Choosing the right source document

You know the document names but pick the wrong one when a question describes an event.

Match the document to the event, and to the side of the transaction you are on. A credit sale creates an invoice, a return creates a credit note, and a payment creates a receipt.

This lesson is part of the source documents chapter. The documents you choose here are recorded in the books of prime entry.

Which document belongs to which event?

Event Document Issued by
Goods sold on credit Invoice Seller
Goods sold for cash Cash bill Seller
Customer returns goods Credit note Seller
Payment received Receipt Person receiving the money
Cheque paid out Cheque counterfoil or payment voucher Payer
Cash banked Bank deposit slip Bank or depositor

Some textbooks also use a debit note to increase an amount owed, for example after an undercharge.

Worked example: one purchase, three documents

Hasnah’s Shop buys goods on credit from Sinar Borong. Follow the events in order.

  1. Sinar Borong delivers goods worth RM1 200. It issues an invoice, which Hasnah keeps as a purchase invoice.
  2. Hasnah returns damaged goods worth RM180. Sinar Borong issues a credit note for RM180.
  3. Hasnah pays the balance of 1 200 − 180 = RM1 020 by cheque. She keeps the cheque counterfoil, and Sinar Borong issues a receipt.

The same seller issues a different document at each event, and each one supports a different entry in the books.

The mistake that costs marks

The slip students make most is to name a receipt as the document for a credit sale. The customer has not yet paid, so there is nothing to receive.

Step Wrong Right
Event: goods sold on credit Receipt Invoice
What the document says “Payment received” “Payment is due”
When a receipt is used At the sale When the customer pays

A quick test is to ask whether money has moved. If it has, the document is a receipt or a cash bill. If it has not, it is an invoice or a credit note.

Check yourself

Name the source document for each event: (a) a customer buys RM60 of goods and pays cash at once, (b) a customer returns RM90 of goods bought on credit, (c) the business pays a supplier RM500 by cheque, (d) the business sells RM700 of goods to a customer on credit.

Answer

(a) Cash bill, since cash was paid at once. (b) Credit note, issued by the seller to reduce the amount owed. (c) Cheque counterfoil or payment voucher, kept by the payer. (d) Invoice, because the customer has not yet paid.

What to study next

Next, read what each document shows in reading invoices, credit notes and receipts. You can log any wrong choice in the mistake log and paper-error review tool.

Common questions

What is the difference between an invoice and a receipt?

An invoice is a request for payment, issued when goods are sold on credit. A receipt is proof that payment has been made. An invoice comes first in a credit sale, and the receipt comes when the customer pays.

Who issues a credit note?

The seller issues a credit note to the buyer when goods are returned or the amount charged is reduced. It lowers the amount the buyer owes. The buyer keeps it as the source document for the return.

What document supports a cash sale?

A cash bill or cash receipt, given to the customer at the time of sale. It is proof of the sale and of the payment together, because no credit is involved.

What is a debit note?

It is a document that increases the amount owed, for example after an undercharge. Textbooks use it a little differently, so follow your own textbook's definition when a question names one.

If the choice of document slips when the wording of an event changes, a one-to-one Accounting teacher can give you unfamiliar events and ask you to justify each document choice.
