- An erroneous invoice made before submission to KSeF can be canceled if it has not entered legal circulation.
- A generated XML file with errors that was neither sent to KSeF nor delivered to the buyer may be deleted or canceled.
- Once an invoice is accepted by KSeF or sent to the client, it is considered legally circulated.
- After that point, it can only be corrected by issuing a corrective invoice.
