Accounting - Term 1 - Week 9

Imagine Thandi buys airtime at her local spaza shop in Mthatha. She receives a till slip showing the date, amount paid, and the shop’s name. This slip isn’t just paper—it’s proof of her transaction. In accounting, these slips, invoices, and receipts are called source documents. Businesses in South Africa—from minibus taxi owners in Khayelitsha to supermarkets in Polokwane—use them to record every sale and purchase. Without these documents, it’s easy to forget details or make mistakes. Source documents provide the evidence needed for accurate accounting, tax returns, and even for resolving disputes. A common misconception is that only big businesses need to keep these records. In reality, even small businesses must keep source documents for at least five years, as required by SARS (South African Revenue Service). If you lose them, you might not be able to claim expenses or prove your income, which can lead to penalties or missed opportunities.

Sipho runs a minibus taxi in Soweto. Each time a passenger pays, he gives a receipt. When he buys fuel, he gets a cash slip. Lerato’s tuckshop in Durban uses tax invoices when selling goods to other shops. The main types of source documents you’ll see in South Africa are: cash slips (for cash sales), receipts (proof of payment), tax invoices (for sales involving VAT), credit notes (for returns), and cheque counterfoils (for payments by cheque, though these are rare now). Each document has unique features. For example, a tax invoice must show the words 'TAX INVOICE', the seller’s VAT number, date, and amount including VAT. Recognising these differences helps you record transactions correctly and avoid confusion. If you mix them up, you might record a sale as a purchase or vice versa, which can cause errors in your books and problems during audits.

Ahmed buys groceries for his shop in Polokwane and receives a tax invoice. To record this transaction, he checks for the date, seller’s name, VAT number, description of goods, quantity, unit price, total amount, and VAT amount. Missing or incorrect details can lead to SARS rejecting the expense claim. Always check the document for errors—like a missing VAT number or incorrect date. Many learners mistakenly think the total is always the amount to record, but sometimes discounts or VAT must be considered. Carefully extract all relevant details before recording the transaction in the accounting records. For example, if the invoice shows a discount, make sure you record the discounted amount, not the original price. This attention to detail ensures your records are accurate and accepted by SARS.

Step 1: Thandi buys cooldrinks for R120 cash at a spaza shop in Khayelitsha. She receives a cash slip dated 5 March 2024. Step 2: Identify key details: date (5 March 2024), amount (R120), seller (Spaza Shop), items (cooldrinks). Reason: These details prove the transaction occurred. Step 3: Record in the cash payments journal: Date: 5 March 2024, Details: Cooldrinks, Amount: R120. Reason: Cash slips are used for cash purchases. Final answer: The transaction is recorded as a cash purchase of cooldrinks for R120 on 5 March 2024. Sanity check: The slip has all required details, and the amount matches the purchase.

Step 1: Ahmed buys cleaning supplies for his Durban shop. Tax invoice: Date: 10 March 2024, Amount: R230 (including R30 VAT), Seller: CleanCo, VAT number: 4567891234. Step 2: Identify net amount: R230 - R30 = R200. Reason: VAT must be separated for correct recording. Step 3: Record in purchases journal: Date: 10 March 2024, Details: Cleaning supplies, Net amount: R200, VAT: R30, Total: R230. Reason: This matches the tax invoice and SARS requirements. Final answer: Cleaning supplies purchased for R200 plus R30 VAT, total R230, recorded on 10 March 2024. Sanity check: All amounts add up, and VAT is shown separately.

Question: Sipho pays R50 for a taxi ride from Soweto to Johannesburg and receives a receipt dated 12 March 2024. How should this be recorded? Let’s think: What type of document is this? A receipt for a cash payment. What details do we need? Date, amount, reason (taxi fare). Worked response: Record in cash payments journal: Date: 12 March 2024, Details: Taxi fare, Amount: R50. Now you try: Sipho buys airtime for R30 cash and receives a receipt dated 13 March 2024. How should this be recorded? Answer: Record in cash payments journal: Date: 13 March 2024, Details: Airtime, Amount: R30.

Question: Lerato buys stationery for her tuckshop. Tax invoice: Date: 15 March 2024, Amount: R150 (after R20 discount), VAT: R19.65, Seller: Stationery World. How do we record this? Let’s think: Is the discount already included? Yes. What is the net amount? R150 - R19.65 = R130.35 (excluding VAT). Worked response: Record in purchases journal: Date: 15 March 2024, Details: Stationery, Net amount: R130.35, VAT: R19.65, Total: R150. Now you try: Ahmed buys printer paper for R200 (including R26 VAT) on 16 March 2024. How do you record this? Answer: Net amount: R174, VAT: R26, Total: R200, Date: 16 March 2024.

1. List three types of source documents used in South African businesses, such as cash slips, tax invoices, and receipts. 2. Identify two key details found on a cash slip, like the date and the amount. 3. State why it’s important to keep source documents, especially for SARS and to prove transactions.

1. Given a tax invoice for R300 (including R39 VAT), record the net amount, VAT, and total in the correct format. 2. Explain what could happen if a business loses its source documents, considering SARS requirements. 3. Identify the error if a learner records the gross amount as net sales, and describe the impact on financial statements.

1. Analyse a receipt showing R500 for goods, but the date is missing. What should the business do to fix this? 2. Compare a cash slip and a tax invoice—explain when each would be used in a real business scenario. 3. Solve: Lerato returns goods worth R120 (including R15 VAT) and receives a credit note. How should this be recorded in the journals? Give full details.

• Tax invoice
• Cash slip
• Credit note
• Cheque counterfoil

Answer: Cash slip

A cash slip is issued for cash purchases like fuel. Many confuse it with a tax invoice, but tax invoices are for VAT-registered sales.

• Customer's ID number
• Seller's VAT number
• Bank account number
• Customer's address

Answer: Seller's VAT number

The seller's VAT number is required by SARS. Learners often think the customer's details are needed, but it's the seller's VAT number that matters.

• Income is understated
• VAT is understated
• Income is overstated
• No effect

Answer: Income is overstated

Recording the gross as net sales overstates income and VAT. Many think it has no effect, but it leads to errors in financial statements.

• Receipt
• Credit note
• Cash slip
• Tax invoice

Answer: Credit note

A credit note is issued for returns. Learners often confuse it with a receipt, but receipts are for payments received.

• Proof for SARS
• Evidence in disputes
• To decorate the office
• To record transactions

Answer: To decorate the office

Source documents are not kept for decoration. They serve as legal and financial evidence for SARS, help resolve disputes, and are essential for recording transactions accurately. Keeping them for decoration is not a valid or practical reason, but some learners may not realise the legal importance of these documents.
