About Accountant credit notes

Accountants issue credit notes when an engagement is terminated before year-end accounts are completed and a portion of the fixed fee needs to be returned, when a tax return service is cancelled before filing, or when a billing error results in a client being charged the wrong tier of service. Issuing a credit note in these situations is both professional practice and a requirement for accurate bookkeeping.

The credit note references the client's engagement reference and the original invoice, lists each adjustment with a clear description, and provides a formal document for both parties' financial records.

When to issue a credit note

Issue a credit note when a small business client terminates their monthly bookkeeping retainer mid-year after paying a block of months upfront. Use one when a personal tax return service is cancelled after onboarding but before any work begins. It also applies when a client is billed for a full accounts preparation package but the scope is reduced because they are no longer trading.

Frequently asked questions

A client cancelled their bookkeeping retainer with months prepaid. How do I calculate the credit?

Multiply the monthly retainer fee by the number of unused months. If the month in progress is partially complete, consider crediting a prorated amount based on the work done so far. Document the calculation on the credit note and reference the original invoice and retainer agreement.

Do I need to issue a credit note for a billing error I made on my own firm's invoice?

Yes. Even though the error was yours, a credit note is the correct way to formally correct the record once the invoice has been sent or paid. Do not edit or void the original invoice in your system if it has already been issued. The credit note corrects the position while keeping both documents in the audit trail.

Should the credit note be signed or approved before I send it to a client?

That depends on your firm's internal process. Sole practitioners can issue credit notes without a separate approval step, but firms should have a second sign-off to prevent unauthorised credits. Whatever your process, the issued credit note should be retained in the client file alongside the original invoice.
