Ledger Posting
🟢 Lite — Quick Review (1h–1d)
Rapid summary for last-minute revision before your exam.
The ledger is the principal book of account where transactions are classified and collected. It contains all the asset, liability, capital, income, and expense accounts of a business. The process of transferring entries from the journal to the ledger is called posting. Each entry in the journal is posted to the relevant account(s) in the ledger, recording the date, the folio reference (J for journal page), and the amount.
Every ledger account has a debit (Dr.) side and a credit (Cr.) side. The side on which an amount is entered depends on the nature of the account:
| Account Type | Normal Balance | Increases on | Decreases on |
|---|---|---|---|
| Assets | Debit | Dr. | Cr. |
| Liabilities | Credit | Cr. | Dr. |
| Capital | Credit | Cr. | Dr. |
| Revenue/Income | Credit | Cr. | Dr. |
| Expenses | Debit | Dr. | Cr. |
Balancing an Account: Total the debits and credits. If debits exceed credits, the account has a debit balance (Dr). If credits exceed debits, it has a credit balance (Cr). For assets and expenses, a debit balance is the normal balance. For liabilities, capital, and income, a credit balance is normal.
⚡ Exam Tip: Always check whether an account is expected to have a debit or credit balance before you balance it. A sales account that ends up with a debit balance is unusual and should alert you to a posting error somewhere.

The Posting Process — Step by Step
- Open each ledger account in the general ledger (or appropriate subsidiary ledger for debtors and creditors)
- For each journal entry, identify the debited accounts — enter the amount on the debit side of each account, with the journal page reference
- For each journal entry, identify the credited accounts — enter the amount on the credit side of each account, with the journal page reference
- At the end of the period, balance each account by totalling both sides and calculating the difference
Format of a Ledger Account:
DR. PURCHASES ACCOUNT CR.
Date | Particulars | Folio | ₦ | Date | Particulars | Folio | ₦
--------------------------------------------------------------
Jan 1 | Bank/Cash | J001 | 50,000| Jan 31| Balance c/d | | 50,000
| | | | | | |
| | | 50,000| | | 50,000
Feb 1| Balance b/d | | 50,000| | | |Subsidiary Ledgers
For businesses with many debtors and creditors, a Sales Ledger (debtors’ ledger) and Purchases Ledger (creditors’ ledger) are maintained separately from the general ledger. The total of all debtors’ balances in the sales ledger should equal the Sundry Debtors balance in the general ledger. The same applies for creditors.
Credit Transactions — The Three-Column Ledger
The three-column format shows: date, particulars, folio, and a running debit/credit/balance column. This is useful for accounts that have many transactions, as the balance is always visible.
Balancing Example — Rent Account: If rent paid during the year totals ₦120,000 (all debits), and the account only has debits, the account has a debit balance of ₦120,000. This means rent expense for the period is ₦120,000 and will be transferred to the Income Statement.
Contra Entries
A contra entry occurs when the same amount appears in both the debit and credit columns of the same account. The most common contra is the cash discount — the discount allowed account is debited and the sundries column is credited to the extent of the discount. In a three-column cash book, the discount column is a contra: debits and credits in the discount columns are memorandum figures only.
⚡ Common Mistakes: Posting to the wrong side of an account (debit-credit reversal), carrying forward a balance without closing the account first, and forgetting to post the folio reference which makes it difficult to trace transactions back to the journal.

The Ledger in the Context of the Accounting System
The ledger represents the classification stage of the accounting cycle. Transactions are first recorded chronologically in the journal (book of original entry). They are then transferred (posted) to the ledger, where the same transactions are arranged chronologically by account. The ledger is therefore the book of final entry — the definitive record from which financial statements are prepared.
The Trial Balance Connection
All accounts in the ledger are balanced at the end of the period. The balances are then extracted and listed in a trial balance. The trial balance checks the arithmetic accuracy of the double-entry system — the total debits must equal total credits if all posting has been done correctly. However, a trial balance that agrees is no guarantee that the entries were correct in substance (errors of principle, errors of omission, and compensating errors can all exist even when the trial balance agrees).
Types of Errors Not Disclosed by a Trial Balance:
- Errors of Omission: Transaction completely omitted from the books — trial balance still agrees
- Errors of Commission: Wrong amount or wrong account, but the correct side — trial balance still agrees
- Errors of Principle: Capital expenditure treated as revenue expenditure (or vice versa) — both accounts are wrong sides, so trial balance still agrees
- Compensating Errors: Two errors that cancel each other out — trial balance still agrees
- Original Entry Error: Both debit and credit entries are recorded at the wrong amount — trial balance still agrees
Only errors that affect one debit and one credit unequally will cause the trial balance to disagree: errors of casting (adding up), posting (posting only one side), balancing (balancing incorrectly), and slide/dimension (moving a decimal point).
The Rectification Process
Errors found after posting require rectification through the journal. General rule: correct the account that was wrongly debited or credited. For example, if rent of ₦30,000 was posted to the Rates account:
- Dr. Rent a/c ₦30,000 (correcting the expense that was not charged)
- Cr. Rates a/c ₦30,000 (clearing the wrong charge)
Impersonal vs. Personal Accounts
- Impersonal accounts: Asset and expense accounts (can also include nominal accounts = incomes/losses)
- Personal accounts: Accounts of persons (debtors, creditors) and organisations
Traditional rules: debit the receiver, credit the giver (personal accounts); debit all expenses and losses, credit all incomes and gains (impersonal accounts).
Three-Column Cash Book — Special Considerations
The three-column cash book has columns for: Amount (debit side), Discount (credit side), Bank (debit side), and Amount (credit side), Discount (debit side), Cash (credit side). Contra entries occur when cash is paid into or withdrawn from the bank:
- Cash deposited into bank: Dr. Bank a/c (in cash book), Cr. Cash a/c (in cash book) — marked “C” for contra
- Cash withdrawn from bank: Dr. Cash a/c (in cash book), Cr. Bank a/c (in cash book) — marked “C” for contra
Compound Ledger Accounts
When a business has many transactions with a single debtor/creditor, it is impractical to open a full page account for each. A columnar ledger or a running balance account consolidates transactions in date order with a running balance column, saving space and time.
⚡ ICAN Exam Pattern: Ledger questions test both posting accuracy and the ability to identify and correct errors. A typical question involves posting a series of 10-15 transactions from a narrative, balancing the accounts, extracting a trial balance, and correcting three errors. Time management is essential — allow approximately 1 minute per ledger account and 5 minutes for the trial balance.
