Lesson Content/Board Summary
Business Documents
Meaning of Business Documents
Business documents are written records that provide evidence of business transactions. They serve as the primary source of information for recording entries in the books of accounts. These documents confirm that a transaction has occurred and provide details such as the date, parties involved, description of goods or services, and the amount.
Business Documents as Sources of Information
Business documents are essential sources of information for several reasons:
- Evidence of Transactions: They provide proof that a transaction actually took place.
- Basis for Recording: Accountants use these documents to record entries in journals and ledgers.
- Audit Trail: They create a trail that can be followed during an audit to verify the accuracy of financial statements.
- Legal Proof: In case of disputes, business documents can serve as legal evidence.
- Decision Making: They provide data for management to make informed business decisions.
Types of Business Documents and Their Uses
Invoice
An invoice is a commercial document issued by a seller to a buyer, indicating the products, quantities, and agreed prices for products or services the seller has provided to the buyer. It specifies the amount of money owed by the buyer to the seller.
Uses:
- To demand payment from a customer for goods sold on credit.
- To record sales on credit in the seller’s books.
- To record purchases on credit in the buyer’s books.
- As a source document for sales journal and purchases journal.
Debit Note
A debit note is a document issued by a seller to a buyer to inform the buyer that their account has been debited (increased) for a specific reason. It is often issued when the buyer has been undercharged on an invoice, or when goods returned by the buyer were not in good condition and a charge is being made for repairs.
Uses:
- To correct an undercharge on an invoice.
- To charge a customer for goods returned in a damaged condition.
- To inform the buyer of an increase in the amount owed.
Credit Note
A credit note is a document issued by a seller to a buyer to inform the buyer that their account has been credited (reduced) for a specific reason. It is often issued when goods are returned by the buyer, or when the buyer has been overcharged on an invoice.

- To acknowledge the return of goods by a customer.
- To correct an overcharge on an invoice.
- To inform the buyer of a reduction in the amount owed.

Uses:
- To keep a record of cheques issued for cash book entries.
- To track payments made from the bank account.
- As a reference for bank reconciliation.
- To provide evidence of payment.
