VeriFactu & TicketBAI for Spain

Spain's anti-fraud billing rules require tamper-evident invoices, and this module generates the chained, hash-linked records that VeriFactu and Basque Country TicketBAI demand. Each invoice is fingerprinted with a SHA-256 hash that links to the previous record, forming an unbroken chain the Agencia Tributaria can verify, and a compliant QR code is added to the PDF so customers and inspectors can validate it instantly. The module supports both the national VeriFactu regime and the regional TicketBAI/LROE obligations for Bizkaia, Gipuzkoa and Araba, building the correct XML and signing it as required. Rectifying invoices keep their place in the chain with proper references. Records can be submitted to the AEAT or held in VeriFactu mode, and every document is archived for the legal retention period. It works with multistore and multilingual shops and is compatible with PrestaShop 1.6, 1.7, 8 and 9. Stay compliant with Spain's billing law without changing how you sell.
