A debtor is a person or business that owes money to another business, and a creditor is a person or business to whom a business owes money. Both arise when goods or services are bought or sold on credit, with payment made at a later date.
Behavioural objectives
By the end of the lesson, students should be able to:
- define debtors and creditors;
- state the other names for debtors and creditors;
- explain how a debt arises when goods or services are sold or bought on credit;
- describe how a business determines its debtors and its creditors;
- state why a business should keep track of its debtors and creditors.
What is a credit transaction?
A credit transaction is a sale or purchase in which payment is made at a later date.
- Credit sale: the business hands over goods or services now and the customer pays later.
- Credit purchase: the business receives goods or services now and pays the supplier later.
- Cash transaction: payment is made at the time of the sale or purchase, so no debt is created.
What is a debtor?
A debtor is an individual or company that owes money to a business, and is also called an account receivable.
- How it arises: the business sells goods or services to a customer on credit.
- Other name: accounts receivable, because the business expects to receive the money.
- Example: a customer collects ₦50,000 worth of goods from Bola Stores and promises to pay next month. The customer is a debtor of Bola Stores.
- Position in the books: money owed by debtors is an asset of the business.
What is a creditor?
A creditor is an individual or company that a business owes money to, and is also called an account payable.
- How it arises: the business buys goods or services on credit from a supplier.
- Other name: accounts payable, because the business must pay the money.
- Example: Bola Stores buys ₦200,000 worth of goods from a wholesaler and will pay in 30 days. The wholesaler is a creditor of Bola Stores.
- Position in the books: money owed to creditors is a liability of the business.
What is the difference between a debtor and a creditor?
A debtor owes the business, while the business owes a creditor. The table compares them.
| Point | Debtor | Creditor |
|---|---|---|
| Meaning | Owes money to the business | Is owed money by the business |
| Other name | Account receivable | Account payable |
| Arises from | Credit sales | Credit purchases |
| Who the person is | Customer | Supplier |
| Effect on the business | Asset | Liability |
| Cash movement later | Cash comes in | Cash goes out |
How are debtors determined?
A business determines its debtors by tracking all credit sales that have not yet been paid for.
- The business sells goods or services to a customer on credit.
- An invoice is prepared and sent to the customer.
- The sale is recorded in the customer’s account in the accounting system.
- The account is updated regularly as payments are received.
- Any customer whose account still shows an unpaid balance is a debtor.
How are creditors determined?
A business determines its creditors by tracking all credit purchases that it has not yet paid for.
- The business buys goods or services from a supplier on credit.
- The supplier sends an invoice (a bill) to the business.
- The purchase is recorded in the supplier’s account in the accounting system.
- The account is updated regularly as payments are made.
- Any supplier whose account still shows an unpaid balance is a creditor.
How are debtors and creditors recorded?
Debtors and creditors are recorded in personal accounts, one account for each person or business.
- Credit sale: debit the debtor’s account and credit the sales account.
- Debtor pays: debit the cash or bank account and credit the debtor’s account.
- Credit purchase: debit the purchases account and credit the creditor’s account.
- Business pays creditor: debit the creditor’s account and credit the cash or bank account.
- Debtors’ ledger: the book that holds the accounts of customers (also called the sales ledger).
- Creditors’ ledger: the book that holds the accounts of suppliers (also called the purchases ledger).
Why should a business keep track of debtors and creditors?
A business keeps track of debtors and creditors to maintain a healthy cash flow.
- Follow up on overdue payments: the business can remind debtors who have not paid on time.
- Manage cash flow: the business knows how much cash to expect and how much it must pay out.
- Pay suppliers on time: this keeps the goodwill of creditors and protects the business’s name.
- Avoid disputes: clear records settle arguments about amounts owed.
- Reduce bad debts: early follow-up lowers the chance that a debtor never pays.
- Review reports regularly: the accounts receivable and accounts payable reports show who owes what.
Evaluation
- Define a debtor and a creditor.
- What other name is given to debtors? What other name is given to creditors?
- How does a business come to have a debtor?
- How does a business determine who its creditors are?
- Why should a business review its accounts receivable and accounts payable reports regularly?
