Accounting - Term 2 - Week 7

Imagine Thandi runs a tuck shop in Soweto and buys stock from a supplier in Polokwane. She receives a printed invoice and a till slip. These papers are not just for show—they are proof of the transaction and the first step in her accounting records. Without these, she could forget what she bought, or worse, lose money through errors or fraud. In South Africa, source documents like cash slips, invoices, and EFT confirmations are essential for tracking every cent, especially with load-shedding causing disruptions. The rule: every transaction must have a valid source document. Many learners think only big businesses need this, but even a spaza shop or a minibus taxi owner must keep records to survive and grow. If Thandi is ever audited by SARS, she must produce these documents as proof. Without them, she risks penalties or losing out on tax deductions. This is why every business, no matter how small, needs to treat source documents seriously.

Picture Ahmed, who owns a cellphone repair shop in Durban. He deals with cash sales, EFTs, and sometimes gives credit. Each transaction generates a different document: a cash slip for cash sales, an EFT proof for electronic payments, and an invoice for credit sales. These documents contain key details: date, amount, parties involved, and a unique number. A common misconception is that all receipts are the same. In reality, each document serves a specific purpose and must be matched to the correct journal. For example, a cash slip goes to the Cash Receipts Journal, while an invoice for goods sold on credit goes to the Debtors Journal. Mixing these up leads to errors in financial statements. For instance, if Ahmed records an EFT payment in the wrong journal, his accounts will not balance, and he could make costly mistakes. Understanding the difference between these documents is crucial for accurate bookkeeping and for answering NSC exam questions correctly.

Let’s say Sipho, a minibus taxi owner in Mthatha, buys new tyres. He pays by EFT and receives an emailed proof of payment. Before recording, he checks: Is the date correct? Does the amount match the supplier’s invoice? Is the supplier’s name clear? Only after confirming these details does he record the transaction in the Cash Payments Journal. The process: check the document, extract the information, and enter it in the right place. Many learners skip the checking step, leading to mistakes like recording the wrong amount or date. Always verify before you record—this is what exam markers look for in Paper 1. For example, if Sipho accidentally records the payment in the Cash Receipts Journal, his books will show more income than he actually earned. This could lead to confusion, incorrect tax calculations, and even trouble with SARS. Careful analysis and recording are the foundation of trustworthy accounting.

Step 1: Thandi sells chips and cooldrinks for R120 cash. She issues a till slip to the customer. (Reason: The till slip is proof of the cash sale and is required for accurate record-keeping.) Step 2: She checks the slip: date is today, amount is R120, and her business name is on it. (Reason: Ensures accuracy and completeness before recording, which prevents errors.) Step 3: She records the R120 in the Cash Receipts Journal under 'Sales'. (Reason: Cash sales are always entered in the Cash Receipts Journal, not in any other journal.) Final answer: The transaction is correctly recorded in the CRJ. Sanity check: The cash in the till matches the slip, and the journal entry matches the amount on the slip. This double-check helps avoid mistakes and is good practice for exams.

Step 1: Ahmed pays R850 by EFT for cellphone parts. He receives an emailed proof of payment from his bank. (Reason: EFT proof is the official source document for this transaction and must be kept for records.) Step 2: He checks: date matches the supplier’s invoice, amount is R850, supplier’s name is correct, and reference number is present. (Reason: Verifying all details prevents recording errors and ensures the document is valid.) Step 3: He records R850 in the Cash Payments Journal under 'Trading Stock'. (Reason: Payments for stock are always entered in the Cash Payments Journal.) Final answer: The payment is correctly recorded. Sanity check: Ahmed compares his bank statement to the journal entry to confirm the payment went through and matches the amount recorded. This is essential for both business accuracy and exam success.

Question: Sipho receives an invoice for R2,000 for minibus repairs, to be paid next month. Which journal does this go to? Model thinking: An invoice for credit purchases is always recorded in the Creditors Journal, not in the Cash Payments Journal because payment has not yet been made. Worked response: The invoice is recorded in the Creditors Journal for R2,000, under the repairs account. Now you try: Lerato buys office supplies on credit for R500 and receives an invoice. Which journal? Answer: Creditors Journal. This is because the purchase was on credit, not cash.

Question: Ahmed receives a cash slip for R300, but the slip has no date. Is this valid? Model thinking: A valid source document must have a date, amount, parties, and signature or business name. Missing any of these makes it invalid for accounting. Worked response: No, this slip is not valid for accounting records because the date is missing. He should request a new slip with the correct details. Now you try: Thandi gets an EFT proof with the wrong supplier name. Is it valid? Answer: No, the supplier name must be correct for the document to be valid. Otherwise, it cannot be used.

1. List three types of source documents used in South African businesses, such as a till slip, invoice, and EFT proof. 2. State which journal a cash slip should be recorded in and explain your answer. 3. Name two details every valid source document must have, and give a reason why each is important.

1. Classify each: a) Invoice for goods sold on credit, b) EFT proof for payment to supplier, c) Till slip for cash sale. Write which journal each belongs to. 2. Identify the error: A receipt missing the amount. Explain why this is a problem for accounting. 3. Explain why a handwritten note without a signature is not valid as a source document, using an example.

1. Analyse this: Sipho receives a supplier invoice for R1,500, but the date is last year. What should he do, and why? 2. Determine which journal and account to use: Ahmed pays R400 cash for advertising and receives a till slip. Show your reasoning. 3. Justify the importance of matching source documents to the correct journals in preparing for the NSC exam. Give two reasons.

• EFT proof
• Invoice
• Cash slip
• Bank deposit slip

Answer: Invoice

An invoice is used for credit transactions, not cash payments. Many confuse invoices with receipts, but they serve different purposes. In exams, always check if the transaction is cash or credit before choosing the document.

• Valid
• Invalid
• Acceptable if signed
• Valid for cash sales only

Answer: Invalid

A valid source document must include the business name. Missing details make it invalid, even if signed. This is a common NSC exam trap—always check for all required details.

• Cash Receipts Journal
• Debtors Journal
• Creditors Journal
• Petty Cash Journal

Answer: Creditors Journal

Invoices for credit purchases go to the Creditors Journal. Learners often confuse this with the Debtors Journal, but Debtors Journal is for credit sales, not purchases.

• File the document
• Check for completeness and accuracy
• Enter the amount
• Ask your manager

Answer: Check for completeness and accuracy

Always check details first. Skipping this leads to errors, a common mistake in exams. If you record before checking, you might enter incorrect information, which can affect your marks and the business’s records.

• Valid
• Invalid
• Valid if amount is correct
• Valid if signed

Answer: Invalid

A missing date makes any source document invalid, even if other details are correct. This is because the date is needed to prove when the transaction happened, which is essential for accounting and tax purposes.
