Accounting is the discipline of recording, classifying, summarizing, and interpreting financial transactions. It answers two questions: what does an entity own and owe, and how did those positions change over a given period? The discipline provides the systematic evidence base for economic decision-making — without it, an organization can’t distinguish profit from loss or solvency from insolvency.
The foundation of modern accounting is double-entry bookkeeping, a method developed in medieval Italy and first codified by Luca Pacioli in 1494 [citation needed]. Double-entry bookkeeping requires that every transaction be recorded as equal debits and credits across at least two accounts, producing a self-balancing system that makes errors detectable and fraud more difficult to conceal.
Methods
Accounting produces knowledge through standardized recording and classification. Practitioners maintain journals (chronological records of transactions) and ledgers (records organized by account). They verify internal consistency through the trial balance — a check that total debits equal total credits across all accounts. They produce financial statements (balance sheets, income statements, cash flow statements) that summarize an entity’s position and performance.
The discipline divides into branches by purpose:
- Financial accounting reports an entity’s position and performance to external parties (investors, regulators, creditors) according to standardized frameworks (GAAP, IFRS).
- Management accounting produces internal reports to support operational decisions — budgeting, cost analysis, performance measurement.
- Tax accounting applies tax law to determine obligations and plan for them.
- Auditing independently examines financial records to verify their accuracy and compliance with standards.
- Forensic accounting investigates financial records for evidence of fraud, embezzlement, or other irregularities.
