Working Capital & Liquidity Guide: Acid-Test, Current Ratio & Cash Conversion Cycle

1. What Is Working Capital & Why Does Cash Timing Matter? More businesses fail from running out of cash during periods of rapid growth than fail from lack of revenue.

Working capital measures whether your short-term liquid inflows will arrive in time to satisfy immediate payables, payroll, rent, and loan service.

2. Quick Ratio (Acid-Test) vs. Current Ratio

The critical distinction is the exclusion of merchandise inventory and prepaid expenses. In an emergency credit contraction: - Receivables can be factored or collected. - Marketable securities can be sold in seconds. - Inventory cannot be liquidated overnight without taking severe 50%-70% discounts that destroy profitability.

A Quick Ratio of $\ge 1.0$ indicates that for every $1.00 of upcoming bills, the business holds $1.00 in immediately available liquidity.

3. The Cash Conversion Cycle (CCC) Engine To master working capital, finance leaders track the **Cash Conversion Cycle (CCC)**:

Where: - DIO (Days Inventory Outstanding): How long cash sits on warehouse shelves before selling. - DSO (Days Sales Outstanding): How long customers take to pay invoices. - DPO (Days Payable Outstanding): How long you take to pay suppliers.

Shortening DIO and DSO while responsibly extending DPO pulls cash into your business without taking on expensive bank debt!
