Understanding timing, liquidity, and value in Australian business sales

When preparing to sell a business, owners tend to focus on revenue, profit, and valuation multiples. But one of the most powerful drivers of business value — and one of the most scrutinised by buyers — is cash flow. A business that generates reliable, predictable cash flow is typically worth more than a business with the same profit but unpredictable or delayed payments. Healthy cash flow will highlight value to a buyer.

This article explores how cash flow works, how it affects valuation, and which industries tend to have strong versus weak cash flow positions. It also provides a practical breakdown of different business models to help owners understand how their cash cycle may impact buyer appeal.

What Is Cash Flow and Why Does It Matter?

Cash flow refers to the movement of cash in and out of a business. It is not the same as profit. A business can be profitable on paper but struggle with cash flow if payments are delayed, inventory ties up funds, or expenses are front-loaded. Strong cash flow means money comes in quickly and reliably, allowing the business to pay staff, suppliers, and taxes on time - and to reinvest or distribute surplus cash.

From a buyer's perspective, cash flow is a key indicator of financial health and risk. Buyers often adjust valuation expectations based on how easily and quickly the business converts sales into actual cash.

How Cash Flow Works and How It Impacts Business Valuation

How Cash Flow Impacts Business Valuation

Buyers value businesses based on risk-adjusted return. A business with smooth, predictable cash inflows is seen as lower risk and may command a higher multiple of earnings or EBITDA (how to calculate EBITDA). On the other hand, if the business experiences seasonal cash shortfalls, relies on customer credit terms, or has unpredictable payment cycles, the buyer may reduce their offer or insist on vendor financing or earn-out terms to offset the risk.

Cash flow issues can also impact deal structure. A buyer may request working capital adjustments, retention clauses, or longer due diligence periods to verify cash conversion reliability. EBITDA valuation methods may vary by industry.

Industries with Strong Cash Flow

Businesses with the following characteristics tend to have strong cash flow:

Customers pay upfront or at point of sale
Limited inventory or stock holdings
Low accounts receivable
Short payment cycles from sale to cash

Examples include:

Retail (POS-based): Supermarkets, bottle shops, and convenience stores collect cash or card payments immediately with low debtors.
Gyms and fitness studios: Membership-based models collect recurring payments monthly in advance.
Childcare centres: Government subsidies are paid regularly, and parents typically pay fortnightly.
eCommerce with prepaid sales: Online stores receive funds before goods are shipped, particularly when using platforms like Shopify with instant settlement.
Professional services with prepaid retainers: Consultants, marketing agencies, or legal advisors that invoice monthly in advance.
Self-service laundromats: 100 percent upfront payment, minimal overhead, and no receivables.

Industries with Weak or Lumpy Cash Flow

Industries with long project timelines, large upfront costs, or delayed payment cycles tend to suffer from cash flow strain. Common characteristics include:

Invoicing after delivery or project completion
Extended customer credit terms (30 to 90+ days)
High inventory costs or upfront material purchases
Irregular or seasonal revenue

Examples include:

Construction and trades: Progress payments are often delayed, and costs are incurred weeks or months before revenue is received.
Wholesale distribution: Often supplies to retail clients on 30 to 60 day terms, while buying inventory upfront.
Manufacturing: High raw material costs and production lead times require significant working capital.
Recruitment agencies: May wait up to 90 days to be paid by large clients after placing a candidate.
Advertising and creative agencies: Long project cycles and delays in client approvals impact invoicing timelines.
Event businesses: Revenue is concentrated in short seasonal bursts, with long lead times and upfront costs.

Improving Cash Flow Before Sale

Business owners looking to sell should take steps to improve cash flow well before going to market. This may include:

Negotiating shorter payment terms with customers
Reducing accounts receivable days through better collections processes
Introducing upfront payments or deposits for services
Switching to subscription or recurring models where possible
Selling slow-moving stock and reducing inventory holdings
Improving cash flow reporting and forecasts

These improvements not only make the business easier to run - they can also lift valuation and reduce buyer hesitation.

Cash flow is often the difference between a business that looks good on paper and one that attracts strong offers. Buyers will analyse how quickly revenue turns into cash, how much working capital is required, and how predictable the cash cycle is. By improving your business's cash flow before sale, you can increase certainty, reduce buyer risk, and ultimately achieve a better price and deal structure.

If you are planning to sell, ask your accountant or broker to help you review your cash cycle and prepare a strategy to strengthen your cash position ahead of going to market.
