Accounting Information Systems (QNO1 / PQNO) Practice Exam

In essence, the trial balance checks that the accounting system’s double-entry records balance: the total of all debit balances equals the total of all credit balances for all general ledger accounts at a given point in time. This helps catch arithmetic and posting mistakes, such as added incorrectly, skipped postings, or misposted entries, because the double-entry system requires every transaction to affect at least one debit and one credit equally. It isn’t used to calculate taxes, adjust inventory levels, or forecast future expenditures; those tasks come after you’ve confirmed the balances and then apply the necessary adjustments. The trial balance also serves as a starting point for preparing financial statements and for recording adjusting entries, but remember that a balanced trial balance doesn’t guarantee there are no other kinds of errors—omissions or misclassifications can still exist and require further investigation.
