A debtor is a person or business that owes money to someone else, whether under a loan, a credit account or an unpaid invoice.

Also known as: trade debtor, borrower, account debtor

Key points

  • In business accounting your debtors are the customers who owe you money, shown on the balance sheet as receivables.
  • Slow-paying debtors are a common cause of cashflow pressure, which is why invoice terms and follow-up matter.
  • You can turn unpaid invoices into working capital using factoring or invoice discounting.
  • If a debtor never pays, the amount is eventually written off as a bad debt.
  • When you borrow, you are the debtor: missed repayments put you in arrears and can show on your credit file.

Frequently asked questions

What is the difference between a debtor and a creditor?

The debtor owes the money and the creditor is owed it. Most businesses are both at the same time: a creditor to customers who have not paid, and a debtor to suppliers, lenders and the ATO. Which label applies depends entirely on which side of the invoice you are on.

What are debtor days?

Debtor days measure how long, on average, customers take to pay. You divide the debtor balance by annual sales and multiply by 365. A rising number means money is being collected more slowly, which squeezes cashflow even when sales look healthy.

What happens if a debtor does not pay?

The creditor usually starts with reminders and a payment plan, then a formal demand, then a collection agency or court action. Company debts may attract a statutory demand. If recovery fails, the creditor writes the amount off as a bad debt and may be able to claim back the GST.

Is a debtor an asset?

Yes. Amounts owed to your business are current assets on the balance sheet, listed as trade receivables. They are not cash yet, though, which is why a business can show a profit and still run out of money. Lenders often discount older balances when assessing the ledger.

Can I borrow against my debtors?

Yes, through invoice finance. Factoring sells the invoices to a financier who also collects them, while invoice discounting advances funds against the ledger and leaves collection with you. Both release cash sooner, and both cost money, so compare the fees against the benefit of being paid earlier.
