What Is A Debit Note In Singapore?

A debit note is a commercial document issued by a seller to a buyer, notifying the buyer of an additional amount payable on a previous invoice. It essentially serves as a supplementary invoice. Unlike a credit note, which reduces the buyer’s payable amount, a debit note increases it.

Key Characteristics:

  1. Always linked to an original invoice.
  2. Used to adjust errors or undercharges.
  3. Provides transparency and proper documentation.
  4. May or may not include GST, depending on the transaction type.

Why A Debit Note Is Issued

Businesses issue debit notes for several reasons. Common scenarios include:

  • Correcting Underbilling
    When an invoice mistakenly undercharges the buyer, a debit note is used to add the missing amount.
  • Adjusting For Additional Charges
    If additional costs arise after the invoice was issued (e.g., extra freight or services), a debit note documents these charges.
  • Internal Billing
    For internal cost transfers within the same company structure, debit notes are often used, especially when GST is not involved.

    • Invoice total: S$50,000.
  2. Invoice Error
    • Company B mistakenly charged only S$40,000, underbilling Company A by S$10,000.
  3. Company B’s Action
    • Company B issues a debit note for S$10,000 to correct the underbilling.
