- Debit side: records discounts allowed, cash received and money paid into the bank.
- Credit side: records discounts received, cash paid and money paid out of the bank.
- Discount columns: memoranda only, so their totals are taken to the ledger discount accounts.

What is a three-column cash book?
A three-column cash book is a cash book that adds a discount column to the cash and bank columns on each side.
- Discount allowed column: on the debit (left) side.
- Discount received column: on the credit (right) side.
- Double entry: the principle of double entry also applies in this cash book.
- Memoranda: the discount columns look like account columns but are only memoranda.
- Periodic totals: totals from the discount columns are entered into the discount accounts.

What are the columns of a three-column cash book?
There are three money columns on each side: discount, cash and bank.
| Column | Debit side | Credit side |
|---|---|---|
| Discount | Discount allowed | Discount received |
| Cash | Cash received | Cash paid out |
| Bank | Cheques and cash paid into the bank | Cheques issued and cash withdrawn |
- Date: the day the transaction took place.
- Details: the name of the account affected.
- Folio: the page number of the ledger account, used for cross-reference.
How are the discount columns treated in the cash book?
The discount columns are totalled and not balanced.
- Why not balanced: the columns only collect figures, so there is no opening balance to carry down.
- When totalled: weekly or monthly, when the cash and bank columns are balanced and ruled off.
- Where posted: the totals go to the discount accounts in the ledger.
- Which side: each total is entered on the same side of the discount account as in the cash book.
| Cash book column | Ledger account | Side in ledger |
|---|---|---|
| Discount allowed total | Discount allowed account | Debit |
| Discount received total | Discount received account | Credit |
- Personal accounts: a debtor’s account is credited with the cash and the discount allowed.
- Creditor’s account: it is debited with the cash and the discount received.
What are discounts?
Discounts are allowances, in the form of a deduction in price or a percentage payment, made to retailers by suppliers or manufacturers.
What are the types of discounts?
There are two types of discount: cash discount and trade discount.
1. What is cash discount?
A cash discount is an allowance given in return for prompt payment.
- Who gives it: businesses or suppliers, when buyers pay immediately or within a set period.
- Period: the set period may be from 7 days to 30 days.
- Entered in cash book: yes, in the discount columns.
Discount allowed
Discount allowed is a reduction in the cash a debtor pays for prompt payment.
- Entry: the amount is entered in the discount allowed column on the debit side.
- Nature: it is a cost to the business that allows it.
Discount received
Discount received is the reduction a trader gets off accounts paid to a creditor.
- Entry: the amount is entered in the discount received column on the credit side.
- Nature: it is a gain to the business that receives it.
2. What is trade discount?
A trade discount is a reduction from the retail list price offered to a trader.
- Who gives it: manufacturers or suppliers, as a deduction from catalogue prices.
- Gross selling price: the catalogue or list price.
- Net selling price: the price after the trade discount is deducted.
- Entered in cash book: no, trade discounts are not entered in the cash book.
- Example: list price ₦10,000 less 10% trade discount (₦1,000) gives a net price of ₦9,000.
