Cash flow pressure is one of the most common reasons promising startups stall. A business can be winning customers, growing revenue and even showing an accounting profit, yet still struggle to pay wages, suppliers, tax obligations or essential operating costs at the right time.

Strong cash management gives founders more control over decisions. It helps you see pressure early, protect the working capital needed to keep operating and invest in growth with greater confidence.

Start by treating cash flow as a leadership priority

Cash management is not simply an accounts task to revisit at BAS time. For a startup, it should be a regular management discipline that informs hiring, pricing, marketing spend, stock purchases, product development and funding decisions.

This matters particularly for companies. Directors need to understand the company’s financial position and take reasonable steps to ensure it does not continue incurring debts when it cannot pay them as they fall due. Good records, current reporting and realistic forecasts are practical safeguards, not administrative extras.

The aim is not to eliminate every uncertainty. Startups operate in changing conditions. The aim is to create enough visibility to make a considered decision before cash becomes a crisis.

The following seven practices can help.

Build a realistic rolling cash forecast

1. Forecast cash in and cash out separately

A profit and loss report tells you whether revenue exceeds expenses over a period. A cash forecast answers a different question: when will money actually arrive, and when will it leave the bank account?

Prepare a rolling cash forecast that covers the coming weeks and months, then update it regularly. Include expected customer receipts, payroll, rent, supplier payments, software subscriptions, loan repayments, tax obligations, superannuation, insurance, inventory and planned capital purchases.

Where possible, use dates rather than broad monthly estimates. For example, an invoice issued near the end of a month may not be collected until well into the following month, while wages and supplier payments may be due much earlier.

A useful forecast should show:

  • opening bank balance;

  • expected customer receipts by likely payment date;

  • committed and likely expenses by payment date;

  • amounts set aside for tax and employee-related obligations;

  • expected financing inflows or repayments;

  • the projected closing cash balance for each period; and

  • a cautious scenario if sales are delayed or costs increase.

The ATO notes that cash flow projections can help businesses identify potential shortfalls, plan tax payments and major expenses, and provide useful information to lenders.

2. Test the forecast against less favourable scenarios

A forecast based only on best-case sales assumptions can create false comfort. Test what happens if a major customer pays late, a sales campaign underperforms, a supplier requires payment sooner than expected, or an important team member needs to be replaced.

This is not pessimism. It is preparation.

Consider maintaining three views:

  • Base case, using the most likely sales and payment assumptions.

  • Downside case, allowing for slower receipts or higher costs.

  • Growth case, showing the cash required if sales rise faster than expected.

The downside case is often the most valuable. It identifies the point at which the business would need to reduce discretionary expenditure, improve collections, renegotiate supplier terms or arrange funding.

Improve the speed and reliability of customer payments

3. Make it easy for customers to pay promptly

Many cash flow problems are not caused by a lack of sales. They arise because businesses wait too long to invoice, invoices are unclear, or no one follows up overdue accounts.

Put a simple receivables process in place from the beginning. Issue invoices promptly, ensure they are accurate, include clear payment terms and offer practical payment methods. If your service is recurring, consider whether automated billing, deposits, progress payments or subscription-style arrangements suit the way you deliver value.

For project-based businesses, avoid funding a long engagement entirely from your own cash reserves where possible. A well-designed proposal may include an upfront deposit and staged invoices linked to genuine project milestones.

Regularly review:

  • invoices due soon;

  • invoices that are overdue;

  • customer disputes or approval delays;

  • concentration risk, where a small number of customers represent a large share of expected receipts; and

  • whether payment terms still reflect the value and risk involved in the work.

A startup does not need to be aggressive to be disciplined. A polite reminder before an invoice falls due can be more effective, and less awkward, than a difficult conversation weeks later.

4. Price for the cash cycle, not just the sale

Pricing decisions should reflect more than labour, materials and competitor rates. They should also account for the time between delivering work and receiving payment.

A lower-margin job with prompt payment may support cash flow better than a higher-margin job with extended payment terms, high delivery costs and a material risk of delay. Equally, rapid sales growth can consume cash if each new customer requires substantial upfront delivery, stock or staff costs.

Review whether your pricing and contract terms cover:

  • upfront setup or onboarding work;

  • payment milestones;

  • changes in scope;

  • late-payment processes;

  • supplier cost increases;

  • customer-specific delivery costs; and

  • the working capital required before you are paid.

A founder may see a full sales pipeline as a sign that cash pressure will soon ease. It may, instead, mean the business needs more cash to fulfil the work. Your forecast should make that distinction visible.

Control spending without starving the business

5. Separate essential spending from optional spending

Startups need to invest, but not every expense deserves the same level of commitment. Create clear categories for spending so you can see what must continue, what supports growth and what can be paused if conditions change.

Essential costs may include payroll, key suppliers, insurance, core systems and statutory obligations. Growth spending may include carefully measured marketing, recruitment, product development or professional support. Optional spending may include subscriptions that are underused, premature upgrades or projects without a clear commercial return.

A practical approach is to review recurring expenditure at set intervals. Ask:

  • Is this cost still used?

  • Does it support revenue, compliance or essential operations?

  • Is there a lower-cost alternative?

  • Can the commitment be renegotiated?

  • What would be the operational effect of pausing it?

Cost control should not become indiscriminate cutting. Reducing expenditure that directly supports profitable sales, customer service or compliance can create a larger problem later. The objective is to direct cash towards the activities that matter most.

6. Manage suppliers, stock and commitments actively

Supplier relationships can be an important source of flexibility, particularly where a startup is growing quickly. Communicate early if you need to discuss delivery schedules, order quantities or payment arrangements. Surprises tend to damage trust more than an early, well-managed conversation.

If your business holds stock, review how much cash is tied up in slow-moving items. Overstocking can make a business look busy while quietly draining its bank account. Conversely, running stock too lean can lead to lost sales or expensive last-minute purchasing.

Before committing to major purchases, new leases, long software contracts or additional headcount, consider the full cash impact. The initial purchase price is only part of the decision. Ongoing support, implementation, training, maintenance and financing costs can all affect the forecast.

Protect money needed for tax and employment obligations

7. Treat tax and employee obligations as planned cash commitments

Money received from customers is not always fully available for business spending. Depending on your circumstances, part of it may need to fund GST, income tax, PAYG withholding, superannuation or other obligations.

This is especially important for startups experiencing uneven income. A strong sales month can create a false sense of surplus if the related tax and employment obligations have not been recognised in the cash plan.

Set up a clear process to estimate and quarantine amounts for upcoming obligations. Some businesses use a separate bank account for this purpose, while others maintain a clearly identified reserve within their cash management system. The method matters less than consistency and visibility.

For businesses registered for GST, registration and reporting requirements need to be monitored as turnover changes. The law requires an enterprise to register when its GST turnover meets the applicable registration turnover threshold, subject to the rules that apply to that entity.

Good record keeping also supports better cash decisions. Accurate, current records make it easier to track what is owed, reconcile bank movements, prepare BAS information and identify expenses or liabilities that may otherwise be missed. The ATO identifies cash flow management, reliable records, appropriate accounting systems and professional advice as common features of businesses that are operating well and meeting their obligations.

Use funding deliberately, not as a substitute for a plan

External funding can help a startup bridge a timing gap, invest in a proven opportunity or withstand a temporary disruption. However, funding should support a sound business model, not conceal an ongoing cash shortfall.

Before taking on finance, consider:

  • what the funds will be used for;

  • whether the expected return is realistic;

  • when repayments begin;

  • whether repayments still work under a downside scenario;

  • any security or personal guarantees required; and

  • whether equity funding, debt, customer deposits or slower spending would be more appropriate.

For example, a software startup wins a larger customer and needs to hire implementation staff before the first milestone invoice is due. Its forecast shows a temporary gap, rather than a permanent trading loss. The founders may decide to use a short-term funding option after comparing the cost of finance with the expected margin and the risk of delayed customer payment.

That same funding would be much riskier if the forecast showed that the business was consistently spending more than it could reasonably collect. In that situation, the priority may be to revisit pricing, costs, customer terms or the operating model.

For company directors, persistent poor cash flow, overdue obligations and difficulty paying suppliers are warning signs that require prompt attention. ASIC encourages directors to monitor solvency actively, investigate financial difficulty, obtain suitable advice where needed and act in a timely way.

Turn cash management into a regular routine

The strongest cash management systems are usually simple enough to be followed consistently. A weekly review may be appropriate for a fast-moving startup, while a less volatile business may need a different rhythm.

At each review, compare actual bank movements and receipts against the forecast. Investigate material differences rather than simply updating the numbers. If sales receipts are consistently late, costs are regularly higher than expected or tax reserves are being used for operating expenses, treat that as information requiring action.

Cash management works best when it is connected to everyday decisions. Before approving a new hire, campaign, equipment purchase or customer proposal, ask what it does to the forecast and how much flexibility remains if assumptions change.

Build growth on a stronger cash foundation

A healthy cash position does more than help a startup pay bills. It gives the business options. It allows founders to negotiate from a position of greater strength, invest in the right opportunities and respond to setbacks before they become urgent.

The seven practices are straightforward: forecast regularly, test downside scenarios, collect promptly, price for the cash cycle, control commitments, reserve money for obligations and use funding with a clear purpose. Applied consistently, they can make growth more sustainable.
