fakturownia-invoice-ksef-correction-to-zero

To issue a KSeF correction to zero in Fakturownia, inspect the original invoice to obtain its gov_id, then create a correction invoice with gov_corrected_invoice_number set to that KSeF number and negative position amounts.

A correction-to-zero invoice in KSeF e-invoicing is a correction invoice that fully nullifies an original invoice by referencing its gov_corrected_invoice_number and using negative position amounts to zero out the totals.

Before creating a KSeF correction invoice, you must inspect the original invoice's id, number, gov_id, and gov_status fields to ensure you can accurately reference the corrected KSeF number in the payload.

Fakturownia correction-to-zero logic does not require a dedicated CLI verb; instead, the correction payload with gov_corrected_invoice_number and negative amounts is handled through standard invoice get and create operations.

You compose a KSeF correction payload by setting gov_corrected_invoice_number to the original invoice's KSeF number and including correction line items with negative position amounts to reverse the original billing values.
