A T-account operates in a way that paints the transactions of an account in a T shape. The left side of the account reflects all debits, in turn; the right side reflects all credits. For example, when a business organization receives cash from sales, the account called Cash is debited while Sales account is credited. In most cases, after the client had transacted at different accounts for some time, the debits and credits made at each account are added then balanced. If there are more debits than credits it means you have a debit balance, and if the opposite, you have a credit balance. This method allows the recognition of transactions in the correct manner.
