Free Debit Note Template (PDF, Word & Excel)
A debit note tells a customer their balance just went up, and exactly why — the mirror image of a credit note. Sellers issue one when an invoice undercharged the customer, or when extra costs both sides agreed to turned up after the invoice went out; buyers sometimes issue one too, when returning goods to a supplier. This page serves the first case: this free debit note template gives a seller a clean, dated document that references the original invoice, lists each additional charge with its reason, and states the new balance due. Download it below as PDF, Word or Excel. No sign-up needed; the files are yours to edit and reuse.

Debit Note Template (PDF / Word / Excel)
**Debit note template (PDF, Word, Excel).** All three files share the same debit note format: your business details, the customer's details, a debit note number and date, a reference line for the original invoice being corrected, then a line table — description of each additional charge, its reason, and its amount — followed by the total additional amount due and the new balance. The PDF is fixed-layout for quick fill-and-print. The Word version edits like any document: swap the logo, retype the lines, print. The Excel version has live line and total formulas, and the tax cell is blank for hand-entry — type an amount if one applies, or leave it at zero. None of the files ask for an email address.
What goes on a debit note
A debit note stands or falls on being traceable — every field below exists so the customer can tie the extra charge back to something they already agreed to.
- Debit note number and date. Give the note its own number in its own sequence (DN-0001, DN-0002…) and date it the day you issue it, not the date of the original invoice.
- Reference to the original invoice. The single most important line on the document: the invoice number this note corrects, and ideally its date. A debit note that doesn't name the invoice it corrects is just a mystery bill.
- Customer details. The same name and billing address as the original invoice, so accounts payable can match the two documents without a phone call.
- Reason for the debit, line by line. One line per charge, each with a plain-language reason — "freight omitted from INV-0913", not "adjustment". If the customer's bookkeeper can approve it without emailing you, the line is written well.
- Amount per line. The additional amount for each line, not the corrected total of the original invoice.
- Total additional amount due. The sum of the lines — the only new money this document asks for.
- Tax, if any. A single blank cell. Enter the tax amount that applies to the additional charges, or leave it at zero; the template never assumes a rate.
- New balance and payment terms. The customer's balance after this note, and when the additional amount is due — same terms as the original invoice unless you both agreed otherwise.
- Issued by, with signature. Who at your business issued the note, with a signature or printed name. Corrections carry more weight when someone owns them.
A filled-in debit note, line by line
The fastest way to understand a debit note is to watch one fix a real undercharge. Here, invoice INV-0913 billed a customer $2,400.00 for a machinery order — but the agreed freight charge of $180.00 never made it onto the invoice. Rather than reissue the invoice, the seller issues debit note DN-0914:
Debit Note DN-0914 · Date: July 30 · Reference: Invoice INV-0913, dated July 21
| Description | Reason | Amount |
|---|---|---|
| Freight — palletized delivery, dock to dock | Omitted from invoice INV-0913 | $180.00 |
| Total additional amount due | $180.00 | |
| Tax | $0.00 | |
| New balance on account | ($2,400.00 + $180.00) | $2,580.00 |
Billed to: Kessler Fabrication
Every number here traces back to a document the customer already has: they were invoiced $2,400.00, the freight was agreed but missed, and $2,400.00 plus $180.00 makes the new balance of $2,580.00. The line the whole note leans on is the reference line. "Omitted from invoice INV-0913" turns an unexpected charge into a correction of a known bill — the customer's bookkeeper pulls INV-0913, sees no freight line, checks the quote or contract that promised delivery, and approves. Strip that reference out and the identical $180.00 becomes a mystery bill that sits in a queue while someone emails you to ask what it's for. If you only get one field right on a debit note, make it that one.
Debit note or a new invoice?
Correct an existing bill with a debit note; bill new work with a new invoice. That's the whole rule. If the money you're asking for belongs to a transaction you already invoiced — an undercharge, a missed freight line, a cost overrun both sides signed off on after the invoice went out — a debit note keeps the paper trail intact: the original invoice stays untouched in both sets of books, and the note documents exactly what changed and why. If the money is for something new — another order, an added project, out-of-scope work — issue a new invoice, because there is no existing bill to correct and a debit note would have nothing to reference.
That reference is also the practical test when you're unsure. Ask: which invoice number would this note point to? If a specific invoice comes to mind and the charge should have been on it, write the debit note and put that number on the reference line. If you can't name one, the charge isn't a correction — it's new billing, and it deserves its own invoice with its own number.
Frequently asked questions
What is the difference between a debit note and an invoice?
An invoice bills a transaction; a debit note corrects one that was already billed. The invoice is the original request for payment, created when goods or services are delivered. The debit note comes later, references that invoice by number, and asks only for the additional amount — it never restates the whole bill.
What is the difference between a debit note and a credit note?
They move the customer's balance in opposite directions: a debit note increases what the customer owes, a credit note reduces it. This page covers the debit side; for the credit direction — refunds, overcharges, returns you owe money back for — see our credit invoice guide.
Does the customer have to accept a debit note?
In practice, a debit note gets paid when it corrects something the customer already agreed to — a price in the contract, a cost both sides approved — and gets disputed when it doesn't. It is a correction document, not a way to add new charges unilaterally, so tie every line to an existing agreement and confirm significant corrections with the customer before the note lands. What a debit note can enforce ultimately depends on your contract and local rules.
Can I cancel a debit note I issued by mistake?
Don't delete it — issue a credit note for the same amount, referencing the debit note. That reverses the charge while keeping both documents in the record, so your sequence stays unbroken and both sets of books show what happened. Deleting issued documents leaves a numbering gap that looks worse than the mistake did.
How should I number debit notes?
Give them their own sequence with their own prefix — DN-0001, DN-0002 — separate from your invoice numbers. Mixing corrections into the invoice sequence makes both harder to audit; a separate DN- series means anyone scanning your records can see at a glance how many corrections you issue and find any one of them instantly.
