The ledger is a book of accounts where business transactions are recorded in a systematic way. It contains all the accounts needed to prepare the trial balance and financial statements.

Importance of the Ledger

• Shows the total purchases and sales for a specific period
• Records all expenses and income
• Helps check the arithmetical accuracy of records
• Provides information needed to prepare trial balance

Types of Ledger

1. Sales Ledger – Contains personal accounts of credit customers (debtors)
2. Purchases Ledger – Contains personal accounts of credit suppliers (creditors)
3. General Ledger – Contains all other accounts (assets, expenses, income)

Classification of Accounts

These are the first books where transactions are recorded. They include:

• Cash Book – for cash and bank transactions
• Sales Day Book – for credit sales
• Purchases Day Book – for credit purchases
• Sales Returns Day Book – for goods returned by customers
• Purchases Returns Day Book – for goods returned to suppliers

Each entry in these books must later be posted to the relevant ledger account.

When posting from books of original entry to the ledger, follow these rules:

1. Locate the account to be debited in the ledger
2. Enter the date in the date column
3. Enter the amount in the Debit (Dr) column
4. Write the source document reference in the Folio column
5. Write a brief description in the Details column
6. Repeat the same process for the credit entry in the corresponding account

Key Principle

Every debit entry must have a corresponding credit entry (Double Entry System)

The following transactions were recorded in the Cash Book for Mwanzo Small Business in May 2023:

After posting all transactions, each account should be balanced off to show the closing balance. This is done to find out the net position of each account at the end of a period.

Steps to Balance an Account

1. Total both sides – Add up all the debit entries and all credit entries separately
2. Find the difference – Subtract the smaller total from the larger total
3. Enter the balance – If the debit side is larger, write the difference on the credit side as "Balance c/d" (carried down). If the credit side is larger, write the difference on the debit side
4. Show the totals – Draw double lines under the totals on both sides
5. Bring down the balance – On the opposite side of the next period, write "Balance b/d" (brought down)

Example: Balancing the Cash Account

From the Cash Account above:

• Total Debit: 150,000 + 120,000 + 200,000 = 470,000
• Total Credit: 80,000 + 25,000 + 15,000 = 120,000
• Difference: 470,000 - 120,000 = 350,000

The larger side is Debit, so the closing balance is Tsh 350,000 (Dr).

The balance is entered on the credit side as "Balance c/d" and brought down on the debit side of the next period as "Balance b/d".

• Posting is transferring information from books of original entry to the ledger
• Every debit must have a corresponding credit (double entry)
• Folio column links the ledger to the source document
• Balancing shows the net position of each account
• Properly posted and balanced accounts are needed to prepare accurate financial statements

In Tanzania, small businesses such as dukas in Kariakoo or mopeds spare parts shops in Mwanza use this posting method to track whether they made profit or loss during a month. For example, a shopkeeper recording daily sales in a notebook (book of original entry) then updating separate pages for each customer and expense item (ledger accounts) can see exactly how much money is owed by customers and how much they owe suppliers at the end of the month, helping them plan purchases and payments.
