Your business can report a profit and still run short of cash because income and expenses are not always recorded when money moves through the bank. Customers may pay after you have paid staff or bought stock. Equipment purchases, loan repayments and owner distributions can also use cash without appearing as the same period’s operating expenses.
The question is not only “are we profitable?” It is where is the cash tied up, when will it be released, and what must be paid before then? That matters for consultancies, retailers, distributors, manufacturers and other growing UK SMEs.
Profit and cash answer different questions
Profit measures income and costs under the accounting policies used for the period. Cash flow measures money received and paid. The British Business Bank explains that profitable businesses can experience cash problems, including when they incur costs before customers pay.
Take a consultancy completing a project in March and collecting its invoice in May. Staff salaries and subcontractor bills may fall due in March and April. The revenue and associated profit do not make the customer’s cash available sooner. For a distributor, buying additional inventory can absorb funds before that stock is sold and collected.
Worked example: £20,000 operating profit, £25,000 cash outflow
This fictional monthly example is in £000 and is not a client result. It begins with operating profit before interest and tax. Depreciation is the only non-cash operating adjustment assumed. Working-capital movements and other payments shown capture all cash changes in the example; a real reconciliation needs the relevant VAT, tax and other balances too.
| Movement | Cash effect | Explanation |
|---|---|---|
| Operating profit | 20 | Accounting operating result for the month. |
| Add depreciation | +5 | Expense included above, without a current cash payment. |
| Increase in trade receivables | −25 | More income remains uncollected at month end. |
| Increase in inventory | −10 | Additional money is tied up in stock. |
| Increase in trade payables | +5 | Some supplier costs remain unpaid. |
| Operating cash before interest and tax | −5 | 20 + 5 − 25 − 10 + 5. |
| Tax paid | −4 | Cash settlement in this month. |
| Interest paid | −1 | Financing cost paid in cash. |
| Equipment purchased | −8 | Capital expenditure, separate from depreciation. |
| Loan principal repaid | −3 | Repayment of borrowing, not an operating expense. |
| Dividends paid | −4 | Owner distribution, not an operating expense. |
| Net change in cash | −25 | Total cash movement under these assumptions. |
Opening bank cash £60,000 − cash outflow £25,000 = closing bank cash £35,000.
A profitable month has still reduced the available balance. This example explains the movement; it does not establish the cash buffer the business needs.
The useful next step is to investigate the drivers. Are receivables rising because sales increased, customers are paying later, invoices are disputed, or the revenue itself needs review? Is stock being bought for confirmed demand, seasonal requirements or an optimistic forecast? A single total cannot answer those questions.
Where cash gets trapped in different businesses
Consultancies and agencies
Unbilled work, milestone approvals, subcontractors paid before collection and project overruns. Review work completed, invoice readiness and project contribution.
Retailers and distributors
Stock purchased ahead of demand, returns, slow-moving lines and supplier deposits. Link ordering decisions to stock ageing and actual sell-through.
Manufacturers and service firms
Materials, work in progress, equipment and labour commitments can precede receipts. Track production or delivery milestones alongside cash dates.
Growth can make the gap larger
Suppose customers consistently pay after 60 days while key suppliers expect payment after 30 days. More sales may require a larger receivables balance, more stock and more delivery capacity. The business can grow revenue and profit while also increasing the amount it must fund.
Do not assume that borrowing alone fixes the problem. A timing gap, excess inventory and loss-making work need different responses. Finance can provide headroom where suitable, but it does not repair a weak commercial model or guarantee access to funding.
What to check before committing to more spending
- Reconcile the opening position. Confirm bank balances, restrictions, committed payments and the actual availability of facilities.
- Review collections invoice by invoice. Check due dates, disputes, approvals and the evidence behind promised receipts.
- Review stock and unbilled work. Identify slow-moving items, unfinished work and amounts that may not turn into cash at their recorded value.
- Build a weekly cash view. Schedule actual expected receipts and payments, including payroll, tax, debt service and large commitments.
- Test a realistic downside. Move an uncertain receipt, assess the lowest cash point and assign actions to named people.
- Review the trading economics. Check pricing, margins, delivery effort and whether growth is creating cash needs the plan has not funded.
Our 13-week cash forecast example shows how a delayed payment changes the lowest bank balance. A cash forecasting engagement can turn your own records into an agreed weekly process.
Keep a short monthly cash action pack
Bring together operating performance, aged debtors, stock or unbilled work, payment commitments and the next cash low point. Record actions such as invoice resolution, agreed supplier discussions, stock reduction or changes to discretionary spending. Update assumptions when evidence changes and explain the variance to the previous forecast.
If finance information arrives late or no one owns the decisions, fractional CFO support can help define responsibilities and connect the cash forecast to wider management decisions. If there is a risk the company cannot meet obligations when due, seek prompt professional advice on the specific position; a profitable P&L is not a substitute for that assessment.
Frequently asked questions
Can a profitable business run out of cash?
Yes. Income may be recognised before customers pay, while stock, wages, tax, equipment, debt repayments and distributions can use cash. Review the timing and causes rather than relying on profit alone.
Does higher revenue always improve cash flow?
No. Growth can increase receivables, stock and delivery commitments before receipts arrive. The effect depends on margins, payment terms, operating capacity and the cash needed to support the growth.
Is borrowing the answer to a cash shortfall?
It depends on the cause and realistic funding availability. A temporary timing gap, excess stock and persistently weak margins need different responses. Borrowing does not itself repair the underlying economics.
What should I review first?
Confirm available cash and committed payments, review customer collections and stock or unbilled work, and build a near-term cash forecast with clear assumptions and owners.
How is this different from a profit forecast?
A cash forecast schedules bank receipts and payments by expected date. A profit forecast measures income and expenses under the accounting basis used. Both are useful, but they answer different questions.
