Cash Flow
vs EBITDA

The gap between cash flow and EBITDA is one of the most consistent problems in industrial and distribution businesses. Strong EBITDA with weak cash conversion creates transaction pressure. The gap between reported earnings and cash generation is one of the most important measures of operating quality in any industrial or distribution business. The operational levers for closing this gap — DSO discipline, inventory management and supplier terms — are covered in depth at working capital and cash flow improvement.

The Core Issue

Why EBITDA is not cash

EBITDA is a proxy for operating performance. Cash conversion is the proof of it. The gap between them — the distance between reported earnings and what actually arrives in the bank — reveals the working capital discipline, operational efficiency and capital intensity of the business beneath the headline number.

In industrial, manufacturing and distribution businesses, this gap is structural. It reflects the inherent cash cycle of the business model — but the width of the gap reflects the operating discipline, or absence of it, applied to that cycle.

Buyers, boards and PE firms analyse cash conversion explicitly. A business with strong EBITDA but poor cash conversion trades at a discount to a business of equivalent earnings with strong cash generation. That discount is not arbitrary — it reflects real capital that will need to be deployed to close the gap post-acquisition.

Conversion Drivers

Why cash conversion weakens

Cash conversion deteriorates predictably. The following are the most common structural drivers in industrial and distribution businesses — each measurable, each improvable with the right operating discipline.

DSO Deterioration

Average debtor collection days lengthening beyond agreed payment terms. Each additional day of DSO on significant annual revenue represents material cash tied up in the business. DSO trends are visible months before they become a transaction issue.

Inventory Build

Inventory growing faster than revenue is a signal of poor demand forecasting, SKU proliferation, minimum order commitments or supply chain hedging that has not been optimised. Excess inventory is cash that has already left the business with no return date.

Margin Leakage

Gross margin compression from pricing concessions, product mix deterioration, or cost-of-goods increases not passed through to customers reduces the cash generated per revenue dollar before any working capital consideration.

Capex Intensity

Maintenance and replacement capex requirements that absorb a high proportion of EBITDA structurally reduce free cash flow. The relationship between EBITDA and sustaining capex is a fundamental driver of business quality in asset-intensive models.

SKU Complexity

A large and growing SKU count with significant slow-moving and obsolete stock creates both inventory carry cost and provision requirements. SKU rationalisation is one of the highest-return working capital improvement levers in distribution businesses.

Payment Terms Tightening

Supplier payment terms being shortened — whether through supplier credit policy, early payment discounts or reduced trading limit flexibility — directly reduces DPO and increases the working capital cycle.

Revenue Mix Shifts

Growing the revenue mix toward longer payment cycle customers, project-based revenue or contract structures with staged milestone billing increases the average collection period even if individual DSO terms remain unchanged.

Procurement Discipline

Purchasing decisions made on an ad hoc basis, without consolidated vendor management or forward-planning aligned to demand, create both inventory risk and cost inefficiency that directly impacts cash generation.

Forecasting Gaps

Poor demand forecasting creates both over-stocking (inventory build) and reactive purchasing (premium costs). The businesses with the strongest cash conversion are consistently those with the best demand visibility and the most disciplined procurement cycle.

"The gap between EBITDA and cash is not a financial abstraction. It is a direct measure of how well the operating model is actually run — and it is one of the first things any sophisticated buyer will interrogate."

— Scott Foster, Shape Executive

Transaction Impact

How cash conversion affects enterprise value

Enterprise value in any transaction is determined not just by the multiple applied to EBITDA but by the quality of that EBITDA — and cash conversion is a primary quality signal.

A business generating $3M EBITDA with 90% cash conversion is fundamentally different from one generating $3M EBITDA with 50% cash conversion. The second business requires ongoing working capital funding that either the seller provides or the buyer prices into the acquisition.

Working capital normalisation in a transaction — the process of establishing a reference working capital and agreeing to any closing adjustment — is one of the most technically complex and frequently contested elements of any deal. The businesses that navigate this most effectively are those that understand their own working capital cycle well before any process begins.

Establish a cash conversion baseline

Calculate your business's trailing cash conversion rate — operating cash flow as a percentage of EBITDA — on a monthly basis. Understand the trend and identify the structural drivers. This is the foundation for any working capital improvement programme.

Target DSO first

DSO improvement generates the fastest measurable improvement in cash conversion. A disciplined collections programme, credit limit management and payment terms review can materially improve cash position within a single operating year.

Rationalise inventory

SKU rationalisation, minimum order quantity review, consignment arrangements with key suppliers and improved demand forecasting each reduce inventory carry cost. Inventory reduction generates a one-time cash benefit in addition to the structural improvement in working capital cycle.

Revenue Quality vs Revenue Growth

Cash conversion is a function of revenue quality as well as working capital management. Understanding the revenue dimensions that drive cash generation is essential context for any improvement programme.

The working capital improvement levers are covered operationally in Profit and Working Capital. For the transaction context, Transaction Readiness Assessment assesses cash conversion as one of its 13 categories. The The commercial engine that builds EBITDA covers the operational system — pricing, working capital and pipeline — that most directly improves cash conversion.
