Invoicing compliant with VeriFactu: chained hash, AEAT QR code, gap-free numbering and immutability.
Invoicing is built to comply with RD 1007/2023 (VeriFactu). Each invoice generates an invoicing record chained by SHA-256 hash with the previous one, an AEAT tax verification QR code and correlative, gap-free numbering per series.
Issued invoices are immutable: they are neither edited nor deleted, only cancelled or corrected with a new record. It supports full and simplified invoices, credit notes, split billing with an insurer, SEPA batches and export for the accountant.
