AEAT certified digitization: ditch paper without risk

What is certified invoice digitization?

Certified digitization is the process by which a paper invoice is transformed into a digital image with the same evidentiary value as the original before the Spanish tax authority (AEAT). It is regulated by Order EHA/962/2007 and allows companies and self-employed workers to destroy the physical document once it has been digitized with AEAT-homologated software. It is critical because it eliminates custody costs, frees archive space and guarantees validity during a tax inspection. For multinationals operating in Spain, AEAT certified digitization software is the only way to fully eliminate paper while remaining compliant with Spanish e-invoicing rules.

AEAT technical requirements (200 dpi, PDF/A, XMP, signature)

For digitization to be valid, the AEAT requires strict technical conditions: minimum scan resolution of 200 dpi, format PDF/A, PNG or JPEG2000 preserving colour and sharpness, inclusion of XMP metadata describing origin and process, electronic signature of every image, and monthly seal of the database to guarantee integrity. The software must be homologated and listed in the official register published by the AEAT. These requirements are non-negotiable: a generic invoice OCR AI tool that does not meet them cannot replace the paper original for tax purposes.

How Dokuflex does it

Dokuflex captures the invoice from mobile, multifunction scanner or email and applies the homologated procedure automatically: resolution adjustment to ≥200 dpi, conversion to PDF/A, XMP metadata generation, electronic signature with a qualified certificate and monthly database seal. The "Doku4Invoices" product is listed as homologated under the Resolution of 24 October 2007. Invoices are retained for the legal limitation period (4 years for VAT, 6 years for commercial documentation) and are exportable at any moment. This is exactly what Spanish e-invoicing compliance looks like in practice: not just an OCR engine, but a fully certified pipeline.

Differences between standard OCR and certified digitization

A standard OCR simply extracts data from the text: useful to speed up bookkeeping, but it does not replace the paper. If you destroy the original without AEAT homologation, the tax authority may refuse to accept the image as evidence during an inspection. Certified digitization, by contrast, does allow you to destroy paper, because it embeds signature, seal and metadata that guarantee integrity. Dokuflex combines both capabilities: invoice OCR AI at 99.4% accuracy to automate bookkeeping, and AEAT-certified digitization to guarantee fiscal validity — the kind of AP automation Spain-based finance teams actually need.

Tax and operational benefits

Savings are threefold: lower custody cost (archive rent, handling, transport), lower risk (loss or deterioration of paper, fines for unreachable documentation) and greater agility (instant search, remote consultation, direct integration with SAP, Sage, A3 or Holded). Facing an AEAT inspection, an image digitized with homologated software has full evidentiary value and simplifies the organisation's document management. Combined with VERI*FACTU readiness — mandatory from 1 January 2027 for corporate-tax entities and 1 July 2027 for self-employed and SMEs — Dokuflex covers the complete chain from supplier email to AEAT submission.

Is Dokuflex AEAT-homologated for certified invoice digitization?

Yes. Dokuflex is homologated by the Spanish tax authority (AEAT) under the product "Doku4Invoices" in accordance with the Resolution of 24 October 2007 (Order EHA/962/2007). You can verify it in the official list of homologated software published by the AEAT. This means invoices digitized with Dokuflex have the same evidentiary value as the original paper document, and the physical copy may be destroyed.

When is VERI*FACTU mandatory for my company?

VERI*FACTU becomes mandatory on 1 January 2027 for entities subject to Spanish corporate tax, and on 1 July 2027 for self-employed workers and the rest of taxable persons. Dokuflex already generates invoice records with chaining, QR code and hash according to the AEAT technical specification.

Can I destroy paper invoices after digitizing them with Dokuflex?

Yes, as long as the digitization is performed with AEAT-homologated software such as Dokuflex. The regulation (Order EHA/962/2007) requires minimum resolution of 200 dpi, PDF/A or equivalent format, XMP metadata, electronic signature and monthly database seal — Dokuflex applies all of this automatically, guaranteeing the same evidentiary value as the paper original.
