Example 1: Sequencing the Credit-Transaction Document Flow
Question
Solution plan
A credit transaction flows from the buyer enquiring to final payment. HOTS key: identify the direction of each document (buyer->seller or seller->buyer) and link its function to the transaction stage (enquiry, offer, order, delivery, claim, statement, payment).
| Order | Document | Prepared by | Received by | Function |
|---|---|---|---|---|
| 1 | Enquiry Letter | Buyer | Seller | Enquires about price, terms of sale and discount |
| 2 | Quotation | Seller | Buyer | States price, trade discount and terms |
| 3 | Order Form | Buyer | Seller | Formally places the order for goods |
| 4 | Invoice | Seller | Buyer | States credit-sale details and amount owed |
| 5 | Delivery Note | Seller | Buyer | Confirms delivery and receipt of goods |
| 6 | Statement of Account | Seller | Buyer | Summarises transactions and the balance owed for the period |
| 7 | Receipt | Seller | Buyer | Confirms that payment has been received |
The invoice is the key credit-transaction document; in a cash transaction the invoice and statement are replaced by a cash bill.
Answer
Correct order: Enquiry Letter, Quotation, Order Form, Invoice, Delivery Note, Statement of Account, Receipt. Documents 1 and 3 are prepared by the buyer; the rest by the seller.

Example 2: Completing a Cash Bill with Trade and Cash Discount
Question
Solution plan
The order of computation must be exact: (1) total the list price, (2) deduct trade discount on the list price to get the net price (bill value), (3) deduct cash discount on the net price. Trade discount is never recorded in the accounts; only the net value becomes sales.
| Details | Amount (RM) |
|---|---|
| 4 ceiling fans @ RM250 | 1,000 |
| 2 water heaters @ RM150 | 300 |
| Total list price | 1,300 |
| Less: Trade discount 10% | 130 |
| Net price (bill value) | 1,170 |
| Less: Cash discount 4% | 46.80 |
| Amount payable | 1,123.20 |
The RM130 trade discount enters no account; sales are recorded at RM1,170. The RM46.80 cash discount is recorded in the Discount Allowed account.
Answer
Total list price RM1,300; net price after trade discount RM1,170; amount payable after 4% cash discount is RM1,123.20.

Example 3: Detecting and Correcting a Discount Calculation Error
Question
Solution plan
Two errors: (1) the base/order of discounts: cash discount must be computed on the net price (after trade discount), not on the list price; (2) trade discount is never recorded in the accounts. Recompute: list price - trade discount = net price; then cash discount on the net price.
| Details | Clerk (wrong) | Correct |
|---|---|---|
| List price | 4,000 | 4,000 |
| Less: Trade discount 20% | 800 | 800 |
| Net price (invoice value) | 3,200 | 3,200 |
| Less: Cash discount 5% | 200 | 160 |
| Amount paid | 3,000 | 3,040 |
Clerk's error: the 5% cash discount was computed on RM4,000 (=RM200) when it should be on RM3,200 (=RM160); payment understated by RM40. The RM800 trade discount is not entered in any account; only the net RM3,200 is recorded as purchases.
Answer
Correct computation: net price RM3,200, cash discount RM160, amount that should be paid RM3,040. The clerk underpaid by RM40 and wrongly recorded the RM800 trade discount as an expense.

Example 4: Interpreting a Statement of Account and Verifying the Balance
Question
Solution plan
A Statement of Account is a non-source document: a summary of transactions from the seller's view. Debit increases the customer's debt (invoice); credit reduces it (credit note, payment receipt). Compute the running balance: balance + invoice - credit note - payment.
| Date | Particulars | Debit | Credit | Balance |
|---|---|---|---|---|
| 1 May | Balance b/f | 1,200 | ||
| 5 May | Invoice No. 101 | 2,500 | 3,700 | |
| 10 May | Credit Note (returns) | 300 | 3,400 | |
| 20 May | Receipt (payment) | 1,200 | 2,200 | |
| 31 May | Balance owing | 2,200 |
The Statement of Account is not a source document, so it is not used to make entries in the books of prime entry. It merely reminds the customer of the balance owing.
Answer
The balance owing at 31 May 2026 is RM2,200. It means Kedai Jahit Salmah still owes RM2,200 to Perniagaan Tekstil Melur and must settle it.

Example 5: Interpreting a Bank Statement and Explaining Differences
Question
Solution plan
A Bank Statement is a non-source document issued by the bank. Items causing a permanent difference (bank charge, interest) are not yet in the cash book and must be adjusted. Timing items (uncredited deposit, unpresented cheque) are merely timing differences: both records are correct and no extra cash-book entry is needed.
| Details | Effect on cash book | Amount (RM) |
|---|---|---|
| Cash-book balance (before) | - | 3,500 |
| Bank service charge | Less | 50 |
| Bank interest received | Add | 20 |
| Adjusted cash-book balance | - | 3,470 |
| Timing-difference items (no cash-book adjustment) | ||
| Uncredited deposit | No effect | 800 |
| Issued cheque not yet presented | No effect | 400 |
The uncredited deposit and the unpresented cheque are already recorded in the cash book; the difference exists only because the bank has not yet processed them. They clear by themselves, so no extra entry is made.
Answer
The adjusted cash-book balance is RM3,470 (RM3,500 - RM50 charge + RM20 interest). The RM800 uncredited deposit and RM400 unpresented cheque are timing differences and are not adjusted in the cash book.

Example 6: Evaluating Cash-Discount Eligibility Based on Payment Date
Question
Solution plan
HOTS steps: (1) count the days from invoice date to payment date, (2) compare with the 14-day term to decide eligibility, (3) compute net price (list price - trade discount), (4) deduct cash discount only if eligible. Invoice A: 3->15 May = 12 days (eligible). Invoice B: 4->25 May = 21 days (not eligible).
| Details | Amount (RM) |
|---|---|
| List price | 6,000 |
| Less: Trade discount 15% | 900 |
| Net price (invoice value) | 5,100 |
| Less: Cash discount 5% (eligible) | 255 |
| Amount paid | 4,845 |
From 3 May to 15 May = 12 days, within the 14-day limit, so the cash discount is allowed.
| Details | Amount (RM) |
|---|---|
| List price | 2,000 |
| Less: Trade discount 10% | 200 |
| Net price (invoice value) | 1,800 |
| Cash discount (not eligible) | 0 |
| Amount paid | 1,800 |
From 4 May to 25 May = 21 days, exceeding the 14-day limit, so no cash discount; the full net price of RM1,800 is paid.
Answer
Invoice A: eligible for cash discount (12 days), amount paid RM4,845. Invoice B: not eligible (21 days), full amount paid RM1,800.
