The Liquidity Blind Spot

Merixa Insights · Cash Flow Visibility

Why profitable firms still face cash crises — and the two structural issues that create the gap between what the P&L reports and what the bank account holds.

There is a conversation that happens in growing businesses with uncomfortable regularity. The management accounts show a healthy margin. Revenue is ahead of the prior year. The pipeline is strong. And yet there is a cash pressure — a tightening that does not match the financial picture, that arrives without warning, and that the current reporting cannot readily explain.

For most founders, that moment produces a specific kind of confusion: if the business is profitable, where is the cash? The answer to that question originates from two structural issues that most financial reporting, as it is currently structured in midsize organisations, does not make visible until the bank account has already made them unavoidable.

Issue one — growth consuming cash faster than it creates it

Profit is an accounting measure. It records value earned in a period, irrespective of when that value is received as cash. A business can invoice successfully, recognise revenue accurately, report a positive margin — and still find its bank account under pressure, because the cash attached to that profit has not yet arrived, or has been consumed by the working capital demands of its own growth before it does.

This is the operating condition of most businesses scaling with any meaningful pace. As revenue grows, the debtor book grows with it. The lag between invoicing and collection — which may have been manageable at lower volumes — becomes a structural cash drain as the business issues more invoices, at larger values, into a collection cycle that has not been actively managed. Simultaneously, cost commitments made to support the growth — headcount, infrastructure, supplier terms — are paid in advance of or concurrent with the revenue they are funding. The business is, in accounting terms, performing. In liquidity terms, it is consuming the cash its own success is generating faster than that cash is arriving.

The precise mechanism is the cash conversion cycle — the number of days between cash going out to fund operations and cash coming back from clients. A business with a 60-day cash conversion cycle on £4m of annual revenue has an indicative £660,000 permanently tied up in its own operational cycle at any given point (where Working Capital = Revenue x Cash Conversion Cycle in days). When that cycle extends by ten days through slower collection, the additional working capital requirement is approximately £110,000 — an amount that appears nowhere in the P&L but drains the bank account with the same effect as a direct cost of that size.

A profitable business is not inherently a cash-safe one. Growth consumes cash before it creates it — and the faster the growth, the wider that gap becomes before the reporting makes it visible.

Issue two — debt service invisible in the profitability measure

The second issue amplifies the first and operates entirely beneath the P&L line that most founders use to judge the health of their business. Loan repayments, revolving credit facility drawdowns and repayments, hire-purchase commitments, and director loan repayments all reduce the cash available to the business without affecting the profitability measure leadership is monitoring. A business reporting £300,000 EBITDA while servicing £180,000 of annual debt repayment obligations has a true discretionary cash position of £120,000 before working capital movements — a position materially different from the one the P&L suggests.

This invisibility is not a reporting failure in the conventional sense. The debt service is correctly accounted for. The problem is that it sits below the line most founders track and is rarely presented alongside the profitability measure in a way that makes the combined cash position legible without financial training. The consequence is a leadership team making commercial commitments — new hires, capital expenditure, supplier contract extensions — against a profitability picture that overstates the actual discretionary cash the business holds. The tightening arrives not because the business is performing poorly but because the cash available to fund its performance was never as visible as the profit suggested.

Together, these two issues — growth-driven working capital expansion and debt service invisibility — produce the pattern most founders eventually experience: a profitable business that periodically cannot operate with the financial confidence its own numbers appear to warrant. The diagnostic work begins with understanding how wide the gap between the two currently is — and which of the two issues is the primary driver of the tightening the business is experiencing or approaching.

Where to look first

Does your current reporting show a forward cash position — not what is in the account today, but what will be there in 8, 12, and 16 weeks, based on known commitments and expected receipts?
Do you know your average debtor days across the client base — and whether that figure has moved in the last two reporting periods?
Can you identify from current reports how much cash is tied up in work completed but not yet billed — and what commercial change would release it?
When you last experienced a cash pressure, was the cause identified before it arrived — or only understood after the bank balance made it unavoidable?

Profitability earns the right to grow. Cash flow visibility is what allows that growth to continue without interruption. The diagnostic work begins with understanding precisely how wide the gap between the two currently is — and which of the two structural issues is sitting inside it.
