The worked question on this page is original educational practice. It is not represented as a question from an official previous-year examination paper.
01 / UNDERSTANDING
Review the question
Create an original question with balanced totals and an omitted invoice. Ask which assertion remains untested; do not design the solution around the false premise that all errors create unequal totals. Pair an agreed trial balance with an invoice dated in the reporting period but absent from the ledger. Ask how both facts can be true and what further work is needed. The solution should identify a complete omission and the role of supporting-document review, not assume a hidden arithmetic imbalance.
02 / UNDERSTANDING
The concept in context
Some mistakes preserve equality. Omitting both sides, posting to the wrong expense account or recording an equal wrong amount on both sides may leave totals balanced. A complete review therefore also needs source-document checks, account scrutiny and appropriate period-end procedures, rather than relying only on the trial balance.
03 / UNDERSTANDING
A worked learning case
A business omits an entire utility invoice and its related liability from the books. The debit and credit totals still agree because neither side was posted. A reviewer finds the missing invoice through a supporting-document check, demonstrating why an agreed trial balance cannot establish completeness on its own.
ORIGINAL EDUCATIONAL PRACTICE
Try it before you check.
Can a trial balance agree when an entire transaction has been omitted?
Show the answer and reasoning
Yes.
If both the debit and credit of a transaction are absent, the existing totals can remain equal. The trial balance tests arithmetic agreement rather than complete recording of economic events. Documentary review and other accounting checks are needed to identify omissions, classification errors and period-related mistakes that preserve equality.
Two traps to watch for.
- Calling an agreed trial balance proof of complete accuracy.
- Searching only for one-sided errors during the accounting review.
YOUR TOPIC-SPECIFIC LEARNING MAP

Compare omission with a one-sided posting error.
Identify a document check that could reveal the missing invoice.
Explain the idea, apply it to a new situation, then check what changed in your reasoning.
