Credit notes vs refunds is one of those freelance money problems that looks small until it empties your checking account. Mistakes happen. Fix them on paper so tax season does not hurt.
Below is a practical US-focused walkthrough: what to do, what to put on the invoice, and what usually goes wrong.
The goal is simple: clear paperwork, fewer surprises, and money that arrives closer to the date on the PDF.
Credit note: reduces what a client owes; often applied to future invoices.
Refund: sends money back.
Numbering: use a clear credit sequence.
Reference: original invoice number always.
Books: never delete the original invoice.

Quick answer
If you overbilled or canceled part of a job after invoicing, issue a credit note referencing the original invoice. If they already paid, refund or apply credit — say which.
Do not edit history by deleting invoices. Auditors hate vanishing numbers.
Why this matters for freelancers
State the reason briefly: duplicate charge, unused hours, quality adjustment, etc.
Treat this as part of your billing system, not a one-off favor.
How to do it step by step
Example: Invoice 2026-0200 $2,000; Credit 2026-C018 -$400 unused hours; net $1,600.
If you refund via PayPal/Stripe, still issue a document for your records.
Keep credits in the same folder structure as invoices.
What to put on the invoice
Use clear line items, a unique invoice number, an explicit due date, and payment instructions. If a PO exists, put it on the PDF and in the email subject.

Common mistakes
Deleting invoices.
Credits with no original reference.
Verbal-only adjustments.
Mixing credit and new work on one confusing PDF without totals.
Fix the process once so you are not reinventing it under stress.
Credit note numbering
Use a prefix such as C-2026-014 so credits never collide with invoice 2026-014.
Your annual invoice log should list credits beside the invoices they adjust.
Bottom line
Document adjustments. Do not rewrite history.
Clear credits keep clients and accountants calm.
FAQ
Credit or refund?
Credit if they will buy again soon; refund if they want money back now.
Need client approval?
For disputed amounts, yes — get it in writing.
Sales tax on credits?
Often reverse the tax you charged — confirm with your advisor.
Negative-line next invoice instead?
Sometimes; a formal credit note is clearer.
Partial refund fees?
Processor fees may not return; decide who eats them in policy.
Number gaps OK?
Do not reuse numbers; gaps from voids should be explained in your log.
