The mirror of the credit note — formally increase what’s owed, or document a purchase return to your supplier.
“Debit note” means different things depending on who issues it. A seller issues a debit note to increase the amount a buyer owes after an invoice went out too low — an undercharge, a quantity correction, a contractual price escalation, or tax charged at the wrong rate. A buyer issues a debit note to a supplier when returning goods, formally debiting the supplier's account and requesting a credit note in response. Either way the structure is the same: reference the original invoice, itemise the adjustment, state the tax.
Don't reissue the invoice — supplement it. The debit note carries its own sequential number (DBN-001…), cites the original invoice in the reference field, and shows only the additional amount due, with tax computed on the supplement. Under GST, Section 34 requires a supplier to issue a debit note when the original tax invoice charged less than the actual taxable value or tax; the debit note is declared in your returns and increases your output liability for that period.
Returning goods without paperwork is how disputes start. A debit note tells your supplier exactly what is being returned, against which invoice, at what value — and signals the amount you expect credited. Itemise the returned goods with quantities and rates so the supplier's credit note matches yours line for line.
Same engine as the invoice: your branding, GST fields with automatic CGST/SGST/IGST split, HSN/SAC, multi-currency, amount-in-words, signature, and a separate numbering sequence per business profile.
Like every tool on this site, the debit note maker runs entirely in your browser. Clients, line items and history are stored on your device in IndexedDB — never uploaded, never seen by us, exportable as a single backup file, deletable any time. It also works completely offline once loaded, and the PDF never carries a watermark.
When an issued invoice understated the value or tax — undercharges, quantity corrections, price escalations. The debit note adds the difference without touching the original invoice.
On purchase returns: it documents goods sent back to the supplier and the amount the buyer expects credited, usually answered by the supplier’s credit note.
A supplier’s debit note increases output tax liability and is declared in the GST returns for the period. It must reference the original invoice; the GST fields here mirror the invoice exactly.
Yes — its own DBN sequence per business profile, keeping your invoice numbering untouched.
