Cash Flow vs Profit

Profit is not cash

Profit is the difference between revenue and expenses on paper. Cash flow is the actual money moving in and out of your bank account. A business can look profitable and still run out of cash.

Why the gap exists

• Customers pay later than you record the sale.
• You pay suppliers, salaries, and taxes before customers pay you.
• Inventory ties up cash until it is sold.
• Loan repayments reduce cash but are not full expenses.

Why it matters

• Cash shortages are the most common reason small businesses fail.
• Healthy cash flow lets you pay obligations on time and handle surprises.
• It gives you room to invest and negotiate from a stronger position.

Simple formula

Monthly Cash Flow = Cash In − Cash Out

Practical example

A consultant invoices €10,000 in January (profit on paper) but clients pay 60 days later. In January, salaries, rent, and software still cost €4,000 in real cash. January cash flow = 0 − 4,000 = −€4,000, even though the books show a profit. The business needs a cash buffer to survive until invoices are paid.

Practical tips

• Track cash inflows and outflows weekly, not only monthly.
• Send invoices fast and follow up on late payments.
• Keep a cash buffer that covers several months of fixed costs.
• Plan large purchases around your cash cycle, not only profit.
