In the previous chapter we have learnt that a Trial Balance is prepared to check the arithmetic
accuracy of transactions recorded in a Journal posting them into the ledger and balancing the ledger
account. If a Trial Balance agrees it is assumed that recording posting etc. have been done correctly.

Accuracy is assured only when there are no errors in the books of accounts. To confirm accuracy
errors are identified and rectified. Many business units have shifted from manual accounting to
computerized accounting. Yet errors in accounting are unavoidable. Hence errors are to be located
and rectified to find out the real profit or loss and financial position.
