Short answer: invoices can’t be deleted, only cancelled: open the invoice, click Edit Invoice, then Cancel invoice and enter the reason.
1

Open the invoice

From Finances → Invoices, or the patient’s Invoices tab.
2

Click Edit Invoice

Then click Cancel invoice at the bottom of the drawer.
3

Enter the reason

The Reason is required. Click Cancel invoice to confirm.
4

Choose what to do with any money paid

Refund it to the patient, or Keep it as the patient’s balance for future invoices.
Cancel invoice button The treatments become un-invoiced, so you can invoice them again from the chart. Cancelled invoices are hidden from the list unless you choose Cancelled in the Status filter.
Cancelling can’t be undone, and balance (top-up) invoices can’t be cancelled. In Saudi Arabia, an invoice already reported to ZATCA can only be cancelled when Allow amending reported invoices is on.
Older Dentolize versions had Delete invoice. It was replaced by Cancel invoice so the record and its reason are kept. Old videos or messages that say “delete” now mean cancel.
Only need to change something on the invoice? You may not need to cancel it. See Edit an invoice.
