How is a chart of accounts structured?
The structure of a chart of accounts is made up of three levels: item, account and subaccount.
1. Category
To begin with, the item is an accounting section that allows grouping different accounts. The item identifies the names received by all the divisions of the operations that make up the financial structure of the company that orders its accounting movements. It could be structured in assets, liabilities and collections.
2. Accounts
Next, the accounts are structured. The account includes all the divisions that make up each item. Every accounting account is used to record the accounting movements that have been made and that have an impact on the company. For example, the asset could be classified in cash, banks, suppliers, customers, among some that can be mentioned.
3. Subaccount
Finally, we find the subaccounts. The subaccount is the accounting term linked to the detailed breakdown of all accounts. This generates the final record of the chart of accounts. The subaccounts are used to detail and control the accounting operations that the company does. For example, the petty cash subaccount is used in the cash account or the banking entities subaccount in the bank account.
