Plain definition
Negative working capital occurs when current liabilities exceed current assets. In an operating analysis, negative net operating working capital means supplier credit, customer advances, and operating accruals exceed receivables, inventory, and other operating current assets. It can release cash as the business grows, but it is not automatically evidence of financial strength.
Illustrative example
Monetary examples use Saudi riyals (SAR). The same principles apply in other currencies.
An online retailer holds inventory, receivables, and prepaid operating costs. It owes suppliers and has accrued operating costs, producing negative operating working capital of . Customers pay at checkout, while the supplier terms are 45 days, so the model receives cash before much of the inventory cost is paid.
The operations manager proposes buying more stock because the negative balance looks favourable. Finance first tests whether sales will continue to be paid upfront and whether the supplier will retain the 45-day terms. If either assumption fails, the apparent cash benefit can disappear just as inventory purchases rise.

Why it matters
The same negative number can describe a durable cash-generating model or unpaid obligations that are becoming overdue. Looking only at the sign of the measure can cause management to over-expand or delay action on a genuine liquidity issue.
Practical consequence
Break the balance into customer advances, trade payables, accrued expenses, tax, debt, and other current liabilities; they do not carry the same risk. Age the supplier and tax balances, confirm customer prepayments and refund obligations, and compare each due date with the cash forecast. Monitor whether the negative position comes from normal terms or from payments that have slipped beyond agreed dates.
