Only the difference

Put the additional charge on the note, never the whole invoice again. A debit note carrying the full amount creates a second debt for the same supply, which is the most expensive mistake there is in this area.

About the Invoice Debit Note Generator

A debit note increases what is owed against an invoice already issued. It is the right document when you under-billed, when work was done beyond the original scope, when freight was left off, or when a tax rate was applied wrongly and the correction goes upwards.

The rules are the mirror of a credit note. Only the difference goes on it, never the whole invoice again — putting the full amount on a debit note creates a second debt for the same supply, which is the single most expensive mistake in this area. It needs its own sequential reference and a reference to the original. It carries tax on the addition at the rate the original supply attracted. And it needs a notice saying it is an addition rather than a duplicate, because without one it gets either paid twice or ignored entirely.

This produces one with all of that, in either direction: as a supplier charging more, or as a buyer raising a debit note against a supplier for a short delivery or an agreed rebate, which is how it works in retail.

Frequently asked questions

When the charge relates to a supply already invoiced — an under-billing, an omitted charge or a tax correction. Genuinely new work is a new invoice, not a debit note against an old one.
