Chapter 2: Sources and Recording of Data — Part 2
Section 2.2 · Business Documents
Business documents are the sources of information for accounting. They provide the evidence that a transaction actually took place.
The Flow of Documents
When goods are traded on credit, a specific sequence of documents is issued between the buyer and the seller:
- Quotation: Sent by the seller to a potential buyer detailing prices and terms.
- Purchase Order: Sent by the buyer to the seller to order goods.
- Delivery Note: Sent by the seller with the goods. The buyer signs it to confirm receipt.
- Invoice: Sent by the seller to the buyer. This is the primary source document for credit sales/purchases and signifies a legal sale.
- Debit Note: Sent by the buyer to the seller to request a reduction in the invoice (e.g., if goods are faulty or overcharged).
- Credit Note: Sent by the seller to the buyer to confirm and accept a return or a reduction in the amount owed.
- Statement of Account: Sent monthly by the seller to the buyer as a summary of all transactions (invoices, credit notes, payments).
- Remittance Advice: Sent by the buyer to the seller with the payment to show which invoices are being paid.
Exam Traps
- Common Mistake: Students often confuse “Debit Notes” and “Credit Notes.” Remember: The buyer sends the Debit Note to ask; the seller sends the Credit Note to confirm.
Summary Table: Documents as Sources of Information
| Document | Book of Prime Entry | User |
|---|---|---|
| Sales Invoice | Sales Journal | Seller |
| Purchases Invoice | Purchases Journal | Buyer |
| Credit Note Issued | Sales Returns Journal | Seller |
| Credit Note Received | Purchases Returns Journal | Buyer |
| Cheque Counterfoil | Cash Book (Payments) | Payer |
| Paying-in Slip | Cash Book (Receipts) | Receiver |
| Bank Statement | Cash Book (Updates) | Business |
Bank Statement vs Statement of Account
These two documents are often confused in exams:
| Document | Issued By | Purpose |
|---|---|---|
| Bank Statement | The bank | Lists all transactions on the business bank account; used to update the Cash Book and prepare bank reconciliation |
| Statement of Account | The seller (supplier) | Monthly summary of invoices, credit notes, and payments owed between a buyer and seller on credit terms |
Business documents may be produced and recorded manually or digitally — the accounting treatment remains the same regardless of format.
Worked Example 1: Tracing a Credit Sale
Scenario: Seller A delivers goods worth $2,400 (after trade discount) to Buyer B on credit.
- Delivery Note sent with goods — Buyer B signs to confirm receipt.
- Invoice sent by Seller A for $2,400 — this is the primary source document.
- Seller A records the invoice in the Sales Journal, then posts: Dr Buyer B (debtor) $2,400; Cr Sales $2,400.
- Buyer B records the invoice in the Purchases Journal, then posts: Dr Purchases $2,400; Cr Seller A (creditor) $2,400.
Worked Example 2: Goods Returned
Scenario: Buyer B returns faulty goods worth $400 to Seller A.
- Buyer B sends a Debit Note to Seller A requesting a $400 reduction.
- Seller A sends a Credit Note for $400 to confirm the return.
- Seller A records in Sales Returns Journal: Dr Sales Returns $400; Cr Buyer B $400.
- Buyer B records in Purchases Returns Journal: Dr Seller A $400; Cr Purchases Returns $400.
