What is a balance sheet?
Short answer: A balance sheet is the financial statement of a company's assets, liabilities and equity at one reporting date. It shows financial position at that date, whereas an income statement and a cash flow statement explain activity over a period.
The organising relationship is:
Assets = Liabilities + Equity
An asset is an economic resource controlled by the company. Common examples include cash, trade receivables, inventory, equipment and certain intangible assets. A liability is a present obligation, such as a supplier balance, borrowing, tax payable or obligation to deliver prepaid services. Equity is the residual interest in assets after deducting liabilities. It includes contributed capital, retained results and other reserves required by the applicable reporting framework.
How the statement is built and reviewed
Each balance comes from the general ledger and should be supported by a reconciliation or schedule. Bank reconciliations connect ledger cash to bank records. Receivables and payables listings connect customer and supplier accounts to their control accounts. Fixed-asset registers support cost, depreciation and disposals. Inventory records support quantities, costing and write-downs. The close process also records accruals, provisions, tax balances, financing entries and foreign exchange effects.
Current and non-current classification helps users assess timing, but it is not a substitute for the notes or contractual terms. Restricted cash may not be available for general use. Debt shown as non-current may become current after a covenant breach or refinancing fact pattern, depending on the accounting rules. A balanced equation only proves that debits equal credits. It does not prove that assets exist, liabilities are complete or measurements are reasonable.
Example
At month end, a company records cash of 900, trade receivables of 1,100, inventory of 700 and equipment with a net carrying amount of 1,300. Assets therefore total 4,000. Supplier balances are 650, accrued expenses are 250 and bank debt is 1,100, so liabilities total 2,000. Equity must be 2,000 because 4,000 minus 2,000 equals 2,000. The receivables schedule then identifies 180 overdue by more than 90 days. If finance concludes that 80 is not recoverable, it records an 80 impairment expense and reduces receivables to 1,020. Assets and equity each fall to 3,920 and 1,920 respectively, while liabilities remain 2,000. The revised equation still balances.
Why it matters in reporting, financing and a sale
Management uses the balance sheet to monitor liquidity, working capital, capital expenditure and funding structure. Lenders assess available cash, collateral, leverage and the obligations competing for repayment. In a sale, buyers use detailed balance-sheet schedules to test net debt, normal working capital and liabilities that may require specific purchase agreement treatment. A company can report profit while becoming less liquid if receivables or inventory absorb cash.
Limits and reporting requirements
Reviewers often go wrong by leaving old reconciling items unresolved, netting assets and liabilities without a permitted basis, omitting accruals, treating restricted cash as freely available, or assuming book equity equals market value. The labels balance sheet and statement of financial position are often used for the same primary statement. Exact recognition, measurement, classification and disclosure requirements depend on the applicable accounting framework. IFRS 18 replaces IAS 1 for annual periods beginning on or after 1 January 2027, with earlier application permitted. Local company law, tax rules, loan documents and transaction agreements can require separate analysis.
