An issued invoice cannot be changed and cannot be deleted. The books have to show the transaction — including the wrong one. There are three ways out, and they are different.
A cancellation, correction or reversal draft shows the tax note and the paper format of the original invoice — already in the draft, not only once issued. If your business has changed its tax status since then, the situation of the invoice it corrects still applies to that one document.
Which route you take
| Case | Route |
|---|---|
| The invoice is completely wrong — wrong recipient, wrong project, wrong amount. | Cancel |
| The invoice is right in principle, but the amount is too high. | Reduce |
| A quote or an order confirmation should go away. | Withdraw |
Canceling
Cancel creates a cancellation invoice as a draft. Review it and issue it — only then does the invoice change to Canceled. You have to send the cancellation invoice to the recipient — otherwise they know nothing about it and your invoice stays open in their books.
The reason for cancellation is internal and does not appear on the document. Enter it all the same: in a year’s time it is the only explanation there is.
The cancellation invoice takes over Our contact person from the original invoice — not from you as the person creating it. If that is no longer right, you change it on the draft as usual.
An issued cancellation invoice cannot be undone. You can still delete the draft before that.
With the tick box Issue the invoice again Zirko produces, in the same step, a new invoice with the same line items — the button is then called Cancel & issue again. That is the usual case: the mistake out, the correct invoice in.
Reducing
Reduce produces an invoice correction for the difference. You enter a reason — that is mandatory and is printed — and the reduced gross amount. Zirko shows the balance of unreduced, reduced and correction.
This route fits when one line item too many was in there, or the quantity was set too high, and the rest stays right.
Reducing is not possible with several VAT rates or several tax categories on one document. Then only canceling remains.
You undo a correction that was itself wrong with Reverse correction — a reversal document is produced.
Withdrawing
For quotes, cost estimates and order confirmations there is Withdraw. No correction document is produced. The document stays readable and keeps its number — the GoBD (the German rules for keeping digital books and records; in other countries the local equivalent applies) requires that too.
And if it is still a draft?
Then Delete document works — but only as long as no number has been assigned. The number is created when you finalize, and from then on the route is the one described above.
The case where you do not have to cancel anything
You sent a PDF where an e-invoice was required. Do not cancel. Submit the same invoice through the portal — it is correct in content, it is just in the wrong place. The route is under How the authority receives your invoice.
