A trial balance has some limitations :
- It does not prove that all transactions have been recorded
- It does not prove that the ledger is correct
- Numerous errors may exist even though the trial balance columns agree
- It cannot find the missing entry from the journal
- It cannot find the missing entry from the ledger
- It cannot protect the repeated postings
- It cannot protect the offsetting errors
- It cannot protect the errors of principles
- It cannot protect the errors of commission
- It cannot protect the errors of omission
In short, a trial balance does not guarantee freedom from recording errors.
