Invoicing and documents
Debit note
A debit note is a commercial document issued by a buyer to request a credit, or by a seller to increase the amount owed on an existing invoice.
What is Debit note?
A debit note acts as a formal request or notification regarding an adjustment to a financial balance. You will encounter debit notes in two common scenarios. First, as a buyer, you might issue a debit note to a supplier when returning damaged goods, effectively requesting a credit note in response. Second, as a seller, you might issue a debit note to a customer if you accidentally undercharged them on an original invoice, thereby increasing their payable balance. It is crucial to distinguish this from a credit note. A credit note decreases the amount a buyer owes, whereas a debit note increases the amount owed or requests a reduction in your own accounts payable. By using debit notes, you maintain an accurate audit trail without altering finalised tax invoices, ensuring your accounting records remain compliant and transparent.
How Debit note works
The process begins when an error or return is identified after an invoice has already been issued and recorded. If you are the buyer returning defective inventory, you generate a debit note detailing the items, their value and the original invoice number. You send this document to your supplier. The supplier reviews the request and, upon approval, issues a corresponding credit note to formally reduce your payable balance. Alternatively, if you are the seller who underbilled a client, you issue the debit note directly to the buyer. This document notifies them of the additional charge. The buyer then updates their accounts payable ledger to reflect the higher amount owed. Finally, the outstanding balance is settled during the next payment cycle according to the updated ledger.
- Identify an undercharge or a need to return damaged goods to a supplier.
- Draft the debit note referencing the original tax invoice and the adjustment reason.
- Send the document to the other party to notify them of the balance change.
- Wait for the supplier to issue a credit note if you are the buyer.
- Update your general ledger to reflect the newly adjusted accounts payable or receivable balance.
Worked example
Gulf Trading Supplies receives an invoice for 100 office chairs at $50 each, totaling $5,000. Upon delivery, they discover that 10 chairs are broken. Gulf Trading Supplies issues a debit note to the manufacturer for the damaged goods. The calculation is 10 chairs multiplied by $50, which equals $500. They send this $500 debit note to the manufacturer to request an adjustment. The manufacturer accepts the return and issues a $500 credit note. Gulf Trading Supplies then pays the revised balance of $4,500 ($5,000 minus $500) to settle the account.
Why it matters for your business
Handling debit notes correctly is essential for accurate financial reporting and inventory management. If you fail to issue a debit note for returned goods, you risk overpaying your suppliers and losing valuable working capital. Conversely, if you forget to issue a debit note when you undercharge a customer, your business absorbs the financial loss. Proper documentation also protects you during tax audits by providing a clear paper trail for every adjustment. Paper & Pen creates invoices, quotations and receipts, making it simple to track these adjustments alongside your standard billing documents. Maintaining strict control over debit notes ensures your cash flow remains predictable and your supplier relationships stay professional.
