A Trial Balance is an accounting report which lists account balances for all your Accounts (“Ledger” and “Group”) for any given reporting period. A company prepares a trial balance periodically, usually at the end of every reporting period. The general purpose of producing a trial balance is to ensure the entries in a company's bookkeeping system are mathematically correct. The totals of Debit and Credit columns must be same for any given period, to ensure the entries are correct.
