A credit note template

The one field that makes a credit note useful, and the one that makes it useless.

Last updated 20 August 2026

A credit note template is short, and one field on it does most of the work: the original invoice number. Without it, neither your accounts nor the customer’s can match the two documents, and the credit floats unreconciled.

Fix these once

Leave these blank

The customer, the credit note number, the date, the reason, the lines and the amounts. And the original invoice number, obviously, but leave the labelled row in place so it is a blank someone notices.

A template to copy

CREDIT NOTE                    No. CN-____
                               Date: ____

Issued to
[left blank]

Against invoice   ____
Reason            ____

Description                    Qty    Rate      Amount
____________________________   ___    ______    ______

                               Subtotal        ______
                               Tax  __%        ______
                               Total credited  ______

This credit note reduces the amount owed on the invoice above.

Keep the figures positive

A credit note for 4,200 is clearer than an invoice for minus 4,200. The title does the work of saying it reduces what is owed.

Match the original invoice’s rates exactly. If you charged 1,400 per unit and three came back, credit three at 1,400. Rounding the credit to a convenient number is how the two documents stop reconciling.

Credit only the affected lines

A partial credit is normal. List the lines being credited and only the quantities being returned. The rest of the original invoice stands.

Do not restate the whole invoice with a smaller total. That produces two documents claiming to be the whole picture.

Variants

Return. Quantity and rate columns, a reason line, and a note of who collected the goods.

Price correction. One line, no quantity, describing the correction: “Rate corrected from 1,650 to 1,400 on 12 units, invoice INV-2026-0038.”

Goodwill. A single line and an amount, with the reason stated plainly. These are worth wording carefully, since they are the ones queried later.

Each is a saved file, written to your own disk with Save as file.

Tax

If you charged tax on the original, credit it proportionally. A credit note that reverses the net but not the tax leaves both sides with a tax position that does not reconcile.

Where your jurisdiction requires specific wording on a tax credit note, put it in the template rather than remembering it each time.

Numbering

Its own sequence, CN-0001 upward. Never fold credit notes into the invoice sequence, since that leaves gaps in the invoice numbers that look like missing sales.

See numbering your documents.
