Treasury Practice Guide

Optimizing Working Capital and Operating Cash Flow

Net Working Capital (NWC) and the Cash Conversion Cycle (CCC) govern the internal liquidity generation and debt capacity of any corporation.

1. The Three Drivers of Capital Lockup

  • Days Sales Outstanding (DSO): Collection speed of customer invoices. Enforced payment terms, early settlement discounts, and disciplined dunning cycles accelerate cash inflows.
  • Days Inventory Outstanding (DIO): Velocity of inventory turnover. Trimming obsolete lines, just-in-time delivery arrangements, and lean buffering release cash from warehouses.
  • Days Payables Outstanding (DPO): Utilization of supplier credit. Extended terms act as interest-free liquidity, provided early settlement discounts are systematically evaluated.

2. Cash Flow Leverage

Each day carved out of the Cash Conversion Cycle translates into a permanent cash inflow to bank accounts, while continuously eliminating borrowing expenses on working capital credit facilities.

Frequently Asked Questions

Key Practical Questions on Working Capital

How is the Cash Conversion Cycle computed?
CCC equals Inventory Days plus Receivables Days minus Payables Days: CCC = DIO + DSO − DPO.
What is a healthy DSO benchmark?
In European B2B environments, healthy DSO levels range between 30 and 45 days. Numbers exceeding 60 days signal customer insolvency risks or process bottlenecks in billing.
How much cash is released by a 1-day DSO improvement?
For a business with €50M in revenue, every single DSO day trimmed releases exactly (€50,000,000 / 365) = approx. €137,000 directly into the bank account.
Can the CCC be negative?
Yes. Businesses with negative CCC collect payments from customers long before paying suppliers (e.g. retailers, subscription models), generating interest-free operational float.
