General ledger
The central accounting record that holds every financial transaction in an organisation, organised by chart of accounts.
The general ledger (GL) is the central accounting record of an organisation, holding every posted financial transaction grouped by account in the chart of accounts. Every other module in an ERP — sales, purchasing, inventory, fixed assets, payroll, projects — ultimately writes to the GL through posting groups, so the GL is the single source of truth for the financial statements. In Business Central and Dynamics 365 Finance, GL entries are immutable once posted and are paired with dimensions for analysis. Period close, reconciliations, and statutory reporting all run against the GL.
