How to Cancel or Void an Invoice
Mistakes happen: the wrong client, the wrong amount, a duplicate send. Learning how to cancel or void an invoice the clean way protects your records and the client's. Do not pretend the first PDF never existed if they already received it. This guide covers drafts you never sent, invoices you sent in error and the role of a credit note.
If You Never Sent It
A draft that only you have seen can be deleted or overwritten. On our home-page generator you can clear the form and start again. Do not reuse a number you already assigned to a sent invoice. If the number never left your desk, you can reuse it. If you are unsure, skip ahead to the next number. See invoice numbering.
If the Client Already Has the PDF
Tell them the invoice is cancelled and why, in writing. Then do one of the following, depending on local practice and whether they have booked the bill:
- Issue a credit note for the full amount, then send a new invoice with a new number.
- Mark the original as void in your records and send a corrected invoice, if they have not entered the first one yet and they agree.
Never silently change a sent PDF and hope nobody notices. Two files with the same number and different totals cause chaos.
Good to know: "Void" usually means the invoice should not be paid and should not count as income. "Cancel" is everyday language for the same idea. Your records should show the outcome clearly.
Update Your Tracking Sheet
Change the status to Void or Credited. Keep the PDF of the original and of the credit note. That trail matters if you are asked about the gap later. Tracking unpaid invoices and tax-time records both assume you do not destroy history.
Correct the record in public, with the client, not by editing the past.
Watch out: Tax authorities may have rules about voiding invoices that already included tax. Confirm the method with a local professional.
Frequently Asked Questions
Can I reuse the old invoice number?
Not after the client has seen it. Issue a new number for the replacement bill.
What if they already paid the wrong invoice?
Refund or credit the difference and document both sides. Do not just send a new invoice for the extra without explaining the first payment.
Should I keep voided PDFs?
Yes. Keep them marked void so you can explain the sequence.
