Plain definition
Liabilities are present obligations of a business arising from past events, the settlement of which is expected to require an outflow of resources. They include supplier payables, loans, accrued wages, tax obligations, and deferred income. A liability is not limited to an invoice already received: goods or services received, a financing agreement, or advance cash from a customer can create an obligation before a payment date arrives.
Illustrative example
Monetary examples use Saudi riyals (SAR). The same principles apply in other currencies.
A company receives raw materials worth on 29 June and agrees to pay in 30 days. At June close it records inventory or production cost and a payable where appropriate, even though the supplier invoice arrives on 4 July. The payable tells management that cash or another resource will be needed to settle a past obligation; the July payment clears it.
The example is hypothetical. An obligation can involve judgment about contract terms, uncertainty, or classification, and not every possible future payment is a present liability.
Why it matters
Understated liabilities make profit, liquidity, and solvency look better than they are. A founder may commit available cash to growth, dividends, or new hires without seeing obligations already created by purchases, payroll, taxes, or customer advances.
Practical consequence
Maintain a liability schedule that includes counterparty, origin, amount, due date, evidence, current or non-current classification where required, and owner. Reconcile payables to supplier statements, review accrued and deferred balances, and use a dated cash forecast to test settlement capacity. Investigate old debit supplier balances and unexplained liabilities rather than netting them away.
