody wants to jeopardise a good customer relationship over a payment timing issue. But the cost of that reluctance adds up, and clients who pay late don’t self-correct without a process that prompts them.

Steps that tighten payment timing:

Invoicing promptly after work is completed or goods are delivered is the starting point. An invoice that takes a week to go out extends your payment terms by a week before the customer has even seen it.

Automating invoice reminders at set intervals before and after the due date removes the awkwardness of manual follow-up. Most accounting software includes this capability. A reminder sent two days before an invoice falls due is routine administration; it’s not a confrontation.

Having a clear escalation process for overdue accounts, with defined steps and timeframes, means late payments get addressed without waiting to see if they resolve themselves.

For businesses where long payment cycles are a structural feature of the industry rather than a problem to be fixed, debtor finance provides an alternative. Debtor finance (sometimes called invoice finance or invoice factoring) allows a business to access a percentage of the value of outstanding invoices before the customer pays. The lender advances the funds now, collects from the customer when payment falls due, and remits the balance minus fees. For businesses waiting 60 or 90 days for payment on large invoices, this can meaningfully improve cash flow without requiring the business to change its customer relationships.

Not understanding your working capital cycle

Working capital is the difference between what a business has in current assets (cash, receivables, inventory) and what it owes in current liabilities (accounts payable, short-term debt). It represents the liquid buffer the business operates from.

Growing businesses often see working capital squeezed in counterintuitive ways. Taking on a large new contract can require buying more materials, hiring more staff, or carrying more inventory well before the associated revenue comes in. A business can win a contract worth twice its previous monthly revenue and face a cash shortfall in the following weeks as it ramps up to deliver.

The cash conversion cycle measures how long it takes for money spent on inputs to return as cash from customers. A business that pays suppliers in 30 days, holds inventory for 45 days, and waits 60 days for customers to pay has a cash conversion cycle of 75 days. That’s 75 days of working capital that needs to be funded.

Shortening any part of this cycle improves cash flow: paying suppliers on longer terms where the relationship allows it, turning inventory faster, or collecting from customers sooner. But there are limits to how far each of these can move, and growing businesses often find the cycle lengthens rather than shortens as order volumes rise.

Monitoring these numbers gives a business owner a more precise picture of where cash flow pressure originates than reviewing a bank balance alone.

Funding growth from operating cash flow when the numbers don’t support it

There’s a logic to funding expansion from the cash the business is generating. It avoids debt, it keeps the structure simple, and it feels like evidence that the business is doing well.

The problem appears when operating cash flow is already stretched. Using cash reserves to buy equipment, fund a fit-out, or hire ahead of demand leaves the business with less buffer for the day-to-day expenses that can’t wait.

A business that draws down its cash reserves to buy a $150,000 machine may find itself scrambling to cover wages or a quarterly tax payment two months later, because the revenue the machine generates hasn’t yet fully flowed through. The machine was a sound investment; the timing created a cash flow problem.

The principle worth applying here is matching the funding type to the purpose. Operating expenses, the day-to-day costs of running the business, are best funded from operating cash flow and short-term facilities. Capital expenditure, assets that will generate returns over a period of years, are better funded with finance structured to match that timeframe.

Equipment finance exists for this purpose. Rather than paying $150,000 upfront for a machine, a business takes out equipment finance and makes monthly payments over three to five years, preserving working capital for operations. The cost is the interest and fees over the term, but the benefit is a business that can keep growing without running its cash reserves into the ground.

The comparison business owners often miss is not between buying with cash and financing the equipment. It’s between having $150,000 in operating cash reserves and having $0 in reserves, and what that difference means for the business’s ability to absorb an unexpected expense or a slow month.

Pricing without accounting for cash timing

Growth sometimes comes with contracts or customers that look profitable on the income statement but create cash flow problems in practice.

A business that wins a large contract requiring $80,000 in upfront materials and labour, to be invoiced on completion in 90 days, has committed $80,000 of cash today against a receivable that won’t arrive for three months. If the business doesn’t have the working capital to carry that gap, the contract becomes a constraint rather than an opportunity.

Volume discounts negotiated with suppliers or passed on to customers can have a similar effect. A 10% discount on a large order sounds favourable until you account for the earlier payment required and the cash that’s locked up in the order while it’s being delivered.

This doesn’t mean avoiding large contracts or volume arrangements. It means pricing and planning them with cash flow timing in mind, not just margin. The question isn’t only whether the contract is profitable. It’s whether the business has the cash to deliver it.

For businesses regularly taking on contracts that require upfront investment before payment, a working capital loan or business line of credit can bridge the gap. These facilities are structured for exactly this purpose: providing short-term liquidity while a project is in progress, to be repaid when the invoice is settled.

Waiting until there’s a crisis to look at financing

A business that approaches a lender because it can’t make next week’s payroll is in a difficult position. Not because the business is in trouble, but because lenders assess applications based on the financial health of the business at the time of application. A business under cash flow stress presents a very different risk profile to a lender than a business that is trading well and planning ahead.

The practical consequence is that businesses in good shape can access more products, at better rates and on better terms, than businesses that are struggling. A business overdraft facility or a business line of credit secured when trading is strong gives the business access to flexible capital that can be drawn on when gaps appear, without requiring a new application under pressure.

A business line of credit in Australia works as a revolving facility with an approved limit. You draw on it when cash flow requires it and repay as receipts come in, paying interest only on the amount outstanding. The facility doesn’t cost anything when it’s not being used. What it costs is the time and effort to set it up, and the best time to do that is when the business doesn’t need it yet.

The same logic applies to other funding products. Invoice finance facilities, equipment finance pre-approvals, and overdraft facilities are all easier to arrange, and come with better terms, when the business can demonstrate consistent revenue and strong trading. Arranging them as part of growth planning rather than as a response to a shortfall is a material advantage.

How a finance broker can help

The financing products available to a growing business are more varied than most business owners realise, and the right combination depends on the specific pressure points in the business’s cash flow cycle.

A finance broker with access to a panel of business lenders can review your situation and identify which products suit your trading pattern, your industry, and your growth plans. For a business with a long debtor cycle, debtor finance may be more useful than a line of credit. For a business investing in equipment, chattel mortgage structures may suit better than a finance lease. For a business about to take on a large contract, a working capital loan timed to the contract start may deliver a better outcome than drawing on an overdraft.

Brokers can also help business owners time financing applications to get the best result. Applying for a business line of credit when revenue is strong and trading history is clear gives the lender the information they need to approve the facility and set terms that reflect the business’s genuine position.

The businesses that manage cash flow well as they grow tend to share a common approach: they treat financing as part of their operating strategy, not as a rescue measure. Getting the right facilities in place, and understanding how to use them, is a practical step that pays off across the full cycle of growth.
