Working capital is where growth eats cash, even when the income statement looks healthy

The Finance Storyteller · Working Capital Explained

The idea

Receivables are sales not yet paid for; inventory is cash sitting on a shelf; payables are purchases not yet paid. Grow the business and the first two grow with it, which means cash goes out before it comes back. The Finance Storyteller defines working capital and then reads it off two real companies, which is the useful part: the same accounting line means something different for a manufacturer with months of inventory and a software company whose customers pay in advance. Knowing which kind of business you are looking at tells you whether growth will consume cash or produce it.

Growth ties up cash in receivables and inventory, so model the working capital a business needs before trusting its profit.

When it works

Three-statement questions, cash flow forecasting, and any growth company whose profit and cash are diverging.

When it may fail

Working capital can be managed, stretched and flattered at a period end, so a single balance sheet date can mislead. Use several and watch the trend.

How to use it

For a company, compute days of receivables, inventory and payables, and the cash the next year's growth will absorb at those levels. Shoe Dog is the same calculation told as a near-death experience.
