Verifiable invoicing (Spain's Veri*Factu)
Gesthorm's invoicing system meets the requirements of article 29.2.j of Ley 58/2003, General Tributaria (Spanish General Tax Act), and of the Reglamento de Requisitos de los Sistemas de Facturación (RRSIF, the Spanish regulation on invoicing systems). In practice:
- Each invoice is stored in an invoicing record with a hash chained to the previous one.
- Each invoice carries its own QR code.
