Why working capital matters to a first-time founder
A profitable company can still fail if cash is tied up in stock or unpaid invoices while bills fall due. Monitoring short-term assets and obligations helps a founder plan purchasing, collections and payment terms. The number also highlights whether growth is consuming cash faster than operations can replace it.
Examples of working capital
A retailer has $35,000 cash, $40,000 receivables and $25,000 inventory, giving $100,000 of current assets. It owes suppliers $45,000 and has $15,000 of other current liabilities. Working capital is $40,000, but the founder separately checks when receivables and stock can actually turn into cash.
Common misunderstanding
Positive working capital does not guarantee that bills can be paid today. Inventory may sell slowly and customers may pay late, while liabilities can be due immediately. Negative working capital is not automatically disastrous either; some businesses collect from customers before paying suppliers. Timing and business model matter.
When to use it
Review it monthly and before rapid growth, a large stock order or new payment terms. Pair the total with a short-term cash forecast, receivables ageing, inventory movement and due dates. If a gap appears, fix collections or terms before assuming additional borrowing is the best answer.
