It sounds impossible, but it happens every day: a business with growing sales and healthy profits suddenly cannot pay its bills. The culprit is almost always poor cash flow management.
Profit vs Cash Flow
Profit is what is left after expenses are subtracted from revenue on paper. Cash flow is the actual movement of money into and out of your bank account. You can make a sale today, record it as profit, but not receive payment for 60 days. Meanwhile, wages, rent and suppliers still need paying now.
Common Causes of Cash Flow Problems
- Late-paying customers: long payment terms or slow payers tie up your money.
- Rapid growth: buying stock and hiring staff before revenue arrives.
- Too much inventory: cash sitting on shelves instead of in the bank.
- Seasonal sales: busy months followed by quiet ones.
- Unexpected costs: equipment failures, tax bills or price rises.
- Underpricing: margins too thin to absorb surprises.
Build a Cash Flow Forecast
A cash flow forecast predicts the money coming in and going out over the next 3 to 12 months. Create a simple spreadsheet with:
- Your opening bank balance
- Expected cash in each month (when customers will actually pay)
- Expected cash out each month (wages, rent, suppliers, tax, loans)
- The closing balance, which becomes next month’s opening balance
Update it monthly. A forecast shows you a shortfall weeks in advance, giving you time to act.
Ways to Speed Up Cash Coming In
- Invoice immediately when work is done, not at the end of the month.
- Shorten payment terms, for example from 30 days to 14.
- Take deposits or staged payments for larger projects.
- Offer small discounts for early payment.
- Accept card and online payments to make paying easy.
- Follow up overdue invoices promptly and politely, with automated reminders.
Ways to Manage Cash Going Out
- Negotiate longer payment terms with suppliers.
- Buy stock in smaller, more frequent batches.
- Lease rather than buy expensive equipment where it makes sense.
- Review subscriptions and recurring costs every quarter.
- Schedule large payments for after major customer payments arrive.
Keep a Cash Buffer
Just as individuals need an emergency fund, businesses need a cash reserve. Aim for at least three months of fixed operating costs. A buffer turns a potential crisis into a manageable inconvenience.
Plan for Tax
Tax bills catch many owners off guard. Move a fixed percentage of every payment into a separate tax account so the money is ready when the bill arrives.
Know Your Financing Options Before You Need Them
Arrange an overdraft facility or line of credit while your business is healthy, not when you are already struggling. Invoice financing can also release cash tied up in unpaid invoices, though it comes at a cost.
Final Thoughts
Cash is the oxygen of a business. Profit shows whether your business model works, but cash flow determines whether you survive long enough to benefit. Forecast regularly, get paid faster and keep a buffer, and you will avoid one of the most common reasons businesses fail.
