Compensating errors

These do not disturb the equality of debits and credits.


2. Errors that DO affect the Trial Balance

Transposition error
Error of original entry
Placing amounts on the wrong side
Only one side of a transaction recorded

These create imbalances, leading to a difference in the trial balance.

Once errors are found and corrected, the suspense account must be closed.
