A business can have customers, receive orders, issue invoices and even make a profit while still struggling to pay its employees, suppliers and monthly expenses.
This happens because profit and cash flow are not the same thing.
Profit measures the financial performance of a business over a period. Cash flow measures the actual movement of money into and out of the business. When money leaves the business before customers pay, the business experiences a cash-flow gap.
For South African SMEs, this challenge is particularly important. Many businesses operate with limited cash reserves while waiting 30, 60 or even 90 days for customers to settle invoices. During that waiting period, rent, salaries, stock purchases, transport, electricity and other expenses still need to be paid.
Late payments and working-capital shortages are major challenges for local businesses.
Why profitable businesses run out of cash
Consider a small construction company that wins a R300,000 project.
The company purchases materials, pays workers and completes the work. It invoices the customer for R300,000, expecting payment within 30 days.
However, the customer takes 90 days to pay.
During those 90 days, the construction company must continue paying its suppliers, employees, transport costs and other operating expenses.
The project may be profitable, but the business could run out of money before receiving payment.
This is why business owners need to manage both profitability and cash availability.
The six cash-flow systems every SME should have
1. Cash-flow forecasting
Know how much money is expected to enter and leave your business over the next 13 weeks. This helps you identify potential shortages before they happen.
2. Invoice and payment management
Issue invoices immediately, use clear payment terms and follow up consistently. Do not allow outstanding invoices to become forgotten debts.
3. Working-capital management
Understand how much money is required to keep your business operating while waiting for customer payments.
4. Expense control
Monitor operating expenses, supplier costs, subscriptions, salaries and other recurring commitments. Identify unnecessary spending before it becomes a financial burden.
5. Customer collections
Introduce a structured process for reminding customers about outstanding invoices, resolving payment queries and escalating overdue accounts.
6. Contract and growth planning
Before accepting a large order or contract, calculate the cash required to deliver it. More sales do not automatically mean more available cash.
The difference between cash-flow problems and profitability problems
It is important to identify the actual problem before looking for finance.
| Business situation | Likely issue |
|---|---|
| Customers pay late, but sales are profitable | Cash-flow timing |
| Stock sells below its total cost | Profitability |
| Monthly expenses exceed gross profit | Operating profitability |
| Large orders require upfront purchases | Working-capital pressure |
| Business borrows every month to pay ordinary expenses | Possible structural losses |
| Customers owe money but the business cannot pay suppliers | Receivables and liquidity problem |
Borrowing can help bridge a temporary timing gap. It cannot permanently fix a business that consistently spends more than it earns.
