Accounting software turns source transactions into a controlled ledger and reporting process. It does more than store income and expense totals. The system applies a chart of accounts, balanced journal logic, subledgers, dimensions, periods, permissions, and reconciliation workflows so each recorded event can be traced from evidence to its financial-statement effect.
This explainer follows that chain from configuration and source documents through posting, reconciliation, adjusting entries, close, and reporting. It explains how automation supports consistent treatment without making judgment disappear. Accurate output still depends on correct policies, complete records, governed mappings, independent review, and transparent correction when the books do not agree with external evidence.
