Profit cannot pay bills before customers pay
Unpaid invoices, inventory, and debt can drain cash while the income statement still looks healthy.
A profitable business can run out of cash when payments fall due before customers pay, or when stock, equipment, and debt consume available funds. Watch collection delays, rising inventory, and shrinking credit headroom before a missed payroll makes the shortage obvious.
Profit and cash measure different things: accrual accounts record revenue when earned and recognize expenses even when money changes hands later, as the SEC's financial-statement guide explains. Consider a hypothetical company that delivers $100,000 of goods, recognizes $80,000 of costs, pays those costs now, and collects in 60 days. It reports $20,000 of profit before tax while losing $80,000 of cash in the meantime; starting with $50,000 leaves a calculated $30,000 funding gap unless financing or other receipts cover it.
Growth can widen that gap because extra orders need stock and labor before they generate collections. BDC's working-capital guidance describes how growing receivables and inventory absorb funds that cannot simultaneously pay other bills. The room for delay can be small: a JPMorgan Chase Institute study using 2015 transactions from 597,000 small businesses found a median buffer of just 27 days of typical cash outflows, a historical customer sample rather than a current universal benchmark.
Equipment and loan repayments create another gap between accounting profit and the bank balance. Equipment uses cash when paid for, while depreciation generally spreads its expense over years; repaying loan principal consumes cash without becoming an expense like interest. In a hypothetical example, $100,000 of operating cash followed by $90,000 of equipment purchases and $40,000 of principal payments leaves cash $30,000 lower before any other movements.
A payment calendar reveals trouble that an annual profit forecast can miss: BDC recommends a rolling 13-week cash forecast, updated weekly. Enter receipts when customers are realistically likely to pay and bills on their due dates, while showing borrowing separately with its actual limits. Then delay a major receipt to see whether the lowest projected balance becomes negative and identify the amount and week that need attention.
Use that shortfall date to arrange faster collection, deposits, rescheduled spending, or financing while there is still time to act.
