What is the reason that prepare trial balance?

any difference between the credits and debits that shows up in a trial balance is nothing more than a posting error that took place some time during the time period under consideration. When that is the case, the error can usually be spotted with ease and a state of equality restored between the debits and credits.

A trial balance is especially effective in helping to identify a double entry posting error. Often, the difference between the credits and debits will quickly lead to a specific posting that may have been erroneously entered in two different columns or accounts within the overall set of books.

At the same time, the trial balance may indicate an inequality that was created by entering a credit or debit into the wrong account. When this is the case, finding the error may be a little more time consuming, as it will involve reviewing each posting for the period cited and confirming the posting took place in the right account and under the correct classification.

Running the trial balance is usually a precursor to the preparation of other financial documents, such as and Income and Expense Statement. By making sure that all debits and credits posted during the period are correct, preparing reports and other documents based on the accounting data is easier to accomplish.
