Working capital optimization as a source of strategic liquidity: a CFO playbook

When borrowing costs are elevated and credit committees are cautious, CFOs who cannot generate internal liquidity are forced into a uncomfortable position: slow down investment, draw on revolving credit at a premium, or go back to the board with a capital ask. The uncomfortable truth is that many companies already hold the cash they need. It is sitting in bloated receivables, excess inventory, and supplier payment terms that were never renegotiated after the last cycle. The opportunity is not theoretical. McKinsey research has consistently found that companies in the top quartile of working capitalworking capitalWorking capital is the difference between a company's current assets and current liabilities, measuring short-term liquidity and the funds available to run daily operations.View full definition → performance generate two to three percentage points more in free cash flowfree cash flowFree Cash Flow is the cash a company generates from operations after funding the capital expenditures needed to maintain and grow its asset base.View full definition → yield than their sector peers, not because they have better products, but because they manage the cash conversion cycle with discipline.

A step-by-step approach to extracting working capital cash

Step 1: build a single, honest baseline

Before any initiative, you need one number everyone agrees on: the cash conversion cycle (CCC), broken down by business unit, customer segment, and product line. Most finance teams can produce a company-wide CCC figure. Far fewer can tell you that the industrial distribution division runs at 74 days while the direct-to-enterprise segment runs at 38. That granularity is where the real opportunity lives.

Pull three years of data. Calculate days sales outstanding (DSO), days inventory outstanding (DIO), and days payable outstanding (DPO) for each unit. Then benchmark against sector peers using a credible independent source. REL Consulting, now part of The Hackett Group, publishes annual working capital surveys by sector that give genuine quartile comparisons. Do not benchmark against your own historical average. That just measures your own drift.

Step 2: prioritize by cash impact per unit of effort

Not every working capital lever is worth the same political cost. Rank opportunities by two dimensions: the cash value of a one-day improvement, and the organizational resistance you will face. For a company with 400 million euros in revenue, one day of DSO improvement is typically worth around 1.1 million euros in cash. One day of DIO improvement in a capital-intensive manufacturing business can be worth considerably more.

Receivables programs tend to produce fast results and face limited internal resistance, because the finance team owns the process end to end. Inventory reduction is slower and requires operations and procurement to move with you. DPO extension is politically charged when supplier relationships are fragile, as Carrefour discovered when aggressive payment term extensions in 2015 generated significant supplier backlash and eventual regulatory scrutiny in France. Sequence accordingly.

Step 3: attack receivables first, and be specific about the mechanism

DSO improvement is not a collections effort. It is a contract and process redesign problem. Start with the largest 20 accounts by outstanding balance. For each, identify the actual friction point: is the invoice arriving late because of an internal approval chain? Is the payment term in the contract genuinely 60 days, or did someone agree to 90 days verbally during a commercial negotiation and it was never corrected? Are disputes sitting unresolved because no one owns the dispute management process end to end?

Dynamic discounting is worth considering for large customers with strong credit ratings. Rather than waiting 90 days for full payment, you offer a 1.5 or 2 percent discount for payment within 10 days. Whether that is economically rational depends on your cost of capital. If your revolving credit facility costs you 5 percent annually and the discount equates to an annualized cost of 7 percent, you are paying to get your own money back faster. Run the arithmetic before launching any early payment program.

Supply chain finance (reverse factoring) is a different instrument. Platforms like Taulia or C2FO allow you to extend payment terms to suppliers while ensuring they can access early payment through a third-party funder, usually at rates close to your own credit rating. This can extend your DPO by 15 to 30 days without damaging supplier relationships. Taulia is a commercial platform and their case study data should be read with that in mind, but the underlying mechanics are independently validated.

Step 4: reduce inventory without creating service failures

The DIO conversation almost always gets derailed by a fear of stockouts. The correct response is not reassurance but segmentationsegmentationDividing a market into distinct groups of customers who share similar needs, characteristics or behaviours, so each group can be served with a tailored approach.View full definition →. Apply ABC-XYZ analysis: categorize SKUs by revenue contribution (A, B, C) and demand variability (X, Y, Z). The AX segment, high-revenue, predictable-demand products, can sustain lower safety stock targets with minimal service risk. The CZ segment, low-revenue, unpredictable-demand products, often warrants elimination rather than optimization. Philips reduced its SKU count by over 40 percent during a global operations overhaul and achieved meaningful inventory reduction without a measurable increase in delivery failures, according to their published annual reports from that period.

Set a target DIO by segment, tie it to a commercial service level agreement with the business unit, and review it quarterly. Otherwise inventory creep returns within 18 months.

Pitfalls that derail working capital programs

The most common failure mode is launching a working capital initiative as a finance project rather than an operational one. Finance can identify the opportunity and track the metrics. The actual work, changing order-to-cash processes, renegotiating supplier terms, eliminating slow-moving SKUs, requires cross-functional authority. CFOs who do not secure visible CEO sponsorship before launch typically see the initiative stall at the business unit level within 60 days.

The second failure mode is measuring inputs rather than cash. Tracking the number of invoices processed, the number of supplier agreements renegotiated, or the number of inventory reviews completed tells you nothing about whether cash has actually moved. The only metric that matters is the change in net working capitalnet working capitalWorking capital is the difference between a company's current assets and current liabilities, measuring short-term liquidity and the funds available to run daily operations.View full definition → on the balance sheet, reconciled to the cash flow statement.

Watch out for window dressing at period-end. Factoring large receivable balances before the reporting date improves the balance sheet but does not improve the underlying process. It also adds cost and, if the program is off-balance-sheet, carries disclosure risk under IFRS 7.

Quick wins to start this week

• Pull the CCC by business unit for the last 12 months. If your ERP cannot produce this in 48 hours, that is itself a diagnostic.
• Identify the 10 accounts with the largest overdue receivable balance and schedule a call with the commercial owner for each, not the collections team.
• Run a DPO gap analysis: compare your current payment terms against your top 30 suppliers' standard terms and flag every case where you are paying faster than required.
• Ask treasury whether any excess cash on deposit is currently earning below the overnight rate, which would mean your idle liquidity is also sub-optimized.
