build_certificate_qr_templateAbout
Poland e-Invoice QR and Readiness works with the National e-Invoice System (KSeF) verification codes and start dates. compute_invoice_hash gives the SHA-256 of the exact invoice XML bytes in Base64URL, as the QR link needs it. build_invoice_qr_url assembles the type I verification link (seller NIP, issue date, hash) for the production, demo or test host. build_certificate_qr_template assembles the type II offline-invoice link and the exact text that the owner's offline certificate must sign, with the signature parameters the documentation lists; it never signs anything. qr_label_text gives the text printed under each code. validate_nip checks the format and checksum of a Polish NIP. ksef_start_phase and days_until_ksef_deadline apply the published phase-in dates (1 February 2026, 1 April 2026, 1 January 2027) to the business's 2024 sales and monthly invoiced sales for a chosen date, and show whether the 2026 no-penalty period still runs. ksef_offline_modes_guide explains offline24, unavailability and emergency modes, their sending deadlines and which QR codes each carries. Everything is computed locally: no invoice is submitted, stored or signed, and no KSeF credentials are used. Independent tool; not affiliated with the Ministry of Finance or the KSeF operator. General information, not tax advice.
