VeriFactu responsible declaration: what it is and who signs it
The responsible declaration (declaración responsable) is the document in which the producer of invoicing software states that it complies with the VeriFactu regulation. The producer signs one per version; it replaces a certification that does not exist. FacturAda’s is included in every installation.

What it is and why there is no certification
RD 1007/2023, amended by RD 254/2025, does not create any approval or certification of software. Instead, the producer of the invoicing system must declare in writing, under its own responsibility, that the program meets the requirements. The minimum content is set by article 15 of Order HAC/1177/2024.
