E-commerce Working Capital
financeThe difference between a company's current assets (cash, receivables, inventory) and current liabilities (payables, short-term debt). It measures the ability to fund day-to-day operations.
Definition
Working capital is the operational fuel of a business. It represents the liquid resources available to cover short-term obligations and keep the business running day to day. Positive working capital means current assets exceed current liabilities, providing a cushion for operations. Negative working capital means the business relies on future revenue to pay current bills, a precarious position.
The working capital ratio (current assets / current liabilities) is a common liquidity test. A ratio above 1.5 is generally considered healthy. Below 1.0 signals potential liquidity problems. However, the optimal ratio varies by industry. Retail businesses with fast inventory turnover can operate with lower working capital ratios than manufacturers with slow production cycles.
Managing working capital effectively requires balancing three levers: accounts receivable (collect faster), inventory (stock less but avoid stockouts), and accounts payable (pay on time but not early unless discounts warrant it). Many growing businesses face a working capital crisis: revenue growth requires investment in inventory and staff before customer payments arrive, creating a temporary gap that can starve the business of cash.
Formula
Working Capital = Current Assets - Current Liabilities Example
A business has current assets of $350,000 (cash: $80,000, receivables: $150,000, inventory: $120,000) and current liabilities of $200,000 (payables: $110,000, short-term debt: $60,000, accrued expenses: $30,000). Working capital = $350,000 - $200,000 = $150,000.
