How to Manage Cash Flow for a Small Business

Cash flow is the lifeblood of any small business. Profitable businesses can still fail if they run out of cash to pay suppliers, wages or rent on time. Managing cash flow is not just about counting what is in the bank today; it is about anticipating what will come in and go out over the coming weeks and months, and planning for the unexpected.

Create a Cash Flow Forecast

A cash flow forecast is a simple tool that projects your cash inflows and outflows over a set period, usually 12 months ahead, broken down by week or month. Start with your opening bank balance, then list expected receipts from customers and expected payments to suppliers, employees, tax office and lenders.

Be realistic. If a major customer typically pays late, reflect that in your forecast. If you have seasonal peaks, account for them. Review and update the forecast regularly, at least monthly, so it stays accurate.

Accounting software can generate cash flow reports, but a simple spreadsheet works for many small businesses. The key is to use it consistently, not just create it once.

Invoice Promptly and Follow Up

Late payments are a major cause of cash flow stress. To improve collections:

• Send invoices immediately after delivering goods or services.
• Include clear payment terms, such as 14 or 30 days, and accepted payment methods.
• Offer electronic invoicing and online payment options to make it easy for customers to pay.
• Set up automatic reminders for overdue invoices.
• Follow up personally on large or overdue accounts, and do not be afraid to pause work if payments stop.

If you deal with other businesses, remember that your own payment habits affect their cash flow too. Timely payment builds goodwill and can lead to better terms in future.

Manage Your Outgoings

Review your regular expenses to see where you can negotiate or cut. Common areas include:

• Supplier contracts: ask for bulk discounts or extended payment terms.
• Subscriptions and memberships: cancel unused services.
• Insurance: review your cover annually, but do not underinsure. Our article on commercial property insurance explains what to consider.
• Energy and utilities: see our guide on reducing energy costs for practical tips.

Where possible, align payment dates with your expected receipts. For example, if you invoice on the 1st and get paid around the 15th, try to schedule major payments after the 15th.

Build a Cash Buffer

A cash buffer, ideally enough to cover three to six months of operating expenses, gives you breathing room when sales dip or a large unexpected bill arrives. Building a buffer takes time, so start small. Transfer a fixed amount to a separate savings account each week or month, and treat it as a non-negotiable expense.

If you have debt, consider whether paying it down faster or building cash reserves is the better priority for your situation. High-interest debt usually takes precedence, but having some cash on hand prevents you from relying on credit in an emergency.

Use Credit Wisely

Credit can bridge gaps, but it should not be used to cover ongoing losses. Options include overdrafts, business credit cards, lines of credit and invoice financing. Each has different costs and risks. Before taking on new credit, calculate the total cost and ensure you can repay it from expected cash flow, not just hope.

If you are struggling with existing debts, seek advice early. Our article on redundancy packages touches on employment-related financial obligations that can affect your cash position if you need to restructure your workforce.

Plan for Tax and Super Obligations

Tax and superannuation payments are not optional. Set aside money as you earn it, rather than scrambling when BAS or super due dates approach. A separate bank account for tax obligations can help you avoid accidentally spending that money.

If you are behind on tax, contact the ATO or your tax agent early to discuss payment arrangements. Ignoring the problem usually makes it worse.

Review and Adjust Regularly

Cash flow management is ongoing. Set a routine: review your forecast monthly, check aged receivables weekly, and compare actual results to your projections. Adjust your plans as circumstances change. A business that monitors cash flow closely is far better placed to survive slow periods and take advantage of opportunities when they arise.

Frequently Asked Questions

What is the difference between profit and cash flow?

Profit is what remains after expenses are deducted from revenue, while cash flow is the actual movement of money in and out of your bank account. You can be profitable on paper but still run out of cash if customers pay slowly.

How often should I update my cash flow forecast?

At least monthly, and more often if your business is growing quickly or experiencing volatility. Regular updates keep the forecast useful.

What should I do if I cannot pay a supplier on time?

Contact them before the due date, explain the situation and propose a realistic payment plan. Most suppliers prefer communication over silence and may be willing to negotiate.
