A Chart of Accounts (COA) is a systematic listing of all the accounts used by an organization to record financial transactions. It serves as a framework for organizing financial data, making it easier to track income, expenses, assets, and liabilities. Each account is assigned a unique identifier, which helps in categorizing and reporting financial information accurately. The COA is typically divided into several categories, such as assets, liabilities, equity, revenues, and expenses. This structure allows businesses to maintain clear and organized financial records, facilitating better decision-making and compliance with accounting standards.
