What happens to canceled invoices?
When you cancel an invoice in Mallow, you may provide an optional "cancellation reason" message. Once cancelled, the public invoice link stops working. If you entered a reason, the client will see your message on the canceled invoice page; if you didn't, the client sees only the generic canceled message.
How to cancel an invoice
Go to Money → Dashboard. On mobile, tap the Pages pill in the bottom footer and select Money, then open the Dashboard tab.
Find the sent or overdue invoice you want to cancel.
Click the three-dot menu on that invoice row, then select Cancel invoice.
In the cancellation modal, enter an optional reason.
Click Cancel invoice to confirm. To close without canceling the invoice, click Go back.
What the client sees
The payment page displays a clear "Invoice Canceled" message with context about which invoice was canceled. The client will not be able to pay a canceled invoice through that link.
If you entered a cancellation reason, the page also shows a Reason for cancellation subheader with your message in italics. If you left the reason blank, the page shows only the generic canceled message.
What to do if your client asks about a canceled link
Confirm you intentionally canceled the invoice. If so, let the client know that the link is no longer valid and the invoice cannot be paid.
If you still need payment, create and send a new invoice. Canceled invoices cannot be reactivated — you need to create a fresh invoice with a new link.
How canceled links differ from payment failures
A canceled invoice link is not the same as a failed payment. If a client tried to pay and the transaction didn't go through, that's a separate issue covered in Recover failed or incomplete payments. A canceled link means the invoice itself was voided before any payment could be attempted.
