A document issued by a seller to increase the amount owed by a buyer, or by a buyer to formally request a credit from a seller for returns or overcharges.
A Debit Memo (or Debit Memorandum) increases the buyer's payable amount when issued by the seller (for additional charges, undercharging, or supplementary invoices), or reduces the seller's receivable when issued by the buyer (to notify of returns or request credit). Under GST, a Debit Note is issued when the taxable value or tax charged in the original invoice is less than the actual amount — this increases the seller's output tax liability. Common scenarios include: freight charges added after invoicing, price escalation clauses triggered, quantity revisions upward, and supplementary GST charges. Like credit memos, debit memos must reference the original invoice.
Original Invoice #601: 500 kg steel @ ₹80/kg = ₹40,000 + 18% GST = ₹47,200. Price revision clause triggered — new rate ₹85/kg. Debit Note #DN-044: 500 kg × ₹5 difference = ₹2,500 + GST ₹450 = ₹2,950. New total payable: ₹47,200 + ₹2,950 = ₹50,150.
