New benchmarking data reveals a 23% free cash flow gap between top-quartile and average companies, and the culprit is almost always working capital management that gets treated as operational housekeeping rather than strategic finance.
Key Takeaways
Ask a CFO for their top strategic priorities in 2026 and the answers cluster predictably around AI investment, M&A pipeline, and macroeconomic scenario planning. Working capital optimisation rarely makes the list, and that gap between stated priority and actual financial impact is costing companies billions in unnecessarily trapped cash. A landmark benchmarking study from the Institute for Corporate Finance Excellence, covering 1,200 companies across nine industries, puts a precise number on the opportunity: top-quartile working capital performance is associated with 23% higher free cash flow generation versus the industry median, even after controlling for revenue growth and margin differences.
"This is the most consistently undervalued lever in corporate finance," said Brendan Ross, managing partner at Westfield Capital Advisory and one of the study's co-authors. "Every CFO knows working capital matters in theory. But in practice, it gets delegated below the finance leadership level, managed as an operational metric, and never receives the rigorous cross-functional attention it deserves. The data shows exactly what that inattention costs."
The benchmarking framework decomposes working capital performance into three classical levers: days sales outstanding (DSO), days payable outstanding (DPO), and days inventory outstanding (DIO). Looking across the full dataset, DSO is the single largest driver of the gap between top-quartile and average performers: best-in-class companies collect from customers 11 days faster on average, a difference that at a $1 billion revenue company represents roughly $30 million in permanently released cash. DIO is the second-largest driver, with top performers running 18% leaner inventory relative to revenue, enabled by better demand forecasting and supplier lead-time management. DPO differences are present but smaller in magnitude, partly because many companies have already optimised their payment terms over the past decade of supply chain finance expansion.
The study also identifies an important interaction effect: companies that optimise all three levers simultaneously generate disproportionate free cash flow improvement, because the working capital cycle is a system rather than three independent levers. Collecting faster, paying slower, and holding less inventory create a compounding cash flow benefit that exceeds the sum of the individual improvements.
Among the specific tools drawing attention in the current environment, dynamic discounting is experiencing a significant resurgence of interest. The concept is straightforward: a company with surplus cash offers suppliers the option to receive early payment in exchange for a discount, effectively deploying idle balance sheet cash at an annualised yield of 60–90 basis points above money market rates, while simultaneously supporting supplier liquidity. In an environment where cash yields have normalised but are likely to compress as rates continue their gradual decline, that incremental return is increasingly attractive to treasury functions looking to optimise their cash management strategy.
"Working capital is the last major source of organic cash flow improvement that most companies haven't fully mined. The ones getting serious about it are finding that the returns dwarf almost anything else they can do without taking on incremental risk." , Brendan Ross, Westfield Capital Advisory
Perhaps the most striking finding in the ICFE research is the priority gap. When CFOs were asked to rank their top five strategic priorities for 2026, only 34% included working capital optimisation in that list, yet when the same CFOs were shown the benchmarking data on free cash flow impact, 87% said working capital deserved to be a top-three priority. The disconnect between stated and revealed preference reveals an organisational tendency to treat working capital as operational plumbing rather than strategic finance.
The companies closing that gap share a common characteristic: they have elevated working capital accountability to CFO-level attention, built explicit KPIs into business unit incentive structures, and created dedicated cross-functional teams with P&L authority to implement changes that span procurement, sales, operations, and finance. The working capital improvement journey is, at its core, a change management challenge as much as a financial engineering one, and that is precisely why delegating it below the CFO level reliably produces sub-optimal results.
