🗂️Chart of Accounts

NEW

Also known as: COA

A governed, hierarchical list of all general ledger accounts used to classify and report financial transactions.

DESCRIPTION

The chart of accounts is the enterprise blueprint for financial classification, defining codes and groupings for every general ledger account. It enables consistent posting, rollups, and standardized reporting. Good COA design balances stability with enough granularity for management insight. It often includes account segments (e.g., company, natural account) and integrates with dimensions like cost center and project. Changes are controlled by governance to preserve comparability and compliance. The COA underpins consolidations, statutory reporting, and analytics across business units.
