Comparison of Error Types
| Feature | Errors NOT Affecting Trial Balance Agreement | Errors THAT Affect Trial Balance Agreement |
|---|---|---|
| Impact on Trial Balance | The trial balance totals still agree. The error results in equal, albeit incorrect, debits and credits. | The trial balance totals do not agree. The error results in unequal debits and credits. |
| Detection | Cannot be found by preparing a trial balance. Often discovered through reconciliations or incidental checks. | Are revealed by the preparation of a trial balance that does not balance. |
| Use of Suspense Account | Correction does not require a suspense account. A journal entry is made between the two (or more) affected accounts. | A suspense account is required to temporarily balance the books and facilitate correction. |
| Examples | Error of Omission, Error of Commission, Error of Principle, Error of Original Entry, Compensating Errors, Complete Reversal of Entries. | Transposition Error, Casting (addition) Error, Single-sided Entry, Unequal Debit and Credit Posting. |

The Purpose and Principles of Bank Reconciliation
A bank reconciliation statement is a crucial internal control document that explains the difference between the bank balance shown in a business's cash book and the corresponding balance on its bank statement. These differences arise primarily due to timing. For example, the business may have recorded a cheque payment in its cash book, but the recipient has not yet presented it to the bank (an unpresented cheque). Conversely, the bank may have processed a direct debit or added bank charges that the business is not yet aware of. The reconciliation process verifies the accuracy of the cash book entries, identifies unrecorded transactions, and detects potential errors or fraudulent activity, ensuring the cash figure reported in the financial statements is accurate and reliable.
Reconciles the business's cash book balance with the bank statement balance.
Primary causes of differences are timing (unpresented cheques, outstanding lodgements) and items not yet recorded in the cash book (bank charges, direct debits).
Acts as a key internal control to detect errors and prevent fraud.
Ensures the cash balance in the statement of financial position is correct.
Always update the cash book for items appearing on the bank statement but not yet in the cash book (e.g., bank charges, interest, direct debits) before you begin preparing the final reconciliation statement. This is a mandatory first step in the standard examination method.
Control Account Reconciliation
Control accounts, such as the Sales Ledger Control Account (SLCA) and Purchases Ledger Control Account (PLCA), are summary accounts maintained in the general ledger. The SLCA balance should, in theory, equal the total of all individual customer balances in the sales ledger (known as the schedule of trade receivables). A control account reconciliation is the process of comparing these two figures. Any discrepancy signals an error in either the general ledger or the subsidiary ledger. Common errors include incorrect casting in books of prime entry, omissions, or posting to the wrong account. This reconciliation is a vital self-checking mechanism that maintains the accuracy of accounting records and helps to isolate errors efficiently.
The SLCA balance is reconciled with the total of the schedule of trade receivables.
The PLCA balance is reconciled with the total of the schedule of trade payables.
The purpose is to verify the arithmetical accuracy of the sales and purchases ledgers.
Discrepancies must be investigated and corrected via journal entries.
Supplier Statement Reconciliation
This is another key reconciliation procedure where a business compares the balance in its Purchases Ledger for a specific supplier with the statement of account received from that supplier. The supplier's statement shows their record of transactions with the business (invoices, payments, credit notes) and the outstanding balance from their perspective. Discrepancies can arise from goods in transit, payments not yet received by the supplier, unrecorded invoices, or disputes. Reconciling these statements helps ensure that liabilities (trade payables) are accurately recorded and that payments are made correctly and on time.
Compares individual supplier account in purchases ledger with supplier's statement.
Identifies timing differences (e.g., payment in transit).
Helps detect missing invoices or credit notes.
Ensures accuracy of trade payables in the financial statements.
Identifying and Correcting Errors using a Suspense Account
When a trial balance fails to agree, it indicates one or more errors that affect its totals. To proceed with preparing draft financial statements, a suspense account is opened. The difference in the trial balance is entered into this temporary account to make the debit and credit totals equal. The accountant then investigates the cause of the difference. Errors such as transposition (e.g., £54 posted as £45), single-sided entries, or incorrect casting are common culprits. Once an error is identified, a journal entry is created to correct the relevant account(s) and clear the corresponding amount from the suspense account. The ultimate goal is to reduce the suspense account balance to zero, signifying that all identified errors have been rectified.
A suspense account is a temporary account used to balance the trial balance when errors exist.
It is used for errors that cause unequal debit and credit totals.
Errors are corrected using journal entries that involve the suspense account.
A zero balance in the suspense account indicates all identified errors have been corrected.
Verification of Assets and Liabilities
Verification goes beyond reconciling numbers in the books; it involves confirming the actual existence, ownership, and valuation of assets and liabilities. This provides physical or external evidence to support the accounting records. Key verification procedures include:
- Physical Verification of Non-Current Assets: Periodically counting and inspecting tangible assets like machinery, vehicles, and equipment and comparing the results to the non-current asset register. This confirms their existence and condition.
- Inventory (Stock) Count: Physically counting inventory at the end of an accounting period. The results are compared to the inventory records to identify discrepancies due to theft, damage, or recording errors.
- Debtor and Creditor Circularisation: Directly contacting a sample of trade receivables (debtors) and trade payables (creditors) to ask them to confirm the balance they have recorded for the business. This provides independent, external confirmation of the amounts owed and owing.
Reconciliation as a Wider Internal Control Procedure
Beyond the mechanics of balancing accounts, reconciliation is a cornerstone of a strong internal control system. Regular and timely reconciliations (of bank accounts, control accounts, and supplier statements) serve multiple purposes. They act as a deterrent to fraud by increasing the likelihood of detection. They ensure errors are identified and corrected promptly, preventing them from compounding over time. This verification process provides management with assurance that the assets and liabilities of the business are fairly stated. For example, reconciling supplier statements to the PLCA can uncover unrecorded invoices or disputes over payments, safeguarding the business's resources and ensuring liabilities are not understated. Ultimately, it enhances the reliability and integrity of the entire accounting system.
Deters and detects fraudulent activities, such as unauthorised payments.
Ensures prompt detection and correction of accounting errors.
Verifies the existence and valuation of assets (cash, receivables) and liabilities (payables).
Increases management's confidence in the accuracy of financial reports.

Error of principle — wrong category (expense vs asset).
On 31 March, a business's cash book showed a bank balance of $3,450. The bank statement received on the same day showed a balance of $4,075. The following discrepancies were found:
- Cheques issued but not yet presented to the bank totalled
- A direct debit for insurance of $350 appeared on the bank statement but was not in the cash book.
- Bank charges of $45 were shown on the bank statement only.
- A customer paid $600 directly into the bank (credit transfer), but this was not yet recorded in the cash book.
- Lodgements (deposits) made on 31 March of $860 were not yet credited on the bank statement.
Prepare the updated cash book and a bank reconciliation statement as at 31 March.
