Debit note generator: add charges to an invoice with a debit note PDF

A debit note tells a customer that they owe more than the invoice you already sent. Freight that was billed late, extra units shipped, a price rise both sides agreed in writing or an invoice that undercharged by mistake are the usual reasons. Instead of cancelling the first invoice, you issue a debit note that names it, explains the change and adds the extra amount with its tax. This generator builds that note in your browser with your logo, the original invoice number and date, the reason and any tax name and rate.

Quick answer

To make a debit note, enter your business and the customer, the number and date of the invoice you are adding to and the reason, then list each extra charge with its quantity, price and tax rate. Download it as a PDF in English, Arabic or both. The note shows the amount added before tax, the tax and the total added.

When to issue a debit note

Use a debit note when the amount on an invoice you already issued was too low. It keeps the first invoice intact, so both of you can still match it to the order and the delivery, and it leaves a clear record of why the total changed.

  • Freight, insurance or handling charged after the goods left
  • More units delivered than the invoice shows
  • A price increase agreed in writing after invoicing
  • A pricing or calculation error that undercharged the customer
  • Late-payment interest, where your contract allows it

Debit note or credit note?

The two notes are mirror images. A credit note reduces what the customer owes, for returns, discounts or overcharges; this site has a separate credit note generator for that. A debit note increases what the customer owes. Buyers also use the term for a note they send to a supplier when returning goods, asking the supplier to credit them; if that is your case, describe it clearly in the reason field so nobody reads it as a new charge.

Tax on a debit note

Tax rules on debit notes differ by country. India's GST law, for example, expects a supplier to issue a debit note when the taxable value of a supply goes up, while other tax systems ask for a new or corrected tax invoice instead. This generator does not decide that for you: it prints the tax name and rate you choose. Before relying on a debit note for tax, check what your tax authority or accountant expects, and keep the note with the original invoice.

Frequently asked questions

What should a debit note include?

Your business and the customer, a unique debit note number and date, the number and date of the original invoice, the reason, each extra charge with its price, the tax and the total added.

Who issues a debit note, the seller or the buyer?

Usually the seller, to charge more than the original invoice. Some buyers also send a debit note to a supplier when they return goods; the reason line should make clear which one it is.

Can one debit note cover several invoices?

It is clearer to issue one debit note per invoice, because each note names a single original invoice and your customer can match it in their books.

Does a debit note replace the original invoice?

No. The original invoice stays valid. The debit note only adds to it, and the customer pays both.

Is a UAE tax debit note an official document type?

The UAE VAT rules spell out tax credit notes but not a tax debit note. Ask your tax adviser how to bill an increase before you rely on a debit note.
