Verifactu for attorneys: automatic compliance
What is Verifactu and why does it affect your practice?
The legal obligation
Royal Decree 1007/2023 requires all invoicing software systems to generate immutable records for each invoice via SHA-256 hash chains. Each invoice must be linked to the previous one, making retroactive modification detectable.
Who must comply
Any professional or business issuing invoices using software: attorneys, court clerks, administrative firms, multidisciplinary practices. Sole traders invoicing manually (without software) are temporarily exempt, but the AEAT plans to extend the scope.
How Lexiel handles it automatically
