Accounting is built on accuracy and balance. Even with a well-designed accounting system, errors may occur during the recording and posting of transactions. The trial balance serves as a critical checkpoint in the accounting cycle, allowing accountants to verify the arithmetical accuracy of ledger entries before preparing financial statements.
This chapter explains the purpose and preparation of a trial balance, examines common accounting errors, and outlines systematic techniques for identifying and correcting errors, including the use of a suspense account.
5.2 Purpose of the Trial Balance
A trial balance is a statement that lists all ledger account balances at a particular date, with debit balances in one column and credit balances in another.
Objectives of Preparing a Trial Balance
- To check the arithmetical accuracy of ledger postings
- To ensure that total debits equal total credits
- To serve as a basis for preparing financial statements
- To assist in the detection of accounting errors
⚠️ Important: A balanced trial balance does not guarantee that the accounts are free from all errors.
5.3 Preparation of a Trial Balance
5.3.1 Steps in Preparing a Trial Balance
- Balance all ledger accounts
- Extract debit and credit balances
- List the balances in the trial balance format
- Total both columns
- Compare totals
5.3.2 Format of a Trial Balance (Ledger Style Presentation)
DEBIT BALANCES SECTION
- Cash and Bank: K18,500
- Accounts Receivable: K12,000
- Inventory: K25,000
- Equipment: K40,000
- Rent Expense: K8,500
TOTAL DEBIT BALANCES: K104,000
CREDIT BALANCES SECTION
- Accounts Payable: K15,000
- Capital: K60,000
- Sales Revenue: K32,000
TOTAL CREDIT BALANCES: K107,000
CHECK: The trial balance does NOT agree. Credits exceed debits by K3,000.
To temporarily balance the books, a Suspense Account is created with a debit balance of K3,000.
Adjusted Totals: Debits K104,000 + K3,000 = K107,000 = Credits K107,000
5.4 Common Types of Accounting Errors
Accounting errors may occur at various stages of the accounting process. These errors can be classified based on whether they affect the trial balance.
5.4.1 Errors That Do NOT Affect Trial Balance Agreement
These errors maintain the equality of debits and credits but still represent incorrect accounting:
- Error of Omission - Transaction completely omitted
- Example: A-cash sale is not recorded in any account.
- Error of Commission - Correct amount, wrong account of same type
- Example: Cash paid for electricity (K500) debited to Telephone Expense instead of Electricity Expense.

———————————————————————-
3. Error of Principle - Wrong account type
Example: Purchase of machinery (capital expenditure) recorded as a repair expense (revenue expenditure).
4. Compensating Errors - Two errors that cancel each other
Example: Sales overstated by K1,000 and Purchases overstated by K1,000.
5.4.2 Errors That DO Affect Trial Balance Agreement
These errors cause the trial balance totals to disagree:
- Partial Omission (Single Entry) - Only one side of entry recorded
- Wrong Casting - Incorrect totaling of ledger account
- Wrong Balancing - Ledger balance miscalculated
- Transposition Errors - Digits reversed (e.g., K540 recorded as K450)
- Slide Errors - Decimal misplaced (e.g., K100.00 recorded as K10.00)
5.5 Techniques for Identifying Errors
When a trial balance does not balance, systematic investigation is required.
Common Error-Detection Techniques
- Re-addition of trial balance columns
- Checking ledger balancing
- Verifying journal entries
- Confirming posting accuracy
- Checking for transposition and slide errors
- Dividing difference by 2 - May indicate a balance placed in wrong column
- Dividing difference by 9 - May indicate transposition or slide error
5.6 Rectification of Accounting Errors
Rectification depends on when the error is discovered and whether it affects the trial balance.
5.6.1 Rectification Before Final Accounts
Errors are corrected using journal entries.
Example: Error of Principle
Error: Purchase of machinery K12,000 debited to Purchases Account.
Incorrect Original Entry:

5.6.2 Rectification After Final Accounts
Errors affecting profits require adjustment through the Profit and Loss Adjustment Account.
5.7 Suspense Account
5.7.1 Meaning and Purpose
A suspense account is a temporary account used to balance the trial balance when the cause of the difference is not immediately known.
5.7.2 Opening a Suspense Account
Situation: Trial balance shows debit total K100,000, credit total K103,500. Difference: K3,500 (credits higher).
Entry to Open Suspense Account:
- Dr Suspense Account K3,500
- [Various accounts credited to balance]

5.7.3 Clearing the Suspense Account
When errors are found, correction entries are made and posted to the suspense account until it has a zero balance.
Example Error Found: Rent K3,500 debited correctly but not credited to cash.
Correction Entry:
- Dr Suspense Account K3,500
- Cr Cash K3,500

5.8 Worked Numerical Example
Question
A trial balance showed a debit excess of K2,000. The following errors were discovered:
- Cash sale K1,200 posted to sales account only (single entry)
- Discount received K800 debited to Discounts Allowed instead of credited to Discounts Received
Solution & Journal Entries
1. Correction for single entry error:
- Dr Suspense Account K1,200
- Cr Sales K1,200
2. Correction for wrong posting of discount:
Original incorrect entry was:
- Dr Discounts Allowed K800
- Cr Cash K800
Correction requires:
- Cancel the incorrect debit to Discounts Allowed
- Create correct credit to Discounts Received
- Adjust suspense for net effect
Combined correction entry:
- Dr Suspense Account K1,600 (K800 × 2)
- Cr Discounts Allowed K800
- Cr Discounts Received K800
Suspense Account after corrections
