fakturownia-invoice-ksef-correction-to-zero

What problem does it solve?

Provides clear, actionable guidance for correcting invoices issued via KSeF in Fakturownia where the correction process requires referencing the KSeF number of the corrected invoice and sometimes producing a correction-to-zero.

Core Features & Use Cases

• Inspect existing invoices to retrieve id, number, gov_id, and gov_status before issuing a correction.
• Create KSeF correction invoices that include the gov_corrected_invoice_number field and correction line items with negative amounts for correction-to-zero scenarios.
• Operator guidance on keeping correction-to-zero logic in payloads and operator instructions rather than adding a dedicated CLI verb.

Quick Start

Inspect the original invoice with invoice get to obtain its id and gov_id, then create a correction invoice that sets gov_corrected_invoice_number to the original KSeF number and includes negative position amounts.
