An owner sees profit in the report but cannot pay a supplier or payroll on time. This is not necessarily an accounting error. Profit measures performance over a period, while cash flow records when money actually arrives and leaves.
A sale may create revenue today although the customer pays in 30 days. A large inventory purchase consumes cash immediately but becomes an expense gradually as goods are sold. A profitable business can therefore suffer a cash gap.
Three reports answer different questions
| Report | Question answered | What it does not show alone |
|---|---|---|
| Profit and loss | Whether the business earned a profit over the period | When customers paid and cash left |
| Cash flow | Where money came from and where it went | Whether each sale was economically profitable |
| Balance sheet | What the business owns and owes on a date | The detailed cause of profit or cash movement |
A high bank balance may be a customer advance or a loan, not earned profit.
Where profit becomes unavailable cash
- Receivables. Revenue and profit exist, but the customer has not paid.
- Excess inventory. Cash has been paid to suppliers and remains tied up in goods.
- Supplier advances. Payment occurs before delivery.
- Investment. Equipment consumes cash now but is expensed over its useful life.
- Loan principal. Cash leaves, but principal repayment is not an operating expense.
- Old liabilities. Current cash pays costs recognised earlier.
Worked example
A company sells UAH 600,000 during the month. Cost of goods sold is UAH 360,000 and operating costs are UAH 150,000, producing UAH 90,000 profit.
Customers pay only UAH 420,000. The company buys UAH 250,000 of additional inventory, repays UAH 40,000 of loan principal and receives a UAH 30,000 advance for a future order.
| Event | Effect on monthly profit | Effect on cash |
|---|---|---|
| UAH 600,000 sale | Revenue of UAH 600,000 | Only UAH 420,000 received |
| Cost of goods sold | −UAH 360,000 | May have been paid in another period |
| New inventory purchase | Not all an expense this month | −UAH 250,000 |
| Loan principal | Does not reduce operating profit | −UAH 40,000 |
| Customer advance | Not yet revenue for an unfulfilled order | +UAH 30,000 |
Profit is positive while cash flow may be negative. The explanation lies in changes to receivables, stock, borrowing and advances.
Working capital
Simplified net working capital = Inventory + Receivables − Trade payables.
When stock and customer debt grow faster than supplier credit, the business needs more of its own cash to support the same revenue.
Why growth can make the problem worse
A growing company buys more stock, hires staff and pays logistics before customers pay. Every new sale can increase profit and deepen the cash gap, particularly with long customer terms and little advance payment.
Measures to check
| Measure | Possible warning | Action |
|---|---|---|
| Receivable days | Customers pay more slowly | Review limits, terms and collection control |
| Inventory coverage | Cash accumulates in stock | Reduce batches and stop excess purchasing |
| Payable days | Suppliers are paid before customers pay | Negotiate terms responsibly |
| Operating cash flow | Core operations do not generate cash | Reconcile the working-capital movements |
| Minimum cash balance | No reserve for mandatory payments | Set a protected liquidity buffer |
Actions for the owner
- Compare profit and cash movement for the same period.
- Build a bridge: profit → receivables → inventory → payables → investment → borrowing.
- Identify overdue receivables and excess stock.
- Do not treat advances and borrowing as distributable profit.
- Introduce an 8–13 week payment calendar.
- Calculate how much cash growth needs before customer payment.
Common mistakes
- Managing from the bank balance. It ignores future obligations.
- Treating every receipt as income. Loans and advances create cash, not profit.
- Treating every payment as an expense. Inventory and principal follow different logic.
- Mixing owner and company money. True liquidity disappears.
- Celebrating revenue growth without working capital. Sales can accelerate a cash shortage.
Finance in Business Reactor
Business Reactor connects sales, payments, purchasing, inventory, debts and documents. Management can move from “where did the cash go?” to the customer, item, payment or obligation responsible.
The next practical tool is a payment calendar that reveals a future negative balance before the cash gap occurs.
Conclusion
Profit is not the cash in the bank. Payment timing, inventory, advances, investment and debt create the difference. Compare profit and loss, cash flow and the balance sheet, then trace the gap to real transactions.
Profit shows whether the model earns; the payment calendar shows whether cash will last until that profit is collected. Business Reactor Finance & Accounting.
