A credit note is the document a business sends when it needs to reduce or cancel part or all of an invoice it already issued. Freelancers, contractors, shops, and small agencies send them for billing errors, returns, cancelled work, partial refunds, and goodwill adjustments. Each one ties back to an original invoice and shows exactly what is being credited and why.

A credit note is not a service you sell, so there is no price for the document itself. What you set is the amount of each adjustment. Most small businesses follow a written policy: overbilled hours or duplicate charges are credited at 100% of the original rate, returned goods are credited at the sale price minus a restocking fee, and cancelled work is credited minus time already spent or a retained portion of the deposit. Goodwill credits for late or unsatisfactory work are usually a percentage of the affected line item, not the whole invoice. Credit the tax in proportion to the amount credited, and decide up front whether the credit is refunded to the original payment method or held as a balance against the next invoice.
| Service | Priced | Typical range |
|---|---|---|
| Credit for overbilled or duplicated hours | per hour at original rate | $50-150 |
| Restocking fee kept on returned goods | percent of item price | 10-25% |
| Retained portion of deposit on cancelled work | percent of deposit | 10-25% |
| Partial credit for incomplete or missed deliverable | percent of line item | 10-50% |
| Goodwill credit for late delivery | percent of invoice | 5-15% |
| Early payment discount applied after payment | percent of invoice | 1-2% |
| Card processing fee withheld from refund | percent of refunded amount | 0-3.5% |

Notes: Credit note issued against Invoice #1042 dated March 3. Net credit of $477.80 will be applied to your next invoice, or refunded to the original payment method within 10 business days if you reply to request it. Sales tax has been adjusted in proportion to the credited items.
The credit note has to point to the exact invoice it adjusts so both sides can reconcile their books.
A separate numbering sequence, such as CN-0007, keeps credits from being confused with invoices and gives you an audit trail.
Clients and accountants need to see which items, hours, or charges are being reduced, not just a lump sum.
A short reason such as billing error, return, or cancellation prevents questions and supports your records if you are audited.
If you charged sales tax, the tax on the credited amount should be reduced too. Check your state rules on how to report it.
State whether it is a refund, an applied balance, or an offset against an unpaid invoice, and give the timeframe.
Showing the new amount owed after the credit avoids the client paying the old total by mistake.
A credit note either reduces what the client still owes or creates money owed back to them. If the original invoice is unpaid, apply the credit and send the client the revised balance with the usual due date. If it was already paid, offer a refund to the original payment method, typically within 5 to 10 business days, or a credit balance applied to the next invoice. Card refunds often do not return the processing fee to you, so mention that in your refund policy. Do not charge late fees on any portion of an invoice that has been credited, and make sure late fees already added are reversed if the underlying charge was an error.
Once an invoice has gone out, issue a credit note instead of changing it. This keeps your numbering clean and leaves a clear record for your accountant and for the client.
Put restocking fees, cancellation terms, and deposit rules in your contract or quote. A credit note that follows terms the client already agreed to rarely gets disputed.
If the original invoice included sales tax, reduce it in proportion. Leaving the tax in place means the client overpays and you may over-report tax collected.
Clients get confused when they receive a credit and still see the old invoice total. State the new amount due, or the refund amount, in the same message.
Reviewing credits every quarter shows patterns such as repeated billing errors or scope disputes, which usually point to a problem in your quoting or time tracking.
A credit note is the document that records a reduction in what the client owes. A refund is the actual return of money. You can issue a credit note and settle it by refund, by applying it to a future invoice, or by offsetting it against another unpaid invoice.
If the invoice has already been sent, issuing a credit note is the safer practice. Some accounting setups let you void an invoice that was never sent or paid, but check with your accountant before voiding anything the client has seen.
In many states, yes. If you credit a taxable item, the tax collected on it is also credited or refunded, and you adjust it on your next sales tax return. Rules differ by state, so confirm with your state's revenue department or an accountant.
Yes. Partial credits are common for a single overbilled line, a damaged item, or a discount. List only the amounts being reduced and show the remaining balance on the original invoice.
Keep them with your invoices and other financial records. Many small businesses keep records for at least three to seven years, but the right period depends on your tax situation, so check with your accountant.
