Working Capital
Working capital is the money a business needs to fund day-to-day operations. It rarely appears in headlines but it explains many cash flow surprises.
Why this matters for beginners
Growth consumes working capital. A profitable company can run short of cash simply because it is growing quickly and funding inventory and receivables.
Main explanation
Working capital is broadly inventory plus receivables minus payables. Inventory and receivables consume cash; payables temporarily provide it.
When a company grows, it usually buys inventory and waits for customers to pay before receiving cash. That gap must be funded from somewhere.
Some business models have negative working capital, collecting from customers before paying suppliers. These models are funded partly by their own operations.
Watch for inventory or receivables growing faster than revenue. That usually means unsold stock or customers taking longer to pay.
Example using a real company
A retailer that pays suppliers in sixty days but sells stock in thirty collects cash before the supplier invoice falls due, funding growth without borrowing.
- →Receivables rising 30 percent while revenue rises 10 percent: collection is slowing.
- →Negative working capital: customer payments arrive before supplier payments are due.
Common beginner mistakes
- ✕Assuming profit and cash move together during rapid growth.
- ✕Ignoring inventory growing faster than sales.
- ✕Treating negative working capital as an accounting error.
