What this dot point is asking
You need to identify common business documents - the order form, invoice, receipt, and memo - and describe the purpose of each. These are the everyday documents a business uses when it buys, sells, and communicates. Keep your answer practical and clear, learn what each document is for, and be ready to explain the difference between an invoice (a request for payment) and a receipt (proof of payment).
The answer
What business documents are
Business documents are the written or printed records a business uses to buy, sell, pay, and communicate. They keep a clear record of what happened, which protects both the business and the customer. Many are now sent electronically by email.
Order form
An order form is used to order goods. The buyer fills it in to say what they want and how many. For example, a cafe sends an order form to its supplier listing the flour, milk, and coffee it needs. The order form starts the buying process.
Invoice
An invoice is sent by the seller to ask the buyer to pay. It lists the goods supplied and the amount owed. It is a request for payment, sent before the buyer has paid. For example, after delivering the coffee, the supplier sends the cafe an invoice for 300 dollars.
Receipt
A receipt is given as proof that payment has been made. It is given after the buyer has paid. For example, once the cafe pays the 300 dollars, the supplier gives a receipt showing the payment was received. A receipt protects the buyer by proving they paid.
The difference between an invoice and a receipt
This difference is important: an invoice asks for payment (before paying), while a receipt proves payment was made (after paying). They come at different stages.
Memo
A memo (short for memorandum) is a short note used inside a business to pass a message to staff, for example reminding everyone of a meeting or a change in opening hours. A memo is for internal communication, not for customers.
Why keeping documents matters
Keeping business documents is important because they:
- Are a record of what was bought, sold, and paid, which helps check the money.
- Are proof if there is a disagreement, for example over whether payment was made.
- Help with accounts and records, including working out profit.
Examples in context
Example 1. A restaurant ordering supplies. A restaurant sends an order form to its vegetable supplier for the week's produce. The supplier delivers and sends an invoice asking for payment. The restaurant pays and receives a receipt as proof. Weeks later, when the supplier wrongly claims a bill is unpaid, the receipt settles it instantly, showing why documents are kept.
Example 2. A shop manager using a memo. A shop manager needs to tell all staff that opening hours will change next week. She sends a short memo to the team rather than telling each person separately. The memo is quick, clear, and reaches everyone inside the business, which is exactly what an internal document is for.
Try this
Cue. State what an invoice is and what a receipt is, and explain how they differ. Remember an invoice is a request for payment before paying, and a receipt is proof of payment after paying.
Cue. Identify three business documents and state the purpose of each. Cover an order form, an invoice, a receipt, or a memo, giving a clear one-line purpose for each rather than just the name.
Cue. Explain why a business should keep its documents. Link keeping documents to having a record of money, having proof in a disagreement, and helping with accounts and working out profit.

What markers reward: a correct purpose of an invoice (a request for payment listing goods and amount owed), a correct purpose of a receipt (proof of payment), and a clear difference (invoice asks for payment, receipt proves it was paid).
