Operating Cash Flow: Why EBITDA Is Not Enough
EBITDA is an earnings measure. Operating cash flow is what the business actually generates. The gap between them is where industrial businesses lose value — quietly, and usually for a long time before it shows up in a liquidity problem.
A business can report strong EBITDA and still be tightening credit lines, delaying payments and struggling to fund capital expenditure. When that happens, the problem is not the P&L. It is the operating cycle.
The gap between EBITDA and operating cash flow is almost always in the operating cycle.
Operating cash flow — EBITDA adjusted for working capital movements and maintenance capital — tells you whether earnings are real. The businesses with the strongest cash conversion manage the operating cycle as a commercial discipline. The businesses with the weakest conversion do not.
Debtors are slow — revenue is booked but not collected; cash conversion cycle extends with every sale on unmanaged terms
Inventory is uncontrolled — stock reflects purchasing history, not demand; working capital is trapped in product not turning
Pricing is leaking — discounts and freight allowances erode the margin that EBITDA appears to show
Creditors are paid too quickly — available supplier terms are not used; cash leaves before it needs to
What happens is the finance review shows EBITDA on track while the cash position tightens — and the operating cycle problem goes undiagnosed until it becomes a banking or transaction event.
The gap between EBITDA and operating cash flow is not a reporting problem. It is an operating cycle problem.
EBITDA looks acceptable. Cash is tight. The board is asking why. Working capital is growing faster than revenue. The credit facility is being used more than it should be.
This is not a strategy problem. It is an operating cycle problem — specific, diagnosable, and fixable when the operating cycle is managed as a commercial discipline rather than a finance function.
Revenue is booked but not collected. The cash conversion cycle extends with every sale that trades at terms the business is not actively managing. As volume grows, debtor management typically weakens. Collections become a finance task rather than a commercial accountability.
Uncontrolled Inventory
Stock levels reflect purchasing history, not demand. Working capital is trapped in product that is not turning. The result is a business that looks profitable on the P&L and cash-poor on the balance sheet — with 20–30% of held stock typically unmoved in 90 days in businesses that have grown without active inventory discipline.
Pricing Leakage
Discounts, rebates, freight allowances and ad-hoc concessions erode the margin that EBITDA appears to show. Pricing discipline is the first operating cycle lever — and the one most consistently left unmanaged as businesses scale.
Creditor Terms Not Used
Most businesses pay suppliers on the supplier’s preferred schedule. Available creditor terms are rarely negotiated after initial setup. Cash leaves before it needs to — reducing the float available for the operating cycle.
What This Usually Signals
The gap between EBITDA and operating cash flow signals that the operating cycle is being managed passively. Working capital is growing faster than the business is managing it. The board is seeing EBITDA but not the cash implications.
When this pattern persists across two or more periods, it typically indicates that the management team does not have the operating cycle disciplines, reporting infrastructure or commercial accountability to close the gap from the inside.
When to Engage
EBITDA looks acceptable but cash is consistently tighter than it should be
Working capital has grown faster than revenue for two or more consecutive periods
The management team cannot explain the debtor, inventory or creditor position at the transaction level
A board or investor is questioning cash generation — and may need an operating partner to resolve it
A transaction event is placing operating cash flow conversion under a diligence lens
Collections are owned by the commercial team, not the finance team. Debtor days are reported weekly. Escalation paths are defined. Every sale that trades beyond standard terms is a management decision, not a default.
Inventory Positioned to Demand
Stock purchasing is driven by demand data, not history. Fast-moving lines are protected. Slow-moving positions are reduced. The cash trapped in inventory is quantified and managed as a financial position — not left to accumulate.
Creditor Terms as a Cash Reserve
Available supplier terms are renegotiated and used. Payment timing is optimised for the cash cycle. This is one of the lowest-cost, highest-impact cash flow interventions available to most industrial businesses.
Operating Cash Flow as a Board Metric
Operating cash flow sits alongside EBITDA in the board reporting pack. The gap between them is explained at the operating cycle level — by debtor days, inventory turn and creditor terms — not just at the P&L level.
The gap between EBITDA and operating cash flow compounds quietly — through slow debtors, uncontrolled inventory, pricing leakage and unused creditor terms — until it surfaces as a liquidity constraint or a transaction risk.
Working capital and cash flow improvement addresses the specific operating cycle disciplines that close the gap between EBITDA and cash — debtor management, inventory positioning, creditor terms and pricing discipline.

The cash conversion rate is one of the first metrics examined in any transaction or PE diligence process — and one of the most reliable indicators of operating cycle quality.
Pricing leakage is frequently the least visible component of the EBITDA-to-cash gap — the accumulated cost of undisciplined discounting that shows up as margin compression before it shows up in cash.
When the operating cash flow gap requires embedded leadership to resolve, an operating partner mandate provides the inside presence to run operating cycle disciplines at pace.
EBITDA that does not convert to cash creates a sell-side readiness problem — buyers will apply a quality-of-earnings discount to earnings that do not convert to free cash flow.
When the issue requires P&L accountability at the executive level, an interim CEO mandate provides embedded leadership to diagnose and correct the commercial and operating cycle causes.
