Charge for extra units delivered — the difference, referenced, in a professional PDF.
100% freeNo signupNo watermarkInstant PDF download
A quantity-variance debit note charges for units delivered above what the original invoice billed — an over-delivery the customer kept, or a count corrected upward. It bills just the extra quantity against the original invoice.
This template opens with itemised lines. Reference the invoice, charge the extra units at their price, note the variance, and download a PDF debit note.
Note: Charges over-delivered units · references the original invoice.
Issue a debit note referencing the invoice for the extra units at their price, with tax, showing the invoiced vs delivered quantity. It bills the variance cleanly.
If the customer agrees to keep and pay for the extra, a debit note bills it; if they return it, use a return process instead. Confirm which before charging.

A debit note increases the amount owed on an invoice already issued — for an undercharge, additional charges or interest. A credit note does the opposite: it reduces or cancels what is owed. Buyers also raise debit notes to notify a supplier of a return or a claim.
A debit note increases what a customer owes on an invoice already sent. The Invoices Tracker keeps your invoices, debit notes and what each client still owes together — so your books always reconcile.
