Trail balance

The Trial Balance is a statement of ledger account balances as on a particular instance.

The trial balance is prepared to check/ensure the arithmetical accuracy of accounting. Though not a conclusive proof, the agreement of the trial balance is a prima facie evidence of the absence of mathematical errors. Preparation of Trial Balance is not an act that forms a part of the activities involved in the regular accounting cycle. Since Final Accounting can be completed without the preparation of the Trial Balance, we can say that enabling the preparation of final accounts is not the purpose of the trial balance

Trial Balance is raw data, it is just the balances of all GLs at a particular date / for a particular period. This data can further be used to prepare financials, etc. Today trial balance is not something that gets prepared, but gets "Generated". You dont have to do total of all entries in Ledgers and total them to get the Trial Balance. The question of mathematical accuacy is now out of picture. The Main use for TB now is to plot it as source data for Financials, or other statements (eg. Working Capital, Cash Flow, etc).
