> Sent an invoice by mistake? Void it to cancel it and stop it counting as money owed, while keeping it on your records.

Everyone sends the wrong invoice now and then: the wrong client, a duplicate, or the wrong amount. You've got two ways out — **void** it or **delete** it — and they're not the same thing.

## What voiding does

Voiding cancels the invoice. It stays on your records, nothing is deleted, but it stops counting as money owed, so it drops out of your outstanding and overdue totals and Mucka stops chasing it. Think of it as the bookkeeper's way of cancelling: you don't shred the paperwork, you mark it void.

## Void or delete?

- **Void** cancels the invoice but keeps it. It stays in your records with a grey **Cancelled** badge, so there's a trail showing it was raised and cancelled. This is the safe one, and it's what your accountant would want.
- **Delete** removes it completely. The invoice, its lines and its history go, and there's nothing left to show it existed. Any copy or payment link your customer has stops working.

If your customer has seen the invoice, void it. If it never should have existed and nobody's seen it, delete it. See [Delete an invoice](/help/invoices/delete-an-invoice) for when deleting is allowed.

## What you can and can't void

- **Draft invoices:** there's nothing to void — nobody has seen it. Just delete the draft.
- **Sent, overdue or part-paid invoices:** these can be voided.
- **Paid invoices:** these can't be voided. A paid invoice is settled, so reversing it is a credit note or refund job, not a void. Get in touch if you need to handle one of those.

For a part-paid invoice, voiding writes off the unpaid remainder. Any payment you already recorded stays on record as money received.

## How to void one

1. Open the invoice from the [**Invoices**](/invoices) page.
2. Tap **Void invoice**.
3. You'll get a confirm step. Add a short reason if you like (handy for your own records), then confirm.

The invoice then shows a grey **Cancelled** badge, and it drops out of sight: it's hidden from the invoices list, it won't come back in a search, and it comes off the job it was raised against. Nothing is lost — use the **Show cancelled** toggle on the [**Invoices**](/invoices) page to bring cancelled ones back into view whenever you need them.

## Ask Mucka

You can ask Mucka to do it in app chat, on voice, on WhatsApp or over the phone:

> *"Void invoice INV-0123, it was a duplicate."*

Because voiding affects your books, Mucka never does it on its own. In the app it shows you a card with a **Void** button to tap, and on a call it gets it ready for you to approve in the app. One tap from you and it's done.

## Good to know

- **It can't be undone.** A voided invoice stays cancelled. If you need it back, raise a fresh one.
- **It's logged.** Who voided it and when is recorded in your activity log under [**Settings**](/settings), so there's always a trail.
