Anti-Fraud Law

Its goal is to strengthen tax control, ensure traceability of transactions, and promote greater transparency in invoicing processes.
Verifactu, SII, TicketBAI

AEAT Certified Software
This is software that meets the technical and legal requirements established by the Tax Agency to comply with the Anti-Fraud Law. AEAT-certified software ensures compliance under any invoice submission system it integrates (Verifactu, SII, etc.).
Create and Grow Law
The Create and Grow Law is a Spanish regulation aimed at facilitating business creation, boosting growth, and promoting digitalization. The law promotes mandatory use of electronic invoicing as a tool to combat late payments between companies. It also seeks to improve access to alternative financing for SMEs.
Electronic invoice
The electronic invoice is a digital document with legal and tax validity that replaces the paper invoice. The Create and Grow Law requires its use among companies and freelancers to facilitate control, reduce fraud, and improve efficiency and payment timeliness.
