What if an invoice contains calculation errors, e.g., the total amount due is incorrect?
Calculation errors, such as an incorrect sum in the "total amount due" field, improperly calculated VAT, or erroneous line item values, are not detected by the KSeF system. The system verifies only the technical compliance of the XML file with the electronic invoice schema, as well as whether the sender has the appropriate authorization.
If the arithmetic in the document content is incorrect, the file will still be accepted and receive a KSeF number, however the invoice will be issued with an error. Responsibility for substantive correctness, including calculations, lies with the issuer.
