The chart of accounts (COA) shows the ledger accounts that store your financial data. Business Central includes a standard COA that is ready to support your business. You can, however, change the default accounts, and you can add new accounts.
The chart of accounts numbering system assigns a unique code or number to each account, enabling easy identification and classification. The numbering system provides a clear structure, with the first digit indicating the major account category and subsequent digits providing further subcategories.
