IGCSE Accounting: Verification of Accounting Records — Revision Notes

Condensed for the final weeks. For the full explanation, use the Verification of Accounting Records study guide.

The core question this topic answers

Four different techniques, one underlying purpose: how do we know the records are right? Revise them side by side, not in isolation — each catches a different kind of problem.

3.1 The trial balance

Lists every ledger balance in debit and credit columns. If they agree, double entry has been applied consistently — but this is necessary, not sufficient proof of accuracy: several error types leave the totals balanced despite being wrong.

3.2 The six error types — the one to know cold

Error	What happened
Omission	Transaction left out entirely
Commission	Correct account type, wrong specific account
Principle	Wrong account type altogether
Original entry	Wrong amount, entered consistently both sides
Complete reversal	Debit and credit swapped
Compensating	Two unrelated errors cancel out

None of these six disturb the trial balance total. Only errors that cause an actual imbalance require a temporary suspense account, corrected once the cause is found via journal entries.

Classify the error type before attempting the correcting entry — guessing the journal entry first is the most common way to lose marks here.

3.3 Bank reconciliation

The cash book balance and the bank statement balance often differ due to timing, not error:

• Unpresented cheques — recorded in the cash book, not yet cleared by the bank.
• Outstanding lodgements — deposits recorded in the cash book, not yet credited by the bank.
• Bank charges/standing orders the business hasn’t recorded yet.

A bank reconciliation statement explains the difference; it does not correct an error, because there usually isn’t one.

3.4 Control accounts

A sales ledger control account and a purchases ledger control account summarise many individual personal-ledger balances in one place — built from totals in the books of prime entry, not by adding up each individual balance. This gives an independent check that localises errors faster than checking every account by hand.

Building revision around “what does each technique catch”

Rather than four separate revision lists, build one table linking technique to what it can and cannot detect: the trial balance catches arithmetic imbalance only; error correction handles the specific error types a trial balance misses; bank reconciliation checks cash records against an independent external source (the bank); control accounts check personal ledgers against general-ledger totals. This framing answers the exam’s favourite question format — “explain why [technique] would/would not detect [described error]” — far more reliably than memorising each technique’s mechanics in isolation.

Worked example: classifying an error

$450 paid for vehicle repairs is posted to Motor Vehicles (asset) instead of Vehicle Repairs (expense). Both entries were made correctly for $450, so the trial balance still balances.

Type:       Error of principle
            (wrong account TYPE — asset instead of expense —
            not merely the wrong specific account)
Correction: Debit Vehicle Repairs $450
            Credit Motor Vehicles $450
Suspense?:  Not needed — the trial balance total is unaffected

Suspense account: when it’s needed, and when it isn’t

A suspense account is a temporary holding account opened only when the trial balance actually fails to balance — it records the difference between the two column totals until the cause is found. Once identified, the correcting journal entry clears the suspense account balance to zero. Because the six named error types (3.2) never cause an imbalance in the first place, none of them require a suspense account on their own — a frequent exam mistake is opening one anyway “to be safe” when the trial balance was never actually out of balance.

Exam traps

• Assuming a balancing trial balance proves the accounts are error-free.
• Confusing commission (wrong specific account, correct type) with principle (wrong account type entirely).
• Treating unpresented cheques/outstanding lodgements as errors needing correction in the cash book, rather than timing differences.
• Forgetting a control account is built from source-document totals, not from summing individual personal-ledger balances.
• Opening a suspense account for an error that doesn’t actually cause an imbalance (any of the six named error types).

Self-test

1. Why does a balancing trial balance not guarantee the accounts are correct?
2. Name the six error types that do not disturb the trial balance total.
3. What is the difference between an error of commission and an error of principle?
4. What are unpresented cheques and outstanding lodgements, and how does a bank reconciliation statement treat them?
5. What is a control account built from, and what does it check?

Answers: 1. Because several error types (omission, commission, principle, original entry, complete reversal, compensating) leave the debit and credit totals equal despite the records being factually wrong. 2. Omission, commission, principle, original entry, complete reversal, compensating errors. 3. Commission posts to the correct account type but the wrong specific account; principle posts to the wrong account type entirely. 4. Timing differences between the cash book and the bank statement — cheques recorded but not yet cleared, and deposits recorded but not yet credited; the reconciliation statement explains these differences rather than correcting them as errors. 5. Built from totals in the books of prime entry; it checks the accuracy of the (more detailed) sales or purchases ledger by providing an independent summary total to compare against.
