Executive Summary

Working capital is the fuel that keeps a company's operating engine running. Managed well, it lowers funding costs, stabilizes supply chains, and releases cash for strategic bets. Managed poorly, it hides operational waste, amplifies shocks, and forces difficult trade-offs between growth and liquidity.

What You'll Learn

  • Clear definitions for DSO, DPO, DIO, and Cash Conversion Cycle
  • Practical diagnostic to identify cash bottlenecks
  • Proven strategies across receivables, inventory, and payables
  • Modern operating model, RACI, and analytics toolkit

Foundations: What We Mean by Working Capital

Working capital is the capital tied up in day-to-day operations, primarily Accounts Receivable (AR), Inventory, and Accounts Payable (AP). Here are the key metrics every leadership team should track:

Days Sales Outstanding (DSO)

Average number of days to collect cash after a sale. Lower is better.

DSO = (Receivables ÷ Annual Sales) × 365

Days Inventory Outstanding (DIO)

Average days inventory sits before being sold. Lower indicates leaner stock.

DIO = (Inventory ÷ COGS) × 365

Days Payables Outstanding (DPO)

Average days you take to pay suppliers. Higher provides more financing.

DPO = (Payables ÷ COGS) × 365

Cash Conversion Cycle (CCC)

End-to-end cash "round trip." Smaller (even negative) is better.

CCC = DSO + DIO − DPO

Why Working Capital Punches Above Its Weight

  • Cash released is cash you don't have to borrow — each day improvement reduces funding needs.
  • It’s a resilience lever — cushions supply shocks and demand swings.
  • It reveals operational truth — bottlenecks expose pricing, forecasting, or process issues.
One-Day Value: Put € on Each Day

Price time in cash to keep debates grounded:

  • AR one-day value = AR ÷ 365
  • Inventory one-day value = Inventory ÷ 365
  • AP one-day value = COGS ÷ 365 (payables funding)
  • CCC cash impact (per day) ≈ (AR + Inventory − AP) ÷ 365

Example: If AR=€30M, Inventory=€20M, AP=€18M → 1 day ≈ €(30+20−18)/365 ≈ €87,671.

The Diagnostic: Where Your Cash is Really Stuck
A high-quality working capital diagnostic quantifies, localizes, and explains cash bottlenecks.
1. Quantify
Establish the cash opportunity

Start with baseline KPIs and pressure-test against:

  • Internal history
  • Peer benchmarks
  • Industry standards
Pro tip: Convert each day into cash using your “one-day value” to keep debates grounded in euros.
2. Localize
Segment before you solve

Company-level KPIs hide variability. Slice by:

  • Customer segments
  • Product/SKU categories
  • Supplier relationships
  • Geographic regions
Reveals cash hotspots: e.g., 5 customers = 40% of past-due AR
3. Explain
Trace operational root causes

Use process reviews to find failure modes:

  • Quote-to-cash issues
  • Plan-to-produce gaps
  • Procure-to-pay delays
Link KPI gaps to clear operational causes before picking solutions.
The Receivables Playbook (DSO)
Improve DSO through better terms, accurate billing, and relationship-building collections.
Terms & Credit Policy
  • Evidence-based terms: align payment terms to behavior and norms.
  • Risk-weighted credit limits: combine payment history + external data.
  • Proactive renewals: refresh limits at renewal or behavior change.
Billing Accuracy & Speed
  • No PO, no invoice: mandatory PO/contract references.
  • E-invoicing by default: reduce errors and cycle time.
  • Straight-through cash app: auto-capture remittance data.
Collections That Build Relationships
  • Segment work: prioritize by risk/value; assign owners.
  • Dunning cadence by risk tier: friendly nudge → reminder → escalation with SLAs.
  • Dispute triage: same-day handling for short-pays and disputes.
  • Fact-based conversations: quantify impact in the customer’s language.
Early-Payment Programs
Use selectively where the implied APR beats your alternative cost of capital; pair with clean billing & e-invoicing.
The Inventory Playbook (DIO/DIS)
Balance availability with agility through better planning, portfolio management, and execution.
Planning & Forecasting
  • Demand design: statistics + sales intelligence.
  • ABC/XYZ segmentation: targets by volatility & value.
  • Shorten frozen windows: smaller buckets, frequent S&OP.
Portfolio & Flow
  • SKU rationalization: eliminate low-velocity variants.
  • Make-to-order: configure slow-movers/custom items.
  • Lead-time compression: reset timing and lot sizes.
Execution Hygiene
  • Real-time accuracy: cycle counts & location discipline.
  • Aging governance: R/Y/G dashboards with burn-down plans.
  • Explicit decisions: anchor to service economics.
The Payables Playbook (DPO)
Optimize terms and execution while maintaining strong supplier relationships.
Terms & Financing Options
  • Benchmark by category: differentiate strategic vs. commodity terms.
  • Supply-chain finance (SCF): extend terms with supplier discounting optionality.
  • Dynamic discounting: pay early for discounts when cash-rich.
Procure-to-Pay Execution
  • PO discipline: early, accurate POs for 3-way match.
  • Automated approvals: risk-tiered routing to avoid delays.
  • Supplier portals: self-service invoices & disputes.

EU Late Payment Directive Note

As of today: the EU Late Payment rules set ~30 days as standard; longer may be possible if expressly agreed and not “grossly unfair.” Check current rules and sector specifics with counsel before extending DPO materially.

Supplier Health Guardrails

  • Track on-time/in-full, defect rate, and lead-time drift.
  • Use SCF/dynamic discounting to avoid starving critical suppliers.
  • Flag term outliers for periodic review.

Collections SLAs (DSO)

  • Risk-tiered dunning cadence with tone & timing playbook.
  • Dispute SLA: acknowledge same day; resolve in 5 business days.
  • Escalation RACI: Sales Ops → Finance Lead → Exec Sponsor.
Operating Model: Sustaining Working Capital Excellence
Governance & Roles
  • Cash council: bi-weekly cross-functional forum (CFO-led).
  • Owner per lever: exec sponsors for AR, Inventory, AP.
  • Policy with escalation: written, tracked, enforced.
Analytics & Transparency
  • Driver-based dashboards: dispute aging, forecast error, exceptions.
  • Cohort analysis: track behavior changes over time.
  • Benchmarking: external references to calibrate ambition.
Incentives & Ways of Working
  • Cash KPIs in performance: DSO, DIO, DPO in scorecards.
  • “Cash war room” sprints: daily standups, heat maps, targets.
  • Continuous improvement: automate insight-to-action loops.

Frequently Asked Questions
Common questions from boards and executive teams.

Should we target negative CCC?

It depends. Retailers often run negative CCC as they collect at sale while paying suppliers later. Capital-goods makers may not. Anchor on peer benchmarks and risk appetite.

We’re in the EU. Can we push DPO beyond 30 days?

The EU Late Payment rules set ~30 days as standard, allowing longer only when expressly agreed and not “grossly unfair.” Legal and reputational risks rise with excessive extensions.

Are early-payment discounts worth it?

Often yes, if the implied annualized return beats your alternative use of cash and you target the right customers. Pair with e-invoicing and clean billing.

How do we avoid starving suppliers?

Use SCF and dynamic discounting to give suppliers optional liquidity at your spread. Monitor supplier health, lead times, and quality—aim for mutual resilience.

Closing Thought

Working capital management is not a finance side-project; it is a company-wide operating system for resilience and growth. When leadership treats cash as everyone's job, when Sales closes clean orders, Operations plans to real demand, Procurement sets fair terms with clean execution, and Finance provides simple rules and great data, cash accelerates, cost falls, and risk declines. That is the compounding power of disciplined working capital.
