What Are Business Documents?

Business documents are official papers (or digital records) that businesses use to record and communicate information about transactions — meaning any time money, goods, or services change hands.

Every time a business buys or sells something, a document is created. These documents are important because they:

  • Keep a permanent record of every transaction
  • Can be checked later to spot mistakes or missing payments
  • Provide the information that accountants use to enter transactions into the accounting books
  • Act as proof that a transaction actually happened

Think of them like receipts or notes that say: "This happened, on this date, for this amount."

Types of Business Transactions

Before looking at individual documents, it helps to know there are two main types of transactions:

  • Credit transactions — The buyer takes the goods now and pays later. Documents like invoices, debit notes, credit notes, and statements of account are used here.
  • Cash transactions — The buyer pays immediately (using cash, cheque, or bank transfer). Documents like receipts, cheques, cheque counterfoils, paying-in slips, and bank statements are used here.

1.1 The Invoice

What is an invoice?

An invoice is a document that the supplier (the person or business selling the goods) sends to the customer (the buyer). It is basically a bill — it tells the customer exactly what they have bought and how much they owe.

  • The customer receives the invoice and calls it a purchases invoice (because it relates to their purchase).
  • The supplier keeps a copy and calls it a sales invoice (because it relates to their sale).

When is an invoice used?

An invoice is issued when goods or services are sold on credit — meaning the customer will pay later, not immediately.

What information does an invoice contain?

A complete invoice will include all of the following:

  • Date — The date the transaction took place
  • Supplier's details — Name and address of the seller
  • Customer's details — Name and address of the buyer
  • Description of goods — What was sold, including the quantity (how many) and the unit price (the price of one item)
  • Trade discount — A reduction in price that is subtracted before the total is calculated (explained in detail below)
  • Total amount owed — The final amount the customer must pay
  • Payment terms — The deadline for paying, and whether a cash discount is available for paying early

What is a trade discount?

A trade discount is a reduction (a price cut) given by the supplier to the customer. It might be given because:

  • The customer is buying a large quantity of goods (buying in bulk)
  • The customer is a regular, loyal buyer

Important points about trade discount:

  • It is deducted (taken away) from the price before the invoice total is worked out
  • Only the final price after the trade discount is recorded in the accounting books
  • The amount of the trade discount itself is not recorded separately in the books

What is a cash discount?

A cash discount (also called a settlement discount) is a small reduction offered to the customer if they pay their invoice early, before the deadline.

  • For example, an invoice might say: "2% cash discount if paid within 10 days"
  • The full amount (before the cash discount) is first recorded in the books
  • If the customer pays early and claims the cash discount, the discount amount is then also recorded

How to complete a pro-forma invoice

A pro-forma document is a pre-made template with some information already filled in and some blank spaces for you to complete. In an exam, you may be asked to fill in the missing values on an invoice.

Step-by-step worked example:

Imagine an incomplete invoice shows the following:

QtyDescriptionUnit PriceAmount
50FlashcardsUSD 4???
???WorkbooksUSD 20???
SubtotalUSD 500
5% trade discount???
Total???

How to solve this:

Step 1: Calculate the amount for flashcards: 50 × USD 4 = USD 200

Step 2: Find the amount for workbooks: USD 500 − USD 200 = USD 300

Step 3: Find the quantity of workbooks: USD 300 ÷ USD 20 = 15 workbooks

Step 4: Calculate the trade discount: 5% × USD 500 = USD 25

Step 5: Calculate the total: USD 500 − USD 25 = USD 475

The key skill here is working with percentages and understanding that the subtotal comes before the discount is applied.
