Everyone sends the wrong invoice now and then: the wrong client, a duplicate, or the wrong amount. You can't delete a sent invoice (that protects your records), but you can void it.
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.
What you can and can't void
- Draft invoices: there's nothing to void. 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
- Open the invoice from the Invoices page.
- Tap Void invoice.
- 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. Cancelled invoices are hidden from the list by default. Use the Show cancelled toggle to bring them back into view.
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, so there's always a trail.
